Problems solved by technology

[0003] At present, the battery heating termination temperature generally adopts a unified temperature threshold. When the temperature is lower than the temperature threshold, the heating will start, and the heating will stop when the temperature reaches this temperature. There is no precise temperature threshold for different driving habits.

Abstract

The invention discloses a heating control method and device, equipment and a storage medium. The method comprises the steps: when a vehicle is in a high-voltage power-on state, the battery temperature, the environment temperature and a battery state-of-charge value are obtained; if the battery temperature is smaller than a battery temperature threshold value, the environment temperature is smallerthan an environment temperature threshold value, and the battery state-of-charge value is larger than a state-of-charge value threshold value, a battery is heated; and the target cut-off temperatureis determined according to historical data of the vehicle, and heating is stopped when the battery is heated to the target cut-off temperature. Through the technical scheme of the heating control method and device, the equipment and the storage medium, different battery heating stop temperatures can be formulated for different driving behavior habits of each vehicle on the basis of basically meeting the dynamic property requirements of different drivers; when the requirements of the drivers for the performance of the battery is not strong, energy waste caused by the over-high heating temperature can be prevented; and meanwhile the braking energy recovery rate at the low temperature can be increased to a certain extent, and the energy-saving effect at the low temperature is achieved.

Description

technical field [0001] Embodiments of the present invention relate to vehicle technology, and in particular to a heating control method, device, equipment and storage medium. Background technique [0002] In severe winter conditions, the performance and discharge capacity of vehicle power batteries will be greatly attenuated, coupled with the use of warm air and increased resistance in winter, resulting in a significant reduction in driving range and a decline in vehicle power performance. The power battery heating function has become an important way for many electric vehicles to solve such problems. Through the battery heating function, the temperature of the power battery is raised to make it out of the low temperature and restore its maximum power capacity for discharging and charging. At the same time, under the premise of satisfying the dynamic performance of the vehicle in winter, the braking energy can be recovered as much as possible, which is beneficial to prolongi...
