METHOD AND DEVICE FOR DETERMINING BATTERY PACK TEMPERATURE DIFFERENCE OF NEW ENERGY VEHICLE, AND CONTROL METHOD

摘要

A method and device for determining a battery pack temperature difference of a new energy vehicle, and a control method. The method comprises: arranging multiple temperature sensors at multiple predetermined positions of a battery pack; receiving detection values respectively provided by the multiple temperature sensors, and performing first discarding processing on the detection values, the first discarding processing comprising: discarding a detection value greater than a first predetermined threshold value or less than a second predetermined threshold value; calculating a first mean value of the remaining detection values after the first discarding processing, calculating a first standard difference on the basis of the first mean value, and performing additional processing on the remaining detection values after the first discarding processing, the additional processing comprising: performing second discarding processing, i.e., discarding a detection value of which the absolute value of a difference from the first mean value is greater than a predetermined times of the first standard difference; and determining a difference between a maximum value and a minimum value in the remaining detection values after the additional processing as a temperature difference of the battery pack.
