How many kWh to charge a Chevy Blazer?
The energy needed to fully recharge a Chevy Blazer EV depends on which battery pack is installed. In practice, you’re looking at roughly 90 kWh of wall energy for the smaller 78 kWh usable pack, or about 110 kWh for the larger ~97 kWh usable pack, when charging from 0% to 100% and including typical losses.
Battery options and usable capacity
Chevrolet’s Blazer EV uses GM’s Ultium battery architecture and is offered with at least two battery configurations. The figures below reflect common baselines used by Chevrolet and the automotive press for planning purposes.
- 82 kWh gross battery pack (approximately 78 kWh usable capacity).
- 104 kWh gross battery pack (approximately 97 kWh usable capacity).
Note: The exact usable capacity can vary slightly by model year, trim, and battery health. For precise figures, check the specific vehicle’s display or owner’s manual.
Conclusion for this section: The Blazer EV’s full-charge energy requirement scales with pack size — roughly 78 kWh usable for the smaller option and about 97 kWh usable for the larger option. When you factor charging losses, the total energy drawn from the wall is higher than the battery’s usable capacity.
Estimated energy drawn from the wall to reach a full charge
To recharge from empty to full, you must account for charging losses and efficiency. The following estimates assume charging from near 0% to near 100%, with typical real-world efficiency ranges.
- Smaller pack: about 87–90 kWh drawn from the wall (roughly 78 kWh usable plus ~10–12 kWh losses).
- Larger pack: about 107–110 kWh drawn from the wall (roughly 97 kWh usable plus ~10–13 kWh losses).
These figures are approximate. Real-world losses depend on charger type, ambient temperature, battery temperature, and charging rate. Many drivers opt to charge to around 80–90% for daily use to preserve battery health, which reduces the wall energy required for a given trip.
Charging speeds and practical charging considerations
Charging performance depends on the power source and vehicle configuration. The Blazer EV supports both AC Level 2 charging and DC fast charging, with commonly cited capabilities as follows.
- AC Level 2 charging: onboard charging rates typically around 11 kW on standard setups, with an option to up to about 19 kW on certain trims or equipment packages.
- DC fast charging: peak charging power up to roughly 190 kW, enabling rapid top-ups from low to higher states of charge under suitable conditions.
Note that charging power often tapers as the battery fills, so the fastest rates occur early in a session while the final 10–20% takes longer than the middle portion.
Summary
The energy needed to charge a Chevy Blazer EV depends on the battery size installed. For planning, expect approximately 90 kWh of wall energy for the 78 kWh usable pack and about 110 kWh for the 97 kWh usable pack, with losses making the wall draw higher. Real-world charging speeds vary by source and conditions: Level 2 home charging generally around 11 kW (often up to 19 kW on some trims), while DC fast charging can approach ~190 kW when conditions permit. Always refer to your specific vehicle year, trim, and onboard displays for the most precise figures.
