Problems solved by technology

[0003] However, the battery itself has temperature characteristics. In a low-temperature environment, the charging efficiency of the battery is low, especially for energy-type batteries. Some batteries cannot be charged when the temperature is lower than 5°C, which affects the recovery of braking energy. thus affecting the mileage

Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application , but not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0036] The popularity of new energy vehicles is getting higher and higher, because they are powered by batteries and will not cause exhaust emissions. However, the battery capacity is limited and the charging speed is relatively slow, which makes the cruising range an important indicator of the performance of new energy vehicles. In order to increase the cruising range, the energy in the vehicle system must be fully util...

Abstract

The invention provides a battery heating control method, device and system, a storage medium and a vehicle. The method comprises the steps of detecting the temperature of a battery of the vehicle; ifthe temperature of the battery is less than or equal to a first preset temperature, controlling a generator of the vehicle to supply power to a brake resistor to heat the battery with the heat generated when the brake resistor works; and if the temperature of the battery is greater than the first preset temperature, controlling the generator to supply power to the battery. When the temperature ofthe battery is lower than the first preset temperature, the braking energy is used for heating the battery so as to improve the charging capacity of the battery; and after the battery temperature is higher than the first preset temperature, the braking energy is used for supplying power to the battery, and the braking energy recycling effect is achieved. Through the method, the charging performance of the battery of the vehicle in a low-temperature environment can be improved, the braking energy recovery efficiency is improved, and the endurance mileage of the vehicle is prolonged.

Description

technical field [0001] The present application relates to vehicle control technology, and in particular to a battery heating control method, device, system, storage medium and vehicle. Background technique [0002] The popularity of new energy vehicles is getting higher and higher, because they are powered by batteries and will not cause exhaust emissions. However, the battery capacity is limited and the charging speed is relatively slow, which makes the cruising range an important indicator of the performance of new energy vehicles. In order to increase the cruising range, the energy in the vehicle system must be fully utilized to reduce unnecessary waste. Therefore, many vehicles are equipped with a braking energy recovery system, which converts the energy released by the vehicle during braking or coasting into electrical energy and stores it in the battery to supplement the power consumption of the battery and extend the cruising range. [0003] However, the battery its...
