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 within view of a user seated in the vehicle; and
a controller onboard the vehicle and coupled to the display, the controller configured to
receive a selection of a programmed manner of charge of the battery, the programmed manner of charge starting charging of the battery in response to at least one condition being met,
begin an active charging session based on the programmed manner of charge and the at least one condition,
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 calculated amount of time upon the display simultaneously with an input mechanism to start a manual charge of the battery, and
repeatedly update the time upon the display during the course of the active charging session.
2. The vehicle charger of claim 1 , wherein the controller is a first controller, the vehicle charger further comprising a receiver enabling 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 configured to control power supply to the battery of the vehicle responsive at least in part to signals from the second controller.
4. The vehicle charger of claim 1 , wherein the controller is also further configured to simultaneously display a level of charge of the battery and the calculated amount of time on the display.
5. The vehicle charger of claim 1 , further comprising a user interface in the vehicle and within reach of the user seated within the vehicle, and by which the user enters a time of day, wherein the controller is further configured to supply power to the battery of the vehicle based at least in part upon the time of day entered by the user.
6. The vehicle charger of claim 5 , wherein the user interface is defined at least in part by the display.
7. The vehicle charger of claim 2 , wherein the controller is further configured to supply power to the battery of the vehicle based at least in part upon cost of power information received by the vehicle charger from the second controller via the receiver.
8. A method of charging a battery of a vehicle, the method comprising:
connecting a vehicular battery charger onboard the vehicle to a source of power;
receiving a selection of a programmed manner of charge of the battery, the programmed manner of charge starting charging of the battery in response to at least one condition being met beginning an active charging session based on the programmed manner of charge and the at least one condition;
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 the display of the vehicle simultaneously with an input mechanism to start a manual charge of the battery, the display of the vehicle within reach of a user seated 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 course of the active charging session.
9. The method of claim 8 , further comprising:
establishing wireless communication between the controller of the vehicle and another controller remote from the vehicle and the vehicular battery charger; and
starting or stopping supply of power to the battery based at least in part upon a signal received from the controller remote from the vehicle to the controller of the vehicle.
10. The method of claim 8 , further comprising displaying on the display a level of charge of the battery simultaneously with the amount of time.
11. The method of claim 8 , further comprising:
receiving, via a user interface of the vehicular battery charger, a time of day; and
supplying power to the battery based at least in part upon the time of day.
12. The method of claim 11 , wherein the user interface is defined at least in part by the display.
13. The method of claim 9 , wherein the signal includes data indicative of a cost of power.
14. A vehicle charger for charging a battery of a vehicle, the vehicle charger comprising:
a display mounted within the vehicle and within view of a user seated in the vehicle;
a controller onboard the vehicle and coupled to the display, the controller configured to
receive a selection of a programmed manner of charge of the battery, the programmed manner of charge starting charging of the battery in response to at least one condition being met,
begin an active charging session based on the programmed manner of charge and the at least one condition,
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 calculated amount of time upon the display simultaneously with an input mechanism to start a manual charge of the battery; and
a receiver electrically coupled to the controller;
wherein the controller is further configured to repeatedly update the time upon the display during the course of the active charging session,
wherein the controller onboard the vehicle is further configured, responsive to signals received from another controller remote from the vehicle and the vehicular battery 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.
15. The vehicle charger of claim 14 , wherein the controller onboard the vehicle is further configured to simultaneously display a level of charge of the battery and the calculated amount of time on the display.
16. The vehicle charger of claim 14 , further comprising a user interface in the vehicle and within reach of the user seated within the vehicle, and by which the user enters a time of day, wherein the controller is further configured to supply power to the battery of the vehicle based at least in part upon the time of day entered by the user.
17. The vehicle charger of claim 16 , wherein the user interface is defined at least in part by the display.
18. The vehicle charger of claim 14 , wherein the controller onboard the vehicle is further configured to supply power to the battery of the vehicle based at least in part upon cost of power information received by the vehicle charger from the controller remote from the vehicle and the vehicular battery charger via the receiver.
19. The vehicle charger of claim 14 , wherein the signals are wireless signals.
