Abstract
The utility model discloses a power battery temperature control structure which comprises a battery box and battery packs. Each battery pack comprises single batteries. Single battery air channels and gap air channels among the battery box and the battery packs are mutually communicated to form a battery box internal air channel. The power battery temperature control structure is characterized by further comprising an insulating layer, a heating layer, an air inlet pipe and an air outlet pipe. The insulating layer is pasted on the surface of the battery box, the heating layer is pasted on the insulating layer, the air inlet pipe and the air outlet pipe are installed on the battery box to be communicated with the battery box internal air channel, and the outer ends of the air inlet pipe and the air outlet pipe are connected with a ventilation system. At low temperature, ventilation is stopped, the internal temperature of the battery box is lower than a critical value, and the heating layer is powered on to work. The insulating layer enables the internal heat not to be lost. At high temperature, the heating layer does not work, the insulating layer prevents the external heat from coming inside, the external ventilation system supplies air to the inside of the air inlet pipe, and the air takes away battery heat after circulation inside the battery packs and is blown out from the air outlet pipe so as to cool the battery and prevent the battery from being too hot.
