This could be good, but as a EV owner I am not convinced that I need a recharging speed that is this fast. I own a Chevy Bolt ( known for its sloooow charging speed) and even when we travel longer distances and need to charge stopping for 20 minutes would be great ( thats a bathroom break and snacks) so I applaud the technology but I think pushing the envelope down this far is not what most people would need.

    There is literally no downside to having faster charging.

    I think fast charging negatively impact battery life because of the heat it produces. It would be nice to be able to choose the amperage we want for a specific charge, when we're not in a hurry.

    I would imagine they've considered batter degradation here. It could be that the approach they use doesn't cause significant damage to the battery.

    They actually tell you it’s better to charge it with the slow charger most of the time. The fast charger does have a negative effect on battery life. I don’t know how significant it is though.

    It'd be interesting to see what the difference is there. The ideal would be if you have a charger capable of rapid charging, and you can dial it down if you want to assuming there is a negative effect on the battery.

    Which is why i still think that the best solution at the moment is still battery swapping stations. That way you get the best of both worlds. Your vehicle is back at full charge within a couple of minutes (the only limitation is how fast the mechanical operations can be performed), and the batteries themselves can be charged as slowly as needed to preserve long term battery life.

    Explosions. Incredibly high amperage requirement. Unproven Chinese technology. There are downsides.

    If anything the fact that it's Chinese should be viewed as a good guarantee that it works. Not because the Chinese are inherently superior or can't make mistakes, but because China is a huge market and a product that has already been sold to and used by millions of Chinese consumers has effectively undergone more rigorous testing than almost anything else you can imagine.

    How much more "proven" can something get? There is no better test of a technology than it being successfully sold and widely accepted in a country as gigantic as China. This should be entirely uncontroversial, it is just simple math.

    The Chinese domestic market for everything EV related is incredibly competitive compared to what we have in the West. Most Chinese brands don't even make it out of China (because there are so many Chinese brands and because China itself is a sufficiently large market that they don't need to expand internationally to be successful) and those that do, do so because they have proven to be a cut above the rest.

    I accept these points if you exclude "Chinese" lol how does the nation of origin have anything to do with it?

    People say made in China stuff is cheap and unreliable. Bruh they make everything, not just the cheap stuff.
