Abstract: A smart charging system for mobile vehicles includes a charging apparatus, a meter, and a cloud server. The charging apparatus is connected between an electric grid and an electric vehicle. The charging apparatus is supplied by the electric grid and then provides power to supply the electric vehicle. The meter is operatively connected between the electric grid and the charging apparatus. The meter has a communication with the electric grid to obtain supplied power from the electric grid to the charging apparatus. The cloud server is operatively connected to the electric grid and further operatively connected to the charging apparatus via a gateway apparatus to receive power-supplying information of the electric grid and power-charging information of the electric vehicle. Further, the charging apparatus smartly charges the electric vehicle according to the power-supplying information and the power-charging information.

Abstract: The present invention provides a cable protection device and a cable having the same. The cable protection device is configured for connecting two cables and includes a first protective casing and a second protective casing assembled with the first protective casing. The first protective casing has a hollow body for allowing one of the two cables to be disposed through. The second protective casing has a hollow body for allowing the other of the two cables to be disposed through. The interiors of the hollow body of the first protective casing and the hollow body of the second protective casing form a protective space respectively for covering a connecting portion of the two cables. Thus, the present invention also generates waterproof and dustproof effects.

Abstract: The present invention provides a cable protection device, a cable having the same, and an assembling method thereof. The cable protection device is configured for connecting two cables (2, 2?) and includes a first protective casing (1) and a second protective casing (1?) assembled with the first protective casing (1). The first protective casing (1) has a hollow body (10) for allowing one cable (2) to be disposed through. The second protective casing (1?) has a hollow body (10?) for allowing the other cable (2?) to be disposed through. The interiors of the hollow body (10) of the first protective casing (1) and the hollow body (10?) of the second protective casing (1) form a protective space (11, 11?) respectively for covering a connecting portion of the two cables (2, 2?). Thus, the present invention also generates waterproof and dustproof effects.

Abstract: Disclosed is a power supply unit provided with AC/DC voltage detection and a power supply system incorporating such power supply unit. The power control unit of the power supply unit can manipulate the first stage power circuit and the bypass switch thereof according to the form and magnitude of the first voltage which is inputted to the power supply unit in order to boost the overall operating efficiency. When the inventive power supply unit is applied to a high-level DC power supply system, the problem that the power supply unit can not output a rated output voltage due to an insufficient DC first voltage can be avoided.
