The invention discloses an integrated type high-voltage power-on and power-off control device of an electrocar. According to the control method, the low-voltage power-on mode, the driving mode, the external charging mode, the emergency shutdown mode and the low-voltage power-off mode are included. By integrally judging the connection state of a charger, the key state and the car state, the reasonable mode is selected, so that the high-voltage power-on and power-off strategy and the charging power-on and power-off strategy in the driving process are integrated, and the problems that the current algorithm integration level is low and the operation efficiency is limited are solved. 本发明公开了种电动车集成式高压上下电控制方法，包括低压上电模式、行车模式、外部充电模式、紧急关闭模式和低压下电模式。通过综合判定充电器连接状态、钥匙状态、车辆状态，进行合理的模式选择，旨在集成行车高压上下电策略和充电上下电策略，解决当前算法集成度低、运行效率受限的问题。
