Abstract
A high-energy-efficiency lithium battery monorail hoist locomotive includes a driving unit, a battery unit and a bearing trolley. The bearing trolley bears cargoes, the battery unit outputs the power to the driving unit, and the driving unit drives the locomotive to move. The battery unit includes a battery management system (BMS), an ultra capacitor and a battery pack formed by single cells. The BMS obtains the minimum state of charge difference value ΔSOCmin between the single cells, the state of charge SOCn of each single cells, the maximum state of charge SOCmax among the single cells and the minimum state of charge SOCmin among the single cells. The ultra capacitor and the battery pack are controlled by the BMS to charge and discharge. The charging and discharging of the battery pack are managed by the BMS, and the ultra capacitor plays a buffering role in the charging and discharging process.
