The invention discloses a range extender automobile control method, which belongs to the technical field of automobile control, and comprises the following steps of: carrying a BMS (Battery Management System) on a whole automobile to monitor the state of a power battery of the automobile in real time; trial start: trying to start the automobile through a start button of the automobile; when the power battery of the vehicle is in power-lack protection, the range extender uses a 12V low-voltage system to start a motor to start an engine so as to drive a generator to operate, the output voltage of the generator is set to be the current voltage value V1 of the power battery, and the output voltage is a progressive increase curve; the rising time of 0-V1 voltage needs to be set to meet the pre-charging requirement of the whole vehicle battery, when the temperature of the battery cell exceeds the use range, the solution strategy is adopted, meanwhile, the battery cell can be heated through the PTC to reach the normal use temperature range, and therefore the battery cell can be used normally. The problem that the whole vehicle cannot be started to run when the power battery of the extended-range vehicle is lack of electricity or the environment temperature exceeds the use range of the power battery is solved.
本发明公开了一种增程器汽车控制方法,属于汽车控制技术领域,包括整车搭载BMS电池管理系统,对汽车的动力电池状态进行实时监控;试启动,通过汽车的启动按键尝试启动汽车;本发明在车辆出现动力电池亏电保护时,增程器使用12V低压系统启动马达将发动机启动,从而带动发电机运转,并设置发电机的输出电压为动力电池当前电压值V1,且输出电压为递增曲线,0‑V1电压的上升时间需要以满足整车电池预充要求进行设定,在电池电芯温度超过使用范围时,采用上述解决策略的同时,可以通过PTC对电池电芯加热使其达到正常使用的温度范围,解决了增程式汽车在动力电池亏电或环境温度超过动力电池使用范围时,整车无法启动行驶的问题。
