TC/CC/CV charging method

What is the TC / CC / CV charging method?

It is a three-stage process of charging Li-ion cells that ensures that the cell is in good condition by charging with the right current at each stage and ending the charging process at the right time.
The individual stages of the TC / CC / CV process are:

• TC phase: cells discharged below 2.9V are "woken up" by a lower current.
• CC phase: after reaching 2.9V, the cell is charged with 0.5A DC.
• CV phase: when the cell is almost charged, the charger switches to charging with decreasing current until it reaches 4.2V on the cell. After reaching 4.2V, the charging process is completed - the battery is fully charged.
