  • Patent number: 11207999
    Abstract: A charger includes a first connection port, a second connection port, a DC-DC converter, a first microcontroller, and a second microcontroller. The DC-DC converter is configured to convert a first DC voltage into a second DC current/voltage according to a regulation signal, and output the second DC current/voltage through the second connection port. The second DC voltage is lower than the first DC voltage. The first microcontroller is configured to communicate with a DC charging station by handshake via the first connection port. When the handshake between the first microcontroller and the DC charging station succeeds, the first microcontroller generates a regulation indication according to a result of the handshake between the first microcontroller and a battery, the second microcontroller generates the regulation signal according to the regulation indication, and the first DC voltage is supplied by the DC charging station.

  • Patent number: 9089006
    Abstract: An intelligent heater includes a first induction coil, a control panel, a power supply unit, a storage unit, a data transmission interface, and a controlling unit. The control panel includes an input unit for inputting, adding, amending, deleting or refreshing a cooking data and a display unit for showing an operating condition of the intelligent heater. The power supply unit is connected with the first induction coil for providing a first power to the first induction coil. The storage unit is used for storing the cooking data. The data transmission interface is used for transmitting the cooking data. The controlling unit is used for controlling the power supply unit to provide an electricity quantity of the first power to the first induction coil according to the cooking data, so that a heat quantity and a heating time required for heating a first foodstuff container are adaptively adjusted.

  • Patent number: 8658950
    Abstract: A heating device includes a first induction coil, a second induction coil, a control panel, a power supply unit and a controlling unit. The control panel issues an adjusting signal. The power supply unit provides a first power and a second power to the first induction coil and the second induction coil, respectively. The controlling unit generates a control signal to the power supply unit according to the adjusting signal, thereby controlling the first power and the second power. Electrical energy is transmitted to the first induction coil and the second induction coil and the frequency difference between the first power and the second power is greater than 15 kHz or smaller than 1 kHz during a first time interval under control of the controlling unit. No electrical energy is transmitted to one of the first induction coil and the second induction coil during a second time interval under control of the controlling unit.
