Abstract

The invention relates to the technical field of automobiles, and discloses a battery temperature control method and device which are used for controlling a fan to cool a battery. The method comprises the following steps of: acquiring a current battery temperature; according to the corresponding relation between the battery temperature and the duty ratio of the fan, determining a target duty ratio corresponding to the current battery temperature; and controlling the fan to operate according to the target duty ratio so as to cool the battery. According to the control method and device, the influence of battery over-temperature on the performance of the whole vehicle can be effectively avoided.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a method and device for controlling battery temperature. Background technique [0002] The 48V light hybrid system can increase the standard voltage of vehicle equipment to 48V, enabling the vehicle to drive a more powerful vehicle system. In practical applications, in a 48V light-hybrid system, when the SOC (State of Charge, remaining power) of the battery is below 40%, the battery temperature rises faster, which may cause the battery temperature to exceed its operating temperature requirements. [0003] In the related art, when the battery is overheated, the temperature of the battery is usually reduced by limiting the output power of the power system. However, this cooling method will sacrifice the power of the vehicle, thereby affecting the control of the vehicle. Contents of the invention [0004] In view of this, the present application provides a battery tem...
