A mobile electric vehicle charging system may include a fuel cell configured to generate electric power required to drive a vehicle, a main battery configured to store electric power generated by the fuel cell, a bidirectional power converter configured to control electric power input to and output from the main battery, a mobile charger configured to supply electric power to charge another vehicle, and a high-voltage junction box for divergence, configured to distribute electric power generated by the fuel cell to the bidirectional power converter and the mobile charger.

A computer-implemented method for increasing safety during charging of a vehicle battery of a vehicle by a charging station, the method comprising the steps of calculating a forecast value for a maximum safe charging current by the controller of the vehicle based on sensor data generated by sensors of the vehicle and adjusting the charging current provided by the charging station in response to the forecast value of a maximum safe charging current.

An access control system for electric vehicle charging is provided that includes an access device, a secure reservation interface, a reservation server and a smartphone application installed on the smartphone. The access device includes a short-range wireless communication module connected to a processor having control of an electric vehicle charger. The secure reservation interface receives a reservation request for a reservation at a given destination. The reservation server receives the reservation request for the destination, issues a reservation certificate, and transmits the reservation certificate from the reservation server to a smartphone. The smartphone application has access to a short range wireless communication setting corresponding to the access device. The access device receives the reservation certificate from the smartphone application based on use by the smartphone application of the short-range wireless communication setting. The processor activates the electric vehicle charger based on at least the receipt of the reservation certificate.

A wireless charging system includes a platform having a substantially horizontal upper surface configured to support a vehicle and an induction coil coupled to the platform. The induction coil is configured to receive electrical energy from an energy source and generate a magnetic field above the upper surface, the magnetic field being positioned to wirelessly transfer the electrical energy to the vehicle while the vehicle is positioned atop the platform.

A charging system includes a service vehicle and a controller. The service vehicle includes a chassis, a series of tractive elements coupled to the chassis, an energy storage device, and a charging interface operatively coupled to the energy storage device. The controller is configured to identify a location of a vehicle, control the service vehicle to navigate to the location of the vehicle, and control the service vehicle to transfer energy from the energy storage device to the vehicle through the charging interface.

A method of operating a vehicle fleet includes providing a first vehicle including a first energy storage device and a first wireless charging coil, providing a second vehicle including a second energy storage device and a second wireless charging coil, providing, by an external device, electrical energy to the first vehicle, charging, by the first vehicle, the first energy storage device using a first portion of the electrical energy, transferring, through the first wireless charging coil and the second wireless charging coil, a second portion of the electrical energy to the second vehicle, and charging, by the second vehicle, the second energy storage device using the second portion of the electrical energy.
