Yuanyuan Li, Wei Huo, Wenlong Wang, Huamin Fan


In this paper, the purpose of energy storage battery work cooperatively with power battery has been achieved by using the three port power distributor (TPPD) based on the load isolation type composite power supply system. The logic gate control strategy model is established in MATLAB/Simulink software, and the simulation model of the whole vehicle is established by using ADVISOR to simulate the power supply system of load isolation type composite. The results show that using the logic threshold control strategy to control the energy storage battery and the power battery can effectively reduce the impact of large current on the energy storage battery and improve the service life of the battery pack.
