Temperature control method, vehicle, and storage medium

Abstract

The embodiment of the invention discloses a temperature control method, a vehicle and a storage medium. The temperature control method comprises the steps that the first working temperature T1 of a battery is obtained; determining whether the battery can be started or not based on the first working temperature T1; if the battery cannot be started, the engine is started to drive the generator to operate; the generator charges a battery, and the generator supplies power to a plurality of heating elements of the hybrid vehicle to increase the temperature of a driving motor, the generator, the engine and the battery. According to the temperature control method, the vehicle and the storage medium, heat preservation and heating of the driving motor, the generator, the engine and the battery in the low-temperature environment can be achieved, the working performance and efficiency are improved, and the consistency of the whole vehicle drivability is kept.

Description

technical field [0001] The present application relates to the field of power battery thermal management, and in particular, to a temperature control method, a vehicle, and a storage medium. Background technique [0002] At present, with the rapid development of hybrid vehicles, they have the advantages of both electric vehicles and fuel vehicles, and have the advantages of low fuel consumption, low emissions, low pollution, and low noise, and have received widespread attention. The battery of a hybrid vehicle supplies power to the drive motor to provide power. However, due to the characteristics of the battery, in a low temperature environment (such as winter in Northeast China), the charging and discharging power of the battery will be severely limited, which will greatly affect the vehicle's performance. The working state makes the driving experience of hybrid vehicles in a low temperature environment extremely poor. In addition, when working at an unsuitable ambient temp...

AI Technical Summary

Problems solved by technology

The battery of a hybrid vehicle supplies power to the drive motor to provide power, but due to the characteristics of the battery, in low temperature environments (such as winter in Northeast China), the charging and discharging power of the battery will be severely limited, which will greatly affect the performance of the vehicle. The working state makes the driving experience of hybrid electric vehicles extremely poor in low temperature environments

In addition, when working in an unsuitable ambient temperature, the driving motor, generator, and engine of the hybrid system need to be preheated for a period of time before driving, otherwise the working performance, efficiency, and service life will be attenuated.
