## 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

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 2)

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.

### Claim 4 (depends on 2)

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.

### Claim 5 (depends on 2)

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.

### Claim 6 (depends on 1)

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.

### Claim 7 (depends on 1)
