Battery box with fast heat dissipation function

Abstract

The invention discloses a battery box with a fast heat dissipation function. The battery box comprises a box body and a cover board, wherein the upper end of the box body is open; the cover board is in articulated fit with the box body; a T-shaped blind hole is formed in the side wall of one end of the box body; a slide block which is in fit with the T-shaped blind hole is arranged in the T-shaped blind hole in a sliding manner; the cover board comprises a support segment and a clamping segment; one end of the support segment is articulated with the slide block; the other end of the support segment is articulated with one end of the clamping segment; a buckle is arranged at the end part of the other end of the clamping segment through an elastic connector; a clamping groove which is in fit with the buckle is formed in the side wall of the box body; and a battery pack is fixed in the box body and is provided with an equalization system. When the support segment locally enters the T-shaped blind hole until the slide block contacts the bottom of the T-shaped blind hole while the clamping segment which is articulated with the end part of the support segment is converted into a vertical placement position from a horizontal placement position, the bottom surfaces of the support segment and the clamping segment contact each other, so that normal connection of the cover board and the box body is ensured; and meanwhile, the best perspective of observation can also be improved for an 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.
