The invention discloses an average kilometer energy consumption estimation method and device for a battery pack for a blade electric vehicle. The method comprises the steps that battery voltage Ubatt signals and battery current Ibatt signals sent by a battery controller, vehicle speed v signals sent by an ABS controller, vehicle gear signals sent by a gear shifting mechanism and air conditioner compressor ACCM power PACCM signals, warm air system PTC power PPTC signals and HVAC work state signals sent by an HVAC system are received; the average kilometer driving energy consumption eveh of the blade electric vehicle, the average kilometer energy consumption change value egear caused by gear switching and the average kilometer energy consumption ehvac of the HVAC system are obtained; the average energy consumption of the vehicle is obtained. According to the average kilometer energy consumption estimation method and device for the battery pack for the blade electric vehicle, due to the fact that the energy consumption change caused by switching of on/off and gears of the HVAC system is independently calculated, the effect on the residual mileage can be presented instantly, and accordingly accurate average kilometer energy consumption of the battery pack for the blade electric vehicle can be obtained.
