Title:
MOBILE POWER SUPPLY AND DISCHARGING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2020/097801
Kind Code:
A1
Abstract:
Disclosed are a mobile power supply and a discharging method therefor. The mobile power supply comprises a battery cell, a boost-buck module, a first interface, and a charging and discharging management unit. The charging and discharging management unit is electrically connected to the boost-buck module and the first interface, and used for managing the boost-buck module. As charging current jumps to a certain range during actual charging, the charging current can instantly achieve or exceed a preset current value even if the charging current is small when the mobile power supply charges small mobile electronic equipment. When the charging and discharging management unit detects that the charging current achieves or exceeds the preset current value, the boost-buck module can be controlled to continuously perform discharging on the first interface within the following time Δt, and with the charging of small current, the operation continues to carry out, the time Δt can be continuously refreshed, so that the mobile power supply can perform continuous small-current charging on the small mobile electronic equipment.
