We need bi-directional charging from vehicle to vehicle, vehicle to house & vehicle to power any 110/240v device, anytime, anywhere.
Needed like an extra leg. 😂
Cyber truck already has it
i hope people consider the battery wear for bidirectional..
Yes thankfully the battery warranty on most cars is mileage and time based so even if you put excessive wear on the battery through v2l, it won't impact warranty claims.
Isn't the point of a battery to... use it?
@@Anon_0192 Yes but it will make the batteries not last as long. Batteries only have a certain number of charges and discharges. Once that number is hit. The battery can no longer charge to 100%.
The amount you will utilize this feature it won't be a problem. Even if you used the battery for a power source overnight it won't be an issue.
@@al73r hah I guess you haven't run a window AC unit 24/7 for a summer
I’m trying to figure out how the school bus idea is a good call.
Batteries are heavy. There’s no need to have a ton more on board battery than the vehicle needs. You’re better off buying batteries and leaving them connected at all times.
And if the bus uses the full charge and then needs to power the grid …. How does it take the kids home?
A few hours of charge between the morning and afternoon run doesn’t seem like a big deal. All of that is leading me back to the superiority of separate batteries in a county. The bus can’t REALLY do double duty.
Right Zero. Don’t try to make sense of this whacky idea. Logic has left the chat.
It's a terrible idea to use a school bus to power a home.
I think what their trying to get is the fact that large companies have large fleets sitting idle which has an enormous potential of stored energy. This energy could be used to bolster up a grid at times of peak demand or during brown outs or when renewable sources are underperforming.
@@wiseguy250505 I get that. Why would I want to add hundreds of pounds of battery (thousands of pounds?) to a bus I give the bus power it doesn’t need?
If the bus only has the standard power it would normally have … is that actually enough to offset? Ideally, wouldn’t each bus be nearly at 0% power every day or two? It isn’t like a car where you have wildly different needs from moment to moment. It drives a set route. ANY more battery you put in that bus is weight and cost the bus may not need.
Maybe each bus gets used for two days so only half the fleet is charged on any given day. Whatever the details work out to. I’ve put zero thought into this.
Point is, if those buses are normally carrying around a ton of waste batteries … what power WOULD they have to charge the grid?
I’m all for electric busses. City buses where I live have been electric for decades (power lines like a bumper car, not self contained batteries).
I’m also all for maintaining batteries to help the power grid.
I just don’t see how the two work well together. How much cost to we throw at this to help for … a dozen days per year? Extra weight. Extra cost. Extra maintenance costs. And now you have your precious backup power solution roaming around the city and susceptible to crashes and normal vehicle maintained requiring being put in a shop (which can potentially be mitigated by allowing buses in their shop to power the grid will being worked on or while sitting and not actively being worked on).
@zero11010 yeah all very good points.
There is a lot to be figured out going forward. We're still very much in the infancy of it all. We're not even 100% sure it will be batteries as we know them that we will settle on.
Wether it's battery, sold state battery, super capacitors, hydrogen or some other as yet discovered method electric is here to stay.
One thing is for sure the cars are responsible for a huge amount of night-time generation from the grid. So power plants have to ramp up production where they didn't before. So there should be a responsibility of those cars still plugged into the grid during the day to offset times of peak demand. Even if its only a tiny amount for very short periods collectively.
Like when the most popular TV shows go to advertising breaks there is a huge increase in demand as everyone gets up and puts the kettle on or the coffee machine, believe it or not its a recognised phenomenon in the grid industry. So instead of more coal being dumped into your power plant for those 5 mins the cars could offset. Just 1 example.
@@zero11010 the buses only run for about an hour in the morning and an hour in the afternoon. That leaves 22 hours for charging and discharging and still have plenty of power to take children to school and back.
In India only the Hyundai ioniq 5 and the KIA EV6 have bidirectional V2L systems, oh, I forgot, also the BYD atto 3 features V2L… do the Volvo XC40 recharge, and the Mercedes EQ-x series have bidirectional charging?. Not sure… excellent informative video, loved it…..
Nexon EV too
Great delivery, thanks for this.
The EV charger process is always evolving.
00:36 you guys suddenly switch camera in shot??😂 Got very bright quickly ☀️
Just one of the problems with auto focus, auto aperture, auto white balance cameras. Pros use to set up the camera for the shot and you wouldnt see things like that and other trash like auto focus trying to make up its minds. But now its -lazy- easy to just let the camera do it all.
W8ll there be a way to retro fit a current EV to make it bidirectional in the future or will we just have to buy a new EV?
ChaDeMo like on the Nissan leaves sold outside the US have been capable of car to house bidirectional charging for over 15 years now 😎
'leaves' lmao
@@nc3826 seemed correct lol
There's one HUGE drawback to using bi-directional charging not mentioned in this video. Every time you discharge your EV battery, you're wearing it down. Although battery tech has gotten much better, no matter what, every battery has a finite number of charge/discharge cycles. Ideally, your EV would have LFP (lithium, iron, phosphate) chemistry, which allows for a ton more charge/discharge cycles without degrading the battery.
Assuming your car DOESN'T have that kind of chemistry, I think the best solution would be to have fixed battery storage (like Tesla Power Walls), just not that many of them. So maybe 2 power walls, which would store about a day's worth of power (with conservative use) and in the case of a blackout, you'd use your car only if your fixed storage became depleted.
Wonder if we will end up with wireless bidirectional charging like wireless CarPlay
My greatest happiness is the gains I get consistently from my venture despite the business cycle. The U.S NFP is a key factor and knowing how to use it is really rewarding.
With this gains sent to my account each week, Gwen Irene Hodges is soo amazing
I believe for sure he is one of the best in this field and I've heard a lot about his success stories
I have heard a lot about ventures with Gwen Irene Hodges and how good he is and how he has helped people on ventures.
No Please Who is this Gwen Irene and how does he even trade , i'm interested in getting to know how it all works !!.
He is my family's personal Broker and also a personal Broker to many families in the United states, he is a licensed broker and a FINRA AGENT in the United States . My family got in touch with him after he did a broadcast on ABC NEWS about his profitable investments and trading , he is so awesome that my family is now debt free ...
DC Solar --> Hybrid Inverter --> DC Batteries --> DC EV Charger --> EV DC Battery.
DC EV Battery --> Hybrid Inverter --> DC Batteries.
No inverter loss from converting between AC & DC in the above to scenarios.
We need...Bi-Directional DC EV Chargers
...so that we can use as much of our solar PV generation without loss due to converting back and forth between AC and DC.
All this is going to do is make battery charge theft rampant
KSure beats getting gas in your mouth when stealing energy to power your car. Just park next to another car and plug in. No fuss , no mess. As easy as stealing a car with the key Fob nearby
You can’t get the car to discharge energy unless you have control of the vehicle. It’s not like siphoning gasoline. It’s not 1950. It’s 2024.
Wow you can plug one ev into the other ev so you can go the same distance as a regular vehicle
Wow another scared trolling luddite
It’s a regular vehicle? A polluting ice vehicle that cost more to maintain and operate?
Government regulators are getting in the way of car companies to make cars people want, and can afford.
0:38 Nice "EV" packaging, Kia. Lolol. No frunk in a dedicated EV platform. Amazingly lazy
This channel still shows cars? 😂😂😂 Oh how i wish CNET on Cars with Brian Cooley could make a return 🥹 Cause “Smart People” ruined this channel man.
EV losing money and going broke.
There's these things called portable generators, see? They use liquid fuels and are awesomely convenient - and they don't reduce range on your battery electric vehicle.
The energy conversion efficiency is pretty low though no? You’re wasting most of the liquid energy to heat energy and pretty little useful energy
@@chunks6856 - It converts more efficiently than wind or solar and has the added benefit of making a certain gas that is made from carbon and oxygen which feeds plants via photosynthesis! Win - win -win!
@@whitehorse1959Are you sponsored by oil refineries?
@@edwardhoffenheim3249Do you normally speak before knowing?
Yeah! We don’t wanna use those and this video is not about that. Cheers 🥂
ANY EV charging really sucks 🎉🎉🎉
So you say any EV charging sucks, so care to explain how you came to that conclusion?
he means Commiefonia 😀
