Abstract
A control method, device and system for a vehicle charging port cover, and an electric vehicle. The control method for a vehicle charging port cover is applied to a controller (101) separately connected to a fast charging port cover and a slow charging port cover. The method comprises: acquiring the open/close state of the fast charging port cover and the open/close state of the slow charging port cover (step 201); controlling the slow charging port cover to be in a locked state when the fast charging port cover is determined to be in an open state (step 202); and controlling the fast charging port cover to be in a locked state when the slow charging port cover is determined to be in an open state (step 203).
Claims12
A control method for a vehicle charging port cover, wherein the method is applied to a controller connected to a quick charging port cover and a slow charging port cover, and the method comprises:
- acquiring an open/close state of the quick charging port cover and an open/close state of the slow charging port cover;
- controlling the slow charging port cover to be in a locked state in a case where it is determined that the quick charging port cover is in an open state;
- and
- controlling the quick charging port cover to be in the locked state in a case where it is determined that the slow charging port cover is in the open state;
- wherein the controller is further connected to a first port cover locking unit and a second port cover locking unit, the first port cover locking unit is connected to the quick charging port cover, and the second port cover locking unit is further connected to the slow charging port cover;
- and
- before the step of acquiring an open/close state of the quick charging port cover and an open/close state of the slow charging port cover, the method further comprises:
- sending a first unlocking instruction to the first port cover locking unit and sending a second unlocking instruction to the second port cover locking unit on the condition that a charging port cover unlocking instruction is received;
- and on the condition that the charging port cover unlocking instruction is not received, sending a first locking instruction to the first port cover locking unit and a second locking instruction to the second port cover locking unit, wherein the charging port cover unlocking instruction is used for indicating that currently an electric vehicle is capable of being charged.
A control system for a vehicle charging port cover, wherein the system comprises:
- a controller, and a first port cover sensing unit, a first port cover locking unit, a second port cover sensing unit, and a second port cover locking unit respectively connected to the controller;
- wherein the first port cover sensing unit is connected to a quick charging port cover, and is used for transmitting a first open signal to the controller on the condition that the quick charging port cover is in an open state;
- the first port cover locking unit is connected to the quick charging port cover, and is used for controlling the quick charging port cover to be in a locked state on the condition that a first locking instruction transmitted by the controller is received;
- the second port cover sensing unit is connected to a slow charging port cover, and is used for detecting an open/close state of the slow charging port cover and transmitting the open/close state of the slow charging port cover to the controller;
- the second port cover locking unit is connected to the slow charging port cover, and is used for transmitting a second open signal to the controller on the condition that the slow charging port cover is in an open state;
- and
- the controller is used for transmitting a second locking instruction to the second port cover locking unit on the condition that the first open signal is received, and for transmitting a first locking instruction to the first port cover locking unit on the condition that the second open signal is received;
- wherein the first port cover locking unit comprises a fifth resistor, and a first charging port cover motor connected to the quick charging port cover, wherein the first charging port cover motor is connected in parallel to the fifth resistor, and is used for rotating in a first direction for a specified duration to control the quick charging port cover to be in an unlocked state on the condition that a first unlocking instruction is received, and for rotating in a second direction for a specified duration to control the quick charging port cover to be in a locked state on the condition that the first locking instruction is received, wherein the first direction and the second direction are opposite;
- and
- the second port cover locking unit comprises a sixth resistor, and a second charging port cover motor connected to the slow charging port cover, wherein the second charging port cover motor is connected in parallel to the sixth resistor, and is used for rotating in the first direction for a specified duration to control the slow charging port cover to be in the unlocked state on the condition that a second unlocking instruction is received, and for rotating in the second direction for a specified duration to control the slow charging port cover to be in the locked state on the condition that the second locking instruction is received.
