The invention belongs to the technical field of new energy vehicles, and particularly relates to a charging temperature control system and method, an electric vehicle and a charging pile. The charging temperature control system comprises a battery pack arranged on the vehicle, an outer circulation temperature control pipe system and a vehicle controller; the external circulation temperature control pipe system is configured to be capable of exchanging heat with the battery pack, and the external circulation temperature control pipe system comprises a first liquid inlet and a first liquid outlet; the vehicle controller is used for obtaining the state information of the battery pack and sending a temperature control request to the charging pile. According to the charging temperature control system, the charging pile can be used for controlling the temperature of the battery pack of the vehicle, the charging pile can start the temperature adjusting device in advance before the vehicle arrives, the heat-conducting medium is adjusted to the proper temperature range in advance, and therefore after the vehicle is in butt joint with the charging pile, the temperature of the battery pack is adjusted. The heat-conducting medium in the charging pile can quickly heat or cool the vehicle battery pack, so that the battery pack can quickly reach a proper charging temperature, and the charging efficiency is improved.

    本发明属于新能源汽车技术领域,具体涉及一种充电控温系统、方法、电动汽车及充电桩,充电控温系统包括车辆上设置的电池包、外循环控温管系和车辆控制器;所述外循环控温管系被配置为能够与所述电池包进行热交换,所述外循环控温管系包括第一进液口和第一出液口;所述车辆控制器用于获取所述电池包的状态信息,并向所述充电桩发送控温请求。本发明提供的充电控温系统能够利用充电桩对车辆的电池包进行控温,充电桩能够在车辆到达前能够提前开启调温装置,将导热介质预先调整到合适的温度范围,从而当车辆与充电桩对接后,充电桩内的导热介质能够快速的对车辆电池包进行加热或冷却,以使电池包更快的达到合适的充电温度,提高充电效率。
