• Advance DC Machines
• Development of DC controllers
• Battery conditioning tests
• Battery technology scans
• Life cycle testing
• Analysis of failures and costs
So what has changed to date

High Costs of Infrastructure
Actual habit of PEV vehicles : Where would we charge?

Localization of Market
Multiple customers in the same area
•Upgrade of Lines transformers
•Substations
•Potentially new generation and transmission capacity

Present Loading 7.5 x 40 = 300 KVA
Assume 5 KW = Additional Load 200KVA – Max load now 500KVA
Impact on Peak Loads
• Different charging options
• Unmanaged Charging
• Controlled charging
• Time of Use charging
• Smart Charging

Business Models
• Utility owns EV charging equipment
• Subsidy from Utility
• Consumers ownership

Why do we need to do this research
• PEV potentially will have an impact in all aspects of Eskom business
• Regulation and policy within Eskom need to understand the legislation impacts
• New tools required by engineers and planners on forecasting
• Tools and process may need to be aligned to better manage the distribution network.
• Impact to the IDM from a demand management perspective.
• Smart grid implications on network architecture
• New real time customer information and billing systems
• Network support skills for new electrical infrastructure
• Potential of using EV as Eskom Fleet
