The invention discloses a pure electric vehicle battery charging temperature control method, and belongs to the technical field of battery vehicle charging. The method comprises the following steps: establishing a battery heat dissipation model during charging; measuring a real-time environment temperature and a real-time charging current during charging, and substituting the real-time environmenttemperature and the real-time charging current into the model to calculate real-time temperature data of the battery; comparing the real-time temperature data of the battery with the set optimal charging temperature data of the battery, comparing the real-time charging time under the condition of the real-time charging current with the set charging time, and comprehensively controlling the charging current and the temperature control module to enable the battery to be charged under the optimal temperature data and within the set charging time. The charging current can be controlled and Whether temperature control module works or not can be controlled according to the charging time requirement set by a user, and heat dissipation of battery charging is reasonably controlled.
