基于控制目标的氢-电混动系统能量管理策略综述

Hydrogen fuel cells, as the energy supply device, have received a lot of attention because of their high energy density and low carbon emission characteristics. However, due to the insufficient hydrogen refueling infrastructures, the hydrogen cost is high, and the dynamic response of hydrogen fuel cells is poor. Therefore, the hybrid power system of rechargeable battery and hydrogen fuel cells is generally used to supply energy to vehicles such as unmanned aerial vehicles (UAV), cars, and others. The energy management strategy of hybrid power system has an impact on the parameters of system dynamic response, economy and battery life. So the selection and design of energy management strategy are crucial to hybrid power system. This paper introduced the working principle of hydrogen-electricity hybrid power system and its energy supply methods. Besides, the current status of application and research progress of different energy management strategies for various application scenarios were summarized according to different control objectives. Finally, this paper presented the challenges of hybrid energy management strategies and outlooks their future development direction.
