3. Stakeholders’ feedback to consultation 3.1 A First Consultation was initiated on 13 July 2016 requesting stakeholders’ feedback by 9

August 2016.

3.2 This section sets out the feedback received during the consultation process together with the Bureau’s response on how the issues and points raised shall be addressed. Some of these points were discussed with Stakeholders during the First Workshop and are hereby included in its final form as part of this public consultation.

Radial Circuit of EV Charging Mode-1

Stakeholder’s feedback

3.3 ADDC and DMA&T, referring to clause 1.37, highlighted that radial circuit is not applicable to Mode-1 installation as it could be a normal domestic socket in a garage and that possibly would not be connected in a Radial Circuit but rather as a part of an existing ring circuit.

Bureau’s response

3.4 The Bureau intends to ban Mode-1 installation for EV charging due to the lack of safety measures associated with this mode of charging. Hence, the Regulations and the Installation Guidance will not allow the use of Mode-1 to charge EV.

3.5 Having a dedicated radial circuit for EVSE is a mandatory requirement under the proposed Addendum. For existing Premises, Owners through a licensed contractor will need to add or secure a radial socket circuit for a minimum of Mode-2 EV charging.

Proposed resolution

3.6 Mode-2 installation would be the only permitted mode of charging at homes via normal socket outlets; whether the socket outlet was fed from a single phase or three-phase connection. Mode-2 installation involves an in-cable control box which provides better safety to the people and to the EV.

3.7 A note is included in both the updated draft Regulation and the update draft Installation Guidance to reflect these changes

Drawings Approval and Inspection of EV Charging Mode-1 & Mode-2:


3.8 ADDC and DMA&T highlighted that drawings approval and inspection are not necessary for Mode-1 & Mode-2 installations, as it will put up unnecessary barriers for customers wanting to charge vehicles in their own homes.


Page 8 of 17

Bureau’s response

3.9 The Bureau intends to ban Mode-1 installation. Hence, the Addendum and the Installation Guidance would not anymore cover Mode-1 Installation.

3.10 In case of installing new EVSE in existing Premises, owners must comply with Regulation 3.3 (concerning extensions, alterations and repairs) in the Electricity Wiring Regulation (Third Edition).

3.11 Refer to clause 2.1.53 in the Electricity Wiring Regulation (Third Edition) for Premises definition.

Proposed resolution

3.12 Mode-2 installation will be the only permitted type at homes via normal socket outlets; single phase or three-phase.

3.13 A note is included in both the updated draft Addendum and the updated draft Installation Guidance to reflect these changes.

3.14 EVSE Owners will need to notify the Distribution Company in case of any extensions, alterations and repairs within their Premises in line with the requirements of the Electricity Wiring Regulations (Third Edition), Regulation 3.3.

3.15 EVSE Owners are Property owners or EV charging companies who wish to own, operate and maintain EVSE and provide Charging service to EV Drivers.

3.16 Owners will need to approach the Distribution Company for approval in case of increase to the total Connected Load of greater than 10% at the Premises, or greater than 10% of the Connected Load at any Distribution Board.

Ownership and Tariff rate of EVSE


3.17 What agency will be responsible for the energy used by the building or site? What is the tariff rate? Who is the leading agency for operation and maintenance of the EVSE?

Bureau’s response

3.18 The Bureau’s view is that the ownership, operation and maintenance of EVSE is not a “regulated activity” pursuant to Article 71 of Law No (2). Accordingly, EVSE owners do not need to seek a licence from the Bureau and the Bureau will not price regulate this activity. The service charge/rate will therefore be left to the market to decide.

3.19 However, the operation and maintenance of EVSE is an area where the Bureau can, under Articles 62 to 66 of Law No (2), issue technical regulations. This includes for the following purposes:

(a) to protect the general public from danger related to electricity (Article 63(2));

(b) to eliminate or reduce the risk of personal injury (Article 63(3));


Page 9 of 17

(c) to ensure that electricity fittings installed are safe (Art.63(8)); and

(d) to promote the conservation and efficient use of electricity (Art.63(9)).

3.20 Accordingly, the Bureau is minded to issue technical regulations in this area. In relation to tariffs specifically, the Bureau proposes that electricity supply to the EVSE will be monitored and billed by ADDC/AADC meters with tariffs according to the Premises type in which the EVSE will be connected.

Proposed resolution

3.21 The Distribution Company will monitor and charge EVSE Owners based on the meters installed before the EVSE under tariffs according to the Premises type in which the EVSE will be connected.

3.22 The service charge or rate for the provision of EV charging services through EVSE to end users will be determined by the EVSE Owners. EVSE owners will need to comply with the Bureau’s technical (and other regulations) issued pursuant to Article (62) as well as any other requirements by the Department of Economic Development or any other applicable legal or regulatory requirements in Abu Dhabi),.

3.23 EV Drivers are owners of purely Electric Vehicle or any other vehicle types that has plug in charging feature i.e. Plug in Hybrid Electric Vehicle (PHEV) and Extended Range Electric Vehicle (EREV).

Supply License or Exemption by the Bureau


3.24 ADDC raised a concern that the approach of licensing or exempting the owner of the EVSE to supply Electricity will put up unnecessary barriers for organization wishing to provide charging facilities for their employees at the workplace or for public use in mall, carparks, etc.

Bureau’s response

3.25 See above regarding the Bureau’s view on the application of Law No (2) to this activity.

3.26 On the basis of this legal view, EVSE licensing requirement proposed earlier is no longer applicable under this proposed market structure.

3.27 The Bureau considers that market forces will drive the required level and quality of services in this area, provided that sufficient competition exists in the market which will ensure consumer protection.

3.28 We note that, under the proposed market approach, ensuring fair pricing, market competition and customer protection would fall under the scope of the Department of Economic Development.

Proposed resolution

3.29 For new installation, EVSE owners shall follow the same steps outlined in the Electricity Wiring Regulation, third edition for Electrical Installation Regulation 3.2. The same is illustrated under annex-A in the installation Guidance.

3.30 For installation in existing Premises, EVSE Owners shall follow the instructions under Regulation 3.3 in the Electricity Wiring Regulation, third edition.

Approved Suppliers and Contractors


3.31 Approved Vendors/Suppliers & Contractors for the supply and installation of EVSE should be established.

Bureau’s response

3.32 The Bureau proposes that the approved Vendors/Suppliers List shall be maintained by QCC.

3.33 Furthermore, the list of Licensed Contractors shall be maintained by AADC/ADDC, similar to other electrical works.

Proposed resolution

3.34 QCC shall develop and maintain a list of vendors/suppliers of EVSE and accessories through a conformity programme.

3.35 The existing licensed contractors list maintained by AADC/ADDC shall cater for the installation of the EVSE.

Troubleshooting


3.36 UPC highlighted that the addendum should include a section on the troubleshooting requirements for EVSE users.

Bureau’s response

3.37 Troubleshooting is an activity within either commissioning or maintenance of EVSE. The Electricity Wiring Regulation, Third Edition, does not cover the troubleshooting part of electrical equipment. Hence, it is outside the scope of this addendum to cover the troubleshooting aspect.

Proposed resolution

3.38 Troubleshooting is an activity within either commissioning or maintenance and that is typically covered under Manufacturer’s Manual. The same is reflected under clause 1.34 in the update draft Addendum.


Page 11 of 17

Solar Powered Vehicle Charging Points


3.39 UPC suggested to study the option of having electric vehicle charging points powered by PV with storage batteries.

Bureau’s response

3.40 The Electricity Wiring Regulation, Third Edition, covers the technical requirements of PV systems that are connected to the utility grid without storage batteries.

Proposed resolution

3.41 Whoever wishes to install Solar PV Powered EV charging points with Storage Batteries will need to approach AADC/ADDC for review and approval.

Environmental condition


3.42 UPC highlighted that EVSE should be properly specified for the site conditions including; heavy-duty or light-duty, interior or exterior placement, wet or dry conditions, and extreme temperatures.

Bureau’s response

3.43 The reason behind not specifying the environmental conditions in the Addendum is that they are covered under the Electricity Wiring Regulation, Third Edition, clause 3.7.1.

Proposed resolution

3.44 Designers and contractors need to comply with Electricity Wiring Regulation, Third Edition, specifically clause 3.7.1 for environmental conditions and relevant clauses in the Addendum.

Distribution Pillar


3.45 ADDC requested more clarification on the distribution pillar (shown under the installation guidance Annex-D) with respect to the supply of those pillars and whether they are standardized or customized items.

Bureau’s response

3.46 The distribution pillars are simply distribution boards for EV charging equipment, these would be supplied as part of the installation (similar to any Final DB, Sub Main DB or Main DB) . Hence, the owner will be the same for both the EVSE and the distribution pillar(s).


Page 12 of 17

3.47 ADDC/AADC will need to fix their meters as per their current specification and requirements either inside those distribution pillars/boards or a separate metering cabinet (i.e. similar to Premises metering arrangement).

Proposed resolution

3.48 The Distribution Company meters installed on or close by the distribution pillar will need to be accessible by the Distribution Company.

3.49 Contractors shall be required to provide the necessary support/structure to fix the Distribution Company’s meter box.

3.50 The EVSE owner shall be charged based on the readings from those meters fixed on or close by the distribution pillars.

Regulations.

4.2 The Bureau also invites the public to provide their views and comments on the draft EVSE Installation Guidance document.

4.3 The following section summarises some additional areas of consultation as part of the Second Consultation.

Approved suppliers/vendors list 4.4 Development of approved suppliers/vendors list by QCC for EVSE and its accessories.

4.5 QCC is invited for views on this.

Banning of charging Mode-1 4.6 The Ban of Mode-1 installation due to its potential hazard especially when EV car

batteries are fully charged due to the absence of second line defence in case the on-board charger fails.

Market structure 4.7 Supply of electricity to end users through EVSE is not a regulated activity for the

purposes of Law No 2 of 1998, and as such will not require licensing or be subject to price regulation from the Bureau.

4.8 EVSE ownership is open to the market competition which includes facilities’ owners and EV charging equipment companies.

Metering and billing 4.9 The distribution company’s meters will be installed on or close by the distribution pillars

and from that the bill is calculated.

4.10 The tariff rate on the distribution company’s meters will be according to the Premises type in which the EVSE will be connected.

4.11 Pricing for the supply of electricity to end users through EVSE is not price regulated by the Bureau. The EVSE owners will charge their customers on any rate they would choose i.e. AED/kWh or service value subject to any applicable legal or regulatory requirements (for example from the Department of Economic Development).

Solar PV powered EVSE 4.12 The Distribution Company will need to review and approve any application with regard to

EV charging points powered by Solar PV with Storage Batteries.

Abu Dhabi.

1.4 This Addendum 1:2016 shall be effective from 1 January 2017.

Definitions

[Note: In addition to the definitions in this section, all listed definitions

and notes in Chapter 2, Definitions, of the Electricity Wiring Regulations

(Third Edition), are also applicable to this Addendum.]

1.5 Addendum: Addendum 1:2016 to the Electricity Wiring Regulations

(Third Edition), as amended by the Bureau form time to time.

1.6 Charging Modes: An operating mode in which energy transfer from a

power source to the Electrical Vehicle’s (EV) battery; below are

related definitions:

a) Mode-1: Connection of the EV to the a.c. supply network utilising

standardised socket-outlets not exceeding 16A and not exceeding

a nominal supply Voltage of 230V a.c. single-phase or 400V a.c.

three-phase, at the supply side, and utilizing the power and

Circuit Earth Conductors (according to BE EN 61851-1). Mode 1

is more appropriate for home or office charging where the

charging period is relatively long, typically 6 to 8 hours.

b) Mode-2: Connection of the EV to the a.c. supply network utilising

standardised socket-outlets not exceeding 32 A and not exceeding

a nominal Voltage of 230 V a.c. single-phase or 400 V a.c. three-

phase, at the supply side, and utilizing the power and Circuit Earth

Conductors together with a Control Pilot function and system of

personnel protection against electric shock (RCD) between the

EV and the plug or as part of the In-Cable Control Box.

c) Mode-3: Connection of the EV to the a.c. supply network utilising

dedicated EVSE and a charging cable assembly. The control pilot

cable of the charging cable assembly allows communication

between the EVSE and the On-Board Charger of an EV platform

functions including verification of connection with the EV,

continuous checking of Circuit Earth Conductor integrity,

energisation and de-energisation of the supply and selection of

charging rate. The charging equipment are typically in the form of

charging posts or wall mounted charging units, and come in a

variety of current ratings e.g. 13A, 16A, and 32A and 250A.


Addendum 1:2016

2 Addendum 1:2016


d) Mode-4: Connection of the EV to the a.c. supply network utilising

an Off-Board Charger where the Control Pilot function extends to

control equipment permanently connected to the a.c. supply. In

this Mode, Direct Current Electrical Power is delivered to the

vehicle. In Mode-4 either a single-phase or three phase a.c. is

converted to d.c. within the EVSE. Such charging equipment units

are considered not to be suitable for domestic Electrical

Installations due to the higher Voltages and currents used

(typically, 500V, 125A).

1.7 Control Pilot: The control conductor in the charging cable assembly

connecting the In-Cable Control Box or the fixed part of the charging

facilities, and the EV earth through the control circuitry on the vehicle.

It may be used to perform several functions.

1.8 Electric Vehicle (EV): Any vehicle propelled by an electric motor

drawing current from a rechargeable storage battery or from other

portable energy storage devices (rechargeable, using energy from a

source off the vehicle such as a residential or public electricity

services), which is manufactured primarily for use on public streets,

roads or highways such as battery electric vehicles, hybrid vehicles,

plug-in hybrid vehicles, and extended rang electrical vehicles.

1.9 Electric Vehicle Supply Equipment (EVSE): Conductors, including

the phase, neutral and Circuit Earth Conductors, the EV couplers,

attachment plugs, and all other accessories, devices, power outlets or

apparatuses installed specifically for the purpose of delivering energy

from the Premises wiring to the EV and allowing communication

between them if required. Example: wall-box unit and charging pole.

1.10 In-Cable Control Box: A device incorporated in the charging cable

assembly, which performs control functions and safety functions. Such

functions include RCD, over-current, over-temperature, and

protective Earth detection.

1.11 Off-Board Charger: Charger connected to the Premises wiring of the

a.c. supply network (mains) and designed to operate entirely off the

vehicle. In this case, direct current electrical power is delivered to the

vehicle (e.g. Mode 4).

1.12 On-Board Charger: Charger mounted on the vehicle and designed to

operate only on the vehicle.

1.13 Vehicle Coupler: Means of enabling the manual connection of a

flexible cable to an EV for the purpose of charging.

1.14 Vehicle Connector: Part of a Vehicle Coupler integral with, or

intended to be attached to, the flexible cable connected to the a.c.

supply network (mains).

1.15 Vehicle Inlet: Part of a Vehicle Coupler incorporated in, or fixed to,

the EV or intended to be fixed to it.

1. Introduction Purpose and Statuary requirements 1.1 The purpose of this guidance document is to introduce the basic knowledge and the

technical requirements for installing Electrical Vehicle Supply Equipment (EVSE) by

Licensed Contractors. It also serves as an informative reference to the general public in

the Emirate of Abu Dhabi.

1.2 This guidance document should be read with other regulations issued by the Bureau:

Electricity Wiring Regulations, Third Edition

Addendum 1:2016 to the Electricity Wiring Regulations, Third Edition

1.3 This guidance document applies to all new charging facilities in the Emirate of Abu

Dhabi.

Overview 1.4 The rapid developments and improvements in the technologies of EV batteries let to

increased popularity in this type of vehicle, so the development of infrastructure of

charging stations at home, commercial and public locations become very important. The

basic components of any EV charging infrastructure are: (1) electrical power supply from

the Distribution Company, (2) on-site wirings, and (3) charging stations.

1.5 EV owners or users need to have a solid understanding of EV charging equipment types

and operation, so they can select the appropriate EVSE product and choose the right

Licensed Contractor for proper installation.

1.6 For the economy and convenient of home charging, EV owner will assume the

responsibility of installing a residential charging station in his/her garage with close

coordination with the EV and EVSE manufacturers. However, to extend the driving range

of EV and to enable practical driving patterns, further EVSE should be available at

commercial and public locations.

2. Electrical Vehicles Technology

2.1 Types of Electrical Vehicles

2.1.1 This section introduces the types of most common electrical vehicles that are

available in the marketplace. The focus of this section is on street electrical vehicles

that incorporate a battery energy storage device that can connect to the electrical

distribution network for the supply of some or all of its fuel energy requirements.

2.1.2 The information provided in this section should increase the basic understanding of

battery electrical vehicles and how they work with EVSE, which should leads to better

planning and installation.

2.1.2.1 Hybrid electric vehicles (HEV)

HEVs have two motors: an internal combustion engine (IECICE) and an electric

motor. Their storage batteries are generally low-capacity, which greatly limits their

range and top speed in electric mode. HEV batteries are charged by the ICE or other

propulsion source and during regenerative braking, so they cannot be recharged

from the distribution network therefore not covered by this Guide. Example: Toyota

Prius and Honda CR-Z

2.1.2.2 Plug-in hybrids (PHEV)

PHEVs are hybrids that can be plugged into the distribution network for battery

charging. In general, they have a medium-capacity battery that allows the vehicle, in

all-electric mode, to achieve a range of several dozen kilometres, and rates of

acceleration and top speeds comparable to those of gasoline-powered vehicles.

Example: Chevrolet Volt, Ford C-Max, Cadillac E L R and Toyota Prius PHEV.

2.1.2.3 Battery electric vehicles (BEV)

BEVs operate solely on the electricity stored in a high-capacity battery, which can be

recharged from the distribution network. Depending on battery capacity, they have a

range of 100 to 400km; charging time varies by battery capacity and whether, it is

also affected by the ambient temperature and the remaining battery charge at the

start of charging. Typically, a fast-charge station is used for this type of electrical

vehicle. Examples: Nissan LEAF, Tesla Model S.

2.1.2.4 Extended range electric vehicles (EREV)

EREVs are battery electric vehicles equipped with an internal combustion generator

that produces enough power for the vehicle to reach a charging station when its

battery is depleted. Example: BMWi3

3. Overview of charging stations

3.1 General overview

3.1.1 A charging station or an EVSE is typically a stand fixture, which is fed directly from a

distribution panel or from a dedicated electrical socket-outlet. An EVSE can have one

or more charging cable. A display screen or a set of colourful lights that indicate the

charging status. An EVSE may also have Start/Stop push-buttons for charging

operations. It can also include electronic payment system, energy meter and

internet/wireless communication.

3.2 Height of EVSE controls and socket-outlet

3.2.1 The lowest part of any EV charging socket or EVSE controls shall be located

between 0.5m to 1.5m above the ground.

3.2.2 To protect the EV charging socket or EVSE from vehicle bumpers and to allow users

with disability to easily reach the charging equipment, it is recommended that the

EVSE to be installed between 0.75m and 1.2 m above the ground.

3.3 Charging Modes

3.3.1 There are four (4) different modes of conductive charging for Electrical Vehicles as

specified by IEC 61851 (Electrical Vehicle conductive charging system):

3.3.1.1 Mode 1 - For Mode 1 charging, an AC charging current is delivered via a

standard socket outlet e.g. BS1363 13A and a charging cable without

communication function to the on-board charger of the EV. The presence of a

Residual Current Device (RCD) for shocking protection is a must on the

supply side of the fixed electrical installation. This mode of charging is

suitable for longer period of charging at home or office.

3.3.1.2 Mode 2 - For Mode 2 charging, an in-cable control box is incorporated into

the charging cable assembly. The provision of fixed electrical installation for

charging facility is similar to that for Mode 1 except that the final circuit,

protective device and socket outlet shall be of a suitable rating to cater for the

higher level of charging current not exceeding 32A.

3.3.1.3 Mode 3 - For mode 3 charging, dedicated EV supply equipment (EVSE) and

a charging cable assembly shall be employed. The control pilot cable of the

charging cable assembly allows communication between the EVSE and the

on-board charger of an EV to perform functions including verification of

connection with the EV, continuous checking of protective earth conductor

integrity, energization and de-energization of the supply, and selection of

charging rate.

KK/AF

Page 10 of 20

3.3.1.4 Mode 4 - Mode 4 charging employs the principle of using an off-board

charger to deliver a DC current directly to the battery bypassing the on-board

charger. DC quick charging can charge up an EV in a relatively short time as

a substantially higher electrical power ranging from 20kW to 120kW is used.

4. Planning

4.1 General requirements

4.1.1 Various locations can be suitable for EVSE such as business and government sites

as well as petrol stations and parking lots/structure. The selected EVSE location

should be convenient and highly visible and available to a large number of EV

drivers.

4.1.2 The location and capabilities of the EVSE (charging mode) should match the needs

of the EV drivers visiting the charging station. For example visitors to a shopping mall

may park his/her EV for several hours while shopping, thus mode 3 or 4 are most

appropriate for this location. Mode 1 or 2 may be more suitable for longer period of

parking such as office parking, home garage or airport parking. Mode-1 charging is

not permitted due to the lack of safety measures associated with this mode of

charging

4.1.3 The installation of EVSE should adhere to UPC’s Estidama requirements, Urban

Streets Design Manual (USDM) and Public Realm Design Manual (PRDM) and other

as applicable

4.1.24.1.4 Electric Vehicle Supply Equipment (EVSE) shall be integrated within the “Right of

Ways” (ROWs) as per the UPC’s Manual and the relevant agencies requirements to

avoid any impacts that might be resulting on the ROWs and its user.

4.2 Physical installation requirements

Consider the following criteria in selecting the physical location for an EVSE:

Configuration of the charging station such as the charging mode and number

of charging cables (single/dual);

Location of underground tanks or utility services when planning for excavation

work;

The expected number of EV drivers and the potential traffic around the

charging station;
