New energy automobile battery assembly based on independent isolation and having detonation prevention function

Abstract

The invention relates to the technical field of new energy batteries, and discloses a new energy automobile battery assembly based on independent isolation and having detonation prevention function. The new energy automobile battery assembly comprises a cold supply device and a battery assembly, wherein the cold supply device is communicated with the heat dissipation groove of the battery assemblythrough a square pipe. According to the invention, by improving the transverse groove and the annular groove, the transverse groove and the annular groove are filled with liquid water, so that the area where each dry battery is located can be cooled, and the temperature of each dry battery can be controlled within an effective range when the dry battery is used so as to ensure the use safety of the battery; and by using the cold supply device, when the temperature in the battery layering fixing device is relatively high, the cold supply device can transmit cold air into the transverse grooveand the annular groove, so that the water temperature in the annular groove and the transverse groove is reduced, and the temperature of the battery can be rapidly controlled when the battery is at ahigh temperature so as to further improve the safety of the dry battery.

Description

technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a battery assembly for new energy vehicles based on separate isolation and anti-deflagration. Background technique [0002] There are slight differences with different types of new energy vehicles. In a pure new energy vehicle that is only equipped with a battery, the battery is the only power source for the vehicle's drive system. In a hybrid vehicle equipped with a traditional engine (or fuel cell) and battery, the battery can not only play the role of the main power source of the vehicle drive system, but also act as an auxiliary power source. It can be seen that at low speed and starting, the battery plays the role of the main power source of the vehicle drive system; when accelerating at full load, it plays the role of an auxiliary power source; Role.

AI Technical Summary

Problems solved by technology

[0003] The existing car batteries are multiple single-chip batteries connected in series, usually with about 96 battery packs. The risk of such an installation is very high, because when a single battery poses a safety hazard, the entire battery mechanism will be destroyed in just a few seconds. In the case of deflagration, when the vehicle is in danger of deflagration, the driver generally has no chance to escape, and when the batteries of large modules are connected in series, when a single battery is heated, it will be quickly transferred between the battery packs. In this way, the temperature increases block , high risk
