Description

technical field [0001] The present invention relates to the technical field of power management, in particular to a power management system for electronic equipment. Background technique [0002] In the prior art, in order to ensure that the electronic equipment can continue to work in the state of power failure, a group of batteries is generally added to the electronic equipment as a backup power supply, and both the batteries and the commercial power are electrically connected to the electronic equipment. In the case of charging, the commercial power converts 220V into a low voltage to charge the battery through the switching power supply, and a control relay will be set between the switching power supply and the battery to control charging and discharging. In the prior art, the control relay is usually controlled by a single-chip microcomputer. The single-chip microcomputer is electrically connected to the control terminal of the control relay through a driving circuit or...
