The invention discloses a data storage method, which comprises the following steps: responding to a high-voltage disconnection request, and generating a high-voltage disconnection instruction which is used for indicating disconnection of a high-voltage loop; under the first condition, the vehicle state parameters are stored for the first time; the first condition is that the high-voltage loop is disconnected and the energy storage element connected with the motor controller is not discharged. According to the method, the vehicle state parameters are stored once after high-voltage disconnection of the whole vehicle and before active discharging of the motor, the problem of unreliable storage caused by unreliable connection of the 12V storage battery can be effectively solved through the method, and meanwhile, compared with a real-time storage scheme, the service life of a storage medium can be greatly prolonged.

    本发明公开了一种数据存储方法,包括:响应高压断开请求,生成高压断开指令,所述高压断开指令用于指示高压回路断开;在第一条件下,对车辆状态参数进行第一次存储;所述第一条件为:所述高压回路断开且连接电机控制器的储能元件未放电。本发明的方法在整车高压断开之后,电机主动放电前对车辆状态参数进行一次存储,通过这样的方法可以有效避免由12V蓄电池连接不可靠带来的存储不可靠问题,同时与实时存储方案相比,可以大大提高存储介质的寿命。
