Problems solved by technology

[0007] (1) The technical problem of deflagration or even explosion after the battery casing is damaged is not considered at the same time
[0008] (2) Its heat dissipation is only carried out through the circulating water pipeline inside the cell matrix. When the circulating water pipeline fails to circulate due to failure, the risk of battery heat treatment is very high
[0009] (3) Its heat dissipation is only carried out through the circulating water pipeline inside the cell matrix. The circulating water pipeline is relatively dense, and it is relatively easy to cause internal short circuit caused by water cooling liquid leakage, causing vehicle failure
[0013] (1) Its explosion-proof is equipped with a closed cover and an exhaust device, which will discharge combustible gases such as hydrogen gas during the charging and discharging process of the battery, which enhances its safety performance. deflagration or even explosion
[0014] (2) Its design also only dissipates heat through the water-cooling cycle. When the circulating water pipe fails to circulate due to failure, the risk of battery heat treatment is very high

Embodiment Construction

[0066] Below in conjunction with embodiment, further illustrate the present invention.

[0067] see figure 1 , figure 2 , image 3 , Figure 4 It can be known that a battery box for an electric vehicle according to the present invention has a shell structure, and a heat exchange area 2 and a battery installation area 1 are arranged in the shell of the battery box. The heat exchange areas 2 are arranged at intervals, and the heat exchange area 2 The two ends of the battery box are connected to the side wall of the battery box. The interval between the heat exchange area 2 and the heat exchange area 2 is the battery installation area 1. The heat exchange area 2 is provided with heat dissipation units 4 arranged at intervals. The interval between heat pipes and cold pipe installation areas 5, heat dissipation unit 4 is provided with heat dissipation chambers 6 adjacent to each other, heat pipes, cold pipe installation areas 5 still have gaps after installing heat pipes 10 and...

Abstract

The invention discloses a battery box of an electric vehicle and a heat dissipating and heating system and method thereof. A heat exchanging area and a battery installation area are arranged in a housing of the battery box, heat dissipating units are arranged in the heat exchange area at intervals, the spacing between each heating dissipating unit is a hot and cold tube installation area, the heating dissipating unit is provided with a heat dissipating cavity, hot and cold tubes are installed in the hot and cold tube installation area, and the cold tubes are communicated with a water tank toform a circulation loop of cooling liquid; spacing is reserved between each battery pack in the battery installation area, a heat guiding plate is arranged in the spacing, the hot and cold tubes are welded to the heat guiding plate through brazing, and crumple holes are formed in the area where the side walls of the battery box is connected with the heat exchange area at intervals. According to the heat dissipating and heating system and method, different heat exchanging modes are arranged, the deflagration probability of the battery after the vehicle is collided is reduced, and heat management of the battery box is improved to better meet different demands of the heat management of different seasons.

Description

technical field [0001] The present invention relates to, more precisely, an electric vehicle battery box and its cooling and heating system and method. Background technique [0002] With the development of the economy, people are becoming more and more aware of the importance of the environment. Governments of various countries have vigorously promoted new energy vehicles to reduce the damage to the earth caused by people's living activities. Electric vehicles are the main development direction of new energy vehicles. The core technologies of electric vehicles include batteries, motors and electronic controls. At present, the wooden barrel effect of the battery restricts the development of electric vehicles. Nowadays, many automobile manufacturers mostly use lithium-ion batteries as power batteries in order to improve the cruising range of vehicles. First of all, lithium-ion batteries have the advantages of high voltage (3.7V), no memory effect, fast charging speed, high sp...
