Abstract:

The aluminum-air battery and lithium-ion battery are formed into a hybrid power system, and the advantages and disadvantages of different topologies are analyzed to determine the topology of the hybrid power system. The principle of the aluminum-air battery hybrid power system was designed, the selection parameters of the key components of the system were determined, and the test platform of the hybrid power system was made. A rule-based control energy management strategy was proposed to improve the efficiency and lifetime of aluminum-air batteries. The strategy primarily considers the state of charge (SOC) of lithium-ion battery and load power variation so that the aluminum-air battery discharges at constant power in the high-power range and the Li-ion battery operates at variable power. The effectiveness of the strategy is verified through experimental testing.

Key words: aluminum air battery, hybrid power system, energy management strategy, rule control
