Problems solved by technology

However, if a single battery has a short-circuit fault, it will become the load of other batteries connected in parallel, and the energy of all the batteries connected in parallel will be quickly released in the faulty single battery, and the temperature of the faulty battery will rise sharply. It leaves a huge safety hazard for the normal operation of the entire battery pack, and at the same time does not understand the internal temperature of the lithium-ion battery pack, and when the lithium-ion battery is powered off or leaks, it will reduce the safety factor of the lithium-ion battery

Abstract

The invention discloses a lithium ion battery pack structure. The lithium ion battery pack structure comprises a battery pack body, a second air outlet pipe and a round air pipe, wherein a partition board is arranged in the middle in the battery pack body, a flexible package tank is arranged outside the battery pack body, and a first heat dissipation aluminum plate is arranged on the top end of the flexible package tank. The lithium ion battery pack structure specifically has an automatic protection function to lithium ions after the power is off, a certain air leakage protection function and a certain warning effect and is simple and convenient, and meanwhile, the specific fault type can be conveniently known, so that the situation that the performance of other lithium ion batteries is influenced due the continuous heat dissipation of a faulted lithium ion battery can be prevented, and furthermore, the security coefficient of the battery pack can be increased; and meanwhile, the lithium ion battery pack structure has a temperature warning effect, so that the overheated battery pack can be conveniently cooled, can be continuously cooled by virtue of heat dissipation aluminum plates, can be further cooled by virtue of a flexible water pipe and can be rapidly cooled by virtue of a draught fan.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery packs, in particular to a lithium-ion battery pack structure. Background technique [0002] Lithium-ion battery, as an energy-saving and environment-friendly power battery, represents the future direction of battery development. It is the most ideal power battery invented so far. The lithium-ion battery industry is in line with the national industrial policy and is an important development target industry in various countries. As a new energy source for automobiles, lithium-ion batteries have been widely used. However, electric vehicles have relatively high requirements on battery voltage, current, and consistency. Therefore, a battery pack composed of several lithium-ion batteries connected in series and in parallel is installed in the power box of the electric vehicle. [0003] At present, the capacity of lithium-ion battery packs is increased by connecting in parallel, which requi...
