Title:
CONVERSION CIRCUIT FOR SERIES CHARGING AND PARALLEL POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2023/123729
Kind Code:
A1
Abstract:
Disclosed in the present application is a conversion circuit for series charging and parallel power supply, which conversion circuit realizes automatic switching between a series connection during charging and a parallel connection when a charger is unplugged. By means of a method for series charging and parallel power supply, the balance between two batteries during parallel discharging and series charging of the batteries can be maintained, and the problem of mutual large-current charging caused by a tiny voltage difference when the two batteries are directly connected in parallel can be solved, thereby prolonging the service life of the batteries.
