The 2027 Chevrolet Bolt Charges Three Times Faster Than Its Predecessor. Here's What the Data Shows.

The 2027 Chevrolet Bolt's most significant change is not visible from the outside. The battery holds the same 65 kWh of total capacity as the original, but a new LFP chemistry and next-generation power electronics shared with the Equinox EV have tripled the car's DC fast charging ceiling. Where the original Bolt was capped at roughly 50 kW, the 2027 version peaks at 158 kW. State Of Charge tested a 2027 Bolt RS on loan from Bridgewater Chevrolet at a 350 kW EVgo station, running a complete 0 to 100 percent charge session. The car added 78 miles of EPA-rated range in the first 10 minutes, reaching 30 percent state of charge. At the 30-minute mark, the battery was at 70 percent. The original Bolt needed 55 minutes to reach that same threshold. EPA-rated range for the 2027 model is 262 miles. The base version starts under $30,000.

The original Bolt was a credible affordable EV when it launched, but a 50 kW fast charging ceiling became increasingly indefensible as the market moved forward. The 2027 version fixes that specific problem. State Of Charge notes several caveats on this initial test: the car had only 22 miles on the odometer when it arrived, meaning the battery management system had not yet fully calibrated its state of charge readings. This appears to explain the unusual end of the session, where the car stopped charging at a displayed 96 percent while the driver screen showed 100 percent. GM's claim is 10 to 80 percent in 26 minutes. The test recorded 33.3 minutes for that same window. The tester attributes part of the gap to the fresh battery calibration and a CCS adapter required at the EVgo station. A follow-up test with a higher-mileage car is planned.

The charging curve shows the Bolt drawing its full 400 amps almost immediately after plug-in. Power climbs to 158 kW within the first six minutes, then drops sharply before stabilizing, a pattern the tester has seen on his own Equinox EV and suspects is the programmed curve rather than thermal derating. Range replenishment runs at 8 miles per minute in the first 10 minutes of charging, 5.6 miles per minute in the second 10, and 4.5 miles per minute after that. The tester's recommendation is to unplug around 40 minutes. Beyond that point, the Bolt adds roughly 2.5 miles of range per minute and the return on waiting drops significantly. For a 10 to 80 percent session, the car averaged 94 kW and delivered 45 kWh to the pack, adding 183 EPA-rated miles in 33.3 minutes. From 0 to 100 percent, the session clocked 53 minutes total, compared to more than two hours for the same charge on the original Bolt.

Bottom line: For most Bolt buyers who charge at home and use DC fast charging a few times a month, the 2027 car is more than capable. If you road trip frequently and time at the charger matters, faster options exist at similar price points. But the slow ceiling was a real problem on the original, and this version no longer has it.
