Abstract

The invention discloses a battery pack intelligent preheating method and electronic equipment. The battery pack intelligent preheating method comprises the steps of detecting whether a charging gun isconnected or not in response to a preheating request; and if the charging gun is connected, supplying the electric quantity output by the charging gun to a heating unit and heating a battery pack bythe heating unit. The electronic equipment comprises at least one processor and a memory which is in communication connection with the at least one processor, wherein the memory stores an instructionwhich can be executed by at least one processor, and the instruction is executed by the at least one processor so that the at least one processor can execute the battery pack intelligent preheating method. People can send a preheating command to control the charging gun to output electric quantity to the heating unit for heating so that the temperature of the battery pack can be increased in a low-temperature environment, the battery pack can keep enough electric quantity, and the cruising ability is ensured.

Description

technical field [0001] The invention relates to the field of electric vehicle equipment, in particular to an intelligent preheating method for a battery pack and electronic equipment. Background technique [0002] Electric vehicles have good environmental friendliness and driving comfort, coupled with policy incentives in recent years, more and more users choose to buy electric vehicles instead of fuel vehicles. Electric vehicles use rechargeable battery packs, compared to fuel vehicles that use gasoline or diesel as their energy source. [0003] The types of battery packs mainly include ternary lithium batteries and lithium iron phosphate batteries. In a low temperature environment, such as the winter environment in northern my country, the charge and discharge capacity and capacity of these two batteries have dropped significantly, and the decline in the properties of these two batteries will cause the driving performance and cruising range of electric vehicles to also dr...
