A lithium battery thermal management control device

Abstract

The invention discloses a lithium battery thermal management control device, which includes a first lithium battery assembly case component and a second lithium battery assembly case component, and the structure of the second lithium battery assembly case component in the present invention is consistent with that of the first lithium battery assembly case component A set of lithium battery thermal management assembly shell structures is formed between the first lithium battery assembly shell assembly and the second lithium battery assembly shell assembly. When multiple sets of lithium batteries are assembled side by side, the multiple sets of lithium battery thermal management assembly shell structures are fixed side by side. By tightening the tension spring, a housing with a variable spacing between the first lithium battery assembly shell assembly and the second lithium battery assembly shell assembly is formed, and the X-shaped guiding telescopic plate is used to ensure that the first lithium battery assembly shell Stability and reliability when adjusting the distance between the component and the second lithium battery assembly shell component, when multiple battery cells are integrated into a battery pack, multiple battery cells are folded and clamped in multiple sets of lithium battery thermal management assembly shells In the structure, the integration of multiple battery cells is realized.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, and in particular relates to a thermal management control device for a lithium battery. Background technique [0002] The battery pack of an electric vehicle is composed of multiple single cells. However, there are certain differences between the single cells. As the use time increases and the number of charge and discharge increases, the differences between the single cells will become more and more big. [0003] The existing technology has the following problems: according to the power demand of the vehicle, it is necessary to integrate a plurality of battery cells into a battery pack, and the battery with the backward performance in the single cell will become more prominent, thereby affecting the performance of the entire battery pack. A single battery with seriously backward performance needs to be replaced in time to ensure that the entire battery pack can be used normally. At th...

Problems solved by technology

[0003] The existing technology has the following problems: According to the power demand of the vehicle, multiple battery cells need to be integrated into a battery pack, and the batteries with poor performance in the single cells will become more prominent, thereby affecting the performance of the entire battery pack. Single batteries with seriously backward performance need to be replaced in time to ensure that the entire battery pack can be used normally. At the same time, the temperature of the entire battery pack will rise after a single lithium battery heats up, which will affect the performance of other lithium batteries. The battery cells are integrated into the installation structure of the battery pack, and the independent heat dissipation structure that facilitates the thermal management of multiple battery cells is not conducive to the integration of multiple battery cells
