Abstract

The invention provides a terminal, a charger and a charging method. The terminal and the charger are connected. The terminal comprises a first transmitting unit, a second transmitting unit and a charging unit. The first transmitting unit sends a voltage reduction request to the charger according to a voltage-reduction charging protocol when the charger charges the terminal through a first charging line in a universal serial bus. The second transmitting unit sends a voltage reduction control command to the charger to enable the charger to reduce the charging voltage to a target charging voltage required by the terminal when the terminal receives a voltage reduction request response from the charger. The charging unit receives the target charging voltage of the terminal through a second charging line in the universal serial bus to enable the charger to provide the target charging voltage for the terminal and charge the terminal at the target charging voltage. By adopting the technical scheme of the invention, the problem that a terminal produces a lot of heat in the charging process can be solved, and the user experience can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to a terminal, a charger and a charging method. Background technique [0002] Current mobile devices (such as mobile phones) and other terminals mainly rely on the high voltage on the VBUS line in the USB line to realize the fast charging function, such as figure 1 As shown, the 9V voltage on the serial bus VBUS line is stepped down by the voltage converter changer (for example, converted to 4.35V) and then supplied to the battery to realize fast charging. With the increasing power consumption of the current terminal, due to the restriction of the conversion efficiency of the charger module during fast charging, the mobile phone will heat up seriously, which undoubtedly increases safety hazards and also reduces user experience. [0003] Therefore, how to avoid severe heating of the terminal during fast charging has become a technical problem to be solved urgently. Cont...
