Abstract
This electric power system controller for an automobile secures satisfactory driving control of a vehicle and outputs 100 V AC using electric power from a secondary battery. The stop of the 100 V AC output is determined by a 100 V AC inverter according to a state of the 100 V AC inverter, a vehicle control system, or an AC plug receptacle 50 or a state represented by the temperature, inter-terminal voltage, and remaining capacity SOC of a battery which exchanges electric power with a driving motor (S100 to S109, S114). Further, a charge discharge state is determined from the charging and discharge current and charge and discharge integration amount and the 100 V AC output is limited by the 100 V AC inverter (S108, S110, S116).
Claims30
An electric power system controller which controls an electric power system of an automobile on which a chargeable and dischargeable secondary battery is mounted, comprising:
- an electric power converter which converts an electric power from the secondary battery to predetermined AC power;
- a state detector which detects a state of the secondary battery;
- and
- an electric power conversion limiting unit which limits electric power conversion by the electric power converter according to the detected state of the secondary battery.
An electric power system controller which controls an electric power system of an automobile on which a chargeable and dischargeable secondary battery is mounted, comprising:
- an electric power converter which converts electric power from the secondary battery to predetermined AC power;
- a state detector which detects a state of the power system from the secondary battery to an AC output end;
- and
- an electric power conversion limiting unit which limits the electric power conversion by the power converter according to the detected state of the electric power system.
An electric power system controller that controls an electric power system of an automobile on which a chargeable and dischargeable secondary battery is mounted and which can be driven using the electric power from the secondary battery, comprising:
- an electric power converter which converts electric power from the secondary battery to predetermined AC power;
- a state detector which detects a driving state of the automobile;
- and
- an electric power conversion limiting unit which limits electric power conversion by the electric power converter according to the detected driving state.
An automobile provided with a driving control unit which drives and controls an internal engine and/or an electric motor as a power source, and
