Embodiment Construction

[0015] Such as figure 1 As shown in , an electric vehicle (EV) includes a drive motor 10 (MG) and a battery 11 . Electric power is supplied from a battery 11 to the drive motor 10, and the drive motor 10 drives wheels 10a of the electric vehicle. The battery 11 is a plug-in battery charged by a commercial power station such as 100V before the electric vehicle starts running. The drive engine 10 also works as a generator. When the speed of the electric vehicle is decelerated, electric power is regenerated in the drive engine 10 by the deceleration energy, and the battery 11 is charged with the regenerated electric power.

[0016] In addition to driving the engine 10 , the electric power of the battery 11 is also supplied to other components of the electric vehicle, such as a compressor 21 or an electric heater 22 . The compressor 21 and the electric heater 22 constitute an air conditioner 20 that conditions the interior air of the passenger compartment of the electric vehicl...

Abstract

A detector (30) detects a remaining power of a battery (11). A calculator (31b) calculates a demand load of air-conditioning based on at least one of a preset temperature set for air in a passenger compartment of an electric vehicle and an outside temperature of air outside of the electric vehicle. A switching portion (31c) switches a mode of air-conditioning between a battery mode and an engine mode based on the calculated demand load and the detected remaining power of the battery. The battery mode causes the battery to supply electric power for air-conditioning, and the engine mode causes an engine (26) of the electric vehicle to supply combustion energy for air-conditioning.

Description

technical field [0001] The present disclosure relates to an air conditioning control device for an electric vehicle. Background technique [0002] Electric vehicles are required to have a long driving distance per charge. For example, the battery of a plug-in electric vehicle is charged by a commercial power station (100V) before driving. Electric vehicles are required to have a longer driving distance without additional charging when starting to travel in a fully charged state. [0003] JP-A-2010-12970 describes an electric vehicle having an engine air conditioning mode and a battery air conditioning mode. In the engine air conditioning mode, air conditioning is performed using a relatively small output of the engine. In the battery air conditioning mode, air conditioning is performed using electric power of the battery. [0004] In the engine air conditioning mode, a cooling operation is performed by driving a refrigeration compressor of a refrigeration cycle using a r...
