Abstract

A power adapter with CV/CC dual mode suits charging applications. The power adapter holds voltage steady in CV and limits current in CC. Accuracy and turnover of the power adapter ensure safe, efficient charging.

1. Constant Voltage Mode

Early charging uses CV mode, where the power adapter keeps output voltage constant within ±1%. Stable CV output lets the power adapter supply the right voltage without over-stressing the battery. Buyers check CV voltage accuracy of the power adapter so its charging voltage meets battery requirements.

2. Constant Current Mode

High-current charging uses CC mode, where the power adapter limits current to a set value to prevent over-current. Precise CC control keeps the power adapter charging steadily as battery internal resistance changes. Buyers confirm current accuracy and range of the power adapter to match different battery capacities.

3. Mode Turnover and Charging Curve

The power adapter turns over smoothly between CV and CC, giving a complete charging curve. Good turnover lets the power adapter switch automatically as battery voltage rises for the CV-CC transition. Buyers verify the charging curve of the power adapter so its turnover voltage and current cooperate to avoid overcharge or undercharge.

4. Charging Safety and Protection

The power adapter integrates OVP, OCP and SCP for safe charging. Robust protection lets the power adapter cut output on battery anomaly to prevent heating and damage. Buyers confirm protection and charge-termination logic of the power adapter so it works safely in every charging scenario.

Conclusion

Charging and LED applications need CV/CC dual mode of the power adapter; verify constant-voltage accuracy, current setting and turnover of the power adapter. Looking for power adapter samples or charging curves? Contact Simsukian for specs.
