What the onboard charger limit means for Chevy EV owners
The Chevy Bolt EV, Bolt EUV, and Equinox EV share an 11.5 kW onboard AC charger. At 240V, that translates to a maximum draw of roughly 48 amps. A 40-amp Level 2 charger on a 50-amp dedicated circuit delivers approximately 9.6 kW, which is the practical daily sweet spot for most Bolt and Equinox owners. The difference in daily charging speed between 40 and 48 amps is small enough that most owners never notice it.
Worth noting
A 40-amp circuit restores about 25 miles of range per hour for both models.
A 48-amp charger on a 60-amp circuit adds speed only up to the car's onboard limit — the gain is marginal for these models.
Matching circuit to the vehicle's real limit avoids unnecessary panel work.
Why most Bolt and Equinox owners do not need a 60-amp circuit
Many home charger retailers and installer packages default to 48-amp chargers and 60-amp circuits. For some vehicles that makes sense. For the Bolt EV and Equinox EV, the onboard charger will not use the extra headroom. The added circuit cost, breaker size, and panel demand are real — the extra speed is not.
Worth noting
A 48-amp charger on these vehicles charges at nearly the same rate as a 40-amp unit.
The only practical reason to go 60-amp now is to future-proof for a higher-limit vehicle.
A 50-amp dedicated circuit is the standard and common choice for these models.
Planning the installation for your garage
Whether the garage is attached or detached, the installation planning steps are the same. Confirm panel capacity, identify the conduit route, choose a mounted charger location that fits the cable reach to the charge port, and pull the permit.
Worth noting
Attached garage: straightforward conduit run from panel to charger wall mount.
Detached garage: review the existing feeder and subpanel capacity before sizing the circuit.
Finished garage walls: discuss conduit options with the installer before finalizing placement.
Chevy Bolt and Equinox EV charging FAQ
Common questions from Minnesota Bolt EV and Equinox EV owners planning a home installation.
Worth noting
Do I need a 48-amp or 40-amp charger? For most owners, 40 amps is the right call. The Bolt and Equinox EV onboard charger limits the speed difference to nearly zero.
Can I use the same charger if I buy a different EV later? Yes — a J1772 charger works with all non-Tesla EVs. Check the amperage of your next vehicle when upgrading.
Does Minnesota require a permit for this circuit? Yes. A dedicated 240V circuit for an EV charger requires a permit and inspection in most Minnesota jurisdictions.
