Problems solved by technology

However, the module adopts a fixed restraint method, which has poor cushioning ability when under stress. After the battery ages and expands, the pressure on the battery surface will increase, which will accelerate the decay of battery life and easily lead to restraint failure and module failure. damage to

Abstract

The present disclosure provides a heat management and pressure management system for electric vehicle power batteries. The present disclosure can perform heat management and pressure management on the electric vehicle power batteries at the same time. On the basis of realizing the cooling and heating functions, the distance between each battery cell can be reduced. The temperature difference between the battery packs can prevent the thermal diffusion between the battery packs, and the elastic body and the baffle are used to restrain and limit the power battery pack, and at the same time, a certain pressure is applied to the battery to prolong its service life, and the power battery pack is set in the place Between the liquid cold plate and the inner wall of the accommodating cavity, each power battery can be in contact with the liquid cold plate, ensuring effective heat dissipation for the power battery, and further improving the life of the battery; the present disclosure reduces the number of parts and improves The energy density of the battery pack and the reliability of the system are improved, and the mass production cost is reduced.

Description

technical field [0001] The disclosure belongs to the technical field of electric vehicle power battery management, and specifically relates to an electric vehicle power battery thermal management and pressure management system, and more specifically, relates to an electric vehicle power battery box, a management system, a method, and an electric vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Compared with traditional fuel vehicles, electric vehicles have more advantages in environmental protection and energy utilization. Power batteries are the main source of power for electric vehicles. On the one hand, during the process of charging and discharging, the battery will generate a lot of heat, and the accumulation of heat in the limited space of the power battery pack will cause a severe temperature rise, and the inconsistent hea...
