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.
