AI Technical Summary

Technical Problem

In existing technologies, the timing of battery temperature control before driving is not accurately determined, which may result in the battery temperature being the same as the ambient temperature, leading to energy waste.

Method used

Based on the initial battery parameters of the power battery at the preset temperature control time point, the advance start time is determined, and combined with the vehicle usage time, the target temperature control time point is precisely set, and the battery temperature is adjusted through the temperature control component.

Benefits of technology

It improves the accuracy of battery temperature control, reduces the possibility of the battery temperature matching the ambient temperature, and reduces energy waste.

Abstract

The application relates to the technical field of vehicle thermal management, and provides a battery temperature control method and device for a vehicle. The method comprises the following steps: determining an early opening duration for temperature control of a power battery according to initial battery parameters of the power battery at a preset temperature control time point; determining a target time point for temperature control of the power battery according to the early opening duration and a vehicle use time point of the vehicle carrying the power battery; and controlling the power battery to perform temperature adjustment at the target time point; wherein the initial battery parameters comprise at least one of an initial battery temperature or an initial battery state of charge. The battery temperature control method for the vehicle provided in the application can effectively control the temperature of the battery and reduce energy waste.
