The chargers will be open to every car manufacturer and will use the universal CCS2 charging infrastructure.
This is very impressive, I just saw a Youtube video from Sweden about how insanely fast these new BYD cars charge 10-70% in 5 minutes!!!
Meanwhile the new Tesla model Y that supposedly charge at 250 kWh, has one of the worst charging curves in the market, and drops off to only 100 kWh already at 35% charge level!!
The new Tesla cars are actually worse than the old ones, because Tesla is using their own inferior battery design made for the Cybertruck, that Elon Musk used to rave about how amazing would be, but gave them so many problems to manufacture, and apparently this never got completely solved.
Anyone who think Tesla is still a market leader or even just still a good option must be unaware of how bad Tesla is now compared to the competition. Tesla did some cool things early on, but they are nowhere near what their marketing is claiming.
Do they come with a nuclear power plant embedded? Jokes aside, how is the electricity network going to handle such loads?
You have to consider that the amount of power needed is the same, it is just delivered quicker for the individual car.
But spread among thousands of cars it all evens out, making the power delivery required mostly the same.
Slower charging just means more cars are charging at the same time, and 50 cars charging at a lower rate is the same as 10 cars charging 5 times as fast, but also only a fifth of the time.So for the network it’s the same, it’s only for the individual charger that there’s a real difference.
No, it’s most definitely not the same for the network. The sizing of everything in electrical infrastructure - generators, transformers, cables, protection devices - is bound to the current going through them. When you deliver the same energy in a much quicker time, you can only do so by increasing the current. Which means that, unless people are charging in low demand hours (e.g. at night), your infrastructure will either buckle or “shed loads”. Load shedding is when a circuit is dropped to prevent the overall network to brownout. Better not place the chargers in the same circuit as hospital and homes for the elderly!
False, the chargers have transformers, and I bet charging stations with 20+ chargers have local transformer stations too.
For one transformer station to supply for instance 12 chargers at 100 amps each or 4 at 300 amps each is both 1200 amps.When you deliver the same energy in a much quicker time
You obviously completely failed to understand my explanation that this is not what is happening on the scale of charging stations with many available charging slots.
Obviously these 1,5 MWh charging stations will not be availbale at you local grocery store, they are part of bigger installations with probably already around 20 charging slots of 300-400 kWh charging capacity.
I’d assume charging stations number is the same with some or all at higher power. But yes, reducing the number would solve power demand.
That’s a very different issue, that would be caused by the increasing number of EV. And that issue would be the same with or without faster charging.
Without the faster charging, obviously more stations are needed.
As I already stated, the charging speed has very little impact on the cumulative load on the grid.It’s not exactly the same. Space where you put charging stations is usually limited. With higher power chargers, the entire charging infrastructure will require more power. Which means “thicker” cables. Sure, globally the power requirement are the same.
lots of solar a and large batteries adjacent from pics I’ve seen
still, need to build out as we “electrify” everything, it’ll be chicken egg, egg chicken for some time.
Hell, KFC in China is doing a JV with BYD and high speed charging, wjo knew that was a problem to solve.
Probably the same way it’s handled when someone builds a new factory.
Some of the high power ones have batteries that they essentially use as a buffer. Recharge them when idle, then use them as extra capacity when charging cars.
Apart from that, I’m not sure. Probably the same way other consumers are handled How much peak power does a large apartment building, office, or factory use?
the devices can be powered by on-site battery packs topped up by solar panels.
I believe this is the case for a lot of the very fast chargers, it’s easier to install batteries pack to smooth the consumption rather than upgrading the grid to handle the occasional peak consumption.
Pushing 1.5kW is going to get dangerous when the chargers and cars age.
1.5MW, not kW.
Is it actually “pushing”? I’ve always thought the consumer is “pulling”.
Yeah, devices pull power.
The charger periodically tells the car the maximum power it can provide, and the car knows to not ask for more than that (plus the charger will just cap it at its max).
Apart from that, it’s mostly like a regular electrical outlet. If you plug in a 50W desk fan, it’ll only pull 50W, even though the outlet can provide 1800+W
Why?
