Vehicular battery charger, charging system, and method with in-vehicle display of charge time
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.
1. A vehicle charger for charging a battery of a vehicle, the vehicle charger comprising:
a display mounted within the vehicle; and
a controller onboard the vehicle and coupled to the display, the controller configured to
begin an active charging session of the battery based on a programmed manner of charge and at least one condition, the programmed manner of charge starting charging of the battery in response to the at least one condition being met,
calculate an amount of time required to charge the battery,
display, during the active charging session but before starting charging of the battery according to the at least one condition, the amount of time upon the display, and
repeatedly update the amount of time upon the display during the active charging session, including during the active charging session but before starting charging of the battery according to the at least one condition.
2. The vehicle charger of claim 1 , wherein the controller is a first controller, the vehicle charger further comprising a receiver coupled to the first controller, the receiver configured to establish communication between the first controller and a second controller remote from the vehicle and the vehicle charger.
3. The vehicle charger of claim 2 , wherein the first controller is further configured to control power supply to the battery of the vehicle responsive at least in part to data received from the second controller via the receiver.
4. The vehicle charger of claim 2 , wherein the first controller is further configured to receive the at least one condition from the second controller via the receiver.
5. The vehicle charger of claim 2 , wherein the first controller is further configured to supply power to the battery of the vehicle based at least in part upon data indicative of a cost of power received from the second controller via the receiver.
6. The vehicle charger of claim 1 , wherein the controller is further configured to display, during the active charging session, a level of charge of the battery on the display.
7. The vehicle charger of claim 1 , further comprising a user interface positioned within the vehicle, wherein the at least one condition includes a time of day and wherein the controller receives the time of day via the user interface.
8. The vehicle charger of claim 7 , wherein the user interface is defined at least in part by the display.
9. A method of charging a battery of a vehicle with a vehicle charger, the method comprising:
beginning an active charging session of the battery based on a programmed manner of charge and at least one condition, the programmed manner of charge starting charging of the battery in response to the at least one condition being met;
calculating, via a controller of the vehicle, an amount of time required to charge the battery;
displaying, during the active charging session but before starting charging of the battery according to the at least one condition, the amount of time upon a display mounted within the vehicle;
supplying, under control of the controller of the vehicle, power to the battery of the vehicle to charge the battery; and
updating the amount of time upon the display during the active charging session, repeatedly update the amount of time upon the display during the active charging session, including during the active charging session but before starting charging of the battery according to the at least one condition.
10. The method of claim 9 , further comprising:
establishing wireless communication between the controller of the vehicle and another controller remote from the vehicle and the vehicle charger; and
starting or stopping supply of power to the battery based at least in part upon a signal received by the controller of the vehicle from the controller remote from the vehicle and the vehicle charger.
11. The method of claim 10 , wherein the signal includes data indicative of a cost of power.
12. The method of claim 9 , further comprising displaying on the display a level of charge of the battery.
13. The method of claim 9 , wherein the at least one condition includes a time of day and further comprising receiving, via a user interface of the vehicle charger, the time of day.
14. The method of claim 13 , wherein the user interface is defined at least in part by the display.
15. A vehicle charger for charging a battery of a vehicle, the vehicle charger comprising:
a display mounted within the vehicle;
a controller onboard the vehicle and coupled to the display, the controller configured to
begin an active charging session of the battery based on a programmed manner of charge and at least one condition, the programmed manner of charge starting charging of the battery in response to the at least one condition being met,
calculate an amount of time required to charge the battery, and
display, during the active charging session but before starting charging of the battery according to the at least one condition, the amount of time upon the display; and
a receiver electrically coupled to the controller;
wherein the controller onboard the vehicle is further configured to repeatedly update the amount of time upon the display during the active charging session, and
wherein the controller onboard the vehicle is further configured to, responsive to data received from another controller remote from the vehicle and the vehicle charger via the receiver, to change a charging state of the vehicle charger by at least one of a group consisting of increasing a rate of charge of the battery, decreasing a rate of charge of the battery, starting battery charging, or stopping battery charging.
16. The vehicle charger of claim 15 , wherein the controller onboard the vehicle is further configured to display a level of charge of the battery on the display during the active charging session.
17. The vehicle charger of claim 15 , further comprising a user interface positioned within the vehicle, wherein the at least one condition includes a time of day and wherein the controller receives the time of day via the user interface.
18. The vehicle charger of claim 17 , wherein the user interface is defined at least in part by the display.
19. The vehicle charger of claim 15 , wherein the controller onboard the vehicle is further configured to supply power to the battery of the vehicle based at least in part upon data indicative of a cost of power received from the controller remote from the vehicle and the vehicle charger via the receiver.
20. The vehicle charger of claim 15 , further comprising a user interface for receiving an input from a user, wherein the controller is configured to receive the input and stop charging of the battery during the active charging session responsive to the input.
