BYD says new fast-charging system could be as quick as filling up a tank

When will these cars have a breakthrough in terms of UI and privacy (let&#x27;s ignore the cost for a moment).<p>I don&#x27;t want to spend a shitload of money on an iPhone with wheels which doesn&#x27;t even come with all the privacy promises apple makes and which is full of dark patterns, subscription models, and proprietary interfaces (talking about apple carplay, android auto, feature allowing you to use spotify, etc. The mere fact the car has these makes me not want to buy it, even though I would never use them. Paying money to have a hardcoded e.g. spotify client in my car is encouraging exactly the wrong design practices.).

I live in Germany, which has its automobile industry being shredded into pieces by China, and it&#x27;s for a good reason though.<p>China is so ahead of the west in EVs, their battery tech, supply chain and also expertise is so amazing.<p>In China, you can buy even a car with swappable batteries. They are also extremely cheap in comparison to the West.<p>For people that live in the best Chinese cities and work in a white collar job, it&#x27;s very cheap as well. Cheaper than it is in America or Europe as the purchase parity there is much higher.<p>The West needs to drop the &quot;free markets economics&quot; and heavily invest and subsidize EVs, they are the future.<p>We can&#x27;t afford to wait 10 years and lag behind so much, China will end up producing all cars in the world and that&#x27;s millions of well-paid jobs.<p>Go to Brazil and you&#x27;ll see how many BYDs are everywhere. China will unfortunately eat the entire third-world car market, which has long been a good line of profit to US&#x2F;EU car manufacturers.

People in America and Canada where there is a 100% tariff on Chinese EVs don&#x27;t appreciate what they are missing out on.<p>For ~$60k you can buy vehicles like the Li Auto L9 that are nicer than a brand new Rolls Royce. The value for price you get blows other manufacturers out of the water.<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;shorts&#x2F;tjnq2usV51c" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;shorts&#x2F;tjnq2usV51c</a><p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=RwO-OcNUzyg" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=RwO-OcNUzyg</a>

I&#x27;d prefer standardized, swappable batteries. Imagine driving up to a gas^Wbattery station, you place your car at a certain spot and your old battery drops out and a new one is inserted and off you go, not even having to leave the car. The old battery is charged slowly, cheaply and safely, while you&#x27;re on the road again 5 minutes before that one guy still filling diesel.

Awesome to see BYD continue to innovate! I wish Tesla continued to push on powertrain improvements like this rather than making a triangle shaped truck.

&gt; peak charging speeds of 1,000 kilowatts (kW)<p>Obvious safety concerns aside, I really worry that we are losing perspective on what the grid is capable of and the possibility that distributed technology won&#x27;t get us to the ideal outcome fast enough.<p>The power plant nearest to me could only handle ~1000 instances of this kind of charging before it is completely saturated. The transmission (transformer) infrastructure is the biggest bottleneck. Even if Entergy built several additional gigawatts of capacity on their existing site, they&#x27;d have no way to deliver it. Tesla would have to install supercharging stations in their switch yard and figure out how to operate at much higher supply voltages.

Meanwhile, there is unidentified source of lithium pollution in Beijing, causing 20 times higher concentrations among pregnant women and newborns[0]. Guess everything has its cost, even for clean energy.<p>[0]: <a href="https:&#x2F;&#x2F;www.scmp.com&#x2F;news&#x2F;china&#x2F;science&#x2F;article&#x2F;3301053&#x2F;unusually-high-lithium-levels-among-beijings-pregnant-women-and-newborns-study" rel="nofollow">https:&#x2F;&#x2F;www.scmp.com&#x2F;news&#x2F;china&#x2F;science&#x2F;article&#x2F;3301053&#x2F;unus...</a>

1MW charging? wow, that&#x27;s a lot. I hope they have a suitable explosion containment pie dish in case something shorts

The comments here are more interesting than the article.<p>Often on HN that statement would mean that someone with relevant technical experience has commented, but not this time.<p>Instead the comments on a fairly mundane incremental improvement in technology are full of concern trolling, whataboutism, nitpicking and cope.<p>This suggests to me that people are starting to absorb the information that China is ahead in this area of tech and they are emotionally uncomfortable with that reality.

&#x27;as quick as filling up a tank&#x27; is a bit exaggerated (5 min for 250 miles) but I guess it&#x27;s impressive that it&#x27;s getting to the same order of magnitude.

Battery charging&#x2F;discharging speed is limited not by capacity but by current relative to capacity. Li-ion batteries can generally be recharged in constant current mode without significant degrading up to &quot;4C&quot; - 4x its mAh rating, above a low threshold below which it&#x27;s not yet safe to charge at full speed, and below ~80% where it&#x27;s no longer safe to charge with constant current but charging has to switch to low current constant voltage mode.<p>Cutting down charging time to below 1&#x2F;4th standard Earth hours require material science breakthroughs(hard). While this system might be useful for charging a 4MWh train packs, or a 1MWh semi pack with a not insignificant degradation penalty, this does not accelerate charging for most EV users even if this was to be deployed widely.

5 min charging would be a game changer as it reduces the need for larger batteries which lowers cost and weight again impacting cost.

Pipe dreams, charging with extreme wattage is not where the research should be concentrated at.<p>&gt; peak charging speeds of 1,000 kilowatts (kW)<p>Who will deliver this in the next decades at scale? In western EU you find 150W poles at most, and that&#x27;s like 10 stations&#x2F;120km.

The article does not really say anything about the system, but I wonder how this differ from MCS [0] which allows up 3.75MW theoretically and should (fingers crossed) begin to slowly roll out in Europe for trucks this year.<p>[0]: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Megawatt_Charging_System" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Megawatt_Charging_System</a>

That&#x27;s 1000 amps at 1000 volts.

Won&#x27;t too much fast charging deteriorate the battery health faster?

1 MW charging. Impressive if the battery can handle that on the long run. Though I guess for a lot of users it will not be used often, only on long vacation trips or similar.
