A method for propelling of a vehicle comprising a power train with an electric motor connected to a location in the vehicle intended for mounting of an energy supply unit intended for driving of the electric motor during normal operating conditions of the vehicle is described. The method comprises the steps of: connecting an electric power source to a power connection element mounted on the vehicle and being connected to the electric motor and to the location, disconnecting the location in order to accomplish a direct connection between the power connection element and the electric motor and propelling the vehicle by means of the electric motor powered by electricity from the electric power source. A method for manufacturing of a vehicle comprising a power train with an electric motor and a vehicle comprising a power train with an electric motor are also described herein.

Provided is a bootstrap method for registering a charging station (CS), which was in an offline state, to an electric vehicle charging station management system (CSMS) and operating same. The bootstrap method comprises the steps of: storing at least partial bootstrap information in a CS so as to configure bootstrap information; connecting the CS to a CSMS by setting a security channel between the CS and the CSMS for maintaining registration information about the CS; and registering the CS to the CSMS.

Embodiments described herein relate to predicting the utilization of electric vehicle (EV) charge points. Methods may include: receiving an indication of a plurality of candidate locations for EV charge points; determining static map features of the plurality of candidate locations; inputting the plurality of candidate locations and static map features into a machine learning model, where the machine learning model is trained on existing EV charge point locations, existing EV charge point static map features, and existing EV charge point utilization; determining, based on the machine learning model, a predicted utilization of an EV charge point at the plurality of candidate locations; and generating a representation of a map including the plurality of candidate locations, where candidate locations of the plurality of candidate locations are visually distinguished based on a respective predicted utilization of an EV charge point at the candidate locations.

An electronic control unit (ECU) controls a vehicle capable of externally discharging an electric power via a discharge connector. The vehicle includes: an on-board inverter that adjusts the voltage of an alternating current (AC) power; and a vehicle inlet that discharges to the discharge connector the AC power output from the power converter when the discharge connector is connected to the vehicle inlet. The vehicle inlet has a CP terminal through which a control pilot (CPLT) signal is transmitted when the vehicle 1 is charged externally. The ECU includes a processor. The processor determines the voltage of the AC power output from the on-board inverter, based on the voltage of the CP terminal.

A port for electric vehicles includes an off-loading zone for off-loading one or more passengers from an electric vehicle; a loading zone for loading one or more passengers onto the electric vehicle; and a charging zone for charging the electric vehicle while the electric vehicle is moving from the off-loading zone to the loading zone.

A system comprises a computer having a processor and a memory, the memory storing instructions executable by the processor to receive, from a charge-requesting vehicle, a charge request, determine a suggested provider pool for fulfilling the charge request, the suggested provider pool including multiple suggested charge-providing vehicles, send suggested provider data to the charge-requesting vehicle, the suggested provider data identifying the multiple suggested charge-providing vehicles, receive, from the charge-requesting vehicle, a provider selection identifying one of the multiple suggested charge-providing vehicles as a selected charge-providing vehicle, identify transfer parameters for a battery charge transfer from the selected charge-providing vehicle to the charge-requesting vehicle; and send a transfer initiation message to instruct the selected charge-providing vehicle to initiate the battery charge transfer according to the transfer parameters.

A light rail transit system has a railcar having a roller coaster wheel assembly, solar panels, a battery bank, an inverter, a solar charge controller, and a power rail contactor. The light rail system further has a rail system having a first riding rail and a second riding rail for receiving the roller coaster wheel assembly, and a power rail for providing backup power to the railcar via the power contactor, the power rail extending less than the length of the first riding rail and second riding rail and only supplying current when the power rail contactor of the railcar is in contact therewith.
