The invention provides a charging pile, electric equipment, a charging system and a heating method of a battery pack, which can be applied to a new energy automobile. The charging pile comprises a power unit and a charging gun, wherein the charging gun is used for connecting the power unit and electric equipment; the charging pile is used for receiving a first message from the electric equipment, wherein the first message carries a first current value required for heating a battery pack of the electric equipment; controlling the power unit to charge and discharge with the battery pack based on the first current value; wherein a second current value output when the power unit heats the battery pack is not higher than the first current value. Based on the scheme, the current can be controlled to repeatedly flow into and out of the battery pack. As the battery pack has internal resistance, heat is generated when current flows into and out of the battery pack, and the heat can heat the battery pack to reach the temperature suitable for working. And the battery pack is heated by means of the charging pile, and the structure of the electric equipment does not need to be changed, so that the cost is saved.

    本申请提供了一种充电桩、电动设备、充电系统及电池包的加热方法,可应用于新能源汽车。该充电桩包括功率单元和充电枪,充电枪用于连接功率单元和电动设备;该充电桩用于:接收来自电动设备的第一消息,第一消息携带加热电动设备的电池包所需的第一电流值;控制功率单元基于第一电流值,与电池包之间进行充电和放电;其中,功率单元加热电池包时所输出的第二电流值不高于第一电流值。基于上述方案,可以控制电流反复地流入与流出电池包。由于电池包有内阻,电流在流入与流出电池包时会有热量产生,而这些热量可以将其加热,使其达到适宜工作的温度。且借助于充电桩对电池包进行加热,而无需对电动设备本身的结构做出改动,节约成本。
