Abstract: A charging device for a mobile terminal and a mobile terminal are disclosed. The charging device includes a motor for power generation, a drive module, a charge pump module, a filtering and voltage regulation module and a control unit. The drive module is connected with an input end of the motor and is configured to obtain swing kinetic energy of the mobile terminal. The charge pump module is connected with an output end of the motor and is configured to boost a voltage output by the motor. The filtering and voltage regulation module is configured to perform direct current filtering and voltage regulation processing on a voltage output by the charge pump module, so as to output a charging voltage matching with a battery. The control unit is configured to accumulate charging current so as to adapt to the battery, and to control a charging process.

Abstract: Temperature characteristics of battery cells are detected. In accordance with one or more embodiments, an intercept frequency is detected for each battery cell, at which frequency an imaginary part of a plot of impedance values of the battery cell exhibits a zero crossing. The impedance values correspond to current injected into the cell. A temperature of the cell is determined based upon the detected intercept frequency for the cell and stored data that models operation of the cell. Various approaches are implemented with different types of circuits coupled to detect the impedance values of the respective cells.

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.
