Battery Testing in the US
Battery performance and life testing in the US is an application-driven, analytical
process
Current focus is on HEVs, PHEVs and EVs
For simplicity, this presentation will be focused on test methods for PHEVs and EVs
at the pre-competitive stage
General testing philosophy
– Obtain sufficient information in a limited amount of time to gauge the performance of a
battery without exhausting it
– The test procedures employ accelerated aging techniques
– The test procedures used are applicable to cells, modules and complete battery systems
Anatomy of battery testing
– Characterize the performance of a battery
– Age it under controlled conditions
– Measure changes in performance by repeating portions of the characterization tests
• A reference performance test
Vehicle Stress on Battery
Each type of electric vehicle uses the capacity/energy of the battery differently
– EV: use about 80% of available battery energy for vehicle propulsion (all electric range,
AER)
– PHEV: use about 70% for electric propulsion (high SOC, AER) and about 5% for hybrid
operation (low SOC)
– HEV: use about the central 50% of the battery for operation (charge sustaining)
Thus, the battery has to be sized and engineered to accommodate demands from
the vehicle
