Fast Rise Time and Bipolar

• Bipolar control without zero crossing dead zone (current and voltage)

• Guarantees cross zero linearity

• Advantage over other products on the market, which can not apply or control desired value when current or voltage is close to zero, such as within 2% of the maximum current.

Reverse Charge Technique



Voltage Clamp

• A maximum voltage limit on charging or minimum voltage limit on discharging are applied through hardware

• As it is a hardware function, voltages can not exceed these limits even if software hangs up or communication is lost

Traditionally, auxiliary inputs are dedicated to a main channel. As a result, many auxiliary inputs will be needed for every possible usage on every channel. Virtual mapping enable user to assign any single or group of auxiliary inputs to any main I/V channel. Any auxiliary input can also be assigned to several main I/V channels.As result, only small number of input channels may serve for large number of main channels and can be more creative and more flexible in the application

Protection of files by creating password



Specific functions

• 1. Using Simulation Control, the user programs a 1 step schedule that tells the Arbin system to control current, voltage, or power based on a text file. In the text file is simply data about current, voltage, power vs. time. The Arbin system will apply the current (or voltage or power) profile according to the data in the text file.

• 2. Formula feature: Software should allow the user to control a test using variables rather than concrete control values (for example, instead of using 4.2V for control, the system should be able to use “Last Step Maximum Voltage” as the control type for the following step. It must also be possible to use these variables in a formula to control the system (For example, “Stop the charge step when FORMULA A falls below -0.1 where FORMULA A = PRESENT CHANNEL VOLTAGE – MAXIMUM CHANNEL VOLTAGE)…..or something. Formulas should have: ABS, COS, ACOS, SIN, ASIN, TAN, ATAN, CEILING, CUBIC, EXP, EVEN, FACTOR, FLOOR, INT, LN, LOG10, ODD, RANDOM, SIGN, SQUARE, SQRT, and TRUNCATE function commands in addition to the normal operators (+ - * /).

• 3. C-Rate: It should be possible to program test profiles using C-RATE so that a single test schedule many be performed on different sizes of batteries. The user programs the schedule based on C-RATE and then when assigning that test schedule to the channel the test will be performed on, they also enter the capacity of the battery that the schedule will be assigned to.

• This prevents the customer from having to write a different schedule for every size battery they use when the test that they are performing is the same except for current values.

• 4. On-the-fly test schedule modification: The user should be able to make modifications to the test schedule while the test is currently running – without stopping or pausing the test. Changes are applied immediately upon saving the schedule.

• For example, you write a test schedule and run it on a battery. While monitoring the data real time, you notice that the current value you programmed should actually be a different value. With the test running, you simply open the schedule and change the current value. You then save the schedule and the change is applied instantly to the running test.



Specific functions

5. System should have the following control types (standard):

• Constant Current – user sets current value (or variable or function)• Constant Voltage – user sets voltage value (or variable or function)• C-Rate – user sets C-Rate value (Ex. C/4….)• Rest (OCV)• Constant Power – user sets power value • Constant Load – user sets load value (Ohms)• Current Ramp – user sets starting current value and ramp rate (A/sec)• Voltage Ramp – user sets starting voltage value and ramp rate (V/sec)• Current Staircase – user sets starting current value, current step value, and stair time value• Voltage Staircase – user sets starting voltage value, voltage step value, and stair Time• Current Pulse – user defines sub-second pulse with up to 10 stages (current and time per

stage). Pulse can be run once or repeated for a certain length of time• Voltage pulse - user defines sub-second pulse with up to 10 stages (voltage and time per

stage). Pulse can be run once or repeated for a certain length of time• Current Simulation – user assigns data text file with current vs. time data – system follows data

file• Voltage Simulation – user assigns data text file with voltage vs. time data – system follows data

file• Power Simulation – user assigns data text file with power vs. time data – system follows data

file• Internal Resistance – user assigns amplitude and offset – system automatically runs DC internal

resistance measurement based on current interrupt method and generates resistance value



Data Export and Handling

Monitor screen is the main interface between machine and user. 4 monitor screens are provided for convenience of use.

The detail view provide real time data and information, one line for each channel. It include date, time, test name, schedule name, step#, current, voltage, energy, capacity, power, load…. This is the main screen for user to quickly scan each channels information.The brief view give a glance of all channels of their status. Each channel is represented with a small square box and color codes represent status such as charge, discharge, stop…Graph view plot test curves of a number of channels for certain period of time up to the moment. It is convenient to check the test trend of several channels through this view.Channel view present all available data of one channel on one screen, including SMB data. User does not need to scroll the screen like in the detail view.
