The invention discloses a battery charging control method for a tandem hybrid electric vehicle, and the method comprises a control architecture which is divided into three modules: an energy management working condition recognition module, an energy management decision calculation module and an energy management execution module. The working condition recognition module is responsible for judging the running state of the whole vehicle and the intention of a driver. By monitoring the SOC of the battery, the power demand of a driver of the whole vehicle and the electric power of high-voltage accessories, the vehicle economy, the dynamic property and the drivability of the whole vehicle are considered, the battery discharge depth is maximized, electricity is used as much as possible when the electric quantity of the battery is high, electricity is used as little as possible when the electric quantity of the battery is relatively low, and when the battery is fed, the service life of the battery is prolonged. And the advantage that the energy of a series hybrid configuration can be flexibly allocated is fully utilized, and the optimal whole vehicle dynamic property, drivability and vehicle economy are achieved.
本发明公开了串联式混合动力电动汽车电池补电控制方法,包括控制架构,所述控制架构分为三个模块,分别为能量管理工况识别模块、能量管理决策计算模块和能量管理执行模块;所述工况识别模块负责对整车运行状态,驾驶员意图进行判断。本发明通过监控电池SOC,整车驾驶员动力需求,高压附件用电功率,兼顾了整车用车经济性,动力性和驾驶性,在不影响电池影响寿命的情况下,最大化电池放电深度,在电池电量高时,尽量多用电,在电池电量相对较少时,相对少用电,在电池馈电时,及时为电池补电,充分利用了串联式混动构型的能量可灵活调配的优势,实现了最优的整车动力性、驾驶性和用车经济性。
