[ Ben ], Alright, so my friend Dan and I tried to do these things where we had a gas can for a Tesla.
We tried with this little battery that he had from Anker and it wasn't grounded.
I'm gon na stick this in here.
( grunts ).
It's going in.
, Oh no, Charging, cable fault.
, So it didn't work at all.
Then he got a much bigger battery and had an electrician friend rig up a thing that kind of tricked it to think it was grounded.
And that worked but not really. 00:00:25
How many miles did that $ 1800 battery pack get me Ta-dah 196.
We gained a whopping two miles extra range off of a battery pack that took me all night to charge.
What have I learned off of this? First, I would say I don't recommend you buying a giant battery so that you can use it as a gas can for your car. 00:00:47
Does it work Technically yes.
? Is it something that's usable, Probably not.
? So I hit up my friend Jehu who's kind of a battery DIY guru.
He's the one that made those DIY Powerwalls.
, And I asked him if we could do something. 00:01:02
So I'm going to meet him now and hoping that what he has come up with is something that will actually work in the case of an emergency where you need a couple extra miles of charge.
: Let's go.
( upbeat music, ), Alright, so I'm here at EV, West with my friend Jehu, who is the man when it comes to batteries - and he tells me that he's made something that might work as a gas can solution for a Tesla.
So Jehu? What do we got? Goin' on? We got a battery box So yeah.
It's essentially a battery box.
Here's the thing like to charge a Tesla, it's pretty pretty hard.
[ Ben ] Yeah.
, Like you know it requires a bunch of power.
, And so I think, there's been a couple of times that I haven't been able to went.
[ Ben ] Right we've failed multiple times.
Yeah, so the reason is because the battery wasn't big enough and because your inverter wasn't big enough right, And so even though there's a battery in the box and there's an inverter just Tesla is asking for it too.
Fast too hard.
[ Ben ], Mhm.
, And so the only way to do it is to do like a dedicated system.
, [ Ben ].
So each one of these, what kind of cells are these? Are these -- they each the same 18650s Or These are 18650s, so essentially the same cells that are found on your Model: S.
[, Ben ], Right.
, Not the Model 3.
The Model 3 has different, slightly bigger cells.
, [ Ben ] Right and how much energy do we have in here? So these are 3000 milliamp-hours.
, So there's like 196 of them, so that equals to 2.
2 kilowatt, hours.
[ Ben ].
Okay, let's see it.
Show me the money here.
, So here's what we'll have to do we'll have to plug this guy in. 00:02:38
Let me turn that off. 00:02:40
It's got a switch here.
And you'll wan na do that, because these inverters have large capacitors inside.
, And so, when you plug in like live, it will spark.
So you basically plug it in here.
, And even though this is set up for 110, it will handle 240 or 220 or whatever no problem.
So then we turn our little.
You know our little switch.
[ Man With Black Shoes ].
It didn't blow up Didn't blow: up.
[ Man In Blue Shirt; ], No fire.
; Okay, so we have power.
, [ Ben ], Okay.
DC/AC and then 29.
[ Ben ] DC okay.
So this is what's coming: in.
29 and then this is what this con -- uh inverter Inverter.
, [ Ben ] Inverter, is changing that DC to the AC.
[ Ben ].
Okay, cause that's what the car wants.
[ Ben ]! Unless you had a Supercharger which is .
, [ Ben ], Okay cool.
, So which car do you wan na try? First, We have all three cars here right.
It seems like the Model.
3 might be the easiest one to start: with.
Let's try it.
Let's try it.
(, Jehu laughs, ), Let's see.
, So you brought your Model 3 and which one is this: It's just the Standard, -- [ In Unison, ] Standard Range, Plus.
, Okay, cool.
, I'm a new Tesla owner.
So I actually don't know what I'm doing when it comes to Teslas.
[ Ben ] Moment of truth.
Drum roll please.
[ Jehu ] There we go.
, Then we wan na open up over here.
So you can see.
[ Ben ].
It's green ( applause, ), [ Ben ], It's charging, But it shows seven amps.
, That's good though.
! That means it's gon na work.
, So it worked.
It works yeah.
It actually is charging.
We pumped it up to ten amps.
And it said nine miles per hour that you would be getting.
Now how long --.
Now, if it actually sat for an hour, you think it would give you nine miles.
So I actually did the test and it came down to 333 watt-hours per every one miles of this.
The 333 is the inefficiencies of this thing.
I was gon na say so.
Is there any loss between Yes.
This guy, this guy to there? So I'm estimating it's about 70 %.
It's only getting 70 % of the -- 70 % of the battery life.
, SO 2.
2 kilowatt-hours Yeah.
Times 70 % Yeah.
, That's what you're getting in there and that's.
What's turning into ten miles.
, Okay, now [ Jehu ]! Let's try yours.
, Let's try a real Tesla.
So now we have, the gas can here.
, I'm just calling it a gas can for why Electric gas can.
, Oh the electric gas can.
, Also known as a battery.
, (, laughs, ) Michael.
This is your car.
, And so do you think Jehu's gas can is going to break it or not.
Well I'll say this much: it is a salvage title.
( all laugh ), So we're gon na start with that one and we'll go from there.
, But I have faith. 00:05:52
I think it's gon na work.
Okay moment of truth.
Here we go.
[ Jehu ], Let's plug it, in.
[ Ben ].
Oh Push: the button.
( voice slowed ), I'm a new Tesla owner.
[ Ben ], Just plug it in [, Jehu, ], Hey.
Let me run over here.
[ Ben ].
It's green, Oh charging stopped [, Jehu ], No [ Ben ] Nope! Oh, we broke it.
We broke it, [ Ben ], Maybe the amps are too high.
No, his amps was too high, so I turned it down to the minimum that allows you, which is five amps.
, [ Ben ], Five.
, And it's charging at five amps.
And it is confirmed on the console, there.
[ Ben ].
It said it was charging and then it just died.
Okay, ten amps.
, Now you're at seven amps.
[ Jehu ] Put eight amps.
[ Ben ], Eight [ Jehu ].
Can you click on the plus? Do nine.
[ Michael ]? Tell me if you got it.
[ Ben ] Yeah.
I got it.
[ Jehu ].
Can you do ten Something like that? Ten Ten amps [ Man In Blue Shirt, ] What ( beeps loudly )? Ah [ Ben ]? Oh ( voice, slowed ), I'm a new Tesla owner.
So, on the Model 3, it will do ten amps.
, But on my Model S it would only do nine amps.
[ Ben ] Mm.
Still, though I mean that's six miles per hour.
, So the idea is, if we're stuck somewhere we're, you know, literally died.
Whatever reason ignored the warnings about getting to the charger, Yes.
( all laugh ), You know we stupid Tesla owners.
We could get a mile in half an hour.
, A couple miles of range, probably Yeah.
Well, this will last more than an hour so.
No, but I'm just saying like look like oh man, I couldn't make it to the charger.
, It's a half mile away.
This is literally what happened to Dan.
( laughs ).
But you know this kind of a thing where I just need a couple of extra miles. 00:07:33
I don't want to wait an hour at that point.
I'll just call a tow truck.
This could give you that.
In the three and the S.
Just make sure we adjust the amps to not ten.
Yeah, the amps.
, ( Ben laughs, ) And, of course, that's just for this one little battery that I built right Right.
We could build a specific battery.
You could build a big .
Yeah, but this is the point is to try to use something like this. 00:07:52
Now, let's try the granddaddy here.
[ Ben ], We're doin' it Seven amps [ Jehu ], Seven amps.
How are you lookin' on your side? Wan na go ten [ Jehu ], Another amp.
Yeah, another amp.
[ Jehu ], Let's see where it quits.
Okauy we're at eight.
You want nine We're at nine, We goin' ten [ Jehu ].
We could do ten.
, Let's see if it shuts off.
, Maybe it won't shut, off.
, ( loud beep, ), ( Ben groans and laughs, ), (, upbeat, music, ).
So after testing it at EV West with the crew there and making sure that things were gon na work.
We brought it back to my house and we charged it up fully.
Now in order to charge fully, we had to have some specialized equipment, because inside of that tool, case was just the battery.
And after we were able to do that it charged.
For I don't know, maybe an hour or so.
It didn't take that long cause.
It was already about 60 % full when we started.
We dumped it all into the car.
Into my Model, X.
We had to use the version three of the UMC, the mobile connector, because the previous version that I had wasn't working for some reason. 00:09:22
I think the cables weren't able to handle that much voltage back then or whatever so it just didn't work. 00:09:27
So we had to use the new one.
And then we were only able to get about seven amps at a time which means that the rate of charge was relatively slow.
So we let it run all the way down for about an hour and we got four additional miles of range. 00:09:40
So what happened was as the battery drains? It loses its ability to push out as much voltage. 00:09:46
It essentially gets weaker, as it you know, has less energy in it.
And at some point the car system, the charger in the car just says: `` You're not giving me enough, and so I'm just gon na shut off''.
So it just kinda, says `` You're done here'' and stops charging.
, So there was still likely another mile or so of energy in the battery.
But it didn't have enough in it to push it at the rate that the Tesla wants. 00:10:07
So does it work as a gas can? Is this the solution to you know running out of energy when you're on the road trips, I don't think so. 00:10:19
Unfortunately, it has nothing really to do with this solution or any of the off-the-shelf ones.
Just Teslas are power, hungry beasts when it comes down to it.
The amount of energy that is in a car like my Model X, can power my home. 00:10:31
You know air conditioning, refrigerator lights, tv all that for two to three days.
, That's a lot of energy.
And so in order to actually fill up that battery or get it to.
You know a point where you could make it 20 miles or so to you.
Next, stop is just not really something that you can fit into a small compartment like that.
Now this solution is really cool and has many other use cases. 00:10:54
So if you want to check it out and learn how to do that, I'll put a link to Jehu's channel.
, I think it's fascinating the stuff he does, but in terms of a portable solution as a gas can don't really think this is gon na, be the Answer.
Or in fact I don't think there is going to be an answer.
, So the only other thing I could really think of would to be if Tesla enabled vehicle to vehicle charging.
Where imagine, if you're in your car and you can hit a button and kind of call a Tesla in there area and say, hey I'll, give you 25 bucks? If you come give me, you know 20 miles of range.
And that car would have a lot of energy in it, because that's you know how it's made and the charger there should be able to put out enough to give you.
I don't know 20 25 miles in an hour, maybe So other than that.
It's really hard to imagine a solution here.
That would help with this.
Now I know AAA they're having photos of something that AAA the tow truck service reported that they would do this.
But when I called them - and previously when I did my range tests on my cars, they had no idea what I was talking about said.
They don't have that they've never heard of it. 00:11:52
So I don't know if that photo wasn't real or you know, was just a pilot program or what.
So I think there's something that could be done here, but currently there's really not an option.
So let me know what you think.
, If you guys, are curious about this or you have any ideas.
Leave me a comment down.
Definitely go check out, Jehu's channel.
It's really interesting.
All the stuff he's doin'.
I'll put a link to that.
