The invention provides an electric vehicle data monitoring method and an electric vehicle, and relates to the technical field of electric vehicle data monitoring. The electric vehicle data monitoring method is applied to a VCU of an electric vehicle, the electric vehicle further comprises a BMS, a Tbox and a low-voltage storage battery, after high-voltage connection of the electric vehicle is disconnected, the low-voltage storage battery is controlled to supply power to the VCU, the BMS and the Tbox, and timing is started; and then a wake-up instruction is sent to the BMS and the Tbox, so that the BMS collects power battery data, the power battery data is sent to the cloud platform through the Tbox, and sending of the wake-up instruction is stopped when the preset duration is reached or high-voltage reconnection of the electric vehicle is achieved. The electric vehicle data monitoring method and the electric vehicle provided by the invention have the advantage that the data can be ensured to be complete and continuous even if the spontaneous combustion accident of the power battery occurs.

    本申请提供了一种电动汽车数据监控方法与电动汽车,涉及电动汽车数据监控技术领域。该电动汽车数据监控方法应用应用于电动汽车的VCU,电动汽车还包括BMS、Tbox以及低压蓄电池,当电动汽车的高压连接断开后,控制低压蓄电池为VCU、BMS以及Tbox供电,并开始计时;然后向BMS与Tbox发送唤醒指令,以使BMS采集动力电池数据,并通过Tbox将动力电池数据发送至云平台,并在达到预设时长或电动汽车的高压重新连接时,停止发送唤醒指令。本申请提供的电动汽车数据监控方法与电动汽车具有即使出现动力电池自燃事故,也能够保证数据是完整的、持续的优点。
