Abstract

A vehicle battery charger and a vehicle battery charging system are described and illustrated, and can include a controller enabling a user to enter a time of day at which the vehicle battery charger or system begins and/or ends charging of the vehicle battery. The vehicle battery charger can be separate from the vehicle, can be at least partially integrated into the vehicle, can include a transmitter and/or a receiver capable of communication with a controller that is remote from the vehicle and vehicle charger, and can be controlled by a user or another party (e.g., a power utility) to control battery charging based upon a time of day, cost of power, or other factors.

Claims

1. A vehicle charger for charging a battery of a vehicle, the vehicle charger adapted for communication with a first controller remote from the vehicle and vehicle charger, the vehicle charger adapted for wireless communication with a second controller remote from the vehicle and the vehicle charger, the second controller associated with a computer, the vehicle charger comprising:

an electrical power cord releasably attachable to at least one of the vehicle and a source of power;

a third controller electrically coupled to the electrical power cord;

at least one of a transmitter and a receiver coupled to the third controller and adapted for communication with the first controller and the second controller,

wherein the third controller is responsive to at least one signal from the first controller by automatically changing a charging state of the vehicle charger at a time associated with a cost of power to the battery reaching a threshold cost of power to the battery, the at least one signal related to a cost of electrical power, changing the charging state of the vehicle charger including automatically starting charging when the cost of electrical power is equal to or less than the threshold cost of power,

wherein the third controller is responsive to at least one signal from the second controller by changing a charging state of the vehicle charger to start charging, the at least one signal from the second controller being received by the third controller in response to a user selecting a user-manipulable control on a screen associated with the second controller, and

wherein the user-manipulatable control is operable by the user to start a manual charge of the battery or enter at least one of a group consisting of a time of day by which the battery must be charged and a command to delay charging of the battery by the vehicle charger.

2. The vehicle charger of claim 1, wherein the third controller is adapted for automatic establishment of communication with the first controller upon connection of the vehicle charger with at least one of the battery and the source of power.

3. The vehicle charger of claim 1, further comprising a display coupled to the third controller, the display displaying a level of charge of the battery.

4. The vehicle charger of claim 1, further comprising a display coupled to the third controller, the display displaying an amount of time for the battery to be fully charged based upon information regarding the battery received by the third controller.

5. The vehicle charger of claim 1, further comprising a display displaying a total power cost of a charging session.

6. The vehicle charger of claim 1, wherein the third controller automatically changes the charging state of the vehicle charger based at least in part upon a time of day.

7. The vehicle charger of claim 1, further comprising a battery of the vehicle charger, the battery of the vehicle charger coupled to the third controller and the electrical power cord, and supplying power to charge the battery of the vehicle in at least one state of the vehicle charger.

8. A vehicle charger for charging a battery of a vehicle in the course of a charging session, the vehicle charger adapted for wireless communication with a computer remote from the vehicle and vehicle charger, the computer including a remote controller, the vehicle charger comprising:

a controller;

a display coupled to the controller and adapted to display a time; and

a user-manipulatable control coupled to the controller and operable by a user to enter a time of day at which the charging session will end,

wherein the controller automatically changes the supply of electric power to the vehicle battery during the course of the charging session by at least one of a group consisting of increasing a rate of charge of the battery, decreasing the rate of charge of the battery, starting battery charging, and stopping battery charging based at least in part upon the time needed to charge the vehicle battery by the time of day entered by the user,

wherein the controller automatically changes the supply of electric power to the vehicle battery at a time associated with a cost of power to the battery reaching a threshold cost of power to the battery, wherein changing the charging state of the vehicle charger includes automatically starting charging when the cost of power to the battery is equal to or less than the threshold cost of power, and

wherein the controller is responsive to at least one signal from the remote controller by changing the supply of electric power to the vehicle battery to start charging, the at least one signal from the remote controller being received by the controller in response to a user selecting a second user-manipulable control on a screen associated with the remote controller.

9. The vehicle charger of claim 8, wherein the display is mounted in a console within the vehicle.

a user-manipulatable control within reach of the user seated within the vehicle and by which a user can enter a time of day; and

a controller coupled to the display and to the battery, the controller changing a supply of electric power to charge the battery during the course of a charging session by at least one of a group consisting of increasing a rate of charge of the battery, decreasing the rate of charge of the battery, starting battery charging, and stopping battery charging based at least in part upon the time of day entered by the user,

wherein the controller supplies electric power to the battery if a level of battery charge is below a threshold level of battery charge independent of the time of day entered by the user, the controller supplying electric power to the battery at least until the threshold level of battery charge is reached,

wherein the controller automatically starts battery charging when a cost of electrical power to the battery is equal to or less than a threshold cost of power to the battery, and

wherein the controller is responsive to at least one signal from the remote controller by changing the supply of electric power to the vehicle battery to start charging, the at least one signal from the remote controller being received by the controller in response to a user selecting a second user-manipulable control on a screen associated with the remote controller.
