The invention provides an electric automobile, an auxiliary driving device and a control method.The auxiliary driving device comprises an elastic force energy storage unit, a transmission, a generator motor, a lead-acid battery unit, a sensing unit and a control unit, and the elastic force energy storage unit comprises a rotating shaft and a plurality of elastic force energy storage modules independently arranged on the rotating shaft; each elastic energy storage module comprises a volute spiral spring, a shell, a brake, a transmission sleeve and a bearing. The invention mainly aims to solve the problems of combustion or explosion caused by thermal runaway of a lithium battery in a closed space for a long time during long-distance transportation of the pure electric vehicle, such as on-sea long-distance transportation, and the problem that the vehicle breaks down on a road due to the fact that the endurance mileage of the pure electric vehicle is greatly shortened in a cold season. The auxiliary driving device provided by the invention can replace a lithium battery of the pure electric vehicle to provide a temporary power source for the pure electric vehicle, so that the spontaneous combustion risk in the transportation process is reduced, and the safety is improved.

    本发明提供了一种电动汽车、辅助驱动装置及控制方法,所述辅助驱动装置包括弹力储能单元、变速器、发电电动机、铅酸电池单元、传感单元和控制单元,弹力储能单元包括转轴和独立设置于其上的若干弹力储能模块,各弹力储能模块均分别包括涡卷弹簧、外壳、制动器、传动套和轴承。本发明主要针对纯电动汽车在长途运输,如海上长途运输过程中长时间在密闭空间内由锂电池热失控导致的燃烧或爆炸,以及在寒冷季节由于纯电动汽车续航里程大幅缩短导致的汽车路上抛锚等问题提出,在上述场景中,可由本发明提供的辅助驱动装置代替纯电动汽车的锂电池,为纯电动汽车提供临时动力源,降低了运输过程中的自燃风险,提高了安全性。
