Abstract

A charger for an electric vehicle is provided. The charge provides for multiple inputs that are combined to provide a single output at higher charging level. The charger includes a toroidal transformer that is electrically coupled between the multiple inputs and the output. The charge may also include a connection to allow an electrical vehicle to communicate with external controllers or servers.

Claims

1. An electric vehicle charger comprising:

a first electrical input, said first electrical input adapted to receive a first electrical power having a first voltage level and a first current level;

a second electrical input, said second electrical input adapted to receive said first electrical power;

a toroidal transformer electrically coupled to said first electrical input and said second electrical input, said toroidal transformer having a first output, wherein said toroidal transformer is adapted to provide a second electrical power having a second voltage level and a second current level to said first output; and

,

a second output configured to electrically couple between a vehicle and said first output.

2. The electric vehicle charger of claim 1 wherein said second voltage level is substantially twice said first voltage level and said second current level is substantially half said first current level.

3. The electric vehicle charger of claim 2 wherein said second output includes a SAE J1772 compliant connector.

4. The electric vehicle charger of claim 1 further comprising a controller operably coupled to said toroidal transformer, wherein said controller limits said second current level in response to a signal.

5. The electric vehicle charger of claim 4 wherein said second output includes a coupler adapted to connect with said vehicle, said coupler having a first conductor electrically coupled to said toroidal transformer and a second conductor operably coupled to said controller.

6. The electric vehicle charger of claim 5 wherein said signal is received by said controller from said second conductor.

7. A device for charging a vehicle at a facility having a first electrical circuit and a second electrical circuit, said device comprising:
