The smart controller cannot store energy

Remove the control box cover and check the voltage from the red and black wires on top of relays. Intelligent controllers utilize sophisticated mechanisms to store energy, ensuring optimal efficiency and reliability. Unlike capacitors or batteries, these devices focus on real-time energy management rather than storage – think of them as traffic. The app says this when the car starts refusing charge because it has hit its charge limit (90% in your case) but the charger still hasn't provided as much charge as you requested via the app when you plugged it in.
