Abstract

A metering system for measuring the electrical power used to charge a vehicle is provided. The metering system includes an electrical meter operably coupled to a conductor connected to the vehicle and an electrical outlet. A controller receives signals from the meter to record the measured electrical consumption. The controller includes a plurality of communications devices for communicating with different communications carriers. In one embodiment, the controller selects one of the communications devices based on availability and a desired criterion. The selected communications device then transmits the measured electrical power consumption to a utility provider. In one embodiment, the metering system is mobile.

Claims

1. An electrical metering device comprising:

an electrical power input;

an electrical power output electrically coupled to said input, said output being adapted to operably couple with a vehicle;

a meter operably coupled between said input and said output;

a controller electrically coupled to said meter;

a first communications device electrically coupled to said controller, said first communications device being adapted to transmit data using a first wireless carrier;

a second communications device electrically coupled to said controller, said second communications device being adapted to transmit data using a second wireless carrier;

a memory device electrically coupled to said meter;

a housing sized to fit in a trunk of a vehicle, wherein said meter, said controller, said memory device, said first communications device and said second communications device are mounted within said housing;

wherein said controller includes a processor responsive to executable computer instructions for storing data indicative of electrical power consumption by said vehicle in said memory device in response to a first signal from said meter, said processor being further responsive to executable computer instructions to determine when said first wireless carrier and said second wireless carrier is available and selecting one of said first communications device or said second communications device in response to receiving a signal from said meter, and wherein said processor is further responsive to executable computer instructions for determining if said first wireless carrier is available and retrieving an electrical consumption data from said memory device and transmitting a second signal indicating said electrical consumption data in response to said first wireless carrier being available.

2. The electrical metering device of claim 1 wherein said first wireless carrier is a radio frequency carrier and said second wireless carrier is a cellular carrier.

3. The electrical metering device of claim 1 wherein said first wireless carrier is selected from a group comprising:

radio frequency, satellite, CDMA cellular and GSM cellular.

4. The electrical metering device of claim 2 wherein said first communications device uses an IEEE 802.11 protocol, IEEE 802.15.4 protocol or IEEE 802.15.1 protocol.

5. The electrical metering device of claim 2 wherein said radio frequency carrier operates in a frequency band of 30 kHz to 40 GHz.
