My impression is that EV technology is maturing and stabilizing somewhat. e.g. near 400V-800V battery packs, Heat-pump based cooling and heating of cabin and battery. battery preconditioning for fast-charge... 15%-80% in 20-30min for roadtrips...
The formula and main approaches have been identified. Whatever battery improvements happen will just get incorporated as they come.
No, it is not. It's just the current crop of cars, e.g. the 2025 model year. Now you get similar technology that had costed 50,000 EUR or more a few years ago, in 25,000 EUR cars. But if you look into the 50,000 EUR range, it's different. Take the Xpeng g7+ for example, which offers 20-80% charging in 10 mins at a price point of 53,000 EUR! Or the Mercedes CLA 250+ with a 500 mile range costing 58,000 EUR!
Charging technology is currently switching from 400 V DC to 800 V DC - but that's not just the cars, it's also the charging infrastructure, which has to be improved. First cars with 1000 V DC charging are already presented, and more importantly, 4C or 6C charging is possible now in some models (which means 4 times battery capacity in one hour, or 6 times capacity in an hour). And on the engineering side: ONE Cabot R&D in the U.S. has shown that you can fit more than 200 kWh with current cells into the battery compartment of current cars.
What might be true is that the current offerings on the BEV side are good enough for 96% of Norwegians, 68% of all Danes, 40% of Dutch people and 37% of all Finns.
