Abstract

To ensure that an energy supply operation can be performed safely and smoothly on a vehicle having a plurality of energy ports such as a charging port, charging ports for supplying electric energy to a high voltage battery and a fuel supply port for supplying fuel to a fuel tank are provided in a vehicle body as energy supply ports. The fuel supply port and charging ports are respectively provided with lid members that are switched between a closed state and an open state by respective lock mechanisms. When closure of one lid member is released, all of the other lid members are prohibited from being switched to the open state, and therefore the number of energy supply ports having an open lid member is limited to one.

Claims

1. An electric vehicle having a plurality of energy supply ports forming a charging port for supplying electric energy to a battery or a fuel supply port for supplying fuel to a fuel tank, lid members for respectively opening and closing said energy supply ports being provided in a vehicle body, said electric vehicle comprising:

a plurality of lock mechanisms for respectively switching said lid members between a closed state and an open state;

opening operation means for releasing closure of said lid member using said lock mechanism; and

opening control means for prohibiting remaining lid members from being switched to the open state when closure of one of said lid members has been released,

wherein, of said plurality of energy supply ports, the number of said energy supply ports simultaneously having an open lid member is limited to one.

2. The electric vehicle according to claim 1, wherein said charging port and said fuel supply port are provided in said vehicle body,

said opening operation means for releasing the closed state of said lid member provided on said fuel supply port is provided in a vehicle cabin, and

said opening control means switch said lock mechanism to the open state when a closure release operation is performed on said lid member of said charging port from a vehicle exterior, whereby said fuel supply port is opened from a vehicle interior and said charging port is opened from said vehicle exterior.

3. The electric vehicle according to claim 1, wherein at least one of said plurality of energy supply ports is a charging port,

said lid member of said charging port is opened when said lid member is pushed inward, and

said lid member is held in the closed state by performing an operation to push said lid member inward from the open state.

4. The electric vehicle according to claim 1, comprising a receiver for receiving a signal from a transmitter held by a passenger and transmitting said received signal to said opening control means,

wherein opening of said lid member is permitted only when said transmitter is within a signal reception area of said receiver.
