Method for controlling electric hand truck and apparatus therefor
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.
REDUCING SWITCHING-ON AND SWITCHING-OFF PROCESSES IN AN ELECTRIC DRIVETRAIN
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.
Auxiliary power output for battery management system
A utility cart includes a stored energy device that can be in the form of a Lithium Ion battery pack. The battery pack can include a main power output useful to drive high voltage components as well as the electric motor for motive power. The battery pack can also include one or more auxiliary outputs useful to provide auxiliary power to various other components. The auxiliary outputs can be either low and/or high voltage outputs. An auxiliary DC/DC output can be used to step down high voltage of the Lithium ion battery pack to lower voltages. A motor controller supply can also be provided as an auxiliary output to provide some power to a motor controller.
POWER TRANSFER SYSTEM, POWER TRANSMISSION SYSTEM, POWER TRANSFER METHOD
A power transfer system includes: a compact mobility; a ground unit disposed on a second lane which is a driving lane for the compact mobility, the ground unit being capable of wireless power transfer; and a controller that controls the ground unit. The compact mobility has an amount of electric power that can be stored less than a predetermined amount, and travels at a speed dependent on electric power wirelessly received from the ground unit. When a pedestrian is sensed in the second lane, the controller forces the compact mobility to decelerate by reducing transmission power from the ground unit to the compact mobility, as compared to when the pedestrian is not sensed in the second lane.
Bicycle control system
A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.
Vehicle control device, control method, non-transitory storage medium, and vehicle
A vehicle control device for a vehicle includes a processor. The vehicle includes a first battery, a second battery, an auxiliary load powered by the second battery, and a DC-to-DC converter configured to supply electric power from the first battery to either the second battery or the auxiliary load, or to both of the second battery or the auxiliary load. The processor is configured to: determine the state of a start switch and the boarding state of the vehicle; acquire the voltage of the second battery; and when the processor determines that the vehicle is in a non-started on-board state, determine based on the voltage of the second battery an order in which the DC-to-DC converter and the auxiliary load are driven. The non-started on-board state is a state in which the start switch is off and a user is presumed to be in the vehicle.
Systems and methods for switching modes of providing content on a charging station display
A charging station for an electric vehicle determines that a first person is in proximity to the charging station and identifies whether the first person is a user of the charging station. In accordance with a determination that the first person is a user of the charging station, the charging station provides, using a first mode for selecting content for users of the charging station, first content for display. The charging station determines that a second person is in proximity to the charging station and identifies whether the second person is a user of the charging station. In accordance with the determination that the second person is not a user of the charging station, the charging station provides, using a second mode for selecting content distinct from the first mode for selecting content, second content for display. The second mode provides content for non-users of the charging station.
Hand-pushed motorized movement device
A motorized movement device includes a frame, first and second wheels connected to the frame, and first and second motors connected respectively to the first and second wheels that are commandable by respective command signals. The motorized device also includes an inertial measuring unit configured to detect the longitudinal acceleration, pitch angular speed, and yaw angular speed of the movement device and for providing signals representative of the same. The motorized device also includes sensors for detecting speeds of the wheels and configured to provide signals representative thereof. The motorized device further includes a control unit comprising a module for estimating the slope, and longitudinal thrust exerted by a user to the device, yaw torque applied by the user. The control unit also includes a module for compensating the slope, a thrust amplifying module, a yaw torque amplifying module, and a torque allocating module.
MULTIFUNCTION LIGHT VEHICLE CHARGING PLATFORM
A multifunction electric vehicle charging platform is provided. The platform includes a housing and at least one display unit placed in the housing. The platform further includes a content management unit configured to control receiving content and display the content on the at least one display unit. The platform includes a charging unit configured to be connected to at least one light electric vehicle (LEV) and to provide power to the at least one LEV. The platform includes at least one sensor attached to the housing and configured to collect data associated with the at least one LEV. The platform further includes a communication unit configured to communicate with a backend system.
SYSTEMS AND METHODS FOR DETERMINING A POSITION OF AN INDIVIDUAL RELATIVE TO AN ELECTRIC VEHICLE CHARGING STATION USING CAMERAS
A device detects, using at least one camera, a human subject at a position within a first field of view relative to a first side of at least two sides of a device, the first side displaying first content on a first display of the first side. In response to detecting the human subject at the position within the first field of view, the device generates a first type of impression count for the human subject and tracks, using the camera, motion of the human subject. In accordance with a determination that the human subject moves from the position within the first field of view to a position within a second field of view relative to a second side of the at least two sides, the device updates the first type of impression count to a second type of impression count and stores the respective type of impression count.
