Charger stops charging mid-session with no error
Why it happens here
This is usually a loose termination inside the charger or at the breaker, and heat cycling makes it worse over time. Florida's temperature swings in a garage work on connections that were not torqued to spec. It can also be a software glitch in the charger's firmware.
Our approach
We open the unit, check torque on every lug with a torque screwdriver, and test the circuit under load. If the terminations are fine, we check for a firmware update and test the connector. Most of these are fixed in one visit.
