Some of the EV "experts" are skeptical on these 5 minute charge times that the Chinese are claiming. If their claims are valid, that would be good news.
I'd almost bet my life the breakthroughs are or will be real and they will come from China.
They have a government that is happy to win slow and steady uninterupted 20-50 year battles, we have one that completely changes course every 2-4 years and our newest position is we want to focus mostly on coal for our homes and gas for our vehicles.
I'm not saying I want to live in a society like China's but BYD plus Chinese government's consistent approach is a massive advantage over our legacy car companies in bed with oil industry and a government that fights against EVs 50% of the time. Tesla could easily have been America's BYD with a more consistent government and almost got there even without it, but there are countless reasons Tesla did what the US legacy manufacturers did not and history will likely show that to be shortsighted.
This thread of trepidation is perhaps the biggest advantage China has in their process of soon dominating the American, European and Japanese auto industry. A huge % of Chinese drivers are first or second generation car owners. They don't have a century of irrational sentimental attachment to the internal combustion engine, it's not at all part of their idea of what makes their country great or what makes a man 'manly'. That's a massive edge for easy adoption, it's not "new" for many people, it's simply their first family car and the only thing they'll ever know.
