Problems solved by technology

[0003] Although the production technology of lithium batteries is becoming more and more mature, the BMS battery management system of lithium battery system and its protection function can effectively protect the battery, but it is still difficult to avoid accidental safety problems during the use of the battery. It is impossible to easily and conveniently detect the health status of the battery in real time to determine whether the battery is safe, resulting in accidents

Abstract

The invention discloses a battery health diagnosis method. The method comprises: a user background obtaining detailed information of a battery through a BLE technology; checking whether the BMS reports active abnormal information or not; if so, popping up a warning window by the user, and prompting the user to maintain; and if not, the user background diagnosing and analyzing the received detailedinformation of the battery. Battery parameter information is obtained through a user background, and the state of the battery is analyzed according to the battery parameter information, therefore, the battery fault condition can be judged, a terminal consumer can know the battery condition by himself / herself to obtain detailed information of the battery and judge whether a fault exists in the battery or not, battery repair suggestions and after-sales service are pushed to a user in time, and the user can enjoy better after-sales service.

Description

technical field [0001] The invention relates to the technical field of battery management, in particular to a method for battery health diagnosis. Background technique [0002] Nowadays, the demand for power batteries in the new energy industry is increasing in daily life, and the range of use of power batteries is also very wide, so there are more and more safety accidents caused by power batteries. Lithium batteries mainly collect battery data such as voltage, current, battery balance, temperature monitoring at each point, and SOC through the BMS battery management system, and then protect them through overvoltage protection, overcurrent protection, overdischarge protection, short circuit protection, and temperature protection. function to protect the battery. [0003] Although the production technology of lithium batteries is becoming more and more mature, the BMS battery management system and its protection functions of lithium battery systems can effectively protect th...
