Title:
SYSTEM FOR CHARGING AND DISCHARGING LITHIUM ION BATTERY, CONTROL APPARATUS AND RELATED METHOD
Document Type and Number:
WIPO Patent Application WO/2019/015007
Kind Code:
A1
Abstract:
Disclosed are a system for charging and discharging a lithium ion battery, a control apparatus and a related method, relating to the technical field of lithium ion battery charging and discharging. According to the technical solution disclosed in the present invention, a charging and discharging current of a lithium ion battery is enabled to be an oscillating current by means of an oscillation circuit formed by a variable-frequency triggered oscillation charging and discharging apparatus and the impedance characteristic of the lithium ion battery itself, so that the lithium ion battery or a battery pack avoids direct-current charging and discharging, thus eliminating polarization and lithium precipitation of the lithium ion battery, prolonging the service life of the lithium ion battery, increasing a lithium ion charging threshold voltage, increasing the charge amount of the lithium ion battery, controlling the temperature rise inside the battery and widening a temperature application range of the lithium ion battery.
