Portable power source charging method, power source adapter and portable power source

Abstract

The invention discloses a portable power source charging method, a power source adapter and a portable power source. The portable power source charging method is applied to the power source adapter, and comprises the steps of: communicating with the connected portable power source by a charging handshake protocol, and establishing a communication connection with the portable power source; receiving a target charging parameter sent by the portable power source and required for charging, wherein the target charging parameter is related to the series-parallel mode of a battery pack inside the portable power source; and adjusting a charging parameter for the portable power source according to the target charging parameter. By adopting the method, the charging parameter of electric energy output by the power source adapter can be matched with the charging demand of the portable power source, the voltage conversion process of the portable power source on the charged electric energy is reduced, and the purposes of reducing the charging loss of the portable power source and reducing the heat dissipation burden of the portable power source are fulfilled.

Description

[0003] In order to enable the mobile power supply to supply power, the mobile power supply also needs to be charged in the case of power shortage; the current charging method of the mobile power supply is mainly to connect the mobile power supply to the power adapter, and the power adapter outputs a fixed voltage of electric energy to charge the mobile power supply; however , the charging voltage required by the battery pack of the mobile power supply often does not match the fixed voltage output by the power adapter. At this time, it is necessary to convert the fixed voltage electric energy output by the power adapter. The charging voltage required by the power supply is 8.4V. At this time, the voltage conversion process of 20V to 8.4V is required, which leads to a large charging loss of the mobile power supply and will also greatly affect the heat dissipation of the mobile power supply.
