The Philips Model PE 1701 and the Lester Model 9865 electric vehicle battery chargers have been tested by the Tennessee Valley Authority. Charger input/output voltage, current, power characteristics, and input waveform distortion were measured and induced electromagnetic interference was evaluated while the chargers recharged a fully discharged 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 Philips charger required 12.2 hours to recharge a 144-V battery; it had an energy efficiency of 86.0 percent and a specific power of 87.4 W/kg (39.7 W/lb). Input current distortion was between 6.9 and 23.0 percent, and electromagnetic interference was observed on AM radio. The Lester charger required 8.2 hours to recharge a 106-V battery; it had an energy efficiency of 83.0 percent and a specific power of 117.3 W/kg (53.3 W/lb). Current distortion was between 52.7 and 97.4 percent, and electromagnetic interference was observed on AM radio.
