It is the first letter abbreviation combination of BATTERY MANAGEMENT SYSTEM, which is called the battery management system. Commonly known as battery nanny or battery housekeeper; battery management system (BMS) is mainly for the intelligent management and maintenance of each battery unit, preventing the battery from overcharging and overdischarging, extending the battery life, and monitoring the status of the battery.

The ZK series BMS battery management system of Zhengling Technology realizes the following functions:

(1) Measurement of battery terminal voltage

(2) Energy balance among single cells:

That is, the single battery is charged in a balanced manner, so that each battery in the battery pack reaches a balanced and consistent state. Equalization technology is the key technology of a battery energy management system that is currently being researched and developed in the world.

(3) Total voltage measurement of battery pack

(4) SOC calculation:

Accurately estimate the state of charge (SOC) of the power battery pack, that is, the remaining battery capacity, to ensure that the SOC is maintained within a reasonable range, and to prevent damage to the battery due to overcharge or overdischarge

(5) Dynamically monitor the working status of the power battery pack:

During the battery charging and discharging process, the terminal voltage and temperature of each battery in the battery pack, the charging and discharging current and the total voltage of the battery pack are collected in real time to prevent the battery from being overcharged or overdischarged.

(6) Real-time data display

(7) Data recording and analysis

At the same time, select the problematic battery to maintain the reliability and efficiency of the entire battery pack

(8) Communication networking function
