Insulating safe battery module

Abstract

The invention relates to a secondary electric power supply and especially relates to an insulating safe battery module. The insulating safe battery module is characterized in that the insulating safe battery module comprises an insulating base and an insulating top cover; longitudinal grooves of which the number is the same as the number of unit batteries are arranged at an upper part of the insulating base side by side; the insulating top cover comprises an insulating frame and an insulating cover plate; the insulating frame is provided with longitudinal caulking grooves side by side so that the insulating frame can be sleeved on the unit batteries and electrodes are shown upward; and the insulating cover plate covers the insulating frame and is connected to the insulating frame. The insulating safe battery module has the advantages that 1, the insulating base and the insulating top cover in the insulating safe battery module form an integral body so that use and maintenance is convenient and operation is simple; 2, an insulating division plate is arranged between each adjacent two of the grooves or the caulking grooves so that safety is high; and 3, in the insulating safe battery module, a ventilated gap is arranged between each adjacent two of unit batteries so that battery heat dissipation is promoted; a temperature difference between unit batteries is reduced; a battery service life is prolonged; and use performances are guaranteed.

Description

technical field [0001] The invention relates to a secondary power supply, in particular to an insulation safety battery module. Background technique [0002] In the existing technology, facing many problems such as serious environmental pollution, depletion of oil resources, and climate warming, the research and development of energy storage technology has attracted more and more attention from the energy, transportation, and electric power departments of various countries. As a key component of energy storage, batteries directly affect the performance of energy storage systems. Due to the large number of batteries required by the energy storage system, several single batteries are usually used to form a battery module, and then a large energy storage system is formed by combining multiple battery modules. Limited by space, the batteries in the energy storage system need to be closely arranged and connected, and their electrodes are densely arranged together. Therefore, whe...

AI Technical Summary

Problems solved by technology

Limited by space, the batteries in the energy storage system need to be closely arranged and connected, and their electrodes are densely arranged together. Therefore, when installing and connecting the batteries, it is easy to be misconnected, and because the distance between the battery electrodes is too close, the operation It is easy to short circuit when operating one of the electrodes, and it is easy to touch the adjacent battery electrode when operating one of the electrodes, causing electric shock to the human body; in addition, all the electrodes and the connections between the electrodes are exposed, so the above-mentioned battery module has potential safety hazards question

[0003] In addition, when the closely arranged battery cells are charged and discharged at different rates, the battery will generate a large amount of heat at different heat generation rates, and the accumulation of time and the influence of space will produce uneven heat accumulation, which will lead to a decrease in the operating environment temperature of the battery pack. complex and changeable

Due to the dense arrangement of a large number of batteries, the middle area will inevitably accumulate more heat, while the edge will be less, resulting in a large temperature difference between the single cells of the battery pack, and exacerbating the inconsistency of the internal resistance and capacity of the batteries.

If it accumulates for a long time, it will cause some batteries to overcharge and overdischarge, which will affect the life and performance of the battery and cause safety hazards
