Abstract

The invention provides a charge-discharge system and a charge-discharge method for a mobile power supply. The charge-discharge system comprises a load detection unit, a charge unit, a discharge unit and a control unit, wherein the load detection unit is used for detecting whether the mobile power supply is connected with a load or not; the charge unit is used for outputting a charge current to charge the battery of the mobile power supply; the discharge unit is used for outputting a discharge current to discharge to the load; and the control unit is used for receiving an input current and adjusting the charge current output by the charge unit and the discharge current output by the discharge unit according to the magnitude of the input current and the discharge current. Therefore, a beneficial effect of synchronous charging and discharging, and the balancing of the charge-discharge currents is realized.

Description

【Technical field】 [0001] The invention relates to a charging and discharging system and method for a power supply, in particular to a charging and discharging system and method for a mobile power supply. 【Background technique】 [0002] With the continuous advancement of electronic technology, especially the increasing popularity of portable mobile electronic devices, such as mobile phones, tablet computers, digital cameras, etc., have become indispensable tools in daily life. These electronic products generally have built-in batteries. Due to their limited battery capacity, their battery life is limited to a certain extent. Especially when they go out or travel, they often cannot be charged in time with the charger of the AC grid, which brings great harm to people's work and life. A lot of inconvenience. The appearance of mobile power has solved this difficult problem. [0003] A mobile power supply is a portable charger that integrates power storage and charging functions...
