Lithium-battery phase-change-heat-management assembling structure

Abstract

The invention discloses a lithium-battery phase-change-heat-management assembling structure. The problem that as heat gathering of lithium batteries in the working process cannot be discharged in time, and the temperature gathering conditions of different parts are different, the temperature difference of the batteries is large is solved. The lithium-battery phase-change-heat-management assembling structure comprises an aluminum end plate and series copper bars, and is characterized in that all the lithium batteries are fixed through supports which are mutually parallel one by one respectively, phase-change aluminum plates are arranged on one sides of all the supports, heat generated in the charging-and-discharging process of soft-rolling cells is directly absorbed and stored by the phase-change aluminum plates, and in the temperature increasing process of the phase-change aluminum plates, absorbed heat is transmitted to the outside through the phase-change aluminum plates to reduce the temperature and the temperature clustering performance of the soft-rolling cells. The structure is stable and reliable, all the soft-rolling cells have the independent phase-change aluminum plates, temperature increasing of charging and discharging of the grouped lithium batteries is greatly reduced, and the temperature difference of the soft-rolling cells is reduced, the performance of the lithium batteries in using is improved, and the service life of the lithium batteries in using is prolonged.

Description

technical field [0001] The invention relates to lithium ion battery technology, in particular to a lithium battery phase change thermal management assembly structure. Background technique [0002] The existing lithium-ion battery market has gradually matured, and the scale of various manufacturers has also increased day by day. The advantages of lithium-ion batteries have gradually emerged, but they have also encountered great difficulties. For example, the existing grouping process of lithium batteries is fixed by the combination of components. The heat accumulation generated by the heating of lithium batteries during charging and discharging is difficult to discharge in time. Lithium batteries in different positions have different temperature accumulations, resulting in lithium batteries. The large temperature difference affects the performance and life of the lithium battery. For example, the patent publication number is CN103138029A, a heat management system for a lithi...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that in the prior art lithium battery grouping process, it is fixed by the combination of components. Although the phase change material is used, the heat accumulation of the lithium battery cannot be discharged in time during the working process, and the temperature accumulation conditions of different parts are also different. The temperature difference of the battery is large, which affects the performance and service life of the battery. This solution provides a lithium battery phase change thermal management assembly structure
