Abstract

The invention discloses a single lithium battery pack of a new energy automobile, and belongs to the technical field of new energy automobile batteries. The single lithium battery pack of new energy automobile comprises: a single battery module. Metal frames are arranged on the left side and the right side of each single battery module, U-shaped frames are arranged at the upper end and the lower end of each single battery module in a sleeving mode, the edges of the U-shaped frames are welded to the edges of the two metal frames, and the opposite sides of the two U-shaped frames are fixedly connected through a connecting piece. According to the invention, the cooling strips are arranged between the battery panels, and the rubber water belt is arranged between the cooling strips, so that the situation that the battery panels are completely charged during charging can be inhibited, a prevention effect is achieved, and when the battery panels are swelled, cooling water in the rubber water belt overflows into the square box body, and is in contact with a super absorbent resin material arranged inside. The power-off protection device is arranged in the shell and makes contact with the super absorbent resin material arranged in the shell, power-off operation can be rapidly conducted through expansion of the super absorbent resin material, prevention and protection are synchronous, and safety is high.

Description

technical field [0001] The invention belongs to the technical field of batteries for new energy vehicles, and in particular relates to a single lithium battery pack for new energy vehicles. 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; Role. [0003] The battery overload is the most common problem in the use of batteries. It is usually caused by severe combustion caused by internal short circuits. Composition, positive and negative plates a...
