The onboard charger input voltage measurement changed too much between switching cycles compared to acceptable range, causing reduced AC charge rate. This alert indicates an unexpected and sudden drop or spike in the measured voltage has occurred, and it is frequently associated with a condition affecting the supply voltage from the AC grid.
