I Find Out How Far A Tesla-Powered Jaguar Can Go

[@scunnerdarkly4929]

Car powered by electricity. Driver powered by optimism.

[@SenselessUsername]

I think the main mistake was not organising a cheering crowd at the last few uphills. Ask any runner, it's that what gives them the energy to push through when their energy is exhausted... (Especially the very end, I practically heard the roaring crowd when he made it (kindof)).

[@KaminKevCrew]

I was 100% waiting for the contactors to open while you were in the super tight section of your driveway.

[@SuperfastMatt]

Fortunately that is angled downhill slightly. Though it would have made for great KZbin if I got stuck and had to yell at my neighbors to get a push.

[@ronconnelly]

I totally thought that was gonna happen. I have a similar LA driveway my 68 Ford F-250 barely fits down too. Those are times I’m glad it’s IC powered.

[@uliwehner]

@@ronconnelly why would that make a difference in this particular test scenario? If you put a say 2 gallons in your f250, roughly 10% of "charge" and drove it for the same distance, how many times do you think turning it off for a few minutes after it stalled it would have started again?

[@mcrsit]

@@uliwehner on manuals, if you put it in first and turn the engine starter on, the car moves under electric power. Not really useful for anything exept maybe an uphill driveway?

[@jameswyatt1304]

@@mcrsit just like when you can pop the clutch while rolling if there's enough juice to get spark, but not run the starter. When the engine runs, the alternator folds the battery back up. Seems to work better for carburetor cars, but fuel injection ones seem to need a lot more stable electric to start.

[@jonathangehman4005]

The funniest part was when you said "I should've gotten the bigger battery", as if you wouldn't have just gone a little out of your way or driven harder or left with less charge or any of a number of other "eh, so what" choices because you knew you had the big ol' battery. In the same way putting the bigger 35gallon optional fuel tank in your 78 Dodge D150 w the 440 doesn't prevent you from running out of gas on your way to high school marching band practice when you only put $5 of regular in at a time

[@12x2richter]

Agreed, when he said that I was like "No, really you just needed to charge another 5 minutes and you'd be good, and you know that now"

[@flightgamer7849]

So very true. I didn't buy his comment either. Still funny tho.

[@olegil2]

Not to mention the bigger battery wouldn't have charged any faster, so he would have still left the house with the same actual range in the batteries.

[@funkgremlin2765]

Well having a bigger battery would just be nice in general

[@michaelaguilar9751]

A long time ago when I was a teenager, I bought just enough gas to fill the carborator (yes, I'm old). It was just enough to get me to the top of the hill, roll down, and get into the driveway. This reminded me of that.

[@danwebber9494]

I was getting flashbacks too, the questionable decisions of youth!

[@doowlEnotniM]

Back when gas was an outrageous. .89 a gallon I bought enough to get home with pennies out of my ashtray. I ran out in front of my house and coasted into the driveway. This reminds me of that.

[@kunalchabria1989]

I remember doing a 60km trip around my city outskirts and got towed by on random guy back into the city when the batt died, you'd think we put the bike to charge as we got home, nah, we saw regenerative braking charged it up a bit so we went 3kms roaming in the city again. Barely made it home. Good times.

[@alexsalazar5161]

gas station?

[@mr_voron]

Oh man the sweaty palms while trying to get to that hilltop… My old BMW i3 often gave me this anxiety. 15mi of battery and home is 25mi away. Then by the time I got to the bottom of the hill range was 30mi. I swear they hired the Windows file transfer progress bar guy for range estimation.

[@nick4506]

i took a test drive of a fiat 500e and they had to cut the around the block drive short because the range estimation went from 30 to 1 after accelerating pulling out of the dealership. i think those California fleet mileage circumvention electric cars are pretty bad.

[@ShainAndrews]

Just a warning. You can be charged with theft of services. Don't ask how I know that, and I won't ask how you know to look for outlets on light poles.

[@TravisFabel]

@@ShainAndrews You can be charged with theft of service, but if you're willing to pay way more than electricity costs, you can also pay a lawyer to pretty much get off of any charges. It's an electrifying experience.

[@SweetLou0523]

@@ShainAndrews should be a pretty easy defense. If there is no signage prohibiting use, and the receptacles are not secured in any way, then they cannot charge you with stealing anything.

[@ShainAndrews]

@@SweetLou0523 Lets say you have a ride. I jump in it and take off with it. You claim I stole it. I claim there was no sign prohibiting use. You didn't lock it or secure it in any way...

[@SweetLou0523]

@@ShainAndrews not a great example though as most insurance companies would find me at least 50% at fault for that as I left it in a public place, unsecured, with the keys in it. In order for you to be totally at fault, I'd have to have locked it up and taken the keys with me. This would render it secured and obviously not for public use. Again, if the outlet is easily accessible in a public place like a parking lot, and has no security cover with locking mechanism, then they cannot charge you for theft of services. Especially since they don't have posted rates detailing the pricing on said services either. Imagine this: a water hose at a gas station. The spigot is not locked, there is no sign specifying payment for use. You fill up a water jug and go to leave, the clerk runs out and demands payment. When you refuse, they call the cops. The cops cannot do anything because the hose was readily accessible by the public, not secured, and had no signage posted requiring payment for use. Legally, you deprived the station of no goods or services. Literally the only action that could be taken is a writ of no trespass.

[@TheThunderwars]

It is always surprising but the first 10% of your battery is often worth much more range than the last 10%. So getting out with 93% might have been your mistake :)

[@SteinGauslaaStrindhaug]

Yes. Even if was measured entirely linear (which it's probably not); the first 10% from 100% to 90% are capacity you can freely use; the last 10% from 10% to 0% are percent that the system might not allow you to use. If the battery had just stopped charging when you unplug it and drive, the battery is already at the perfect temperature; this is particularly important in cold climates where the range decreases a lot if you have to start with a cold battery; so the estimated range will be a lot further even with the same charge because very little energy is needed to keep the battery warm enough. Also my 1st gen BMW i3 seems to continue charging a bit after it displays 100%; I can tell because the estimated range keeps increasing for a while even though the bar is full. I think it counts 90% of maximum charge as 100% (and probably 15% as 0%) to prevent us from wasting time and power reaching a charge level that it might never reach and might be harmful for the battery anyway.

[@TheThunderwars]

@@SteinGauslaaStrindhaug I'd say that it is due to cell balancing. Once you are "100%", some cells might be a bit above 4.2v or a bit below. It is important that each cell provides the same voltage so that they are not stressed differently when in use. It makes the pack less prone to sagging, which is why when you accelerate you can see a huge voltage drop, and makes the battery cells healthier for longer.

[@brucemcclary3260]

This doesn’t really seem like a glowing endorsement for this new technology,does it?

[@shaynegadsden]

Not really battery voltage decreases as they discharge so since you need a certain amount of power to meet what the speed controller is asking for then current increases, and as current increases batteries discharge faster

You need to wire up the brake pedel with a tilt sensor, so tippy-toe breaking uses 100% regen, while heel-braking uses 100% brakepads. If you had this you'd probably make it home no problems.

[@Chris-oj7ro]

Dang I'd never heard of this idea. Seems genius!

[@samuelalexander8030]

My buddy's Tesla uses only regen braking until you press the brake to a certain point, or at least that's what he told me. So you just have to modulate how much braking you're doing and you'll only use regen.

[@honthirty_]

@@samuelalexander8030 Cool story bro!

[@12x2richter]

@@samuelalexander8030 Typically, just taking your foot off the accelerator in a Tesla engages the regen braking, and then you use brake pedal if you actually need to fully stop (or panic stop). The Tesla brake assembly, master cylinder is the same as the one in the Honda CR-V, so I doubt it's doing anything fancy with part pedal application, unless it's literally just using the brake light switch to tell the motor controller to go into regen.

[@ashleyhamman]

Alternatively build in a "fun" and "range" mode. "Fun" means no throttle is full-on coasting, "range" means no throttle is regen, and he could set how much regen he feels comfortable with. I remember some hybrid a few years ago coming out with a hand-dial to turn up or down regen.

A previous comment suggested a generator; that would make it a hybrid, like a Prius! Perhaps not then.

[@Vaterkrater]

Love the channel! Wouldn't you agree "battery percentage" is of little use? I like the thinking behind the "cycle analyst" (ebike display from Grin Tech.). It's made for DIY´ers and displays the voltage of the battery pack and the watt hours used. When you get to know your battery, it's voltage and capacity at full charge, the low voltage cutoff etc., it becomes sort of intuitive how much range you can expect in different terrain, assist setting, weather, temperature etc.

For sure. I was so worried about range anxiety that my first foray into electrics was a Chevy Volt, which only has about 50 mile range, but then a fully capable gas engine behind it that kicks on when the batteries get low. It turned out in the 2 years I had it, we only had the motor kick on about 3 times. 50 miles was longer than you'd think it was, even when there's no risk of being stranded. Now the EV I built, which may have the same 40-50 mile range, but I've never had below 80% charge because I'm worried about how long it'll last.

"I should've gone with the bigger battery" - The EVers lament

[@gizzyguzzi]

Probably should have charged it fully before he left

[@12x2richter]

In fairness, the biggest reason for this is that the battery is THE most expensive part of the drive system. When you're trying something new, it's hard to go "Sure, I'll spend $24,000 for a used Model S battery pack and get that 250 miles of range". Matt went BIG here. I converted a 1955 GMC truck, and the EV equipment ran me roughly $10k. If I wanted a 200 mile range, I'd LITERALLY be adding another $18k to that figure, easy. That's tough to do when you don't even know how it'll drive, whether you'll want to be in it for 10 minutes let alone 3 hours!

[@e-grandpa9778]

I’m working on an electric car using 18650s similar to the Tesla Model S. I’ve built a motorcycle, snowmobile and ATV using these same cells. I put in an “Anti Range-Anxiety Switch” that gives me the option when my BMS kicks out the power to get home. The BMS shuts off at approximately 3.0 Volts per cell. At full battery charge I know my range and amp hour usage. I know this quite accurately because I test to BMS shut off. I then use the switch to get me home. Never draining the cells below 2.7-2.8 volts. The batteries will last my lifetime 😊. I’m also implementing the switch on my car.

The range anxiety is REAL!!! Even with my Chevy Volt, I get range anxiety, I can't imagine the stress of being mere blocks away from home without a charge. 😂

[@simonlang2001]

I get range anexiety all the time and I drive a gas car

[@EmyrDerfel]

I had range anxiety when I drove a Peugeot 306 turbo diesel and didn't have enough remaining overdraft to cover both food and enough fuel to commute at speed in the week before payday.

5:48 This car weirdly reminds me of the 1982 4-door Mercury Lynx I grew up getting shuttled around in.

That poor poor battery

[@isavedtheuniverse]

Simultaneously defeated but triumphant and yet still hopeful. What an emotional ride that was. You looked wiped out man. But uhhh...thanks?

[@leonardhaskins8892]

Perhaps we could start a crowd fund for a 'Mr. Fusion' reactor you could mount on the trunk of your Jag. Just imagine, a few banana peels and some empty beer cans and you would have unlimited power. Love your posts, am very happy whenever I see a new one. Thank you!!!

[@dawsonmoore7]

The contactor issue is likely a BMS over discharge fault. Pulling current through some resistance will drop the pack voltage. At some point during the drive, it’ll get too low and the BMS will open the contactors to prevent damage due to over discharge. When you let it sit for a few seconds, the power draw is gone, and the pack voltage will rise again, allowing the close of the contactors. Pretty cool to see it in action since Tesla hides it behind a wall of software protection

Just imagine if you had of started with 100%……All hail

You should try a battery pack with a power inverter, it could be your version of a fuel can. Hell, if it works you can cut up a Jerry can and make it an official emergency "fuel can"

[@djordjeblaga7815]

Apparently Li-Ion has around 400Wh/L of power density. My Bosch Powerpack 400 has 400Wh and is about the size of a Water Bottle, so that fits. 20L Jerry can -> Theroretical 8kWh of energy storage. Even if you cut that in half for good measure that's nothing to sneeze at.

a 1 KW 110v battery generator. can charge a T for ~ 4 miles.

[@salloroc20]

Woah wasn't expecting a video today! Thanks Matt!

[@davesmith9325]

That 7%=zero in the post script is an important learnings for everyone with an EV I think. Normally we would assume if anything there is a slight reserve behind advertised capacity, being short changed by that much could really embarrass people. In some ways knowing exactky how much you have is more important than having bigger batteries BUT my understanding is that lithium (and many other) batteries degrade exponentially more the deeper you discharge them, literally draining the last electrons like this really bad battery care. The moral is to plan journeys so you should never go below 20% ?

[@dittilio]

Can't believe how engaging this was... Unrelated, I'd love to have that car in my shop for a few weeks and fit out the interior. What a gorgeous machine.

[@Miata822]

People on Reddit have opinions? Who knew?

[@Daweim0]

Dare I say more options than people on KZbin

[@gin3648]

I don't think my nerves could handle an electric car, I have driven a car for years without an alternator but this is something else.

[@phenomanII]

Watching this while battling the low battery indicator on my wireless mouse made it an even more nerve-racking experience. Sure, I could put a new one in there (perhaps even the correct size), but I prefer the lighter weight and who's to say 1.2 something volts isn't plenty on a AAA?

[@jeffreyhough6720]

I'm at 4% battery on my phone when I finished watching this, I feel ya.

[@RustyCraftKnife]

Why do you need to move your mouse during a video?

[@phenomanII]

@@RustyCraftKnife The thing kept flashing red for 30s after every action. That is supposed to be the low charge indicator, but the battery voltage was above that treshold, so I kept messing with it to make it read the voltage correctly.

[@thebondini]

Love you narration and especially your dry humor.

[@leoncolyer9420]

Just carry a portable generator with you 😁😁 mount it under the hood and run the exhaust out under the back ! At least you can get some power back into your main power system

[@Sithhy]

A vintage hybrid Jaaag would definitely be a sight to behold

[@BenjaminT.Minkler]

the problem with that is, you would always be carrying around something you never actually want to use .....I realize that living out west USA(when I did) that it is pretty common to spend ~3hrs of each day behind the wheel driving; but where I live(now) I'd be visiting a whole nother state if I drove that far - and say if you lived in Europe you might end up in another country or something ... and it seems anywhere you go now in modern times, at least has power already there for light bulbs or something; but an old rusty leaking fuel can, maybe not so much

[@grahammakesstuff.1916]

If you're in a pinch, try drafting behind a lorry (UK), truck (US). I manage to use just over 30 miles of range on my 50 mile commute in my ID3. Obviously a completely different car, but same principle. All hail the algorithm. 🤟
