11:01 Conclusion
We need a 2023 update on this! :)
Please make a video going more in-depth about other aspects of your last e-bike like construction and wiring. You promised ;)
Great video, as always
Inzwischen hat man sich an dein Englisch gewöhnt, aber man muss auch dazu sagen, dass dein Englisch um einiges besser klingt als am Anfang :-)
2:56 "It's a little more complicated than that. But it's still very easy" .... says with a German English accent.
I use an MPT-7210 boost converter and a USB-C to 5.5x2.1 adapter and a 90w USB-C brick and it charges fine. I have a whole video on it if you want to click my name. The USB dongle was only like $17 bucks or something and the boost converter was like $30. I had a 90w USB brick and was charging a 48v battery around 1.25amps with it pulling about 81w so as not to totally kill it. With a 100w brick you could probably get 1.5amp or maybe more for charging. Considering most ebike companies cheap out anyway and give you only a 2 amp charger. You're not losing that much since at 2 amps that's around 109w at 54.6v terminal voltage. So theoretically you could get maybe 1.75-1.8ish with just using a 100w usb brick.
Well, now comes the fun part, you might be able use Powerbanks as range extender.
LOL thanks for the video! Since I'm going to take my eBike with me in my new campervan, I recently asked myself whether it's possible to use USB-C for everything instead of 12v and USB-A ports, in my van. 👍🏻
unfortunately although it's possible, it's just really inefficient at the moment, here's why:
firstly PD only supports 100w of power max, fast for the average consumer however I personally charge at 200w, secondly, pd does not support current limiting meaning you need to add a boost converter on the output of the 20v (which isn't very efficient)
Geil, neues video!!!
What! New video! Amazing!
Thank you for posting. Your enthusiasm for this stuff is changing the world in many ways.
Please update this now that we have 140w USB C chargers, and now Framework sells a 180w USB C charger. Framework is a reputable laptop maker so you should actually get what they promise.
What about parallel charging with two USB-C adapters? That would work and not be too crazy. There are light and powerful adapters (GaN based) that can easly output 60W and weight less than the one you're using.
You're finally back 🔥🙌🏼
Nice das du wieder da bist!! Ich würd mir echt wünschen dass du nochmal ein zusätzliches Video zu deinem E bike machst. (Details im Bauprozess etc.) Bau gerade mein zweites high Power e bike ebenfalls mit einem Kelly KLS. Würde mich interessieren ob du auch Probleme mit dem hattest. (Der erste lief 50km perfekt und ging dann gar nicht mehr (keine Spannung mehr auf den 5V Leitungen der zweite war dann ein Transportschaden)
ja die kellys sind n krampf das kann ich bestätigen. Musst schauen die halten teils nichmal so viel volt aus wie draufsteht. Zudem muss man die pids gut einstellen weil das ding das nich selber kann, was absolut komplex ist. Sonst gehn die sicher kaputt. Meiner geht noch super, war aber n brutaler aufwand einzustellen damit er jetzt gut geht.
Sabvoton oder die 300A Vescs würd ich stattdessen nächstes mal nehmen
Hey a question. I have a 36v 1000w motor and a 36v 4ah batterie. Which controller would you choose? (I made an ebike)
Hahaah echt nice wollts mir vor nem halben jahr fast genau so bauen.Man könnte ja diese kleinen USB C module nehmen wo man mit einen kleinen Push Button zwischen 5,12 und 20V wechseln kann.
The new Xiaomi Mi 10 Ultra can delivery 120watts of USB type C charging though
is putting 2 50w chargers together not feasible? all you need is the communication equipment for PD, you don't need an off the shelf PSU+PD board, you could probably find a PD board and use basic power supplies, or have multiple USB C ports on the vehicle
I'm trying to make a USB C charger for my mi scooter and i can't find the parts in my country
What voltage meter is that? Thx?
UT210E
Finally 😱
I wish companies that produce usb chargers would think about this effort. It would be nice if they produced a version that could deliver 42 v.
can you paralel 2 or 3 of them on a new pcb made by you and find the amps you need.. all you need is paralel em i think you dont need to make em comunicate... .. even 3 of them will work cool!!! this is my thinking but the safety and stability parameters of a less experienced user isnt my concern .. its project and everything can be on table as possible solution!!!!
now im waiting to see a video from you thats shows a solar panel charge a ebike! bet I can do it before you? challenge lol great video
why don't you go for 130watts Dell laptop chargers? maybe have a go at that
der neue USB-C pd Standard wäre eigentlich perfekt. Da bräuchte man bei einem 12s Akku nicht mal den DCDC. Hab aber leider noch keinen IC bzw. ein Netzteil gefunden, was 240W fähig ist. Schade...
Glad to have you back .🙏
Well done! Do you plan to revise this to the newest 240W standard of USB C? It would be sick to use one of those 240W gan chargers for my laptop, phone and ebike!
Here is an cheap 65w usb c charger. I feel bad recomending it here, because i get so many ads for it...
Ich kenne mich in dem Bereich nicht besonders aus aber vielleicht kannst du deine Idee patentieren lassen, falls es diese Art von laden noch nicht gibt. Auf jeden Fall wie immer ein richtig Hammer Video. Mach weiter so
Ups. Wusste nicht das du Deutsch bist. Ich habe einen 36v 1000watt Motor und eine 36v 4ah batterie an ein rad gebaut. Nun brauche ich einen Controller mit einen Gasgriff. Welchen würdest du mir empfelen?
für so wenig spannung kann ich den vesc sehr empfehlen. der hat direkten adc eingang für ein gasgriff.
USB-C is the king when it comes to charging
So i got a usb-c MacBook Pro Charger with 61w and it should work, Right?
yes it does, but be carefull though, with inefficency you can maybe set the boost converter to 55W...
excellent where are you in germany? i am in munich
Dang man such an innovative creation 🤩
Can you direct me to information on regenerative braking you used in the last video please.
Hallo Leo, ich schaue schon länger deinen Kanal. Ich bin selber sehr Technik begeistert. Ich bin aktuell am überlegen ob du mir ein paar Tipps geben könntest? Ich habe ein ca. 1400€ Trekking Rad von carver und überlege entweder selbst ein e-bike daraus zu bauen oder ob ich es verkaufen und mir etwas fertiges kaufen soll? Ist dein Fahrrad so legal?
nope, nicht legal. bau es nur selber wenn dus wirklich gut kannst oder bereit bist viel zeit reinzustecken.
Could you give me where I can buy that battery box? Look awesome.
That's cool I'd like to see this done maybe one day.
Great vid dude :thumbsup:
Schon Mal daran gedacht einen Bedini zum Laden von deinen Akkus zur benutzen ??? Das wäre echt interessant.
I use that exact same boost converter to take my 4000MAH 4S lipo's and charge my ebike while driving
hm... but that wastes easily like 15% of the energy... I dont know about that.
@@Pryside hello leo, i admire your work and video skills. Sure it wastes some energy. But for me its about using great energy storage potential i had laying around. I have these packs that are laying around not being used in my planes most of the time. And i simply want to increase the range of my crazy imortor 1.9 so i 3d printed some things to add more capacity when needed. In the city stock is fine.but when i need 30km of range i add all sorts of batteries. I have 3d printed a holder for 2 makita (hobbiest series drill) batteries and epoxied the dc to dc converter onto the holders to be able to charge the bike while driving with any sort of voltage potential that i can find. Like a car battery when camping or my stack of 4000mah 4s packs that i wired in series. It even heats up my batteries during winter times to perform better. I've also made a 10s pack from 4 lidl parkside 4ah drill batteries at about 2 euro per 18650 cell and being able to charge them inside my house serperately is awesome aswell. The losses are not the problem
@@Pryside so short answer not that much. From 30v to 42 volt it's not that much heat. Pretty efficient with 2 packs in series.
in a 2 hour day of riding they discharge from 4.2V to 3.7V per cell and then my voltage alarm goes of
Great videos very informative
Have you built any trikes ?
I have some ?
You're back 👍🏾
Quite a few mistakes in how PD works, but eh, not too important.
I do have some usb PD IC's that I was investigating using for this very application, albeit with a more programmable boost converter IC to allow the charge rate to be adapted according to the connected supply wattage
that sounds very cool. If i get something wrong feel free to write what i missed :)
Verlink mal bitte die Teile
Hi Leo! I bought the same DC-DC Boost converter that you are using... however when loading it my USB-C power supply always cuts out. I tried to limit the amperage with the righthandside potentiometer but it seems to have no effect at all.... the power supply immediatly gets overloaded and cuts out. Any idea?
i would connect the boost converter to a lab bench power supply or another battery and then charge a second battery with the boost converter and then set up the current with that as a load. then u can finetune the current to a degree where ur power supply doesnt cut out
Bro I need a 10kw bldc-motor kit for a ebike build
This is very awesome, I wonder if there is a way to do this with a 72v battery?
sure, they even make the same motor controller with a bit less amps and 72v. but that would only result in more top speed which I dont really need tbh :D
hi Leo, did you consider the AUKEY Omnia USB C Charger 100W? it only comes with the US wall plug though
yeah, not really suitable... 100w chargers will come, we will have more big laptops in the future that will require such chargers
NEW VIDEO FROM LEO !!!!!
Wonderful idea! Where we can buy it?
Hi Leo, Would it make any sense to use various USB-C 20.000mA powerbanks instead of a batterypack for an ebike?
not really too little output current would be possible if you can take out the 18650s and then make your own pack from them
What happens if you connect two chargers in parallel? Could you get around the 100W charger problem this way?
You would need additional circuitry to allow that, most regulators will not allow just plain paralleling of the output. But it is absolutely possible
@@callumkingunderwood Say I have diodes rated for high power. Could I do it then?
Does the new Mi 10 Ultra charger support the Power Delivery standard for up to 100W?
I'm guessing they are going to use a proprietary charging standart. But we'll have to see. But even if, the charger is not made for constant 100W. Its only enough for like 5 minutes, after that the charging will slow down
Servus! Wie stellst du die Ampere bei dem Boost Converter ein? Also was für eine Last schließt du an und misst du das mit dem Multimeter?
Ich hab einen großen Boost Converter mit CC Einstellmöglichkeit. Ich möchte 42V bei 5A einstellen, habe aber keinen Verbraucher mit dem ich das vorab bei der Spannung einstellen kann.
Kann ich eine starke 12V Birne aus dem Auto nehmen und die Ampere bei einer niedrigeren Spannung einstellen? Also sagen wir eine 55W Birne aus dem Auto, da stell ich dann 10V am Converter ein und regle mit dem Multimeter den Strom auf 5A. Würden die eingestellten 5A dann auch bei höheren Spannungen bleiben?
das ding hat 2 trimmpotis dafür. 42v kann man mit multimeter messen, dann halt an akku anschließen und die current einstellen
@@Pryside Okay danke mal für die Antwort. Problem ist ich betreib den Lader mit einem 1kW Servonetzteil und will nicht gleich mit der vollen Leistung in den Akku fahren. Mein Boost Converter lässt nämlich laut Aliexpress 30A raus ohne Current Begrenzung.
Werde es aber mal versuchen, der Akku kann das eh kurz ab denk ich, hat immerhin 1,2kWh. Ist ein Stihl AR3000 Rückenakku, 10S11P Schaltung.
Benutzt du immer noch deine China bms oder hast du gewechselt ?
du kannst kein bms kaufen das nich aus china kommt....
Leo Pryside ja mein Fehler ich meinte China Smart bms
240w usb c is now a thing... part two????
Thats pretty cool but looks like no manufacturer used the new capabilities yet and I can really find anybody who used this in a open source project.
Maybe in a few months we will see first devices dropping using that standard, I'll keep an eye on it
Sehr Cooles Video
Ist das nicht verboten?
USB Charger mit PD und 100W: www.hypershop.com/products/hyperjuice-100w-usb-c-gan-charger oder auch www.otto.de/p/i-tec-netzteil-universal-charger-usb-c-pd-3-0-plus-1x-usb-3-0-112-w-857828423/#variationId=857828424 sind wirklich schwierig zu finden, gibt's aber doch vereinzelt.
uff, würd ich gern mal im test sehn. glaube nicht dass die wirklich 100W dauerlast aushalten. Meiner kann auch 100W halten, für vllt 30 min. Das reicht für jeden laptop aber nich für n fahrzeug
Please make a how to build an e bike for dummies
Why just design your own charger and if it works, you can try to make a gerber file. (PCB Layout) Works with EasyEda. Then upload it to JLCPcb or PCWay. You can even ask them to sponsor your projects... 😀
thats quite a lot of work but since there arent any community projects that do that yet. It might be worth the time
@@Pryside I've done something similar before... I went to Alibaba and asked the seller for the files. I just needed to redesign some components (bigger capacitors, ...) and thats it😃
I had to write to about 10 different companys and with thwo of them I was lucky. By the way it was for a solar charger which I wanted it to be able to let a higher voltage go through...
warum redest du auf einmal englisch bist du nicht deutscher ?
Och ne englisch not so gut
Isn’t it „an ebike“?
true haha
@@Pryside ;)
It's possible to put everything into the battery case BUT I wouldn't trust those chinese pcbs, that they won't blow up at some point. That's pretty dangerous, especially near to inflammable Li-Ionen cells 😂
You are overloading your power supply this is stupid.
Leo du bist ein zu krasser Dude. Du solltest dich mal mit Elon treffen...
Jaa
Ej su alter knaker
Heilbronner Bastler 😂
Was versteht der typ nicht dass er deutsch reden soll
Mach wieder deutsche videos
Well. That was a waste of time.
