A lithium battery management system

Abstract

The invention discloses a lithium battery management system. The lithium battery management system comprises a control processing module, and an information interaction module, a vehicle control module, a capacitor power module, a lithium battery power module and a sensing detection module which are electrically connected with the control processing module, wherein the capacitor power module and the lithium battery power module are connected with the vehicle control module; the control processing module is used for analyzing and processing vehicle state information as well as power supply system information and sending out a corresponding control instruction; the information interaction module is used for achieving information exchange between a vehicle owner and a vehicle; the vehicle control module is used for guaranteeing normal driving of the vehicle; the capacitor power module is used for supplying large current for a short period of time so as to protect voltage and current stability of a vehicle circuit; the lithium battery power module is used for supplying power when the vehicle drives normally; the sensing detection module is used for detecting the temperature and voltageand current information of the vehicle. The lithium battery management system not only reduces damage caused by the driving habits of a driver to a lithium battery of the vehicle, but also provides temperature protection for the lithium battery.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery management system. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream now. [0003] Lithium battery packs currently on the market. The management systems on electric vehicles are all established in normal electrical mode. However, in recent years, our company has conducted a summary of the after-sales of lithium batteries sold and found that the abnormal conditions of lithium batteries include capacity reduction and damage. Reasons for capacity reduction Through tracking...

AI Technical Summary

Problems solved by technology

However, the capacity reduction caused by the abnormal heating of the lithium battery pack caused by the driver's rapid acceleration and driving at a speed much higher than the optimal driving speed for a long time cannot be recovered.

At the same time, the high temperature in summer can easily cause abnormal temperature of the battery, which has certain defects.
