A system for the supplemental generation of energy from the operation of a vehicle operation, and specifically to the generation of energy in connection with a vehicle's drum brakes in combination with brushless electric motor-generators. The system includes a rotational conveyor that operatively connects the drum to a coupler member attached to a generator so that rotation of the drum rotates the coupler member to create energy. A frame member may position and retain the generator in place relative to the drum.

A road-guided motor vehicle includes a power collector for an overhead line and an actuator arrangement. The power collector is controlled by the actuator arrangement from a first, pantograph-lowered into a second, pantograph-raised position or vice versa. The power collector is assigned a sensor arrangement having a data connection to a control unit of the actuator arrangement. The control unit is configured such that a contact pressure of power collector against overhead line is detected or determined using sensor arrangement data, a memory with spatially resolved contact pressures for the power collector and a position ascertaining unit. At a motor vehicle position determined by the position ascertaining unit, an associated contact pressure is read out from the memory and automatically set by the control unit or signaled to a motor vehicle driver. A method for raising a power collector pantograph onto an overhead line is also provided.

An operational system of the present disclosure is an operational system for a plurality of fuel cell electric vehicles. The operational system is equipped with a decision unit that decides a single operational route based on supply amounts of hydrogen available from a plurality of hydrogen stations respectively, from among a plurality of candidates of an operational route of each of the fuel cell electric vehicles, and a scheduling unit that schedules the filling of each of the fuel cell electric vehicles with hydrogen at the hydrogen station or hydrogen stations included on the decided operational route. The decision unit decides the new operational route based on post-change available supply amounts of hydrogen in the case where the supply amounts of hydrogen available from the respective hydrogen stations change when each of the fuel cell electric vehicles runs on the decided operational route.

A method for controlling an electric hand truck includes determining whether user manipulation is present due to a user input on the electric hand truck; and, if there is no user manipulation, then braking an electric motor that drives the wheels of the electric moving vehicle in a softlock manner in which, instead of power being applied to the electric motor, electrodes of the electric motor are short-circuited.

An apparatus comprises a power electronic energy conversion system comprising a first energy storage device configured to store DC energy and a first voltage converter configured to convert a second voltage from a remote power supply into a first charging voltage configured to charge the first energy storage device. The apparatus also includes a first controller configured to control the first voltage converter to convert the second voltage into the first charging voltage and to provide the first charging voltage to the first energy storage device during a charging mode of operation and communicate with a second controller located remotely from the power electronic energy conversion system to cause a second charging voltage to be provided to the first energy storage device during the charging mode of operation to rapidly charge the first energy storage device.

The disclosure relates to an eco-friendly vehicle and a method of controlling the eco-friendly vehicle, and optimizing the temperature of the battery of the eco-friendly vehicle towing the vehicle to be towed. The method of controlling the eco-friendly vehicle includes measuring, by a controller, a temperature of a battery during towing driving while a vehicle to be towed is connected, applying, by the controller, the measured battery temperature to a predetermined function to obtain a trend of battery temperature change, predicting, by the controller, a point in time when the temperature of the battery exceeds a predetermined reference temperature based on the trend of battery temperature change, and starting, by the controller, cooling the battery before reaching the predicted excess point.

A method (100) for operating a vehicle (1) with an electric drive-train (2), wherein this electric drivetrain (2) is fed via a DC voltage source (3) and a converter (4) for converting the DC voltage into a single-phase or multiphase AC voltage, comprising the steps: —it is detected (110) that the vehicle (1) is stopped; — it is checked (120) on the basis of at least one specified criterion (10) whether the vehicle (1) is expected to be stopped only briefly; —in response to the fact that the vehicle (1) is expected to be stopped only briefly, the vehicle (1) is transferred (130) from the ready-to-drive state into a disabled state, wherein in this disabled state the vehicle (1) is protected against unauthorized use but the converter (4) continues to be supplied with the DC voltage from the DC voltage source (3); —in response to the fact that the vehicle (1) is not expected to be stopped only briefly, at least one functional test of the electric drivetrain (2), said test being provided for powering down the electric drivetrain (2), is performed (140), and after the termination of this functional test the vehicle (1) is transferred (150) into a switched-off state, in which the vehicle (1) is secured against unauthorized use and the supply of the converter (4) from the DC voltage source (3) is interrupted.

A cart may include a driving wheel, a motor configured to rotate the driving wheel, a motor drive circuit configured to drive the motor, a motor brake circuit configured to electrically brake the motor, a control device configured to control the motor via the motor drive circuit and the motor brake circuit so that a travelling speed of the cart becomes equal to or lower than an upper limit travelling speed, and a temperature sensor configured to detect a temperature of the motor brake circuit. The control device may be configured to change the upper limit travelling speed to a second upper limit travelling speed lower than the first upper limit travelling speed when the upper limit travelling speed is a first upper limit travelling speed and the temperature detected by the temperature sensor exceeds a first predetermined temperature.

A charging amount calculation apparatus calculates an amount of power consumption by a battery for running along a running route and a during-running charging amount received by a power reception apparatus from at least one second power feeding facility. The charging amount calculation apparatus calculates a pre-running charging amount based on the amount of power consumption and the during-running charging amount.
