Problems solved by technology

For example, the existing grouping process of lithium batteries is fixed by the combination of components. It is difficult to discharge the heat generated by lithium batteries during charging and discharging. The temperature difference is very large, which affects the performance and life of the lithium battery
Especially for lithium battery packs for bicycles, manufacturers usually think that the battery pack is not big, ignoring the thermal balance of the battery pack, and the life of the battery pack is reduced due to temperature imbalance and high temperature.

Abstract

The invention relates to an assembly structure for management of transformation heat of a bicycle lithium battery, which comprises two pairs of plastic supports of which inner surfaces are correspond to each other, a plurality of battery cells which are roughly parallel to each other and clamped between the two plastic supports, and a plurality of transformation heat conducting columns which are inserted in gaps of adjacent battery cells. In the scheme of the invention, heat generated by the charging and discharging process of the battery cells is directly absorbed and stored by the transformation heat conducting columns; heat absorbed by the transformation heat conducting columns is transmitted to the external environment in the process of temperature rising of the transformation heat conducting columns, so that the temperature of the battery cells and the possibility of temperature aggregation inside a battery pack are both reduced.

Description

technical field [0001] The invention relates to a lithium ion battery technology, in particular to a phase change thermal management assembly structure of a bicycle lithium battery. 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. Especially for lithium battery packs for bicycles, manufacturers usually think th...
