The invention discloses a power battery charging method of an extended-range fire fighting truck and the extended-range fire fighting truck in the technical field of special vehicles, and the charging method comprises the following steps: in response to completion of insertion of the extended-range fire fighting truck and a charging gun of a charging pile, the charging pile wakes up a power battery controller, and the power battery controller wakes up a vehicle control unit and enters a standby state; in response to a quick charging instruction sent by the vehicle-mounted large screen and a charging request instruction sent by the power battery controller received by the vehicle control unit, the vehicle control unit sends a charging permission instruction to the power battery controller and the range extender controller; in response to a charging parameter instruction and a charging pile performance parameter which are sent by a power battery controller and received by a vehicle control unit, the vehicle control unit calculates the output power of a range extender, generates a range extender control instruction and sends the range extender control instruction to a range extender controller, and the range-extended fire fighting truck enters a quick charging state; the charging pile and the range extender can be charged at the same time, the charging time is shortened, and the airport use requirement is met.

    本发明公开了特种车辆技术领域的一种增程式消防车的动力电池充电方法及增程式消防车,充电方法包括:响应于增程式消防车与充电桩的充电枪插接完成,充电桩唤醒动力电池控制器,动力电池控制器唤醒整车控制器并进入待命状态;响应于整车控制器接收到车载大屏发送的快速充电指令和动力电池控制器发送的请求充电指令,整车控制器向动力电池控制器和增程器控制器发送充电允许指令;响应于整车控制器接收到动力电池控制器发送的充电参数指令和充电桩性能参数,整车控制器计算增程器输出功率,并生成增程器控制指令发送至增程器控制器,增程式消防车进入快速充电状态;本发明能够实现充电桩和增程器同时充电,缩短充电时间,满足机场使用需要。
