The Hoppecke Model E240 G 144/16 electric vehicle battery charger was tested by TVA. Charger input/output voltage, current, and power characteristics and input waveform distortion were measured and induced electromagnetic interference was evaluated as the charger recharged a lead-acid battery pack. Electrical quantities were measured with precision volt-ampere-watt meters, frequency counters, a digital-storage oscilloscope, and a spectrum analyzer. The Hoppecke charger required 12.2 hours to recharge a 144V battery from 100% depth of discharge (DOD). Energy efficiency was 82%, specific power was 81.2W/Kg (36.8W/lb), input current distortion varied from 52.6 to 73.6%, and electromagnetic interference was observed on AM radio. Charge factor was 1.25 from 100% DOD, increasing to 1.52 from 25% DOD.
