Abstract :
This paper presents a method to optimize the on-board energy system of electric vehicle in the aspect of electro-load characteristics. LiMn2O4 Battery (14.8V 100Ah) is used as low voltage energy system instead of the original lead-acid battery (12V 70Ah). The power battery system is divided into two parts, which are placed under the vehicle chassis and in the car trunk, respectively. The power battery system and low voltage energy system can be charged with the on-board charger. The low voltage battery charging is also optimized by solar cell in order to save energy.
