Intelligent supervision system of full life cycle of power lithium battery

Abstract

The invention discloses an intelligent supervision system of the full life cycle of a power lithium battery. The intelligent supervision system comprises a power battery pack unit, a high-voltage control unit, a grouped battery management unit, a wireless transmission unit, a cloud management system and a user terminal. The power battery pack unit comprises a plurality of power battery pack sub units connected in parallel, each power battery pack sub unit comprises a plurality of single-group battery modules connected in series, and each single-group battery module comprises a battery pack, a sampling protection unit, a single-group battery management unit and an isolated communication module; the sampling protection units collect the batteries packs, the single-group battery management units calculate the health states and electricity quantity states of the battery packs and send the states to the cloud management system and the user client through the wireless transmission unit. The intelligent supervision system of the full life cycle of the power lithium battery has the following advantages that the battery packs can be managed independently, the use safety of the lithium battery packs can be improved, echelon-shaped recycling and utilization can be facilitated, and the effective utilization rate of the battery packs can be raised.

Description

technical field [0001] The invention relates to the field of battery supervision, in particular to an intelligent supervision system for the whole life cycle of a power lithium battery. Background technique [0002] An electric vehicle is an electric drive vehicle, also known as an electric drive vehicle. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, an electric vehicle is a vehicle that uses a battery as an energy source, and converts electrical energy into mechanical energy through components such as a controller and a motor, so as to control the magnitude of the current to change the speed of the vehicle. In the traditional technology, when managing the batteries of electric vehicles, the management of each battery pack is not independent, but through direct parallel connection of all battery packs. When a single battery is abnormal, It will affect the work of other battery packs and directly damage all the batteri...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that, aiming at the problems in the prior art that each battery pack cannot be managed independently, the lithium battery pack is less safe to use, it is not conducive to the cascade recycling of batteries, and the effective utilization rate of the battery pack is low. Deficiencies, provide a power lithium battery full life cycle intelligent supervision system that can independently manage each battery pack, improve the safety of lithium battery packs, facilitate the cascade recycling of batteries, and improve the effective utilization rate of battery packs
