Abstract
In an air conditioner for a hybrid vehicle, when a residual charging degree of a battery becomes equal to or lower than a target degree, the electrical motor generator is driven by a vehicle engine so that the battery is charged through the electrical motor generator. When the engine is driven, the target degree of the battery is set higher than that when the engine is stopped so that a charging operation tends to be required while the engines driven. Accordingly, the frequency for starting the engine only for charging the battery is reduced.
