The invention discloses a control method of a pure electric vehicle system and a vehicle with the pure electric vehicle system. The method comprises the following steps: acquiring environment temperature information; generating a control instruction set based on the environment temperature information; based on the control instruction set, controlling a cooling oil circulation system and a cooling water circulation system in the pure electric vehicle system to execute a target heat exchange strategy, the target heat exchange strategy comprises at least one of a cooling oil loop minor circulation strategy, a cooling oil loop major circulation and cooling water loop minor circulation strategy and a cooling oil loop major circulation and cooling water loop major circulation strategy. The technical problem of battery charging and discharging power and low-temperature energy attenuation or thermal runaway risk caused by battery temperature change is solved.

    本发明公开了一种纯电动汽车系统的控制方法及具有其的车辆。其中,该方法包括:获取环境温度信息;基于环境温度信息生成控制指令集;基于控制指令集控制纯电动汽车系统中冷却油液循环系统和冷却水循环系统执行目标换热策略,其中,目标换热策略包括如下至少之一:冷却油液回路小循环策略、冷却油液回路大循环且冷却水回路小循环策略、冷却油液回路大循环且冷却水回路大循环策略。本发明解决了由于电池温度的变化造成的电池充放电功率和低温能量衰减或热失控风险的技术问题。
