Abstract

The invention relates to the technical field of charging, in particular to a power supply device, a power supply method and a power supply system. The device comprises a processor, a protocol physical layer and a power conversion module. The processor is used for collecting attribute information of the battery; the protocol physical layer is connected to the processor and the adapter, and is used for transmitting the attribute information to the adapter according to a preset protocol, generating a closing control signal, collecting an electronic voltage and sending the electronic voltage to the adapter, so that the adapter can adjust an output signal according to the attribute information, the electronic voltage of the battery and the conversion efficiency of the power conversion module; the power conversion module is connected to the adapter, the battery and the protocol physical layer and used for responding to the closing control signal, converting the output signal into an input signal matched with the battery and transmitting the input signal to the battery. According to the technical scheme, the defects that in the prior art, a power supply device is high in cost, and heating is large during high-power charging are overcome.

Description

technical field [0001] The present application relates to the technical field of charging, and in particular, relates to a power supply device, a power supply method, and a power supply system. Background technique [0002] With the widespread use of portable electronic devices such as notebook computers and mobile phones, the portable electronic devices use batteries as power systems, and the technology of how to charge the batteries conveniently and quickly becomes more important. [0003] The power supply device in the prior art requires an independent MCU (Microcontroller Unit, micro control unit) processor, which is costly and generates a lot of heat during high-power charging. Contents of the invention [0004] The purpose of this application is to provide a power supply device and a power supply method, and then at least to a certain extent overcome the power supply device in the prior art that requires an independent MCU processor, which is costly and generates hea...
