The invention discloses an injection type battery heat preservation device. The device comprises a battery heat preservation sleeve, a motor shell and an injection pipe. The wall of the motor shell ishollow; the upper part of the motor shell is communicated with the injection pipe; the lower part is communicated with the battery heat preservation sleeve; and the battery heat preservation sleeve wraps the battery pack. In the vehicle running process, a medium liquid is pumped out of the battery heat preservation sleeve through the injection pipe to absorb heat generated when the motor works, and water in the motor shell flows back to the battery heat preservation sleeve to preserve heat of the battery pack after the motor is stopped and powered off, so that the battery pack is not in a low-temperature state when started next time, the endurance mileage of the electric vehicle in winter is increased, and remarkable technical progress is achieved in the field.

    本发明公开了一种注射式电池保温装置,它包括电池保温套、电机外壳、注射管;所述电机外壳的壁为中空,其上部连通所述注射管,其下部连通所述电池保温套,电池保温套包裹于电池组外,可在汽车运行时,由注射管将介质液抽出电池保温套,吸收电机工作时的热量,并在停车断电后将电机外壳内的水流回至电池保温套,对电池组进行保温,使电池组能在下次启动时,不处于低温状态,提高了冬季电动车的续航里程,在本领域有显著技术进步。
