Abstract

The invention discloses a power battery. The power battery is provided with a positive electrode and a negative electrode and is of a cuboid structure, the relation of length, width and height of thepower battery is in a way that the length is 0.9-1.2 times of the width, the length is 6 times of the height, the power battery also comprises a positive tab and a negative tab, the positive tab is connected with the positive electrode, the negative tab is connected with the negative electrode, the positive tab and the negative tab are respectively arranged on two opposite surfaces, with minimum areas, of the power battery, and the positive tab and the negative tab both are rectangular sheet-shaped structures with a length-width ratio being 2:1. The invention also discloses a battery thermal management system of the power battery. By optimizing a cooling structure of the battery and performing thermal management on the power battery, the cooling performance of the power battery is improved, the heat generation quantity of the power battery is reduced, and the technical problems of insufficient cooling performance of the lithium ion battery and high heat generation quantity in the priorart are solved.

Description

technical field [0001] The invention relates to the field of power vehicles, in particular to a power battery and a heat management system for the power battery. Background technique [0002] With the continuous development of modern industry, automobiles have become a product that can be seen everywhere in life, and the increasing number of automobiles has brought various problems, such as environmental pollution, energy crisis, etc., so new energy vehicles have been launched one after another. At present, new energy vehicles mainly include hybrid electric vehicles, pure electric vehicles and fuel cell electric vehicles. Because new energy vehicles are more energy-efficient, their energy sources are cleaner, and their energy sources are more diversified, the promotion of new energy vehicles is a solution to the current situation. It is an effective solution to many problems caused by too many cars, but in the current promotion process, one of the main problems restricting t...
