Abstract:
A network of collection, charging and distribution machines collects, charges and distributes portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). Vehicle diagnostic data of a vehicle using the portable electrical energy storage device is stored on a diagnostic data storage system of the portable electrical energy storage device during use of a respective portable electrical energy storage device by a respective vehicle. Once the user places the portable electrical energy storage device in the collection, charging and distribution machine, or comes within wireless communications range of a collection, charging and distribution machine, a connection is established between the collection, charging and distribution machine and the portable electrical energy storage device. The collection, charging and distribution machine then reads vehicle diagnostic data stored on the diagnostic data storage system of the portable electrical energy storage device and provides information regarding the diagnostic data.
Abstract:
Drive assemblies for electric devices, such as vehicles, include an electric motor that includes a rotor assembly and a stator assembly positioned within the rotor assembly. The stator assembly is fixed to a stationary axle and includes a pole and a coil around the pole. The rotor assembly is supported on the fixed stationary axle by bearings. The rotor assembly includes a housing to which a plurality of magnets are attached. A drive mechanism, such as a sprocket, pulley or gear is provided on the housing of the rotor assembly and rotates with the housing.

Abstract:
An image capturing method has: providing an image capturing area on a display screen of a user device; providing an indication area in the image capturing area; marking a license plate after identifying the license plate based on at least one license plate feature in the image capturing area; determining whether the marked license plate is located in the indication area and presented in a predetermined ratio; and capturing an image including the license plate in the image capturing area after the marked license plate is located in the indication area and presented in a predetermined ratio.
Abstract:
A computer-implemented method for recommending vehicle location is provided. Said method takes considerations of drifting effect during positioning of vehicle under a static state and analysis using various geographic data and historical positioning locations of the vehicle to recommend possible location of the vehicle to user, thereby assist user in finding the vehicle quickly on-site. Further provided is a system for recommending vehicle location.
Abstract:
A battery charging station includes a power bus, a power supplying unit, a first voltage converting unit and a processor. The power supplying unit receives a first power to generate a second power accordingly and transmits the second power to the power bus as a supplying power of the power bus. The first voltage converting unit is coupled to the power bus and is connected to a first battery removably disposed in the battery station. The processor sets the first voltage converting unit to operate in a first mode or a second mode, the first voltage converting unit in the first mode receives the supplying power from the power bus so as to charge the first battery. The first voltage converting unit in the second mode receives the electrical power from the first battery and generates a second mode power towards the power bus.

Abstract:
A liquid-cooled heat dissipation device is disclosed, comprising a main body, a centrifugal pump, an inlet pipe, an outlet pipe, a centrifugal fan and a motor. The main body comprises a shaft hole, liquid flow channels and airflow channels. The centrifugal pump guides a cooling liquid through the inlet pipe, main body and outlet pipe. The centrifugal fan guides air into the main body axially from the shaft hole. After passing through the centrifugal fan, the air forms centrifugal airflows and leaves the body radially through the airflow channels. With an extended flow path of the cooling liquid and the radial flow of the centrifugal airflow provided by the present invention, the temperature of the cooling liquid may be quickly reduced and the cooling effect may be improved. Thus, the structure is compact, small, light-weight, easy-to-assemble.
