Not in the Bolt, the battery wasn't designed for that high of a charge rate. 70kW is the maximum rate even for short periods. That value should actually decrease over the life of the battery but I don't think GM went that far in their programming. You could push it harder if you managed to keep it cool, but you're going to risk accumulating dentrites pretty rapidly.This constant demand for punishing a lithium battery with massive 2c -3c charging speeds. Sure it can be done, GM could allow 150kw charging speeds and then deal with the much faster degradation that it ALWAYS entails. The Bolt battery coolant design just isn’t capable of providing the consistent, even, cooling across the 288 cells that’s required to cram 150kw into a 66kwh battery. It was designed to be adequate for moderately fast charging and keep degradation in check. Get used to it.
