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.

A tensioner for a hybrid electric vehicle adjusts tension of the belt which is provided to synchronize rotation of a pulley of a starting motor shaft and rotation of a pulley of a crankshaft. The tensioner for a hybrid electric vehicle may include: a base arm, a driving arm pivotably connected with the base arm, and a driven arm pivotably connected with the base arm. The tensioner further includes an actuator operating so as to autonomously vary an entire length so that one end thereof is fixed to the base arm and the other end thereof is connected with the driving arm; a first pulley rotatably connected with the first pulley connecting portion or the driving arm and rolling while contacting the belt; and a second pulley rotatably connected with the second pulley connecting portion of the driven arm and rolling while contacting the belt.

A hybrid vehicle is provided and includes an input that receives user selection for terrain mode and a HSG connected to the engine to operate as a start motor to turn on the engine. The HSG operates as a generator that performs idle charging when the engine is turned on. A battery is electrically connected to the HSG. A controller configured perform idle charging when SOC of the battery is less than or equal to a first SOC through the HSG by turning on the engine.

A method for operating a vehicle that includes a DC/DC converter is described. In one example, the method includes adjusting an output voltage of the DC/DC converter to increase torque of a belt integrated starter/generator. The output voltage of the DC/DC converter may be adjusted before and during engine cranking.
