Problems solved by technology
At present, most battery management systems adopt the master-slave controller mode. There are a lot of wiring inside the battery pack, which makes the module layout inside the battery pack difficult. At the same time, the existence of a large number of wiring and physical connectors inevitably poses a risk of failure. These are the risk factors of power battery management system

The invention discloses an electric automobile battery management system communication framework based on a Bluetooth Smart Mesh. The framework comprises multiple power battery single bodies supplyingelectric energy to an electric automobile, multiple battery management slave controllers and a battery management master controller, wherein each battery management slave controller comprises an information acquisition and balancing control module and a Bluetooth slave module, the information acquisition and balancing control modules are used for conducting voltage acquisition, temperature acquisition and balancing control on the power battery single bodies, and voltage acquisition and temperature acquisition results are transmitted to the battery management master controller through the Bluetooth slave modules; and the battery management master controller comprises a Bluetooth master module and an MCU and is used for acquiring information of the total voltage, the total current and the insulation resistor state, sending the above information to a vehicle control unit through a vehicle CAN bus, receiving a command, sent by the vehicle control unit, through the vehicle CAN bus and sending balancing commands to the battery management slave controllers through the Bluetooth master module. The framework has the beneficial effects that physically-arranged wires are reduced, and the communication reliability of a battery management system is improved.
Description
technical field [0001] The present invention relates to the field of new energy battery management, in particular, to a communication architecture of an electric vehicle battery management system based on Bluetooth SmartMesh. Background technique [0002] Electric vehicle power batteries have high requirements for safety, and the battery management system is used to ensure the safety of the battery and improve the service life of the battery. The battery management system needs to transmit a large amount of data in a timely and reliable manner to ensure effective management of the power battery. At present, most battery management systems adopt the master-slave controller mode. There are a lot of wiring inside the battery pack, which makes the module layout inside the battery pack difficult. At the same time, the existence of a large number of wiring and physical connectors inevitably poses a risk of failure. These are the risk factors of the power battery management system...
