    I will get excited once this leaves the lab and is actually on the market.

    Oh, wait…

    What the fuck does 5 minute charge mean? Zero to full in 5 minutes? For that big of a battery I believe that is not physically possible

      This is one of those rare situations where reading the fucking manual article helps:

      A standard home charger trickles power overnight at roughly 7 kilowatts, like a garden hose. A Tesla Supercharger—long considered the gold standard of public fast-charging—maxes out around 250 kilowatts. BYD is unleashing six times that amount of energy, effectively hooking the car up to a high-pressure municipal water main.

      During a live demonstration onstage, BYD plugged in its new Han L sedan, making the battery jump from 10% to 80% capacity in exactly six minutes and 30 seconds.

        The amperage to do that is insane, either you’re dumping power from town sized feeder lines (seriously limiting where you can place those chargers) or you are charging capacitors to charge the car (wasting energy and limiting how often you can charge a car at those speeds)

      Which part of physics prevents that exactly?

        The main problem is having a charger with enough power to fill the battery that fast. But it’s more of an infrastructure problem.

        Also the numbers given are usually for a 80% charge. I don’t know if it’s the case here, but probably.

          I believe those chargers are battery to battery, not grid to battery. You don’t need 2.5Mw connection directly to the charger. You charge the charger’s battery at normal speed and then pump it into the car rapidly. This means that you can charge only couple of cars in a row at that speed.

      Another question: is how many charge / discharge cycles are possible?

      Usually the faster you charge a cell, the fewer times you can do so.

    I didn’t see any mention of which standard was used to calculate range so I’m assuming CLTC.
