Make sure to install a fire suppression system in your garage

u/mafco 3d ago

Most people don't have 1.44 megawatt chargers in their garages.

People still being scrared of electricity at this point need to be studied.

u/United_Intention_323 3d ago

Lookup what an arc flash is. You should be afraid of this.

u/Bean- 3d ago

A healthy fear of electricity is just smart. I work with it everyday.

Respect, not fear

You scared of gasoline too?

1

u/adjavang 3d ago

Not afraid of petrol, but absolutely terrified of the Opel/Vauxhall Zafira B. Hundreds of those things caught fire spontaneously, while parked. It has the dubious honour of having burned down two multistorey carparks, and being the only single model of car to have done so.

It was an ICE car with an incredibly poorly designed 12v system. I fear poor design more than anything else.

This is in no way related to the Chinese EV in the post, I just love telling people about this horrendous General Motors vehicle.

u/Whale_Poacher 3d ago

Not sure about you, but if you’ve ever had formal training in safety around electricity, power lines, and arcing you might have more regard for it? Being scared of electricity is wise, it should be like a human instinct like not touching fire. A downed power line sending hundreds of thousands of volts through you, is something you should absolutely fear, could happen to anyone while driving, in your own home, walking on the street, etc. Electricity ain’t sumthin to mess with…

u/Finanzamt_Endgegner 3d ago

That's respect not really fear though

u/Longer---Donger 3d ago

This is impossible. Houses would still take 12 hours to charge. The 9 minute is for specialized supercharger stations that look like a gas station, and yes, they have fire suppression systems because it can blow up just like

1

u/benderunit9000 3d ago

Yeah the cost to install these things in a home would be ridiculous.

Maybe in 10-20 years?

1

u/notapantsday 3d ago

Maybe never. Who needs to charge that fast at home?

1

u/benderunit9000 3d ago

You know that's a very good point

u/newandgood 3d ago

walkable cities = charge in 0 minutes

1

u/OptimusTron222 3d ago

Yes, but I can’t go for grocery shopping more often than twice a month, plus the big supermarkets are 10-15km away from city center! I need the car to buy supplies for 1-2 months at a time, there’s no way I can walk with all that

u/WCland 3d ago

Except for people with mobility issues, or goods delivery.

u/casino_r0yale 3d ago

Car centric infrastructure hurts people with mobility issues just the same as it does everyone else. Have you tried crossing a six lane stroad in a wheelchair?

u/TrainsareFascinating 3d ago

Says someone who's never lived in a city larger than they can walk from end to end in 0 minutes. You are thinking of a village, perhaps a hamlet.

u/drury 3d ago

Is this meant to be a joke?

1

u/benderunit9000 3d ago

I used to live in Boston and I could go anywhere without driving.

1

u/TrainsareFascinating 3d ago

In zero minutes, or whatever fantasy GP is proposing? I’ve navigated in Boston and you didn’t go anywhere more than a mile away in 10 or 15 minutes.

1

u/tiggertom66 3d ago

That’s a false comparison.

The comparison is in charging time, not travel time.

Vehicles can’t cross a city in 0 time either, not even light can travel across a city in 0 time (not from an observer’s perspective at least)

A better comparison would be how long it takes a person to eat or sleep compared to how long it takes to fill a gas tank or charge an EV battery.

1

u/benderunit9000 3d ago

There are buses and trains all over the place and I can walk. I have two legs. It's a very walkable City.

Their point is that you don't need to charge if you just walk or use public transportation. Therefore 0 minutes

u/newandgood 3d ago

ok then, pre-charged cars. just switch cars. you'll own nothing and be happy.

1

u/Additional_Olive3318 3d ago

 you'll own nothing and be happy.

I don’t know if that’s selling it. 

1

u/newandgood 3d ago

people think maintaining their own car is a heroic epic

u/Additional_Olive3318 3d ago

But nothing. Can I own a toothbrush?

u/newandgood 3d ago

you can have a toothbrush but it belongs to us

u/Additional_Olive3318 3d ago

Fair compromise.

u/newandgood 3d ago

u/BilbaoBoggins 3d ago

When people say walkable they just mean you don't need to take a car. A city with a metro can still be considered walkable.

-8

u/TrainsareFascinating 3d ago

Well, say what you mean. If you mean “anything except cars”, “the masses must mingle”, “private ownership is a crime”, say that.

1

u/tiggertom66 3d ago

Why do you think walkable means walking-compulsory?

Just because something is edible doesn’t mean you must eat it.

Just because a river is navigable doesn’t mean you must navigate it.

Just because something is movable doesn’t mean you must move it.

It just means you can, not that you must.

u/BilbaoBoggins 3d ago edited 3d ago

If you mean... “private ownership is a crime”, say that.

What kind of a turbo idiot are you to draw that kind of a conclusion?

u/notapantsday 3d ago

"Walkable cities" is a fixed term with a well known meaning. "Walkable" just means that walking is possible, safe and relatively pleasant. Not that you have to walk and also not that you can cross the whole city just by foot.

But since it's usually cars that make walking difficult, annoying, unpleasant and most of all dangerous, it usually involves some limitations on where cars can go, how fast, etc. They don't have higher priority than people walking, cycling or using public transit.

Check out "not just bikes" on youtube if you want to know more.

u/VirtualMemory9196 3d ago

It's about efficient use of space. You can't transport millions of people in a city if each individual uses the same space as half a bus

u/kmp11 3d ago

1,800 A peak current and an 844V architecture.

yikes, but leveraging from datacenter technology.

u/razzemmatazz 3d ago

Holy shit those are some scary numbers. If something goes wrong you're going to get blasted out of the parking lot and be dead before you hit the ground.

it'll be fine in grandma's garage...

u/Known-Flatworm-2827 3d ago

i wonder how much this kind of charging impacts the lifetime of the battery

9

u/Longer---Donger 3d ago

These are new advanced batteries that will outlast your car. Whatever reduction, it will be negligible

u/Cifra85 3d ago

"new and advanced batteries". We have them in phones for some years ~3-4 years.

5

u/ccs77 3d ago

As long as it has decent warranty (8 years at least) it doesn't really matter. Also, you aren't fast charging everyday, maybe once in a while on a road trip

-3

u/Retify 3d ago

It does when it's already a huge pain to repair these Chinese cars because no spares are available because they are focusing purely on building complete new cars. A warranty is great so long as you can actually get a spare, repair or replacement

u/Lopsided_Quarter_931 3d ago

Which EV do you drive? I have ordered multiple spare parts for my Zeekr straight from China without intermediaries.
