The invention discloses a monitoring method of a battery high-voltage system and a vehicle. The method comprises the following steps: acquiring an operation state of a preset voltage sampling module and a plurality of relay identifiers of a plurality of relays in a battery high-voltage system; in response to normal operation of the preset voltage sampling module, performing voltage sampling on the plurality of relays based on the preset voltage sampling module and the plurality of relay identifiers to obtain a plurality of relay voltages; based on the plurality of relay voltages and a battery total voltage of the battery high-voltage system, determining a plurality of operation states of the plurality of relays, the battery total voltage being a voltage obtained by converting the relay voltages according to a loop voltage division rule; and outputting a system state of the battery high-voltage system based on the plurality of operation states. According to the invention, the technical problem of low monitoring accuracy of the battery high-voltage system in the prior art is solved.

    本发明公开了一种电池高压系统的监控方法和车辆。其中,该方法包括:获取预设电压采样模块的运行状态,以及电池高压系统中多个继电器的多个继电器标识;响应于预设电压采样模块运行正常,基于预设电压采样模块和多个继电器标识,对多个继电器进行电压采样,得到多个继电器电压;基于多个继电器电压和电池高压系统的电池总电压,确定多个继电器的多个运行状态,其中,电池总电压是根据回路电压分压规则,对继电器电压进行转换得到的电压;基于多个运行状态输出电池高压系统的系统状态。本发明解决了相关技术中对电池高压系统的监控准确度低的技术问题。
