Abstract:
The present disclosure discloses a charging device, a charging method, a power adapter and a terminal. The charging device includes a charging receiving terminal, a voltage adjusting circuit and a central control module. The charging receiving terminal is configured to receive an alternating current. The voltage adjusting circuit includes a first rectifier, a switch unit, a transformer and a second rectifier. The first rectifier is configured to rectify the alternating current and output a first voltage. The switch unit is configured to modulate the first voltage to output a modulated first voltage. The transformer is configured to output a second voltage according to the modulated first voltage. The second rectifier is configured to rectify the second voltage to output a third voltage. The voltage adjusting circuit applies the third voltage to a battery directly.

Claim (Index 11):
A charging method, by using the charging device according to  claim 1  and comprising:\n receiving an alternating current from a mains supply; \n rectifying the alternating current to output a voltage with a first pulsating waveform, and modulating the voltage with the first pulsating waveform to obtain a modulated voltage with the first pulsating waveform; \n converting the modulated voltage with the first pulsating waveform to a voltage with a second pulsating waveform, and rectifying the voltage with the second pulsating waveform to output a voltage with a third pulsating waveform; and \n directly applying the voltage with the third pulsating waveform to a battery of a terminal so as to charge the battery; \n sampling and holding a peak voltage of the voltage after a secondary rectifying, sampling a zero crossing point of the voltage after the secondary rectifying, and performing a leakage on a peak voltage sampling and holding unit for sampling and holding the peak voltage at the zero crossing point; \n sampling a peak voltage in the peak voltage sampling and holding unit so as to obtain a voltage sampling value; \n obtaining status information of the battery based on bidirectional communication with the terminal, adjusting voltage and/or current applied to the battery based on the status information of the battery and the voltage sampling value, in response to a charging requirement of the battery, wherein, a magnitude of the voltage and/or the current output applied to the battery is periodically changed, and the voltage and/or the current applied to the battery in response to the charging requirement of the battery, means that the voltage and the current with the third pulsating waveform satisfy a charging voltage and a charging current when the battery is charged.
