Light vehicle battery management system device

Abstract

The invention belongs to the technical field of battery management systems, and particularly relates to a light vehicle battery management system device which comprises a battery box body, a box coverand single batteries. Accommodating grooves which are uniformly distributed are formed in the battery box body; an air bag is arranged at the bottom of the accommodating groove; chutes are formed inthe front side and the rear side of the battery box body; L-shaped sliding plates are connected into the sliding grooves in a sliding mode, and first springs which are evenly distributed are fixedly connected between the side faces of the sides, away from the single batteries, of the sliding plates and the inner walls of the sliding grooves. the side space, away from the single batteries, of the sliding plate communicates with the inner space of the airbag through a first air channel; air outlets are uniformly formed in the upper surface of the battery box body; and the spaces of the sides, far away from the single batteries, of the sliding plates are communicated with the corresponding deflation openings, and control valves are arranged in the deflation openings. The device is convenientto operate, the single batteries are fixed and taken out through cooperation of the air bags and the sliding plates, and replacement of the single batteries is facilitated.

Description

technical field [0001] The invention belongs to the technical field of battery management systems, in particular to a light vehicle battery management system device. Background technique [0002] With the rapid development of social economy and science and technology, energy and environmental issues have become two major problems for human beings. Traditional fuel vehicles have large primary energy consumption, low efficiency and large pollutant emissions, which have posed a great threat to the energy and environmental fields of society. Electric vehicles have the advantages of zero primary energy consumption and zero pollutant emissions. As the heart of electric vehicles, batteries are the key to the development of the electric vehicle industry. [0003] In the manufacturing process of power batteries, due to process problems and uneven materials, there are slight differences in the thickness of battery plates, microporosity, and the degree of activation of active material...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, the entire battery pack is often fixed inside the battery box by means of welding and adhesion in the prior art, so that when a single battery is damaged, it is often necessary to replace the entire battery pack, and the battery disassembly and replacement process is complicated and difficult. , and the battery itself is easily damaged during replacement, which increases the replacement time and cost and the internal heating and cooling system in the battery continuously heats and cools the battery, resulting in increased internal friction. A light-duty vehicle battery management system device proposed by the present invention
