The invention discloses a heat preservation device for a battery in an electric vehicle. The structure of the heat preservation device comprises an adjustment knob, a battery assembly machine body, acooling fan, a power connector, a wiring protection ring, a power transmission ring, an air hole protection cover, wherein the battery assembly machine body is a long cuboid, the cooling fan is lockedwith a front side of a right end, the power connector is locked with a rear side of the right end, the power connector is a cuboid, the wiring protection ring is vertically glued with a middle part of the right end, the power transmission line penetrates through a middle part of the wiring protection ring and is locked with the power connector and is in transition matching with the wiring protection ring, the air hole protection cover is in a round shape and is embedded to and locked with a middle part of a right end of the cooling fan, and the adjustment knob is a cylinder. Automatic low-temperature detection, warming heat preservation, automatic rated over-temperature detection and decompression cooling of the device can be achieved by a mechanism comprising a baffle plate, a spring, apull rope, a gear and the like when a user uses the device; and moreover, trigger pressure adjustment of low-temperature detection and over-temperature detection also can be performed by the device, so that the device is higher in assembly safety and is more convenient to use.
Description
technical field [0001] The invention relates to a heat preservation device for batteries in electric vehicles, belonging to the field of heat preservation devices for automobile batteries. Background technique [0002] When the battery is used in the season of severe cold and low temperature, it must be heated to ensure the normal operation of the battery, and at the same time ensure the normal start and operation of the vehicle. Batteries generate the most heat at low temperatures. As a result, when the vehicle is started in severe cold weather, most of the energy generated by the battery pack will be used for heat generation instead of generating current for vehicle operation. If starting at low temperature will cause the current in the battery pack to be unstable, and it will also affect the life of the battery. In order to ensure the normal and effective operation of the battery, the battery pack must be heated at a low temperature. And this kind of device used to kee...
