Power Source Adaptor For Charging Directly And Mobile Terminal

摘要

The application discloses a power source adaptor for charging directly and a mobile terminal, where the power source adaptor for charging directly is timed to communicate with a mobile terminal which is a charging object, in the UART communication mode to obtain a change in voltage of a battery in the mobile terminal, adjusts dynamically a volt value of charging voltage output by the power source adaptor for charging directly according to the varying voltage of the battery, and charges directly the battery in the mobile terminal using the charging voltage.

主权项

1. A power source adaptor for charging directly, comprising:
a charging interface configured to be externally connected with a mobile terminal, and comprising a power source pin, a ground pin, and two communication pins disconnected from each other; an AC to DC converting unit configured to convert an external AC input power source into charging voltage required for the mobile terminal, and to output the charging voltage via the charging interface; and a controlling unit, connected with the charging interface, configured to conduct UART communication with the mobile terminal through the communication pins, after the charging interface is connected with the mobile terminal, to adjust the charging voltage output by the AC to DC converting unit.
