The invention relates to an on-gear protection strategy scheme for a truck lithium battery system, which comprises the following steps of: 1, judging whether an on-gear protection mode is entered or not, if so, waiting to exit, and otherwise, judging whether the on-gear protection mode is entered or not; if not, judging whether a protection-on-file detection mechanism is triggered or not, and if the detection mechanism is triggered, detecting and judging whether protection-on-file needs to be executed or not; according to the method, the safety is high, and in the gear-carrying state, the battery system can bear an overlarge current load during starting, so that the battery is damaged or the service life of the battery is shortened. By disconnecting the output circuit and waiting for a period of time to confirm the state, the strategy effectively avoids the risk of overload of the battery system, prolongs the service life of the battery, improves the starting safety of the truck, and protects a driver and the surrounding environment from being influenced by the displacement risk.

    本发明涉及一种针对卡车锂电池系统带档保护策略方案,包括以下步骤:步骤一:判断是否已经进入了带档保护模式,是则等待退出,否则判断是否进入;没有则去判断是否触发了带档保护检测机制,若触发了检测机制再进行检测判断是否需要执行带档保护;若是已经进行带档保护则进行保护退出策略,本发明安全性高,在带档状态下,启动时可能会导致电池系统承受过大的电流负载,从而造成电池损坏或电池寿命缩短。通过断开输出电路,并等待一段时间来确认状态,该策略有效避免了电池系统过载的风险,延长了电池的使用寿命,提高卡车启动的安全性,保护驾驶员和周围环境不受位移风险的影响。
