If you are looking for a specific component value (e.g., a burnt resistor near the MOSFET), it is common to find 0.22Ω to 0.47Ω current sense resistors
A small microcontroller (MCU) reads real-time current and voltage through shunt resistors. This data is fed to the LED/LCD graphic panel to display the charging status for each individual port.
