Car Tech 101: How to charge an electric car while demystifying the tech | Cooley On Cars 

Cooley is amazing. Very clear, articulate and straight to the point.

RAYLEGEND "unbox a box" lmaooo

you could be us average guy or u save rage guy...lol

@@philtripe WOW! I have used "usaverageguy" for about 12 years now. And I never saw that. You must have a wonderfully twisted view of the world. Thanks.

Agreed, I've been subbed to about 5 different EV channels for about last 3 or 4 years, and I only now (after watching Cooley explain it) understand the differences between J1772, CCS, and Chademo.

AC, DC, BC ?

Fast charger companies in Europe says is that Tesla haven't used the exact standard for the handshake communication in the Model 3. Most likely due to their own supercharger network is just plug and play. So if they will change this, they'll have to reprogram every supercharger to update to this new handshake. Shouldn't take long, but I'm sure it will change!

You can't blame them.. they are leaving the way to innovation without any profits.

Nonsense, Tesla designed and installed these chargers long before others did. So they are the ones that decided on another charger-plug.

Still saying that after they start selling .5 million cars/year? Like in 2020?

Atleast your not a fan boy but great for them keep on screwing your people over with a smile on there face perfect

Because we all know government intervention is the way to get things done... Except everything they touch turns to garbage. Just leave to the free market, if it's that important and enough people want it it'll happen

​@@jeremycastro8223 You see the thing about free market is they aren't beholden to the people but share-holders and the bottom line and will always try and take the avenue the yields the greatest profit consequences be damned. You wouldn't have clean drinking water, breathable air in the vast majority of major cities or any form of consumer protection. And there would be many times more monopolies then there are today. We need government regulation to keep companies honest. Do I think the government should be giving out bail-outs? No . But it's important to realize these companies won't act a lot of the time without over-sight.

BigHeadClan or just better names for them, except Tesla, SUPERCHARGER rocks!

@@bikesqump Hah it could be named the Chargematic 2000 and I'd be okay with it so long as we only had a single port to use and didn't need to carry around adapters. It should be like USB, a single port for pretty much everything.

@@BigHeadClan USB-A? Mini USB? Micro USB? USB-C?

IKR. 90KW what??? 22KW is max for Tesla S or X with dual internal chargers. Everything else is 7.2KW or less right now.

Correct me, if i wrong, but Mode 2 in both EU and US is 1-phase AC ~230V*32A current - 7.2kW with loses. Pretty decent. Mode 3 in EU is 3-phase AC ~400V*60A - 22kW, in US - idk, Type1 connector doesn't allow DC, and US grid system rarely provide 3-phase. Mode 4 is supercharging, as described in video.

@@Volodimar in the US, level 1 is 120 volts 12 amps single phase. Level two is 240 volts up to 40 amps or so, depends on the vehicle, single phase. Level 3 is DC fast-charging.

Completely agree. When he said level 2 goes up to 90 kW I was like "uhh what?". CHADdeMO in the US goes up to 50kW which is considered level 3.

I'm still fricken confused. EVs gonna need to STANDARDIZED their plugs and charge speeds. Prefer the fastest charge. How long does it take to fill a 25 gallon gas tank? That should be the standard time it takes to FULLY charge all EVs. Except Semis. They need 300 gallons of diesel fuel. So how long does it take to fill those semis should be how long it takes to charge those EV Semis. Faster would be better. Time us money. Getting stuck in traffic sucks a lot if time.

That would be a mistake as his numbers are wrong.

I was learning everything until that moment.

=D

Dude seriously.. there I was droning away and BOOM! Eyes wide open

Glad it was informative for you.

Perhaps integrate the data standard into an OBD III or OBD-E. Then it's just a matter of physical adapters for where the pins sit in the socket, until a dominant plug takes over.

This is why adaption rate be so slow aint going to do sh £t to slow global warming

Totally agree. I charge my 2013 Volt by 110v every night since I bought it - works great, can plug it anywhere and is super convenient.

Agree as well. I've had my Focus Electric for more than two years using L1 at home. Even when I upgrade to a longer range car in a few years, I see little need for L2 because if I really need a full battery fast, I'm going to drive down the street to the L3 fast charger.

Repeat after me: 120V. 120V. 120V. If you're getting 110V, call your power company, somethings wrong.

@@johnrielley7756 AC voltage varies. It's ok if it goes down to 110v because that's the lower limit on AC devices. My Lv 1 charger works on 110v (my grandma house) and 118v (my house)

Yep, it varies from -120V to +120V, 60 times a second ; ) The power companies established the 120V standard back in the 1930s as part of the Rural Electrification Act. You don't have 110V outlets, you have 120V outlets. If your grandma has 110V on her outlet, there's something wrong.@@AntonioCunningham

Widespread Level 2 in US is 10kW, while 16kW is also doable on Tesla. Most cars can do 7kW, that includes basic Model 3. 7kW is actually what everybody wants as a MAXIMUM. 32A amps on 240V. That includes whole world, not just US.

J1772 is the name of the plug and it works for Level 1 and Level 2. It cones down to the actual voltage supplied by the charger.

Tesla sells an adapter for CHaDMo to Tesla. I think the experts that he talked to were referring to the CHaDMo adapter but didn’t make it sufficiently clear.

That would mean 'working with' whatever number of charging providers are out there. Unless, you leave it to a semi-state service like what Ireland has.

@@toyotaprius79 Which is the ideal case. Just like petrol and diesel cars, you don't have to worry about the nozzle not fitting into your car, just turn up to whichever gas station you prefer and fill your tank up

@@toyotaprius79 it's called use your debit card like literally everywhere else for everything else. Just stick a goddamn pin pad an it and a price display geez it's not a difficult thing gas stations all have that.

Aside from the Tesla network it is fairly standard. The CHADEMO connector is on the way out in the U.S. as most manufacturers are siding with the J1772 / CCS standard. With the J1772 / CCS connector you can charge at Level 1 / 2 / and 3 (DC FAST if equipped in the car). But I agree, all PAID charging should be standardized though one app and / or payment method.

I don't know where Mr. Cooley gets that 90kW maximum for Level 2 charging, since most level THREE charging stations can only deliver 40 or 50kW. 90kW from 240V would mean about 380 amperes in the charging cable. The cable in my garage gets pretty warm just delivering 28A into my LEAF. But the battery capacities for EVs are generally in the 10 to 100kWh range. The initial LEAF was about 24kWh, current models offer 30, 40 (and soon 60) kWh, the Mitsu iMiev was 16kWh, the Honda Fit EV was 20kWh. Tesla battery sizes are generally in the 60 to 100kWh range. To get from amp-hours (or milliamp-hours) to watt-hours, you need to know the battery voltage; watt-hours are equal to amp-hours multiplied by battery voltage. The mobile battery you're talking about is probably one cell, which would have a voltage somewhere around 3.5V (kind of hard to say, because the voltage varies throughout the charge cycle). An EV's battery is built from a large number (about 100 or so) of cells all connected in series, and without knowing what the pack voltage is, it's hard to relate amp-hours to watt-hours.

@@levenkay4468 Thanks for the reply. So can a fit be charged to max using a 20KW charger in 1 hour?

@@Yathuprem It would, if its battery could accept the full 20kW even when it's very close to full. Most (all?) EV battery controllers reduce the charging current as the battery approaches a full charge. And as Mr. Cooley says, an EV's AC charger is part of the vehicle's equipment. A Honda Fit came with a 6.6kW on-board charger, so that's the maximum the car will take from an AC mains connection, even if that connection (the "EVSE") has a 20kW rating. And the Fit did not have any provision for DC "fast charging". Honda's 2012 web site speaks of a three-hour recharge time with a suitable 240VAC supply.

@@levenkay4468 now i got it. Thanks man

Definitely agree Charles. It's worked great for my life since I drive less than 30 miles a day most days. Even with longer trips, I can still make up the difference in a day since it's not imperative to leave the house with a full charge.

When you charge a leaf from 20% to 80% overnight on a 110 is perfect!!

It takes time for YT to update view count, especially when videos are first released.

He's your spirit-father.

One word, cost.

might as well get 40A with NEMA 14-50 outlet. 10KW charging for future EV

@@danwat1234 that the ticket..I charge my i3 in less than 3 hrs

Eventually we might see a standardization across the board, but just like there are different power delivery methods for cellphones, car manufactures also want to show off their tech and prove it is better than others.

Tesla has offered access to their charging network (as they have done with their patents) to other manufacturers, but everyone else wanted to do it their own way. In Europe, the Unified CCS standard is will on its way to becoming universal. Even Tesla have adapted their Euro-spec models to use it.

danwat1234, he probably meant 80A not 90 kW. The Tesla HPWC in US has 80 A max, 19.2 kW.

Yeap and why i love pissing them off

True, but the chargers need to be self-sustaining so that the network can continue to expand. It can't be a cost center forever.

Lol and people think he a saint he just a scrooge mcduck at heart

Whether L1 charging is easier on the battery is debatable, since a battery recharged using L1 will spend a larger portion of its time at higher states of charge, and high charge state is held to be one of the major stress factors for battery longevity (along with temperature). Also, at least some cars (my LEAF, for one) impose a fixed overhead power drain during any charging (brainlessly running a cooling pump regardless of whether things are actually hot) operation, so L1 charging is less efficient than L2.

@@levenkay4468 what do you mean by "higher state of charge"? Level 1=12 amps, Level 2=30 amps. You have a battery cooling pump on your leaf? Mine doesn't, nor has any leaf ever made. No active cooling has long been the biggest criticism of the leaf.

@@levenkay4468 if by state of charge you are referring to the potential damage to batteries caused by leaving your car sitting with a full charge, you can mitigate the risk with smart use of the charge timer, regardless of the charging level.

@@1964mcqueen No, of course there's no cooling pump for the _battery_ ; that would be too sensible. The LEAF *does* have a cooling pump for the onboard charger and possibly the power inverter for the motor drive, though. And that pump runs whenever the car's charging.

@@1964mcqueen Yes. But the faster the charge rate, the more the car can postpone the actual charge operation, thereby sitting for a longer time at a lower state of charge. If all you can do is L1 charging, the car probably has to start charging as soon as it's plugged in, meaning that it will inevitably sit at higher states of charge for a longer time as it slooowly approaches full charge. Admittedly, this is splitting hairs, but you did say that L1 charging is less stressful, and I'm offering the "how long does the car sit at high state-of-charge?" argument in opposition.

It's really not. The J1772 / CCS is becoming the standard. With the J1772 / CCS configuration you can charge on Level 1 , level 2 and Level 3 ( DC Fast if equipped in the car). He mentioned CHADEMO as the oddball, and while there are EVs with CHADEMO only ( level 3 DC fast ) most manufacturers are favouring the J1772 / CCS setup, especially in the U.S. Think gas station nozzle. They are all the same (J1772) but flow rates may vary. Think of CHADEMO as the diesel nozzle at the same pump that's on the way out. The Apple in the room is Tesla. Fun fact though....all Tesla model 3s delivered in Europe are equipped with the J1772 / CCS configuration. Electricity is the same, but plugs can be changed.

Hydrogen is electric. Hydrogen Fuel Cell vehicles are pure electric while also sporting a smaller battery.
