What is a master-slave battery management system (BMS)?
The Master-Slave Battery Management System (BMS) is an innovation that seamlessly combines performance, safety, and sustainability. Read on to learn more about the master-slave BMS architecture, and the basic installation components, and then get to know how to choose the right master-slave BMS board.
What is a master slave BMS?
Purpose of Master, Slave BMS. The main master BMS (or battery controller) controls elements such as battery chargers, contractors and external heating or cooling drivers. Battery state algorithms were programmed to calculate the State of charge, State of health, and power capability.
How do BMS slaves work?
Six cells (each having a voltage range of 15 V–25.2 V) are connected in series to form a battery module and the BMS Slaves provide the balancing among the cells of the respective module. The BMS Master performs the balancing operation in the battery pack formed by the connection of three battery modules.
What happens if a BMS slave unit fails?
If one slave unit fails, the master unit can still operate and manage the other slave units, reducing the risk of a complete system shutdown. Efficiency: By monitoring individual cells or modules, the BMS master slave system can optimize the charging and discharging process, thereby increasing overall efficiency and extending battery life.
What is a BMS slaves & a 6s1p battery module?
The BMS consists of a BMS Master, three BMS Slaves and three 6S1P battery modules. Primarily, the BMS Slaves provide the active cell balancing for each 6S1P battery module. Secondly, BMS Master helps to solve the imbalance problem among the three 6S1P battery modules.
What is the difference between a BMS and a slave unit?
The main BMS is responsible for relatively many functions, including calculation, prediction, decision-making, communication, etc. The slave unit is basically only responsible for measurement. In this way, it can be said to inherit most of the advantages of the modular structure, while also reducing the cost of expansion.
