How Long Does It Take To DC Fast Charge The 2027 Chevrolet Bolt? We Find Out

Why It Matters

Faster DC fast‑charging narrows the gap between affordable EVs and premium models, shaping buyer expectations and influencing charging‑network utilization.

Key Takeaways

• New 2027 Bolt peaks at 158 kW, three times older model.
• 0‑100% DC fast charge completes in under 60 minutes.
• Real‑world 10‑80% charge takes ~33 minutes, missing GM’s 26‑minute claim.
• Battery state‑of‑charge readings may be off by up to 4 %.
• Charging efficiency drops sharply after 70% SOC, adding only ~2.5 mi/min.

Summary

The video documents a full 0‑to‑100% DC fast‑charging test of the 2027 Chevrolet Bolt RS on a 350 kW EVgo station, highlighting the model’s upgraded LFP 65 kWh pack and next‑generation power electronics that lift its peak charging power to roughly 158 kW, three times the original Bolt’s 50 kW limit. Key data show the Bolt reaching 30% SOC in 10 minutes, 52% in 20 minutes, 70% in 30 minutes, and completing a full charge in just under an hour. However, the real‑world 10‑80% interval took about 33 minutes, falling short of GM’s advertised 26‑minute target, and the vehicle’s state‑of‑charge readout appeared 4 % low, likely due to calibration needs on a brand‑new battery. The presenter notes the initial surge to 150 kW within the first minute, a peak of 158 kW at four minutes, followed by a steep drop after six minutes, mirroring the charging curve of GM’s Equinox EV. The car reported 96% SOC at shutdown while the driver’s display showed 100%, underscoring BMS communication quirks during early cycles. These findings suggest the new Bolt offers a markedly faster DC fast‑charging experience than its predecessor, making it more viable for drivers needing quick top‑ups, yet the diminishing charge rate after 70% SOC and occasional SOC inaccuracies indicate room for GM to refine its battery management and charging algorithms.
