An autonomous underwater vehicle (AUV) including a hydrogen fuel cell is provided. The fuel cell control computer is a separate, stand-alone control system that interfaces with a vehicle control computer (VCC) to ensure safe operation of the fuel cell system. Relay logic for disabling the fuel cell enables the VCC to determine if the fuel cell has shut down, ensuring that the AUV system does not send power to the fuel cell system if there are unsafe conditions.

A method for electrically charging an energy storage of a motor vehicle at an electrical energy source external to the vehicle from a specific initial charge state of the energy storage to a specific final charge state of the energy storage. A control device controls the charging according to the first charging mode such that the energy storage is charged by the external energy source with a first charging power and according to a first overall efficiency. In addition, the control device determines whether an activation request made by a user to activate a second charging mode, which represents an energy saving mode, has been received, and at least if this is the case, the control device controls the charging process according to a second charging mode.

It analyzes the impact of the vehicle user's usage on the performance of the rotary transformer, thereby accurately predicting the remaining service life of the rotary transformer and providing timely fault warnings to the vehicle user.

A server system receives, from an electric vehicle charging station, an identifier of a vehicle that has been plugged into the electric vehicle charging station (EVCS). In response to receiving the identification of the vehicle, the server system performs a lookup of the identification of the vehicle to determine that a first user is associated with the identification of the vehicle and determines whether the first user is within a predefined area relative to the EVCS. In accordance with a determination that the first user is within the predefined area relative to the EVCS, the server system transmits, to the EVCS, an instruction to initiate an operation at the EVCS.

A processor-implemented method includes (i) authenticating a first user at an EV charger application on the first user device, where the application stores authentication data received via the internet, (ii) initiating a first charging session at a charger device with session information data packet including assigning a session identifier and transmitting a user identifier from the first user device via wireless communication, (iii) storing (a) an initial reading of an energy meter and (b) updated readings throughout the session, (iv) terminating the session and storing the final updated reading as part of the completed session information, (v) transferring the completed session information from the charger device to the second user device upon initiating a second session, (vi) upon detecting internet connectivity, transmitting the session information to a cloud service.

Systems, methods, devices, and models for range estimation and analysis in battery powered vehicles are described. Energy consumption over vehicle trips is collected, to evaluate weighting factors for a weighted sum. The weighted sum is evaluated based on determined weighting factors and expected trip data, to determine an energy consumption of a trip or trips of a vehicle. Determined energy consumption for trips is used for evaluating suitability of the vehicle for performing the trips.

Control method for an electric road vehicle comprising the steps of: defining a plurality of virtual gears, each of which determines a respective torque limit profile deliverable by the power train system to the wheels as the velocity varies; detecting, upon actuation of an interface system by the driver, while driving, a selection for one of the virtual gears currently set by the driver; and delivering a drive torque to the at least two wheels as a function of said selection; wherein at least one profile of the plurality of virtual gear profiles comprises an angular point at which, as the velocity of the road vehicle increases, the torque delivered to the wheels is at least partially cut off.
