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 system for charging a battery of a vehicle via a vehicle charger and for communication with a first controller remote from the vehicle charger and the battery, the system comprising: the vehicle charger, the vehicle charger including: a second controller, and a receiver coupled to the second controller; and a third, portable controller external to the vehicle charger and remote from the first controller, wherein the third controller is configured to: receive data indicative of cost of power sent by the first controller, and communicate with the second controller via the receiver included in the vehicle charger to control the vehicle charger. ### Claim 2 (depends on 1) The system of claim 1, wherein the third controller is configured to communicate with the second controller to control the vehicle charger based at least in part on the data indicative of cost of power. ### Claim 3 (depends on 1) The system of claim 1, wherein the third controller is configured to communicate with the second controller to control the vehicle charger by sending at least one signal to the second controller to start charging of the battery during a charging session of the battery. ### Claim 4 (depends on 1) The system of claim 1, wherein the third controller is configured to communicate with the second controller to control the vehicle charger by sending at least one signal to the second controller to stop charging of the battery during a charging session of the battery. ### Claim 5 (depends on 1) The system of claim 1, wherein the third controller is further configured to display, based on the data indicative of cost of power, a cost of power per unit of power on a user interface. ### Claim 6 (depends on 5) The system of claim 5, wherein the third controller is configured to display the cost of power per unit of power while charging of the battery is in progress with the vehicle charger. ### Claim 7 (depends on 5) The system of claim 5, wherein the third controller is further configured to display a level of charge of the battery simultaneously with the cost of power per unit of power. ### Claim 8 (depends on 1) The system of claim 1, wherein the third controller is further configured to display a level of charge of the battery on a display remote from the vehicle and the vehicle charger. ### Claim 9 (depends on 1) The system of claim 1, wherein the second controller is further configured to receive the data indicative of cost of power sent by the first controller. ### Claim 10 (depends on 1) The system of claim 1, wherein the third controller is further configured to simultaneously display a total cost of power supplied to the battery, a cost of power per unit based on the data indicative of cost of power, and a level of charge of the battery upon a display. ### Claim 11 (depends on 10) The system of claim 10, wherein the second controller is further configured to display a calculated amount of time remaining to charge the battery upon the display. ### Claim 12 (depends on 10) The system of claim 10, wherein the display is coupled to the third controller. ### Claim 13 (depends on 1) The system of claim 1, wherein the third controller is further configured to receive, from the first controller, additional data indicative of a new cost of power per unit of power to the vehicle charger and to automatically update a display with the new cost of power per unit of power. ### Claim 14 A method of charging a battery of a vehicle via a vehicular battery charger, the method comprising: receiving, by a first, portable controller remote from the vehicle and the vehicular battery charger, data indicative of cost of power; establishing communication between the first controller and a second controller included in the vehicular battery charger; and transmitting at least one signal from the first controller to the second controller to control the vehicular battery charger. ### Claim 15 (depends on 14) The method of claim 14, wherein receiving the data indicative of cost of power including receiving, by the first controller, the data indicative of cost of power from a third controller remote from the vehicle and the vehicular battery charger. ### Claim 16 (depends on 14) The method of claim 14, wherein transmitting the at least one signal from the first controller to the second controller includes transmitting the at least one signal based at least in part on the data indicative of cost of power. ### Claim 17 (depends on 14) The method of claim 14, wherein transmitting the at least one signal includes transmitting at least one selected from a group consisting of a first signal to start charging of the battery with the vehicular battery charger and a second signal to stop charging of the battery with the vehicular battery charger. ### Claim 18 (depends on 14) The method of claim 14, further comprising displaying, on a display coupled to the first controller while charging of the battery is in progress with the vehicular battery charger, a cost of power per unit of power based on the data indicative of cost of power. ### Claim 19 (depends on 14) The method of claim 14, wherein transmitting the at least one signal from the first controller to the second controller to control the vehicular battery charger includes transmitting a signal based on the data indicative of cost of power. ### Claim 20 (depends on 14) The method of claim 14, wherein the first controller is further configured to receive additional data indicative of a new cost of power per unit of power to the vehicular battery charger and to automatically update a display with the new cost of power per unit of power.
