1. A control apparatus for an electric vehicle, comprising:
- a first inverter that supplies electric power to a motor that drives a vehicle;
a second inverter that supplies electric power to a load mounted in the vehicle;
a power storage unit that supplies electric power to the first and second inverters; and
a load control unit that selectively operates an air conditioner, a ventilator, and an air blower that are included in the load so as to maintain an in-vehicle temperature environment, in accordance with a power storage amount in the power storage unit or a condition amount and a predetermined setting value thereof,wherein the setting value consists of a first setting value and a second setting value that is smaller than the first setting value; and
wherein, in the case where the power storage amount becomes smaller than the first setting value, the air conditioner is slightly operated, and in the case where the power storage amount becomes smaller than the second setting value, the air conditioner is stopped, and at least one of the ventilator and the air blower is operated.
