Communication systems and methods for hydrogen fueling and electric charging
Systems and methods for fueling (or charging) communication, for example between a hydrogen fueling station and a hydrogen powered vehicle (or an electric vehicle and charging station) may utilize near field communication as well as vehicle to infrastructure communication. Safety information, fueling or charging information, payment information, and other information may be transmitted, and the redundant nature of the communication permits fault recovery and improved process monitoring. In this manner, fueling and/or recharging is made safer, faster, and more efficient.
1. A method for communication between a charging station and an electric vehicle, the method comprising:
disposing a charging cable of the station within a specified distance of a receptacle on the vehicle to establish, via first near field communication (NFC) hardware disposed proximate the nozzle and second NFC hardware disposed proximate the receptacle, an NFC link therebetween;
communicating to the station, via the NFC link, identifying information for the vehicle;
selecting, by the station and after establishing the NFC link, a vehicle to infrastructure (V2X) communication network based on the identifying information for the vehicle;
establishing, between the station and the vehicle, a V2X communication link via the V2X communication network;
delivering through the charging cable, by the station and to the vehicle via the receptacle, electrical current to at least partially charge an electric vehicle battery; and
monitoring, via the V2X communication network and during the delivering electric current, one or more status indicators for the electric vehicle battery.
2. The method of claim 1 , further comprising stopping, by the station, delivery of electric current to the vehicle in response to an indication that a vehicle battery condition is out of bounds.
3. The method of claim 1 , further comprising communicating, via the NFC link, one or more of: a charging protocol identifier; a vehicle identification number, battery capacity, battery type, receptacle type, a charging command, a measured temperature for the electric vehicle battery, a measured voltage for the electric vehicle battery, a maximum current between the charging cable and the receptacle, or a watchdog counter.
4. The method of claim 1 , further comprising transmitting to the vehicle, by the station and over the V2X communication link, an update to at least one of: a software application operative on the vehicle; or firmware for an electronic device operative as part of the vehicle.
5. The method of claim 1 , further comprising exchanging, between the station and the vehicle and over the V2X communication link, payment information and confirmation associated with the delivering the electric current to the vehicle.
6. The method of claim 1 , further comprising downloading from the vehicle, to the station and over the V2X communication link, diagnostic information for a component of the vehicle.
7. The method of claim 1 , further comprising, responsive to an interruption in communication over one of the V2X communication link or the NFC link, completing delivery of electric current the charging cable in accordance with a default charging protocol associated with the electric vehicle battery.
8. The method of claim 1 , further comprising updating, responsive to the monitoring and in a database accessible to the station, at least one characteristic of a default charging protocol for the vehicle.
9. The method of claim 1 , wherein a communication protocol of the V2X communication link comprises at least one of an IEEE 802.11 protocol, a 4G LTE mobile network protocol, or a 5G mobile network protocol.
10. The method of claim 1 , wherein the first NFC hardware is replaceable without impairing the electric current delivery function of the charging cable.
11. The method of claim 1 , wherein the specified distance is 20 centimeters or less.
12. The method of claim 1 , wherein the charging station is also a hydrogen fueling station, wherein the electric vehicle is also a hydrogen powered vehicle, and wherein the method further comprises:
disposing a nozzle of the station within a specified distance of a receptacle on the vehicle to establish, via third NFC hardware disposed proximate the nozzle and fourth NFC hardware disposed proximate the receptacle, a second NFC link therebetween; and
delivering through the nozzle, by the station and to the vehicle via the receptacle, pressurized hydrogen to at least partially fill a vehicle hydrogen tank.
13. The method of claim 12 , further comprising monitoring, during the delivering pressurized hydrogen and via the second NFC link, one or more status indicators for the vehicle hydrogen tank.
14. The method of claim 1 , further comprising bringing a third NFC device associated with an operator of the vehicle into proximity with fourth NFC hardware disposed on the charging station to establish a second NFC link therebetween.
15. The method of claim 14 , further comprising conducting, using information transmitted via the second NFC link, a payment transaction for charging the vehicle.
16. The method of claim 14 , further comprising conducting, using information transmitted via the second NFC link, a data transaction associated with the vehicle.
17. The method of claim 16 , wherein the data transaction comprises at least one of: redeeming a voucher to at least partially pay for charging of the vehicle; activation of one or more features or capabilities of the charging station, such as infotainment resources, special pricing conditions, or in-store offers at a retail establishment associated with or in physical proximity to the charging station; authentication or authorization for charging of the vehicle to proceed; or service of the charging station by an employee.
