Universities Power Battery Grading System 1 Channel For EV

Neware Power Battery Formation and Grading System EV Battery Cycle Life Tester

Based on Neware fifth - generation testing system . Mainly used in Power battery condition simulation , Pulse charging and discharging , Cycle Life , Rate of charge and discharge .

Using dynamic power or current waveform to simulate electric vehicle driving road . Simulate the electric vehicle driving road conditions through the dynamic power or current waveform .

CT-4000 mainly applies for institutions , colleges and universities and EV battery manufacturers .

Driving Cycle Simulation

Driving cycles are used to simulate car fuel economy at different operating conditions . There are many driving schedules or driving cycles that are issued by various agencies or institutes. To simulate EV , you need to convert the speed output into the power consumption or regeneration of the energy storage device installed on the vehicle .

Accurate Timing

Capacity or energy is calculated on time basis with the voltage and current measured , thus the timing accuracy will greatly affect the capacity calculated . To a general constant current or other constant testing regimes, this effect may not that easy to be observed . 

Recycle Battery Function

If you have recovery battery pack , like Toyota Prius battery pack , generally, each piece has 6 single Ni - MH cell , then several pieces batteries assembed in one pack , and you need to check each single cell for capacity , cyclie life , resistance , etc . Then assemble the battery cell after sorting by capacity , resistance . You will get the new battery pack . And last you will test the battery pack to check the real capacity and other function parameter . 

Simulation - the Way You Look into Reality

You know battery capacity at at constant current , or power , or load . But the reality is that no the energy is drawn by a constant variable . Your capacity or energy tested under constant conditions can only be a general one , and the cycle life tested such regime can also be largely deviated from reality . To have a better master of reality, simulation is introduced . GSM pulse is of such kind for phone batteries . for EV batteries , Drive Cycle Simulation is used .
