Abstract

Some example embodiments include a method for recharging a number of battery electric vehicles. The method include receiving (by a control module configured to control an electrical grid system that include a number of recharging stations that are configured to recharge the number of battery electric vehicles and from the number of battery electric vehicles) usage data that comprises a current charge level, a current location, and a planned itinerary that includes a destination. The method includes determining anticipated electrical loads in the number of sectors of the electrical grid system based on the usage data of the number of battery electric vehicles. The method also includes redistributing the electrical supply on the electrical grid system to at least one recharging station of the number of recharging stations based on the anticipated electrical loads, prior to actual usage defined by the usage data by the number of battery electrical vehicles.

Claims

1. A method for recharging a number of battery electric vehicles, the method comprising:

receiving, by a control module configured to control an electrical grid system that include a number of recharging stations that are configured to recharge the number of battery electric vehicles, from the number of battery electric vehicles, usage data that comprises a current charge level, a current location, and a planned itinerary that includes a destination;

determining, by the control module, anticipated electrical loads in a number of sectors of the electrical grid system based on the usage data of the number of battery electric vehicles;

redistributing, by a power generator in response to receiving a communication including the anticipated electrical loads from the control module in a remote server, an electrical supply on the electrical grid system to at least one recharging station of the number of recharging stations based on the anticipated electrical loads, prior to actual usage defined by the usage data by the number of battery electrical vehicles; and

transmitting, by the control module, to at least one battery electric vehicle of the number of battery electric vehicles, a recommended recharging station among the number of recharging stations for the actual usage by the at least one battery electric vehicle, wherein the actual usage of the recommended recharging station by the at least one battery electric vehicle provides a more even distribution of the anticipated electrical loads on the electrical grid system than the actual usage of a closest recharging station among the number of recharging stations that is closest to the current location, wherein the recommended recharging station has more recharge capacity than the closest recharging station that is closest to the current location of the at least one battery electric vehicle.

2. The method of claim 1, further comprising dynamically varying charge rates for recharging at the number of recharging stations based on the anticipated electrical loads, wherein the charge rates are variable across the number of recharging stations.

3. The method of claim 2, further comprising:

determining, by the control module, an anticipated charge rate for recharging at the number of recharging stations for the at least one battery electric vehicle for the planned itinerary for the at least one battery electric vehicle, wherein the anticipated charge rate is based on the charge rates being dynamically varied based on the anticipated electrical loads; and

transmitting the anticipated charge rate to at least one of a device of the at least one battery electric vehicle and a mobile device associated with an operator of the at least one battery electric vehicle.

4. The method of claim 1, wherein the recommended recharging station provided by the control module is based on an environmental condition that comprises at least one of traffic, geographical terrain, and weather.

5. The method of claim 1, wherein recommendation of the recommended recharging station is derived from at least one of cost, recharge time, and environmental impact.

6. The method of claim 1, further comprising:

receiving, through a network communication by the control module, an electronic token from at least one of a mobile device of an operator of at least one battery electric vehicle of the number of battery electric vehicles and a device associated with the at least one battery electric vehicle; and

responsive to receiving the electronic token, reserving a reserve spot at the number of recharging stations to recharge the at least one battery electric vehicle, wherein the reserving of the reserve spot is for a guaranteed time period based on a monetary value of the electronic token and is unrestricted with regard to a recharging station of the number of recharging stations where the reserve spot is located, wherein the reserving of the reserve spot is unrestricted with regard to a time and a day.
