Abstract :
A new battery configuration technique and accompanying control circuitry, termed a synergetic battery pack (SBP), is designed to work with lithium batteries, and can be used as both an inverter for an electric vehicle AC induction motor drive and a battery charger. In this paper, the authors compare the performance of the synergetic battery pack as a battery charger with several simple conventional battery charging circuits via computer simulation. The factors of comparison were power factor, harmonic distortion and circuit efficiency. The simulations showed that the SBP is superior to conventional charging circuits since the power factor is unity and harmonic distortion is negligible
