X) which is used for solving the problem that the discharge current of the battery is reduced under the low temperature, and comprises a box body, a cover body, a plurality of battery modules, a microwave heating device, a switch device and a temperature sensor, wherein the cover body can be in sealing fit with the box body and encloses an in-box space; whether switching device is connected with temperature sensor and according to the temperature control microwave heating device of temperature sensor feedback start heating function, when the temperature of temperature sensor feedback is less than first settlement temperature, switching device control microwave heating device start heating function, when the temperature of temperature sensor feedback is greater than the second settlement temperature, switching device control microwave heating device closes heating function, this technical scheme adopts microwave heating device to come to heat the battery module, the battery module is close to microwave heating device one side and keeps away from microwave heating device one side heating degree and differs, lead to the battery module overheated easily, therefore if improve on this technical scheme's basis, research and development a new construction battery box that can the even heating battery module will have positive meaning.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a battery box to solve the problem mentioned in the background art.

In order to achieve the above purpose, the utility model provides a following technical scheme: comprises a box body, a battery module, a heat conducting oil layer and a control module, the top surface of the box body is provided with 2 joints, the battery module is arranged in the box body and is electrically connected with the joints, the heat conducting oil layer is filled in the box body, the control module is arranged on the surface of the box body in an embedded manner, the control module is electrically connected with the battery module, the control module also comprises a first temperature sensor, a second temperature sensor and a heating module, the first temperature sensor is arranged on the outer surface of the box body in an embedded manner, the second temperature sensor and the heating module are both arranged in the box body, the first temperature sensor, the second temperature sensor and the heating module are all connected with and controlled by the control module.

Preferably, the heat-conducting oil layer is a dimethyl silicone oil heat-conducting layer.

Preferably, the control module is a PLC controller.

Preferably, the heating module is a resistance wire.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

the utility model provides a pair of battery box, first temperature sensor responds to the box external temperature and transmits temperature information to control module, second temperature sensor responds to the temperature of the interior heat conduction oil layer of box and transmits temperature information to control module, when first temperature sensor senses that the box external temperature is less than the external temperature default, control module starts heating module, and heating module heats the heat conduction oil layer, because the heat conduction oil layer does not have the ion of free movement and consequently can not electrically conduct, the heat conduction oil layer can heat the battery module evenly, fully; when the second temperature sensor senses that the temperature of the heat-conducting oil layer in the box body is higher than the preset temperature value of the heat-conducting oil layer, the control module closes the heating module.

The utility model discloses simple structure, reasonable in design has practical meaning and spreading value, expects to produce good economic benefits.
