How do you know if a battery is charging?

The battery is charging when the current is flowing across the diode and produces a voltage drop. To detect if a battery is charging, the battery voltage must be less than or equal to the charging input. I've come up with this naive circuit that powers a comparator with the battery voltage since it's typically higher than the charger's.

How do you charge a battery?

There are two main ways to charge a battery. One is Constant Current (CC) charging. The other is Constant Voltage (CV) charging. In CC charging, the charger sends a steady current to the battery. As the battery becomes full, its voltage increases. When it reaches a certain point, the charger switches to CV charging.

How do I measure charge current?

Use an ACS711 (or similar) to measure the charge current. Or, if you want, you can use a shunt and a current shunt amplifier (such as INA199) to measure the charge current on the low-side.

How do battery charging indicators work?

Commonly most battery charging indicators utilize the voltage level of the battery to indicate its charging condition, here instead of voltage the current (amps) magnitude is used for measuring the charging status. Using current as the measuring parameter enables a more accurate assessment of the battery charging status.

When should I measure battery voltage?

Generally you want to get your measurements as close to the open circuit voltage as possible if you are doing voltage based state of charge indication. So ideally you want to measure the voltage if no current is going in or out of the battery and have waited for some minutes to let the battery settle (relaxation effect), waiting is usually omitted.

How do I stop a battery from charging?

It's common to stop charging momentarily to measure the battery voltage and correct the position of the charge process in the V/SOC graph. Attach a voltage divider to the output. Use an ADC to measure the output voltage of the divider. No problem. Use a capacitor at the ADC input to make sure any ripple voltage from the charger is removed.
