A refrigerant circulation apparatus includes: a vehicle-interior air conditioning () that cools an interior of a vehicle; an on-vehicle battery cooler () that includes an evaporator for on-vehicle battery cooling () that cools an on-vehicle battery mounted on the vehicle; and an electric compressor () that compresses and supplies a refrigerant to at least one of the vehicle-interior air conditioning () and the on-vehicle battery cooling (). The apparatus also includes: a temperature sensor () that detects a temperature of the electric compressor (); a pressure sensor () that detects a pressure of the refrigerant compressed by the electric compressor (); and a control unit () that restricts operation of the evaporator for on-vehicle battery cooling () to reduce load on the electric compressor () based on the temperature of the electric compressor () and the pressure of the refrigerant.

A charge control device for a hybrid vehicle includes a driving battery supplying electric power to front and rear motors. It can switch between a normal power generation mode in which an engine is driven at a first rotational speed higher than an idling speed to generate electric power and charge the driving battery to a predetermined amount of charge, and a forced power generation mode in which the engine is forcedly driven at the first rotational speed or higher to generate electric power and charge the battery so as to maintain a higher amount of charge of the driving battery than a predetermined amount of charge, and drives the engine at an idling speed or lower to reduce an amount of electric power generation if the cooling water of the engine is a first predetermined temperature or higher when the forced power generation mode is performed.
