Chevrolet Blazer EV charger questions, answered
The math comes from the same NEC 220.82 calculation we run in the assessment.
Do I need a panel upgrade for a Chevrolet Blazer EV?
Not necessarily. The Chevrolet Blazer EV draws up to 48A on Level 2 charging, which requires a 60A breaker under NEC continuous-load rules. Whether your panel can add that depends on its size and existing loads, many 200A panels and even some 100A panels have room. A NEC 220.82 load calculation is the only way to know before you spend $2,000 to $5,000 on a service upgrade.
What size charger does the Chevrolet Blazer EV need?
The Chevrolet Blazer EV LT RWD accepts up to 11.5 kW (about 48A) on Level 2 AC charging. A matched 48A charger on a 60A breaker fully utilizes the car's onboard charger. A smaller 32A or 24A charger still works and may avoid a panel upgrade.
How long does it take to charge a Chevrolet Blazer EV on Level 2?
At its maximum 11.5 kW Level 2 rate, a Chevrolet Blazer EV takes about 7.4 hours to go from empty to full on its 85 kWh battery. Most owners charge overnight from 20% to 80%, which takes roughly 4.4 hours.
What breaker size is required for a Chevrolet Blazer EV EV charger?
For the maximum 48A charging speed the Chevrolet Blazer EV supports, NEC 625.41 requires a 60A breaker (continuous load = charger amps × 1.25). A smaller breaker is acceptable if you set the charger to a lower amperage.
What connector does the Chevrolet Blazer EV use?
The Chevrolet Blazer EV LT RWD uses a NACS connector for AC and DC fast charging. Most Level 2 home chargers ship with the matching plug or include an adapter.
Can a 100-amp panel handle a Chevrolet Blazer EV charger?
Sometimes, especially with gas heat. A 100A panel has a safe continuous capacity of 80A. The Chevrolet Blazer EV draws 48A at max Level 2 speed. Whether that fits depends on your existing loads (HVAC, range, dryer, water heater). Many 100A homes with gas heat can add a 24A or 32A charger without a service upgrade.
