A universal charging system is disclosed. In one example embodiment, the universal charging system includes a charging adapter configured to be mounted on a light electric vehicle (LEV), a charging station, and a processor configured to control charging of the LEV. The charging adapter may have electrical contacts for docking with a charging station and a charging interface for supplying power from the charging station to a battery of the LEV. The charging station may have at least one docking unit for receiving the charging adapter of the LEV. The at least one docking unit may have further electrical contacts for connecting to the charging adapter of the LEV.

Techniques are disclosed for systems and methods to provide reduction in connectivity interruptions between vehicle docking stations and a management server for facilitating micro-mobility vehicle sharing services. To maintain communication sessions between the vehicle docking stations and the management server, heartbeat signals are transmitted periodically by each of the vehicle docking stations to the management server. An unavailability of the connection between a vehicle docking station and the management server may be detected based on an interruption to the heartbeat signals. In response to determining the unavailability of the connection, the management server may instruct a vehicle within a predetermined distance of the vehicle docking station to establish a short-range connection with the vehicle docking station and retrieve docking station data from the vehicle docking station.

Modular battery packs are disclosed and can be used in different devices and systems, such as electric vehicles, electric aircrafts, and electric scooters. Each modular battery pack includes a trace unit to record information about the battery pack, which is transmitted to a distributed data management system. The distributed data management system maintains a unique record entry for each modular battery back, based on which the residual fair market value can be assessed. This evaluation system facilitates the reselling, renting, and/or exchanging of modular battery packs at an online platform and/or at a physical battery sale, rental, and/or swapping station. Modular battery packs may also be recycled from one application to another application. For example, when a modular battery pack from an electric vehicle is degraded to certain level, it may be recycled and used in an energy storage system or other systems having lower requirements for battery performances.

To reliably connect a device to be charged such as a robot and a charging device. According to the present disclosure, there is provided a charging device including a charging stand having a charging terminal to be connected to a device to be charged and an engaging portion that performs positioning with the device to be charged; and a support member that supports the charging stand movably in the horizontal direction. With this configuration, the charging stand can be moved in the horizontal direction. Therefore, it is possible to reliably connect the device to be charged such as a robot and the charging 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.

A child drift car comprises a car frame, a wheel assembly, a seat, a driving mechanism and a direction control mechanism; the wheel assembly comprises a driving wheel assembly, and the driving wheel assembly comprises driving wheels, and an axle fixedly connected to the driving wheels; the driving mechanism comprises a driver and a transmission device; the direction control mechanism comprises a steering column, a steering wheel fixedly connected to the steering column, and a steering device separately connected to the steering column and the driving wheel assembly; the driving mechanism further comprises a main shaft rotatably disposed on the car frame along its own axis and driven by the transmission device to rotate, and the main shaft is connected to the axle through a universal joint. When the driving wheels turn, the speed of the driving wheels is not affected, and a higher drifting speed can be achieved.

A device for transporting a payload (to include a human user) over varied terrain. A platform accommodates the payload. A pair of wheel clusters are mounted to opposite ends of the platform and are powered in rotation relative thereto. Each includes at least two co-planar wheels powered by electric motors. A latch is hand-operable (without tools) to secure the cluster to the platform and, alternatively, allow the cluster to be detached from the platform and rotated 90 to lie parallel thereto. An electrical connector conducts electric power from the platform to the cluster when the latch is operated/actuated to secure the cluster to the platform, and is configured such that it does not impede or obstruct detaching the wheel cluster from the platform, with no requirement that the user take any additional step (other than actuating the latch) to detach the wheel cluster.

Provided are a control method, a vehicle frame, a power driving assembly and a vehicle. The vehicle frame is configured to be connected with the power driving assembly, and the vehicle frame is provided with a manipulation assembly and a controller for controlling the power driving assembly. The control method includes that: after the vehicle frame is connected to the power driving assembly and a communication connection is established between the controller and the power driving assembly, the controller detects a manipulation instruction from the manipulation assembly; and in response to detecting the manipulation instruction from the manipulation assembly and determining that the manipulation instruction corresponds to the power driving assembly, the controller generates, according to the manipulation instruction, a control instruction for controlling the power driving assembly, and sends the control instruction to the power driving assembly.

A universal charging system is provided. In one example embodiment, the universal charging system includes a charging adapter configured to be mounted on a light electric vehicle (LEV), a charging station, and a processor configured to control charging of the LEV.
