Lithium battery ultra-capacity hybrid energy storage introduction
Abstract -A new ultracapacitor/battery based hybrid energy storage system (HESS) is proposed for hybrid and electric vehicles by using both renewable and non-renewable resources, Compared to the conventional HESS design, which uses a larger dc/dc converter to interface between the ultracapacitor and the battery/dc link to satisfy the real-time high power density demands during high speed operation, the proposed design uses a much smaller dc/dc converter working as a controlled energy pump to maintain the voltage of the supercapacitor at a value higher than the battery voltage for the most city driving conditions.
