Title:
LITHIUM BATTERY CHARGE AND DISCHARGE CONTROL METHOD AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/199539
Kind Code:
A1
Abstract:
The present application is applicable to the field of power supply technology, and discloses a lithium battery charge and discharge control method and a supply system, wherein, the above lithium battery charge and discharge control method includes: obtaining the current voltage of the lithium battery; when the current voltage is less than a preset first charging voltage threshold, charging the lithium battery through the preset first constant current; when the current voltage is greater than or equal to a preset second charging voltage threshold, charging the lithium battery through the preset second constant current; when the current voltage is greater than or equal to a preset third charging voltage threshold, stopping the charging of the lithium battery. The lithium battery charge and discharge control method and the power supply system provided by the present application perform staged charging control of the lithium battery by controlling the size of the charging current, avoiding directly using larger current to charge the over-discharged lithium battery, realizing the charging protection of the lithium battery.
