Battery protective plate for lithium iron phosphate power battery Active balanced charging system topology, battery protection plate active equalization is a balanced manner relative to passive balance, and is defined, refers to the use of active components to implement battery pack. Ways of balanced capacity.The system is mainly composed of a monomer battery protection board and a vehicle controller. The monomer battery management circuit is composed of a monomer battery detecting unit and a monomer battery equilibrium charging unit, and the detecting unit uses an adaptive KalMan filtering algorithm to calculate a cell battery. The SOC, the balanced charging unit uses the flyback converter to accommodate the battery of the battery group to the unit SOC, so that each single cell SOC is consistent within the control range.
The communication method between each unit cell management circuit is used to communicate between CAN bus, and the monomer battery management circuit and the vehicle controller are communicated over the CAN-USB bus adapter. The vehicle controller is connected to the CAN bus of the monomer battery management circuit via the USB-CAN bus adapter, and the transmission and reception of the unit battery management circuit information is realized. By using the distributed structure of the CAN bus, the connection between the system is reduced, which is convenient for system installation and commissioning. The battery pack management system is constituted by the N-section monomer battery management circuit, as shown in FIG. 3.2, for the connection line diagram of the monomer battery management circuit and the unitary battery when n = 4.
Communication and connection between the single battery protection board management circuit, the CAN bus consists of 4 signal lines, GND_CAN is the external power supply interface, CANL is the CAN bus L signal, canh is a CAN bus H signal, + 5VCAN For the CAN module + 5V power external power supply interface. ODD represents an odd module, Even represents the even module. The monomer battery management circuits respectively lead two lines to be connected to the monomer battery, so that it can be disconnected from the monomer battery management circuit at any time.
