Outline
With the widespread application of lithium-ion batteries in industry and daily life, aiming at the existing problems of low energy utilization efficiency and long equalization time during battery pack equalization, the existing modular and reconfigurable circuits are improved, and a modular reconfigurable battery equalization circuit with multi-mode static charge-discharge operation is proposed. First, modularization processing and mathematical modeling of the equalization circuit are carried out. A bidirectional Cuk converter is used within the module; and a reconfigurable method is used for charging equalization between modules; discharge and static equalization dynamically modularize the battery pack with a bidirectional Buck-Boost converter. The battery equalization circuit is mathematically modeled, the working principle of the circuit is introduced, and the corresponding control strategies are developed for different equalization situations. Then, the simulation model of the proposed equalization circuit is constructed and compared with the traditional equalization circuit, and the equalization time, equalization efficiency and energy loss ratio of the circuit are analyzed. Finally, in combination with the hardware-in-the-loop simulation platform Typhoon, the battery equalization circuit is built, and the effectiveness of the proposed equalization circuit is verified.
