Absolutely great addition to the test suite. I am sure that each manufacturer has residual capacity to do two things: 1. Mask the hi volt batt degradation, 2. Protect the cells of the hi volt battery ( they don't like being completely depleted). That i4 M50 is very efficient as is the Ecoflow. Great vid!😁
@@dondonaldson1684 i know it, that's not what i asked, how can you take more energy from the battery without change the voltage limits? Like, if you have 10kWh between 350V and 400V how can you take more energy from it without change the lower or the upper voltage?
@@antoniofreitas6335 what Bjorn and I are pointing out is the following: manufacturers are saying the capacity is "x" when it is really "x" + 5-10 percent. They are masking the degradation of the battery's capacity over time. Bjorn showed this in his test. I hope this is more clear.
@@dondonaldson1684 is very far away from clear, manufaturers limit the capacity by limiting the voltage, all packs are full or empty when they achive a voltage point, if you understand something about electricity you know that the capacity is betweenthis 2 points of voltage, you can´t mask capacity without moving this points, like Tesla did before in emergency situations and free the upper part off the battery, Tesla did that by moving the upper voltage of the pack by software, that's the only way to do it..

It will be very interesting to see how much below zero can go older cars, f.e. leaf I or old Zoe . It can be part of degradation test, very useful for second hand buyers
Thanks, its an interest test. Of course another factor is it might have 20km left in it at 0% but when its a few years old it may not. Nothing like a Japanese eco ICE car though which typically have 50 - 75km left once the fuel gauge gets to empty - not the same situation for at least a couple of American ICE cars I have driven where empty often means empty (I have twice coasted into a fuel station in neutral in the USA with the engine stopped!) - who would of thought ;-)
This is very useful Björn and especially for EV drivers. Great video. 👍. Matt Watson on CarWow in the UK did a similar videos testing quite a few cars until they died. Very interesting how many cars actually went beyond the zero and by quite a lot of margin as well. Not sure in Norway if they have similar to the UK were many breakdown organisations now have on many of their vans electric generators to give customers enough power to get to the nearest chargers. But be good to add this to your tests as it will definitely help EV drivers what to expect if they breakdown. Sh*******t now you have test every car again 🤣🤣🤦🏻♂️
Very interesting test. I would be afraid, that it would not allow you to start again until you get over 0% displayed. And that power station does not have big enough capacity to do that. 21:40 You can buy generator for 20% of the price of that Honda with 3kW+ output. Not sure why Honda is so overpriced (I suspect there is a reason, but even good brands are much cheaper than that). That said, Ecoflow is also overpriced, so I suppose it's "fair" to compare those two.
@@geon2k2 Many do. Not the cheapest ones, but even if you pick those that cost half the price of Honda, you will most likely see pure sine wave. There are many good ones like Gude isg 3200 - half the price, 50% higher power, inverter or Scheppach SG 2500i -same power, price one third or less, inverter.
This test will be so much more dependant on temperature, and previous charging cycle.. the battery voltage on low SoC and the cell voltage difference is not really important for normal driving, but at low SoC this becomes very dominant. Cold battery could easily mean the difference of having 15km left on 0% or stalling at 2%.
Great video Bjorn! This is a nice addition to the list of tests you do. Very entertaining! I haven't seen you run out of juice in one of your videos in a long time except for the race with Pawl, he would have loved to have that backup battery!
Thankyou for this - reassuring that in the event of a charger being unavailable that a car will keep going for a little while. This test would be good with a product like zipcharge (I assume other products are also in development) which has specific functionality for EVs (native type 2 support).
15:47 I think you also have to open the bonnet to show people that the car has broken down as I remember breaking down and occasionally people would honk and shout "you can't park there" when you are clearly broken down.

Great test :) Thank you, Bee Emmm Veee , for allowing Bjorn to do this kind of testing . We consumers want to know what happens when we are in an emergency low SOC situation :)
I have a Honda generator with ~1,8kW. Problem: the UMC of my M3 does not like it and refuses to charge the car. Guess the UMC does some checks for ground that don't pass.
@@CraftyStorm That could be a reason as well. I tried also with a 3phase 8kW generator but no luck either. Don't have an oscilloscope to analyze. On the other hand is that generator for longer outages for the house only.
11:45 Going up a hill with no power left is really scary. This part of the video gave me bad memories on a eNiro with around 5 %. When the hill demands more than turtle mode delivers, your are DON. No way to recover from that, even if the battery is not DED yet.
I dont know if something like ecoflow could be made with super capacitors and maybe then charge the car at 150 or 200kw so people dont wait long to get the charge, that would limit it only to charge cars maybe but for some people it might be a lifesaver if such a thing is possible.
Super capacitors have such a small capacity compared to normal batteries so I very much doubt that it would be feasible, but would be great for that quick emergency top up
You got your fair bit of warnings ! There is no reason to have an acoustic warning, it is annoying. OK the acoustic alarm is subjective. However to drive the car down to it stops, is a good idea to inclement in your test. It was the first thing I did when I got my i3
Since driving until complete shutdown will most likely never happen for people... a audible warning would be good so you actually know for sure when it's done.
@@huzygaming7216 Well, you will feel tha it isn't able to acc. and it becomes worse and worse, so if you drive completely to death stop, you are reminded by the lack of acc.
I tried a Honda Eu20i on my Model S. It could do 8A = 1.84kW continuesly giving 10km range per hour of charging. You could parallel 2 units to double that. Note that most gens do not have a neutral earth link which your car or chargeadapter may need to see to function. I made a special cable with such a link. Wish you had run it until it stops.
@@Simon-dm8zv In many counties the Neutral conductor is not free floating but linked to Earth inside the switch board. A generator does not have that link, both Neutral and Phase are free floating.l made an extension cord which has a circuit breaker and that link.
@@moestrei Yes, and my question is which two things this extension cord connects. Does it lead from the generator to the earth (in the most literal way, as in soil)?
@@Simon-dm8zv No, the earth stake is a separate issue. The extension cord has three conductors (in my county): Earth = Yellow/Green, Active = Brown and Neutral = Blue. I have a box in the middle of a 15 Ampere extension cord which contains a 16A circuit breaker and a connection of the Neutral wire with the Earth wire. In other words: My box is a mini switch board. A generator typically has two floating outputs with 230VAC between them. My cable ties one output to Earth making it a Neutral and thus making the other one to an Active. Which one becomes Neutral or Active doesn't matter. The circuit breaker will trip in case the generator does have a link already and the cable tries to link the Generator Active to Earth. The Earth stake then connects the Earth conductor to the actual Earth. Some EV (Renault Zoe) are known to be sensitive to proper Earthing and will need that Earth stake but my car (Model S) did not require it.
Not at problem at all to have the charge port on left side. I just needed a few seconds to plug in. From there, I can watch the EcoFlow from the right side. No need to stand by the charge port... lol
Wow, that is very courageous of you. What a funny way of the technology evolution: you have to convert low voltage DC source to mid-voltage AC in order to feed the car with high voltage DC, losing twice on DC->AC->DC conversion. And that is only because the car is not designed to receive DC below 500v and has no dedicated DC->DC 🙈
@@mattg432 well, sure, it doesn't. But even if it had, it wouldn't help: ecoflow internal voltage is 48v, max output is 220-240v, while ccs dc voltage cut-off is 250v. The only way to boost 48v to 500v is this weird 2 step 48->220->500v (in fact even 3, car does 2 conversions when is fed by 1 phase current)
Nope. Did you notice that I plugged in within 2 seconds and that the cable is long enough so that the EcoFlow can be on the right side. I didn't have to stand near the charge plug at all...
Very Interesting! Perhaps you can try it on an old Kia Soul with degraded Battery? I wonder if the BMS eventually miscalculates on a used battery, so that the car shut down before 0% ? That would be also very interesting.
Now we're cooking. Nice one👍. Depends a lot of the Battery degradation. You could do this Test beside the new-ish Testcars, also with older cars, Teslas, Leafs, E-Golfs etc. Maby in combination with an Aviloo diagnosis upfront, so we can see at what degradationlevel of the battery, how much the car is getting under 0.
BTW, at least in the i3 BMW had some very clever way to recover a car from “near-death” - they would use the pilot signal of the Type2 charger to power up the charging electronics in the car! Then the car’s charger can signal to the charging station to start charging, and when it starts to pull power, a DC-DC converter will start to charge the 12V battery from the main battery. Basically, you can still charge an i3 with fully depleted both main and 12V battery. That’s one of the most smart things I’ve seen! I really have the highest respect for the i3 engineering team!
It's working slightly different. If the 12 V battery (as well as main battery) is totally empty, there is a dedicated small AC/DC converter to charge up the 12V battery once any AC cable is plugged into the charging port (but without car giving any sign of life). Power is drawn from the AC line, not the pilot signal. So its like a regular external 12 V battery charger, just built into the car and connected to the charge port. Once the 12V battery has sufficient voltage, the car computers will boot up, and allow regular charging of the main battery through the same AC cable. You can find all the details in the BMW University material for the i3. The DC/DC converter will charge the 12 V battery from the main battery under all normal circumstances, also if no charge cable is connected. (And I agree on the praise of the i3 team)
@@Orbit353 Correct, I oversimplified it a bit and was doing it from the top of my head. The smartest thing is: there’s no power on Type2 AC until you have signaled something like “car is ready to charge” back to the charger. But if all your circuitry is dead, who is going to signal? That’s where they pulled the power from the pilot signal, to actually initiate the power release from the charger - and from there on all the things are more or less normal.
24c is hot???? Here in Toronto it's normally 27-33c and humid during the summer. 24c is perfect!! You are a great actor.... I felt much stress for you.
Not a problem at all to have it on the left side. If you noticed, I only needed a few seconds to plug in. And remember that the EcoFlow can be placed on the right side of the car. Also remember that you have to pass parked cars, people, bicycles, etc with 1.5 meter margin in Norway.
By that logic the driver should have to slide over to the passenger side to exit the car, because opening the door for the driver to exit would take a lot longer don't you think?
@@allisterbullock213 the problem is not only plugging, but the actual plug sticking out of the car. The same reason you fold your mirrors so ppl don't crash them. And i have a feeling replacing the charge port on the car is more expensive than a mirror
In Norway you have to keep 1.5 m clearance when passing pedestrians, bicycles, etc. The same applies here. No problem at all. People just try to make up excuses for the charge port on the right side which is the wrong side.
Folding mirrors don't suddenly disappear altogether, I don't see a problem, even here in Germany without the Norwegian 1,5m clearance as Bjørn has already mentioned. Here people anyway tend to avoid the possibility of a car door opening although it seems not to be strict as in Norway.
I was going to try this on our Leaf on an EF Delta (sadly, no app for this version), but the US version doesn't have a ground pin so the EVSE (Level 1 - 120V) won't activate. Any way around this? The EU version Bjørn has appears to have ground pins. I suppose I just need to bond the ground pin to the neutral somehow.
This will definately be an interesting addition to the range tests
absolutely agree, great idea!
Top Bjørn, glad you are doing this test, so that we don't have to do it 😎
I have seen videos of Tesla's being charged and run by the Delta Max. This is the first time I have ever seen it used on a BMW i4.
One reason I like that power station is that it has more than 2000Wh of capacity.

That’s one of the most smart things I’ve seen! I really have the highest respect for the i3 engineering team!
It's working slightly different. If the 12 V battery (as well as main battery) is totally empty, there is a dedicated small AC/DC converter to charge up the 12V battery once any AC cable is plugged into the charging port (but without car giving any sign of life). Power is drawn from the AC line, not the pilot signal. So its like a regular external 12 V battery charger, just built into the car and connected to the charge port. Once the 12V battery has sufficient voltage, the car computers will boot up, and allow regular charging of the main battery through the same AC cable. You can find all the details in the BMW University material for the i3.
The DC/DC converter will charge the 12 V battery from the main battery under all normal circumstances, also if no charge cable is connected. (And I agree on the praise of the i3 team)
@@Orbit353 Correct, I oversimplified it a bit and was doing it from the top of my head. The smartest thing is: there’s no power on Type2 AC until you have signaled something like “car is ready to charge” back to the charger. But if all your circuitry is dead, who is going to signal? That’s where they pulled the power from the pilot signal, to actually initiate the power release from the charger - and from there on all the things are more or less normal.
24c is hot???? Here in Toronto it's normally 27-33c and humid during the summer. 24c is perfect!!
You are a great actor.... I felt much stress for you.
The joke went straight above your head...
@@bjornnyland I thought you were serious. LOL.
Dont be a zero hero.
Bjorn 2022.
PS love your vids dude
Hej Bjørn, can you also do some more testing with the bmw ix3? :)
Love this test! Also for old cars!
Perfect test as always! How many kilometers would a Tesla MY LR go under 0%/0km? What would you estimate?
Going back to the left or right placement of the charging port... In this case is a lot better on the right
Not a problem at all to have it on the left side. If you noticed, I only needed a few seconds to plug in. And remember that the EcoFlow can be placed on the right side of the car. Also remember that you have to pass parked cars, people, bicycles, etc with 1.5 meter margin in Norway.
By that logic the driver should have to slide over to the passenger side to exit the car, because opening the door for the driver to exit would take a lot longer don't you think?
@@allisterbullock213 the problem is not only plugging, but the actual plug sticking out of the car. The same reason you fold your mirrors so ppl don't crash them. And i have a feeling replacing the charge port on the car is more expensive than a mirror
In Norway you have to keep 1.5 m clearance when passing pedestrians, bicycles, etc. The same applies here. No problem at all. People just try to make up excuses for the charge port on the right side which is the wrong side.
Folding mirrors don't suddenly disappear altogether, I don't see a problem, even here in Germany without the Norwegian 1,5m clearance as Bjørn has already mentioned. Here people anyway tend to avoid the possibility of a car door opening although it seems not to be strict as in Norway.
I was going to try this on our Leaf on an EF Delta (sadly, no app for this version), but the US version doesn't have a ground pin so the EVSE (Level 1 - 120V) won't activate. Any way around this? The EU version Bjørn has appears to have ground pins. I suppose I just need to bond the ground pin to the neutral somehow.
Great idea for a series
Now I was eating when you said "it's running on only fans"...
Almost choked on the burst of laughter...
Great content! More videos like this please
Very interesting test to see how a car acts when the battery is extreamly low.
Bjørn, I was actually expecting Pavel to appear with a tow truck :) We haven’t seen him for a while already ;)
As always, very entertaining and informative. Love your vids. And “Now I need to take click bait photo” LOL.
