Title:
METHOD AND DEVICE FOR CONTROLLING TEMPERATURE OF POWER BATTERY OF ELECTRIC AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2019/001483
Kind Code:
A1
Abstract:
The present application provides a method and device for controlling the temperature of a power battery of an electric automobile. The method comprises: when it is determined that an electric automobile is at a static state, obtaining a current temperature value of a single cell of a power battery of the electric automobile; and when it is determined that a current lowest temperature value of the single cell of the power battery is lower than a heating temperature threshold, starting a heating system to carry out heating treatment on the power battery. Accordingly, when the electric automobile is in the static state, the temperature of the power battery in the electric automobile is controlled, and the problems that the electric automobile cannot enter a slow-charge charging state in time and rapid-charge charging cannot be started when the electric automobile is at the static state for long time and the current lowest temperature value of the single cell of the power battery is lower than the heating temperature threshold are resolved; and impacts on the power battery caused by the low environment temperature are avoided, thereby prolonging the service life of the power battery and improving user experience.
