摘要：
An active balance circuit based on the topology of flyback transformer is proposed in the article for the balance management of high capacity Lithium-ion battery packs in space. The circuit can control the value of the balance current by fixed duty cycle control, to achieve balance function for Lithium-ion battery packs. Compared to passive equilibrium circuit, the active balance circuit can effectively improve the balance speed of the high-capacity battery packs, meeting the requirement of balance speed and reducing the energy loss of the battery packs, increasing the service life of the battery packs. The balance circuit can realize modular and control simple. The hardware circuit was built for the project. The experiment results prove the correctness and effectiveness of the scheme.
