Novel battery pack structure

Abstract

A novel battery pack structure comprises an upper pole plate, a lower pole plate, a battery holder, a power management device, a heat management device and single batteries, the battery holder comprises a base body, isolation walls arranged in the base body and a plurality of spaced mounting chambers formed by the isolation walls, and the single batteries are arranged in the mounting chambers; theupper pole plate and the lower pole plate are detachably fixedly connected to the upper side and the lower side of the battery holder, the upper pole plate and the lower pole plate are provided withpole pieces, and the pole pieces are serially connected with the single batteries; the power management device is fixedly connected to the battery holder and is connected with every single battery; and the heat management device includes heat conducting plates embedded in the isolation walls and a heat recovery device connected with the heat conducting plates. The novel battery pack structure hasthe advantages of simple structure, good battery monitoring effect, good temperature regulation effect, energy saving, emission reduction and strong use flexibility.

Description

technical field [0001] The invention relates to the technical field of battery pack packaging structures, in particular to a novel battery pack structure. Background technique [0002] my country's cities are characterized by dense population and large urban scale. In this case, electric bicycles have been widely used as a means of transportation with convenient driving and long mileage. [0003] Electric vehicle power batteries generally include traditional lead-acid batteries and new graphene-based lithium batteries. Traditional lead-acid batteries have problems of slow charging, heavy weight, and certain environmental pollution; graphene-based lithium batteries have the characteristics of fast charging. , but its fast charging is accompanied by rapid heat generation, especially for a battery pack in which multiple battery cells are connected in series or in parallel, the heat is generated faster and less likely to dissipate. Excessive storage temperature will inevitably ...

AI Technical Summary

Problems solved by technology

It uses micro-channels to cool the battery. The cooling efficiency of micro-channels is low, and it does not have the function of low temperature insulation.

[0005] At the same time, in the battery pack assembly form in which multiple battery cells are connected in series, once one of them is damaged or fails, it will affect the performance of the entire battery pack.
