Abstract

The invention provides a heating method and device for a power battery and electronic equipment. The heating method comprises the steps of obtaining the remaining electric quantity of a to-be-heated power battery, the temperature of the to-be-heated power battery and the distance of a to-be-driven route; under the condition that the residual electric quantity is greater than a preset electric quantity threshold value, determining a vehicle driving distance when the to-be-heated power battery is heated to a target temperature based on the temperature of the to-be-heated power battery; and determining whether to turn on a heating source to heat the to-be-heated power battery based on the vehicle driving distance and the distance of the to-be-driven route. When whether the heating source is started to heat the to-be-heated power battery or not is determined, various factors such as the remaining electric quantity of the to-be-heated power battery, the distance of the to-be-driven route and the vehicle driving distance when the to-be-heated power battery is heated to the target temperature are considered; the endurance mileage, the dynamic property and the service life of the power battery can be well balanced, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a heating method, device and electronic equipment for a power battery. Background technique [0002] At present, vehicle electrification has become a development trend. As we all know, the charging and discharging power and capacity of power batteries at low temperatures are greatly attenuated. If the vehicle is running, heating the power battery will consume the power of the power battery itself, resulting in serious attenuation of cruising range; if the power battery is not heated, the battery will continue to be low due to the slow self-heating of the battery, resulting in poor power performance and user experience. Poor, and long-term low temperature has a greater impact on life. [0003] The existing strategy for heating the power battery is: detecting the temperature of the power battery, and comparing the detected temperature of the power battery with a thres...
