Charging is much slower than expected; vehicle shows reduced kW even though charger is rated higher.

Safety first: No special hazard; this is typically a configuration or thermal issue.

• Step 1 – Check charger settings: In the Chevrolet app or charger interface, verify the maximum current setting and increase it within the limits of your circuit.
• Step 2 – Verify vehicle settings: Some EVs allow limiting charge current. Ensure the vehicle is set to allow full current.
• Step 3 – Monitor temperature: If the charger or cable becomes hot, the unit may be derating to protect itself. Improve ventilation and retest.
• Step 4 – Check utility programs: If enrolled in a time-of-use or demand response program, charging current may be reduced during peak times.
• Step 5 – Compare with another charger: If the vehicle charges at full speed on another Level 2 charger, the Chevrolet unit may need firmware updates or service.
