Therefore, a master-slave battery charging system using parallel DC-DC converters is presented. The master charger acts as a voltage or current source, and multiple slave chargers are turned on and off by the master as current sources. With it, the heat is spread out into multiple locations on the PCB, effectively eliminating thermal hot spots.
In this paper, a master-slave power battery management system based on STM32 microcontroller is designed. It adopts modular and master-slave design, and realizes the communication between host and slave by CAN bus. In this paper, the 270 V battery pack is designed, that is, the battery pack is composed of 76S12P (76 series 12 parallel) 18650 cells.
As the ‘brain’ of the battery management system, the master control module is responsible for data analysis, fault judgment, SOC calculation, data storage and external communication. As shown in Fig. 4, after the system is powered on, the system parameters, peripherals, etc. are initialized.
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.
The master charger acts as a voltage or current source, and multiple slave chargers are turned on and off by the master as current sources. With it, the heat is spread out into multiple locations on the PCB, effectively eliminating thermal hot spots. With one slave, the constant-current (CC) phase charging time was reduced by 46%.
