The invention discloses a hybrid power energy storage system and a control method thereof, and a hybrid power vehicle. The system comprises a battery module, a super capacitor module and a dual three-phase synchronous motor. The battery module is connected with the A,B, and C windings of the double three-phase synchronous motor; and the super capacitor module is connected to the UVW windings of the dual three-phase synchronous motor. The battery module includes a fuel cell, a lithium battery, a DC converter and a first inverter; and the lithium battery is connected in parallel to DC side of the first inverter by the DC converter and the fuel cell. The super capacitor module includes a super capacitor and a second inverter; and the super capacitor is arranged at the DC side of the second inverter. With the dual three-phase synchronous motor, the number of DC converters is reduced, so that the stability of the system is improved, the complexity of the parameter design is reduced, and thesize of the hybrid vehicle is reduced. Besides, the good power management is provided.
Description
technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, and more specifically relates to a hybrid energy storage system, a control method thereof, and a hybrid electric vehicle. Background technique [0002] With the progress of the times, people began to pay attention to the problems that must be faced in the process of social development such as energy shortage and environmental protection. Therefore, the hybrid electric vehicle, a new type of automobile industry, has received extensive attention. The hybrid energy storage system is an indispensable core part of a hybrid vehicle. Based on the advantages and disadvantages of various energy sources such as batteries and supercapacitors, the hybrid energy storage system combines them to achieve the purpose of reducing power consumption, improving efficiency and maximizing economy. In fact, after years of development and research by various countries and enterprises, hybrid energy sto...
