Honda Clarity - Empty Tank and Dead Battery!

[@EdricLysharae]

Thanks for the small sacrifice to your battery to answer this question!

[@bobsykes]

Thank you so much for doing this so I don't have to. The Clarity is amazing.

[@steinervision7643]

I just bought a 2021 clariti, best car I have ever driven, including a tesla.

[@8ctopus0000]

This was cool! Now I know how my car will behave during the apocalypse 😁

[@CoreyJones314]

Thanks for posting this; I was curious about the behavior at empty. I haven't found any Honda literature on it.

[@nathant5741]

I've been curious about this myself; thanks for the video. Also, the engine doesn't physically engage to the wheels at low speed so your not going to get much power from the direct generator to motor electrical coupling. Engine just has a single ratio planetary gear to the wheels which engages the clutch only over 45mph from what I've read. Primary drivetrain is electric motor.

[@voodoo-rides]

Gas you put in won't register on gauge unless you have car "on" when your release the gas door. Don't understand why it does this but the gassing proceedure is spelled out in manual. I found this after doin same thing you did, I didn't understand why it didn't register. Looked in manual and also noticed after filling it correctely by manual after a couple on cycles went back to normal.

[@CBTalon97]

Interesting test so we know what happens. What you need to consider when you are driving on ONLY the gas engine is that the engine won't be powering the wheels at this point. The engine is only turning the smaller generator which in turn powers the drive motor. That's why the engine will rev up, but you won't see an awful lot of power.

[@NatiYolieX]

That is not entirely true. Depending on the speed, the gas motor will either directly drive the wheels itself, or connect to the shaft of the electric motor to make it a generator. See link: www.reddit.com/r/Clarity/comments/bmkn06/honda_ecvt/?

[@CBTalon97]

@@NatiYolieX I'm aware of how it works, but it doesn't couple at low speeds as shown in the video.

[@NatiYolieX]

2:45 If you wanna skip to what starts to happen as the battery runs out of its last little bit of charge.

[@wordcarr8750]

Actually interesting...but in the way of a joke: I've been driving for about 65 years, and now my Honda Clarity will likely be my last car. Thing is, after being engineer educated, I've never left any of my gasoline (only) cars run out of fuel...just assumed they'd stop running. So am assured in my thinking by your test. :>)

[@techontesla5284]

💀😰💀

[@htnowpro]

Wow. That was extreme testing.

[@marcelstanford430]

As I understand it the battery regularly uses only 12 kw-hr out of the 17 kw-hr total capacity of the battery. This is to avoid extreme full charge and empty charge swings and therefore help with battery longevity. Probably not a big deal doing it once but you're doing what the Honda engineers engineered the car not to do.

[@johnwang8799]

I have been noticing the same that is good for the battery, I have learned recently that we should run gas engine on once a week to keep the 12v battery charged otherwise the agm battery can be dead and uunable to start the engine

[@nathant5741]

@@johnwang8799 Not sure about this for the 12V battery. I've gone months on end without running the engine. I think the 12V battery is maintained by other means. Might not even be an alternator. (Granted I don't do this often, good to have the oil flow to keep any o-rings and other seals healthy.)

[@Jusumoner1]

@@johnwang8799 12v battery is charged by the high voltage batteries via a converter

[@johnwang8799]

Thanks a lot for the information, so I can leave the Clarity in garage for a month without trickle charging when I am on vacation? But somehow my engine turns on even when big battery is fully charged, I thought it is for charging 12v. Your reply will be greatly appreciated

[@Jusumoner1]

@@johnwang8799 Complicated system starts the engine to purge the extra electricity when the car is fully charged and you are breaking/regenerating. Basically the generator drives the gas engine nor the high voltage battery would be damaged if the car tries to regenerate a fully charged cell. So to answer your question yes and no because the car need to be started to activate the convertor for the 12v battery to charge.

[@youdoer]

What if you push the HV button? That may prevent the issue when you have no battery power. Love the video.

[@alljerseystudiosnj]

Well at least we learned that it would be truly hard to get stranded!

[@avecrux333]

I would never push limits like this with my battery in a PHEV. If I wouldn't let it happen in real life to avoid abusing the car, why risk battery damage just to experience what SHOULDN'T ever be allowed to happen?

[@FORZION]

He probably leased

[@prapapimthummong2878]

Thank you for your video.

[@alexgower7141]

Can you change brake pads at home without going to the dealer or a specialist.since I can't find a video on that subject.plz advise.thnx.

[@Prodigee514]

You're awesome thank you for this video!!

[@RyuMoto]

Awesome testing! Thanks for sharing

[@marchcyr1811]

Interesting that the dash board does not show drive mode, my 2021 does. All I can see id D then drive under it.

[@randomvideotosee]

how much "louder" is it really when the engine/gas does kick in? I hear the Volt is quieter, but the volt is also a compact car. The clarity look like an amazing medium size car like the Accord or Toyota Camry. But when it switches to gas mode, is it really "that loud" as some people claim or is it really just a sound of an engine turned on lol. I like that you can force the engine on the highway like the Volt's "hold mode" does

[@jonathancochran5134]

I have a clarity and the engine does seem loud more so at slower speeds than at highway speeds, but it might be more noticeable because it is so quiet in full electric mode.

[@franciscoortiz6980]

I guess you did this as an experiment ? Not sure why... if your gas gets below 30 %... stop and fill up. Why risk damaging battery? No batteries want to drop below about 20%

[@alljerseystudiosnj]

Well, did the engine restart after filling the tank?

[@randomvideotosee]

"battery dead" .. **car stills drives. I knew electricity wasn't real.

[@tomwebber5094]

I'm going to agree with several people here and say as a one off experiment this is probably not going to do much, if any, long-term damage to the system. These cars are certainly over-engineered, but I would not push it. My Clarity Plug-in has just turned over 28k in less than 2 full years and I'm actually enjoying it more vs less and plan to keep it when the lease expires in a year. New tires kicked my a$$ at $1,100, but they will go 70k and then I'll turn it in for something else.

[@techontesla5284]

If you were on the EV completely dead, you’ll probably get close to 60 mile range

[@theamazoner4075]

( Not trying to be a troll)This is risky the car uses the drive battery to start the engine if you leave it like this for more then a day the you might not be able to start the car even with the engine nice video though

[@VegasGuy1975]

Completely different battery used for starting and operating functions, than the one used for powering the vehicle.

[@александрзайцев-н7ж]

Как рыцарь дорог 😜🔥а как она едит на парах водорода? 🤔как мобила ноет когда сядет🤭

[@BigAl60504]

Good to see the car has a moron mode....this is terrible for your battery.

[@NatiYolieX]

I'll report back if this testing has any negative long term affects. So far my range is exactly the same as before the testing.

[@brandonott7258]

Yeah for a short period it dipped below then was started back up and brought back to hybrid range so I doubt it would have much of any damage. Now If it sat for a while that low, there would be more battery degradation for sure lol. Awesome test tho, I really enjoy seeing how something like this tolerates this as there’s always that chance that the gas motor can die from no gas or something else and it’s nice to know that the electric part is still propelling the car even tho the gas part has failed. Kinda wanna buy this car just from this test. Lol

[@teodyd7464]

What stupid person would actually this on his car?😂😂🥹🤣🤣🤣
