Comment on BYD is testing solid-state EV batteries in its Seal sedan with nearly 1,200 miles of range
jonne@infosec.pub 2 days agoThe existing range was already good enough for most. I feel like you could read this as they could build a car with the same range with only half the battery pack, which saves on cost and weight.

And people still won’t want them because they can’t go on long trips without extra effort. Until charge times are on par with gas you need the range to get people to buy them.

So most petrol pumps do about 38l a minute for cars, even in a car with a big tank that’s less than 2 minutes. Now you have to pay, either before or after depending on the pump, 5 minutes if you have to go in a bit less if you can pay at the pump. 7 minutes max assuming no queues?
I just do not see charging to be even in the same ball park unless:
All cars and chargers support OCPP so you just have to plug the car in and it starts charging no messing with apps or payment cards.
Batteries reduce in size with the increasing efficiency so you are charging less kw but this does not impact charging speed as at the moment more cells means more speed for longer.
People accept that charging to 100% when trying to charge quickly just isn’t going to work, the last few percent are always going to be much slower. It’s quicker to charge twice to 80/85% than once to 100%
Best time can do currently is about 40kw in 18 minutes, even with halving the amount to charge its going to be 10 minutes but then its only adding about 160 miles of range. We’d need to get to double that of range for most people, pretty significant jump.
Personally I’m happy having to stop for twenty minutes or so for a comfort break for me while it charges every three hours or so. Not having to go to the petrol station while at home is also a massive perk.

Yeah, I currently still have a petrol car, but I feel like an electric car would work out better with my current usage. I basically never do long trips, so every month or so I have to go out of my way to fill it up. If I had an electric car I could just plug it in at home, and if I was feeling fancy I could even set the charger up to only charge with excess solar so it would be completely free.
And finding a charger on a long trip and stretching your legs for about 20 minutes definitely seems better than stopping at a stinky petrol station.

If you can charge at home especially on solar they make so much sense. I would not switch back for any ICE as my main car even if i was gifted a non returnable Ferrari lease.

People here screech about them, but PHEVs are great and instead of subsidizing one giant ass ev battery we could offer more incentives for PHEVs. But nobody wants to optimize for now vs the fancy no gas cars by 20xx slogan politicians want.
You get big BHP numbers, you still drive 98% of the time on electric, and just gas up for longer trips. The maintenance on them is also greatly exaggerated.

PHEV for certain situations is still the best choice, but its more a limitation of the charging infrastructure than anything else. In some countries this is not a quick problem to solve so PHEV has a use for quite some time.
PHEV was very much a stop gap when batteries were even more expensive, performed by third parties (so losing that profit margin as well) and production limited so they reduced the size of the battery to keep the car affordable. Long term they are a dead end outside of specialised use cases.
A lot of PHEV owners do not bother to charge regularly as the small battery needs daily charging.
They have higher engine wear due to the engine being used more aggressively when cold as battery was used for the start of the journey.
You are also carrying around an entire ev and an entire ice, with additional complexity to meld the two together. It’s just not smart design, KISS after all.
I much prefer range extending engines like on the i3 that act as direct generators as a concept for properly remote travel. Although the tech is far far from perfect and advances in battery, such as these solid state batteries, look to make it superfluous.
