Power type battery pack module and battery intelligent management system of electric automobile

Abstract

The invention relates to a power type battery pack module and a battery intelligent management system of an electric automobile, wherein the power type battery pack module has the advantages that the battery replacement is fast, the maintenance of a battery management system is simple, and the power type battery pack module can be fast mounted or dismounted. The power type battery pack module comprises a plurality of charging and discharging batteries installed in the battery pack module; the battery pack module is plug and play and is arranged in a battery box arranged on the electric automobile in an inserting and buckling type dismountable structure; a charging and discharging terminal and a data communication port connected with a vehicle-mounted intelligent control unit are arranged on a casing; the battery pack module is also provided with a temperature lowering mechanism and an intelligent control circuit used for controlling the charging and discharging terminal to be connected or disconnected with the outside. The problems of too high temperature, poor heat radiation, short service life and poor cruising ability of the power batteries in the use process are dynamically solved. When the maintenance is needed, the maintenance cost can be greatly reduced, and meanwhile, the arrangement position of the battery box is very flexible. At ordinary times, too many battery pack modules do not need to be installed during the short-distance driving; partial battery pack modules can be put in a garage for standby or put in the garage for charging; the total weight of the electric automobile is greatly reduced.

Description

technical field [0001] The invention relates to a power type battery pack and its management system, in particular to a power type battery pack which can be plugged or pulled out quickly and an intelligent battery management system for an electric vehicle. Background technique [0002] In today's increasingly severe energy and environmental situation, electric vehicles have become an emerging industry that all countries and regions in the world pay more attention to because of their significant advantages in cleanliness and energy saving. Although electric vehicle products have been around for a long time, and the improvement of hardware technology has continuously achieved new results, the market promotion of electric vehicles has progressed very slowly, and many problems have been encountered in the promotion and popularization. The industrialization of electric vehicles still has a long time to go. way to go. [0003] One of the important reasons is that the battery life...

AI Technical Summary

Problems solved by technology

[0005] 1) The installation structure is complicated, and there are many connections between the battery packs. If you do not pay attention to the installation, the connection will be wrong, which will easily lead to a short circuit.

[0006] 2) Once the quality and performance of some batteries in the battery unit decline, they cannot be replaced

[0007] 3) When the battery unit needs to be maintained, the insulating film and fireproof board on it need to be disassembled. This operation process has many steps, takes a long time, is difficult, and most of the removed materials cannot be reused
