If you're interested in learning how and at what percent charge a Bolt tapers during a fast charge, or how much time it would take to get there (ballpark, because my timings are based on optimal conditions), this video I made with the help of some kind data collectors is a good entry point to understanding.
Here's the same thing, but at 125 Amps, which will have the same tapering graph shape as 150 Amps (aside from the initially higher power of up to potentially 55kW, the Bolt's max):
Thanks, this is really helpful information. I don't have a Bolt (yet), but am strongly considering one soon and would have some long drives to make if I did.
No problem! There's actually another speed level higher (55 kW) that I posted in a different thread. You can find it here. That's the highest power at which the current model year Bolts will charge.
How do these charging profiles change under sub-optimal conditions? Like when it's really cold outside? Below freezing ... If we get a Bolt, reduced winter range will necessitate a mid-trip DC charge. But hopefully that wouldn't be necessary unless the temps are much below freezing.
The current the Bolt will accept is definitely effected. Whether or not the percentages where the tapers occur are effected, I do not know for sure. But with lower ambient and battery pack temperatures, you are going to see less current coming into the battery. There's some useful data on this over at the chevybolt.org forum. Check out some of the posts from user Vertiformed. Pretty insightful. https://www.chevybolt.org/threads/fast-charging-experience.31517/post-475581
