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.
Claims21
A vehicle charger for charging a battery of a vehicle, the vehicle charger comprising:
- an electrical power cord releasably attachable to at least one of the vehicle and a source of power;
- a controller;
- and
- a display coupled to the controller;
- wherein the controller is configured to:
- detect a level of charge of the battery;
- determine a first charging parameter of the vehicular charger to be used in charging the battery based on a first selection received through a user-manipulatable control coupled to the controller, the first charging parameter comprising at least one of a group consisting of a voltage and an amperage;
- calculate a first amount of time needed to charge the battery based at least in part upon the level of charge of the battery and the first charging parameter;
- display the first amount of time needed to charge the battery on the display;
- determine a second charging parameter of the vehicular charger to be used in charging the battery based on a second selection received through the user-manipulatable control coupled to the controller, the second charging parameter comprising at least one of a group consisting of a voltage and an amperage;
- calculate a second amount of time needed to charge the battery based at least in part upon the second charging parameter;
- and
- display the second amount of time needed to charge the battery on the display;
- start charging the battery according to the second charging parameter.

A method of charging a battery of a vehicle, the method comprising:
- establishing an electrical connection between a plug at a terminal end of an electrical charging cord and the vehicle;
- supplying power to the vehicle via the electrical charging cord and the plug;
- detecting, with a controller, a level of charge of the battery;
- determining with the controller, at least one charging parameter of the vehicular charger to be used in charging the battery, the at least one charging parameter comprising at least one of a group consisting of a voltage and an amperage;
- calculating, with the controller, an amount of time needed to charge the battery based at least in part upon the level of charge of the battery and the at least one charging parameter;
- displaying, with the controller, the amount of time needed to charge the battery on the display;
- wirelessly transmitting the amount of time needed to charge the battery to another controller remote from the vehicle and the battery for display to a user of the other controller;
- and
- in response to receiving a signal from the user via the other controller during an active charging session, changing a charging state of the battery.

A vehicle charger for charging a battery of a vehicle, the vehicle charger comprising:
- an electrical power cord releasably attachable to at least one of the vehicle and a source of power;
- a first controller;
- and
- a transmitter coupled to the first controller;
- wherein the first controller is configured to:
- detect a level of charge of the battery;
- determine a least one charging parameter of the vehicular charger to be used in charging the battery, the at least one charging parameter comprising at least one of a group consisting of a voltage and an amperage;
- calculate an amount of time needed to charge the battery based at least in part upon the level of charge of the battery and the at least one charging parameter;
- wirelessly transmit data indicative of the calculated amount of time needed to charge the battery to a second controller remote from the vehicle charger for display to a user of the second controller;
- and
- in response to receiving a signal from the user via the second controller during an active charging session, change a charging state of the battery.
