The invention provides a vehicle charging and discharging method, a battery management system and a charging and discharging system.The method comprises the steps that when it is detected that a vehicle is inserted into a charging gun, charging information interaction with a direct current charging pile is carried out, and if it is determined that charging preparation conditions are met, the vehicle enters a charging state; a discharging request sent by the vehicle-mounted charger is received, a charging and discharging power balance strategy is executed according to the discharging request, and the charging and discharging power balance strategy is used for avoiding charging interruption and discharging interruption; therefore, when the vehicle is charged, the external load can be discharged, and a charging and discharging power balance strategy is executed, so that discharging interruption and charging interruption are avoided; and the discharge efficiency is improved, so that the use experience of a user on the discharge function is improved.
本发明提供了一种车辆充放电方法、电池管理系统及充放电系统,方法包括:当检测到车辆插入充电枪时,与直流充电桩进行充电信息交互,若确定满足充电准备条件时,进入充电状态;接收由车载充电机发送的放电请求,根据所述放电请求执行充放电功率平衡策略,所述充放电功率平衡策略用于避免充电中断及放电中断;如此,车辆可以在边充电的同时,可对外部负载进行放电,并执行充放电功率平衡策略,避免放电中断及充电中断;提高放电效率,进而提高用户对放电功能的使用体验。
