- Lithium-ion batteries are charged using the constant-current, constant-voltage (CCCV) method, which manages voltage and current.
In CCCV charging, when the cell voltage is low, the current is constant. When the cell voltage reaches 4.2V,
the charge becomes a constant voltage charge, and the amount of current is reduced so that it does not exceed 4.2V.
- Lithium batteries require highly accurate control of charging voltage and charging current.
The PSA-series has an extremely small input resistance of approximately 40 mΩ (±5 A type and ±2 A type), enabling highly accurate measurements.
- Since measurement is made with a very small shunt resistance, voltage drop is small.
It can be used for current measurement of low-voltage devices and evaluation of battery and battery charge/discharge characteristics.
Examples of mobile devices: smartphones, wireless earphones, wearable devices, hair irons, laptop computers, etc.
- CAN 1ms update and 16bit analog 1ms update can be output simultaneously (option)
- Setting and logging are possible through the ammeter's USB Type-C connector using Coco Research's measurement management software LINKSHIP (free download).
