GM’s Bolt: The Fast-Charging Outlier Fueled by a China-made LFP Pack
GM’s Bolt uses a Chinese-sourced lithium-iron-phosphate (LFP) pack that runs at a higher nominal voltage (near 400V), enabling a 10–80% charge in about 26 minutes—faster than GM’s Ultium-pack models that run around 290V and rely on high current. This speed comes from the Bolt’s LFP chemistry and different pack architecture, but the article notes there’s a catch to the Bolt’s approach that’s explored in a fuller drive review.
