A method and system for an electric vehicle include a controller and a battery cooling system. The controller automatically detects when the vehicle is being driven to a charging station. The controller controls the battery cooling system to pre-cool a traction battery of the vehicle as the vehicle is being driven to the charging station so that the traction battery is cooled to a target temperature upon the vehicle reaching the charging station. The battery cooling system includes a phase change material (PCM) surrounding at least a portion of the traction battery. The traction battery is pre-cooled by circulating refrigerant coolant to the PCM to cool the PCM and thereby pre-cool the traction battery.

Method and system of predicting recharging of battery of vehicle at charging station and correspondent pre-cooling of the battery using cold storage as the vehicle is being driven to the charging station

A vehicle includes a first cooling loop, a second cooling loop, and a controller. The first cooling loop includes a compressor and a chiller. The second cooling loop includes a valve and an evaporator. The second cooling loop extends from an input side to an output side of the chiller on the first loop. The controller is programmed to, responsive to operation of the chiller but not the evaporator, close and intermittently pulse open the valve each time a discharge pressure of the compressor exceeds a first threshold.
