Vehicle Battery Testing - Fast Charging Effects

Fast Charging Effects

Fast Charge Effects on Battery Life and Vehicle Performance Study

Four model year 2012 Nissan Leaf battery electric vehicles were instrumented with data loggers and operated over a fixed on-road test cycle. Each vehicle was charged twice daily, with two vehicles charged at AC Level 2 (L2), and two DC fast charged (DCFC) with a 50kW charger. The traction battery packs were removed and tested when the vehicles were new, and at 10,000 mile intervals. Battery tests included constant current discharge capacity, electric vehicle power characterization, and low peak power tests. The testing was halted at 63,000 miles.
