A communication control device comprises: an antenna; and a control unit that controls wireless communication related to wireless power transfer to a power receiver device through a power transmitter device. The control unit acquires via the antenna a radio wave status of each of a plurality of channels related to the wireless communication. The control unit acquires a power transmission status of the wireless power transfer. The control unit sets, based on the acquired power transmission status, switching conditions for switching the channel according to the radio wave status. The control unit causes the channel to be switched based on the radio wave status and the switching conditions. The control unit causes the wireless communication to continue on the switched channel.

A vehicle includes a motor, an inverter, an inter-line short circuit, an operation circuit, and a harness. The motor is provided in a wheel. The inverter is configured to supply electric power to the motor. The inter-line short circuit is provided in the wheel and configured to cause the motor to be short-circuited when not in operation and couple the motor and the inverter when in operation. The operation circuit is provided in a vehicle body of the vehicle and configured to operate the inter-line short circuit. The harness extends between the wheel and the vehicle body. In the harness, at least one power supply line, which is configured to supply electric power to the motor through the inverter and the inter-line short circuit, and an operation line, which is configured to couple the inter-line short circuit and the operation circuit, are bundled.

There are described herein methods and systems for operating an electric motor of a watercraft. In one method, the electric motor of the watercraft is controlled based on commands received from an accelerator of the watercraft, a sensor signal is received from at least one sensor of the watercraft while the electric motor is in operation, the sensor signal indicative of an undesirable condition of a water intake of the watercraft, and a change is effected to the controlling of the electric motor in response to receiving the sensor signal.

A request to move along a route is detected. The request is from a first electric vehicle. The route may include a start point and an end point. It may be determined that the first vehicle is an electric vehicle including a battery. In response to determining that the first vehicle is an electric vehicle, one or more battery parameters of the first vehicle may be retrieved. One or more electric vehicle chargers may be identified based on the start point and the end point. A subset of the electric vehicle chargers may be selected based on the battery parameters of the first vehicle. A second route is generated based on the subset of the electric vehicle chargers. The second route is generated such that the first vehicle is capable of reaching the end point. The route of the first vehicle may be replaced with the second route.

Systems, apparatus and methods may be configured to implement actively-controlled light emission from a robotic vehicle. A light emitter(s) of the robotic vehicle may be configurable to indicate a direction of travel of the robotic vehicle and/or display information (e.g., a greeting, a notice, a message, a graphic, passenger/customer/client content, vehicle livery, customized livery) using one or more colors of emitted light (e.g., orange for a first direction and purple for a second direction), one or more sequences of emitted light (e.g., a moving image/graphic), or positions of light emitter(s) on the robotic vehicle (e.g., symmetrically positioned light emitters). The robotic vehicle may not have a front or a back (e.g., a trunk/a hood) and may be configured to travel bi-directionally, in a first direction or a second direction (e.g., opposite the first direction), with the direction of travel being indicated by one or more of the light emitters.

A sensor unit includes a current sensor that detects a current, a voltage sensor that detects a voltage, a ground fault sensor that detects a ground fault, and a common substrate on which the current sensor, the voltage sensor, and the ground fault sensor are mounted. In the sensor unit, for example, in a power supply circuit of a vehicle, the three sensors of the high voltage system can be integrated on the common substrate, so that an increase in the number of parts can be suppressed.

A method for controlling a battery charger circuit of a vehicle. The method includes injecting a first current pulse between at least one line and a protective earth connection of the battery charger circuit. The method also includes measuring at least one line voltage value of at least one node of the battery charger circuit. The method also includes identifying a noise value by performing one or more operations on the battery charger circuit. The method also includes determining a protective earth connection impedance based on the at least one line voltage value and the noise value.

The present disclosure relates to a control method for a fuel cell. The control method includes: collecting, by a controller, state information of a fuel cell (FC) stack; determining, by the controller, a degradation state of the FC stack from the collected state information of the FC stack; correcting, by the controller, a basic threshold output corresponding to a present driving state of a vehicle on the basis of information of the determined degradation state of the FC stack; comparing, by the controller, a post-correction threshold output that is obtained by correcting the basic threshold output and a motor demand output, and determining, by the controller, stopping or restarting of a fuel cell; and controlling, by the controller, such that the determined stopping or restarting state of the fuel cell is achieved.

An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.
