Abstract:The stable operation of aluminum-air new energy battery involving with wind fluid thermal and many other factors, the demand for aluminum-air battery system run real-time monitoring of the status parameters, design a the aluminum-air battery management system based on CAN bus. Through the design of the system CAN interface, CAN communication protocol, CAN data transmission is aluminum-air battery automated management. The application of the system in a certain type of aluminum-air new energy power plants, and the results showed that: the system can take advantage of the real-time monitoring of the CAN bus monitoring parameters and stable operation of aluminum-air battery, failure to timely diagnosis system for aluminum-air battery engineering applications has practical value.
