Customer ServiceHowever, as we all know lithium batteries are need to be charged, discharged, or even stored in a particular manner to extend their life. In this project, we will explore a circuit that will discharge the battery fully and provide the result of how much capacity the battery has.
To charge a battery using an SMU instrument, set the voltage source to the battery's voltage rating and the current limit of the source to the desired charging current. At the start of the charging cycle, since the battery voltage is less than the SMU instrument’s voltage output, current will flow into the battery.
This Lithium-Ion battery charger features a Command-Line Interface (CLI) that can be accessed via the Arduino’s RS232 serial port. The easiest way to connect to the CLI is to open the serial monitor of the Arduino IDE while connected to the charger using a FTDI USB to Serial converter. Please ensure that the Baud rate is set to 115200.
Li-Ion batteries must be charged using the Constant Current Constant Voltage (CC-CV) charging method. This method consists of charging the battery at a constant current until a certain voltage threshold is reached, then gradually reducing the charging such that the constant cell voltage is not exceeded.
Please proceed with calibrating the reading of the current by following the steps below: Connect a discharged Lithium-Ion battery to in series with a digital ampere meter (set to the 10 A range) to the terminals B+ and B-. Enter the . (dot) command and check the displayed value for which must match the measured current as closely as possible.
The Lithium-Ion battery is connected across the B+ and B- terminals. The battery charging current is regulated by switching P-Channel MOSFET (field-effect transistor) Q1 via pulse-width modulation (PWM). The PWM-enabled digital output pin 9 on the Arduino generates a PWM signal which drives the gate of the MOSFET Q1 through the NPN transistor Q2.
