Chevrolet EV Charging Speed Comparison
Here’s a clear look at how fast each Chevy EV charges, from the affordable Bolt to the massive Silverado, so you know exactly what to expect at the charger.
Charging speed is one of the most important factors when choosing an EV. It’s the difference between a quick coffee break and an hour-long wait. So, how do Chevrolet’s electric models stack up? Let’s break it down.
TL;DR
Chevrolet’s EV lineup spans a wide range of charging capabilities. The Silverado EV is a charging champion, leading the pack with peak speeds up to 350 kW . The Blazer EV, Equinox EV, and new 2027 Bolt EV sit in the mid-tier at 150–190 kW, offering solid road-trip capability . The older Bolt models charge much slower at 50 kW—which can make road trips a chore . The good news? The 2027 Bolt EV is a huge leap forward, charging more than 2.5x faster than its predecessor .
Key Takeaways
- Silverado EV is the fastest-charging Chevy: It can reach up to 350 kW peak and averaged 198 kW in independent testing, adding 100 miles in about 17 minutes .
- Equinox EV, Blazer EV, and new Bolt offer mid-tier speeds: These models all support up to 150 kW (or 190 kW for Blazer RWD), meaning you can go from 10% to 80% in roughly 30–40 minutes .
- Older Bolt models are slow: The previous-generation Bolt and Bolt EUV peak at just 50–57 kW, making them better suited for city driving than long road trips .
- Charger choice matters: An Equinox EV won’t always hit 150 kW if the charger can’t supply enough amperage. In one test, a 250 kW Tesla Supercharger actually charged an Equinox faster than a 350 kW unit .
- The new 2027 Bolt is a game-changer: It’s the first Chevy EV with a native NACS port and charges from 10% to 80% in about 25 minutes .
Chevrolet EV Charging Comparison Table

| 2025 Blazer EV RWD | 150-190 kW | ~30-40 min | ~85-102 kWh | All-around SUV charging |
| 2025 Equinox EV | 150 kW | ~40 min | ~85 kWh | Practical everyday use |
| 2027 Bolt EV | 150 kW | ~25 min | ~65 kWh | The new affordable road-tripper |
| Previous Bolt EV/EUV | 50 kW | ~83 min (10-90%) | ~65 kWh | City driving only |
Breaking Down the Models
Silverado EV: The Charging Champion
If you need to cover serious miles, the Silverado EV is your truck. In Car and Driver’s independent testing, it was the fastest-charging EV they’ve ever tested, with an average charge rate of 198 kW and a peak of 315 kW . That means you can add 100 miles in just 17 minutes—enough to get you back on the highway while you grab a snack . The official specs from the U.S. Department of Energy also confirm its 350 kW capability .
Equinox EV, Blazer EV, and New Bolt: The Mid-Tier Group
These three models all land in the 150 kW sweet spot. That’s a very solid speed for a modern EV.
- Equinox EV: Officially rated at 150 kW, which Chevy says adds about 77 miles in 10 minutes . However, independent testing found it took about 40 minutes to go from 10% to 80% on a 250 kW charger . A key point: the Equinox needs a charger that can deliver 500 amps to hit its full 150 kW speed, which isn’t always the case .
- Blazer EV: Chevy claims the RWD model can get up to 80 miles of range in 10 minutes of fast charging . The U.S. Department of Energy lists its DC Fast charging at 150-190 kW depending on the model .
- 2027 Bolt EV: This is the redemption story. The old Bolt’s 50 kW speed was its biggest weakness. The new one now matches the Equinox at 150 kW, meaning a 10-80% charge in about 25 minutes . It’s also Chevy’s first EV with a built-in NACS port for easy Tesla Supercharger access .
Previous Bolt EV/EUV: The Slow Charger
There’s no sugarcoating it. The previous-generation Bolt and Bolt EUV max out at 50 kW on DC fast chargers . In real-world testing, it took a painful 83 minutes to go from 10% to 90% . It’s a fantastic city car, but it’s not built for frequent road trips.
Does Charger Power Really Matter? (The Equinox EV Example)
Here’s a surprising twist: A 350 kW charger isn’t always faster than a 250 kW one. InsideEVs tested an Equinox EV (which peaks at 150 kW) on three different chargers: a 150 kW, a 250 kW, and a 350 kW unit .
The results? The 250 kW Tesla Supercharger was actually the fastest, completing the 10-80% charge in 40 minutes. The 350 kW unit took 41 minutes, and the 150 kW charger took 44 minutes .
Why? Because the Equinox EV needs 500 amps to hit its peak. The 150 kW charger couldn’t supply enough amperage, so it was capped at around 96 kW. The lesson? A higher-kilowatt charger doesn’t guarantee a faster charge if your car can’t ask for the power in the right way.
FAQ
1. Which Chevrolet EV charges the fastest?
The 2025 Silverado EV is the fastest, with peak charging speeds of up to 350 kW . In independent testing, it averaged 198 kW and could add 100 miles of range in 17 minutes .
2. How fast does the 2027 Bolt EV charge compared to the old one?
The new 2027 Bolt EV charges over 2.5 times faster than the previous generation. It now peaks at 150 kW, going from 10% to 80% in about 25 minutes, compared to over an hour for the old 50 kW version .
3. How long does it take to charge a Chevy Equinox EV?
The Equinox EV has a peak charging speed of 150 kW . In real-world testing, it takes about 40 minutes to go from a 10% to 80% state of charge on a fast charger .
4. Is the Silverado EV really that fast at charging?
Yes. The Silverado EV is one of the fastest-charging EVs on the market. It can handle up to 350 kW and has been tested to add 50 miles in just 9 minutes .
5. Why is the old Bolt EV so slow at DC fast charging?
The previous-generation Bolt has a maximum DC fast-charging speed of just 50 kW . This was a limitation of its older battery architecture, which was designed more for efficiency and affordability than for rapid road-trip charging.
6. Does using a more powerful charger always mean a faster charge?
No. As seen with the Equinox EV, a 250 kW charger can be faster than a 350 kW one if it provides the right amperage for the vehicle’s battery. A car can only accept power at its maximum rated speed .
7. What is a “10% to 80%” charging time?
This is the industry standard for measuring DC fast-charging speed. It’s the time it takes to charge the battery from 10% capacity to 80% capacity, which is the sweet spot for road trips because charging often slows down significantly above 80%.
