Battery box with fast heat dissipation

Abstract

The invention discloses a battery box with a rapid heat dissipation function, which includes a box body with an open upper end and a cover plate hingedly matched with it, and a T-shaped blind hole is opened in the side wall of one end of the box body, and a T-shaped blind hole is slidably arranged in the T-shaped blind hole. The matching slider and the cover plate are composed of a support section and a snap-in section. One end of the support section is hinged to the slider and the other end is hinged to one end of the snap-in section. The other end of the snap-in section passes through an elastic connector The buckle is installed, and the side wall of the box body is provided with a slot matching the buckle. The battery pack is fixed in the box body, and a balancing system is installed on the battery pack. When part of the support section enters the T-shaped blind hole until the slider contacts the bottom of the T-shaped blind hole, the clamping section hinged to the end of the support section changes from a horizontal position to a vertical position. That is, the bottom surfaces of the supporting section and the clamping section are in contact with each other. At this time, the normal connection between the cover plate and the box body is ensured, and at the same time, the best viewing angle can be improved for the operator.

Description

technical field [0001] The invention relates to a battery pack of an electric vehicle, in particular to a battery box with a rapid heat dissipation function. Background technique [0002] In order to protect the environment, energy conservation and environmental protection and the promotion and application of green energy have emerged in response to the situation. One of the ways to protect the environment is to expand the use of electric vehicles and reduce the use of fuel-efficient vehicles, but now electric vehicles have been in a downturn , The main bottleneck restricting the development of electric vehicles is the life of power batteries. Generally speaking, the battery box of an electric car needs 75 lithium-ion batteries in series to supply power to reach 200AH / 300V. Each lithium-ion battery is connected in series to form a battery pack. Because the aging degree of each lithium-ion battery in the battery pack is very different , in the process of charging the battery...

Problems solved by technology

However, after the battery box is loaded with a battery pack, the space between the battery pack and the upper cover of the battery box is small, and the existing equalization system is generally large in size and cannot be placed inside the battery box. Therefore, the existing equalization system is generally placed in the battery box The exterior takes up a lot of space outside the car. Under the premise that the space of the car is so compact, the market is eager to place the equalization system inside the battery box without changing the size of the original battery box, so as to save the space of the car.
