HEV再生制动时电池快速充电模糊控制策略
Fuzzy control strategy of battery fast charging in regenerative braking for hybrid electric vehicles
摘要
Abstract
In order to improve the charging efficiency of the hybrid electric vehicle (HEV) batteries during regenerative braking and ensure its safety, based on the analysis of the heat-transfer model for the battery charging process, the mathematical relationship between the open circuit voltage-internal resistance model and the charge efficiency is first established. Then a fuzzy control algorithm of battery fast charging is designed based on the Malus law. The simulation model of closed-loop control system is established in Matlab. Finally, by modeling and simulation, the rate of electric energy recovery for HEV is calculated with different control strategies. It is shown that the rate of electric energy recovery with the fuzzy control strategy is increased by 8. 41% compared with the constant current charge method in the same brake condition.关键词
