New charging stations going in are 150-350 kW watercooled CCS. I've been to the 350kW one at Baker, check Plugshare for an I-Pace.
CHAdeMO cars are obsolete when sold.
The idea that GM is not serious about EVs is laughable. Outside of maybe Tesla, GM has more engineers on Advanced Propulsion than any other company. And the world's largest battery lab. GM had a 'clean sheet' EV for the public using aluminum aerospace technology and went over 180mph at Bonneville. The world was not ready for it. Tesla years later, put together a kludge called the Roadster which is now virtually orphaned 7 years after production stopped. Today, Tesla struggles with blended brakes, absorbing abuse, cost of repairs, service infrastructure, exaggerating specifications, selling untested or unavailable features, 11 years after they started. Tesla is not guys working in their garage on a limited budget. They were funded to absorb losses for a decade straight, and received direct corporate tax incentives, and even California is kissing their arse. Normally non-union automakers are ran out of the state. Tesla is even set up in a factory that California worked hard to close down (GM/Toyota), but CA subsidized it. It's a Bay Area thing. Hypocrisy or die is the state motto now.
So a pure electric company with same capitalization as General Motors, that can lose money a decade at a time, isn't really ahead of GM from a technical perspective. Super Cruise actually works. So does Cruise. The Bolt exceeded it's EPA range when they threw a handful of keys to journalists and gave them a destination that was out of range. Everybody made it. So you'd THINK Tesla would do the same. Nope. In fact some folk are questioning the 310 mile range, especially on the AWD and P cars. Zealots claim the car gets over 5 miles per kWh in normal freeway driving in the winter. Seriously, they post that. Others are puzzled why they are getting 240 miles of range when driven normally.
