Although lithium batteries have more advantages than other types of batteries, there is a danger of explosion when lithium batteries are in a severely overcharged state, which can cause damage to the lithium batteries and threaten the safety of users. Therefore, it is necessary to equip the lithium battery with a set of lithium battery management system to effectively monitor, protect, energy balance and fault alarm of the battery pack, thereby improving the working efficiency and service life of the entire lithium battery.

What is BMS?

BMS is the abbreviation of Battery Management System. It is a system for battery management. It usually has the function of measuring battery voltage to prevent or avoid abnormal conditions such as battery over-discharge, over-charge, and over-temperature.

The functions of BMS

1. Battery overcharge, over discharge, over temperature, over current, and short circuit protection. Once the voltage of any battery exceeds 4.2V or the voltage of any battery is lower than 3.0V, the system will automatically cut off the charging or discharging circuit. If the battery temperature exceeds the battery operating temperature or the current is greater than the battery discharge current, the system will automatically cut off the current path to ensure the safety of the battery and the system.

2. Energy balance. The entire battery pack consists of many batteries in series. After a certain period of operation, due to the inconsistency of the battery cell itself, the inconsistency of the operating temperature and other reasons, it will eventually show a big difference, which will affect the life of the battery and the use of the system. Energy balance is to make up for the differences between the individual cells to do some active or passive charging or discharging management to ensure the consistency of the battery and prolong the life of the battery.

As a powerful guarantee for the safe use of batteries, BMS makes the battery in a safe and controllable charging and discharging process at all times, greatly improving the cycle life of the battery in actual use.
