Embodiment Construction

[0032] In order to make the purpose, technical solutions and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the protection scope of the present invention.

[0033] The invention provides a novel lithium-ion power battery module design method, which is applied to an aluminum shell square battery module,

[0034] Insulating gaskets are arranged between the battery cells, and the battery cells are sealed and connected to the insulating gaskets;

[0035] Such as figure 1 As shown, the battery cells should be kept in close contact as far as possible, that is, no gaps are reserved between the battery cells except for the necessary insulating gaskets. Using this arrangement, the battery cells will be damaged during use. The volume e...

Abstract

The invention discloses a novel lithium ion power battery module design method and a battery module, which are applied to an aluminum shell square battery module. By designing and developing the battery module according to the method, the gravimetric specific energy and volumetric specific energy of the battery module can be increased remarkably under the condition of constant energy density of a battery monomer, thereby remarkably increasing the overall energy density of a battery system. The method is of great significance to the development of the electric vehicles. Moreover, the battery module developed according to the method has high assembly performance and interchangeability, the assembly performance of the battery system is improved, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery manufacturing, in particular to a novel lithium-ion power battery module design method and the battery module. Background technique [0002] The lithium-ion power battery module is the core component of the power battery system of pure electric and hybrid vehicles. Its design is directly related to and affects the performance and life of the entire battery system, and the performance of the power battery system is related to electric vehicles. overall performance. Therefore, the design of power battery modules has become an important part of the development of electric vehicles. [0003] Lithium-ion power battery monomers currently on the market can usually be divided into aluminum shell square batteries, polymer flexible packaging batteries and circular batteries. Lithium-ion batteries have been used in a very wide range of fields. Due to their high energy density and performance St...
