Test and evaluation of the Brown, Boveri and CIE Veritron electric vehicle battery charger
The BBC Veritron lead-acid battery charger was tested by TVA at its Electric Vehicle Test Facility in Chattanooga, Tennessee. The charger was tested to determine its operating characteristics while recharging an electric vehicle traction battery. The BBC Veritron charger was manufactured by the High-Energy Battery and Electric Vehicle Division of Brown, Boveri and Cie AG in Lampertheim, West Germany. It is a prototype integrated charger/vehicle controller originally constructed for use in the CitySTROMer electric vehicle (EV). The Veritron charger was designed to recharge a 96 volt (48 cell) Hagen Batterie AG 3*5PzS143 lead-acid battery pack which has an automatic electrolyte circulation system. The BBC charger was used to recharge the pack of 16 Hagen 6-volt modules from 100-, 75-, 50-, and 25-percent depth of discharge. Measurements of input current waveform distortion and input and output characteristics, and indications of induced interference with communications equipment were made during the tests. In addition, physical characteristics and the manufacturer's nameplate ratings were recorded. As a figure of merit for use in comparing different chargers, the specific power (maximum continuous output power divided by charger weight) was calculated. Electrical measurements were made using precision volt-ampere-watt meters, frequency counters, a digital-storage oscilloscope, and a spectrum analyzer. Differential amplifiers were used to convert ungrounded high-voltage inputs to ground-referenced outputs and to provide magnitude scaling and low-pass filtering, where necessary, of the signals input to the test instruments. A discussion of the test procedures and instrumentation is included in Section 2. A description of the BBC charger is included in Section 3 and detailed test results are presented in Section 4. 6 refs.
