复合电源能量控制策略研究
Study on energy control strategy of hybrid power system
摘要
Abstract
To reduce the battery damage due to the high current,the super capacitor is added to the power system of the pure electric vehicle.Based on the low limit of the discharge and the high limit of charge of the super capacitor and the constant discharge power of the battery,SOC value,state of super capacitor and demand power were used as control variables with controlling by the DC/DC,the constant power output of the battery was changed to inconstant power for the vehicle drive by the super capacitor.The control strategy model was built in Matlab/Simulink and the vehicle model was built in Cruise for the united simulation.The simulation results show that the matching of the super capacitor and the design of control strategy meet the requirements,and can be very good to optimize the battery output and prolong the service life of battery.关键词
