The Parameters Matching and Simulation of Pure Electric Vehicle Composite Power Supply Based on CRUISE

Abstract

Pure electric vehicles develop rapidly all over the world. According to building the model of pure electric vehicle in the CRUISE software, first the power supply system parameters are designed and simulated, and then the power performance and feasibility of the model are verified. The design of CPS (composite power supply) which combined UC (ultra capacitor) with Li-B (lithium battery) can extend the life of the Li-B, and protect the Li-B in some way. Under the NEDC operating condition, the simulations of the SPS (single power supply) and the CPS are taken. The result shows that the variation of the Li-B SOC decrease by 8%, compared the CPS system with the SPS system, the comprehensive energy consumption economy is 6.25%.
