Charging of a fleet of electric vehicles
First Claim
1. A method for controlling the charging of multiple electric vehicles operating in a geographic area using a control system, the geographic area including one or more charging stations configured to charge the multiple electric vehicles, comprising:
- inputting a tariff schedule into the control system, the tariff schedule identifying the cost of energy at different times in the geographic area;
receiving, using the control system, data from each electric vehicle of the multiple electric vehicles, the multiple electric vehicles including (i) at least one electric vehicle coupled to a charging station of the multiple charging stations and (ii) at least one electric vehicle not coupled to a charging station of the multiple charging stations, the data including at least a state of charge of the vehicle; and
sending instructions from the control system to at least one vehicle of the multiple electric vehicles or at least one charging station of the one or more charging stations, the instructions including at least an amount of energy to transfer to the at least one vehicle based at least on (a) the tariff schedule and (b) the state of charge of each vehicle of the multiple electric vehicles, wherein the sending instructions include sending instructions to the at least one charging station to charge the at least one vehicle using at least a portion of energy stored in an energy storage device.

Abstract
A method for controlling the charging of multiple electric vehicles operating in a geographic area may include inputting a tariff schedule into a control system. The tariff schedule may identify the cost of energy at different times in the geographic area. The method may also include receiving data from the multiple electric vehicles. The data may include at least the state of charge of the vehicle. The method may further include sending instructions to at least one vehicle of the multiple electric vehicles. The instructions may include directives on charging based at least on the tariff schedule and the received data.

9. A method of controlling the charging of a fleet of electric buses operating in a geographic area using a control system, the geographic area including one or more charging stations configured to charge the fleet of electric buses, comprising:
-
inputting a tariff schedule into the control system, the tariff schedule identifying the cost of energy at different times; receiving, using the control system, data from each bus of a plurality of electric buses of the fleet, the plurality of electric buses including (a) at least one bus coupled to a charging station of the one or more charging stations and (b) at least one bus not coupled to a charging station of the one or more charging stations, the data including at least a state of charge of the bus; receiving, using the control system, data related to charging from the one or more charging stations; and sending instructions from the control system to the at least one bus coupled to the charging station or a charging station that the at least one bus is coupled with, the instructions including an amount of energy to transfer to the at least one bus based on at least (a) the tariff schedule and (b) the state of charge of each electric bus of the plurality of electric buses, and a rate of energy transfer to the at least one bus. - View Dependent Claims (10, 11, 12, 13, 14)

15. A control system for controlling the charging of a fleet of electric vehicles operating in a geographic area, the geographic area including one or more charging stations configured to charge the fleet of electric vehicles, comprising:
-
a computer system configured to receive a tariff schedule, the tariff schedule identifying the cost of energy at different times in the geographic area; a receiver configured to receive data related to a state of charge from multiple electric vehicles of the fleet of electric vehicles, the multiple electric vehicles including (i) at least one vehicle coupled to a charging station of the one or more charging stations and (ii) at least one vehicle not coupled to a charging station of the one or more charging stations, wherein the data received from the at least one vehicle not coupled to the charging station includes vehicle identifying information and a current location of the vehicle in the geographic area; and a processor configured to determine an amount of energy to transfer to an electric vehicle of the multiple electric vehicles during charging based on at least (a) the tariff schedule and (b) the state of charge of each electric vehicle of the multiple electric vehicles. - View Dependent Claims (16, 17, 18)
