Title:
CONTROL SYSTEM AND CONTROL METHOD FOR BATTERY FORMATION AND CAPACITY GRADING, AND BATTERY POWER MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/186653
Kind Code:
A1
Abstract:
Disclosed are a control system for battery formation and capacity grading, a control method for battery formation and capacity grading, and a battery power management system. The control system comprises: a rectifier module, a DC bus, a plurality of DC conversion modules, a detection module, and a control module. The rectifier module converts alternating current into direct current according to a first control signal. The DC bus is used for accessing and transmitting direct current. The DC conversion module is used for performing voltage transformation. The detection module is connected with each battery, and is used for detecting the battery state of charge; if the battery state of charge has reached the full charge state, the detection module generates a first detection signal; if the battery state of charge has not reached the full charge state, the detection module generates a second detection signal. The control module is used for enabling the DC conversion module to output the boosted electric energy to the DC bus according to the first detection signal and to output the direct current after voltage reduction to the battery according to the second detection signal.
