The invention provides a charging control method and system, a vehicle and a storage medium. When the message timeout fault occurs on the charging communication link between the vehicle and the charging pile, the charging forbidding function in the vehicle is controlled to be closed, so that the charging process of the power battery can be prevented from being forbidden. The method is mainly characterized in that a message timeout fault may be caused by external electromagnetic interference, and the duration of the external electromagnetic interference may be short. Furthermore, the fast charging relay is controlled to be in the off state, the situation that too large current is conveyed to the power battery due to hysteresis of the charging pile can be avoided, and the power battery can be protected from being overcharged. And in the subsequent time, if the vehicle receives the charger identification message, the vehicle can shake hands with the charging pile again and charge again, so that the charging pile charges the power battery in the vehicle as much as possible. Therefore, the method can improve the charging probability and improve the charging experience of the user.
本申请提供控制充电的方法、系统、车辆及存储介质。在车辆与充电桩之间的充电通信链路上发生报文超时故障时,控制车辆中的禁止充电功能关闭,这能够避免动力电池的充电过程被禁止。这主要是由于报文超时故障可能由外界电磁干扰引起,外界电磁干扰的持续时长可能较短。进一步地,控制快充继电器处于断开状态,能够避免充电桩的滞后性而导致的过大电流输送至动力电池,能够保护动力电池避免过充。在随后的时间中,若车辆接收到充电机辨识报文,可重新与充电桩进行握手,并再次充电,尽最大可能地使得充电桩向车辆中的动力电池充电。因此,该方法可提高充电几率,提高用户的充电体验。
