So, this is the first video about our BATTERY system. I think it is a little more complex than I thought, so there will be a couple more videos about the battery upcoming soon. This is an adventure! 😂 Let me know what you think and if you have suggestions please!
did you draw that whole thing in cad? who's doing most of the work on the vehicle? are you assembling the pack by hand? watercooling? why not use hub motors?
also, do you know anything about electric motors and motor design? I wanted to get someone skilled to look over my axial flux BLDC motor design in CAD before machining it, it uses a halbach array on the dual rotors.
lastly I have something to share! you should look at getting an electric unicycle. there's plenty of videos here on youtube and you can buy one from ewheels or euco.
I am a physics student in university, and I am also into assembling EVs though I don't like 4 wheelers lol. I even assemble the battery packs and weld together parts to the frame.
thanks if you reply, your husband is a lucky guy! very beautiful and smart
@@Blox117 the cad model presented in the video is downloaded from a website, but we are creating our own from a Laser scan right now in solidworks (see episode 3 I think). We are working in our garage - that's what people do in america right? 😂 so we are manually disassembling and assembling them ourselves. No hub motors (see episode 2) because too expensive and more complicated to control. Also, a project goal is reusing as much as we can. The batteries will be water cooled. I am not an expert in motors, but batteries 😊
@@ElectrifiedVeronika no I work in my kitchen cause i dont have a garage lmao
Cobalt is used in fossil fuels.... but nothing is said about that though...
Wow it nice to see a woman is in to project like this
Dr. Veronika, great update. Enjoyed the battery information. Very thorough thought process on the right batteries for the "Gilmore Girls" Jeep. Look forward to the next step of the build. Thank-you.
cool, well thought out build
We are getting there, but I am sure we will change our mind again. 😂
Great use of modern engineering tech support tools, Scanning, CAD, 3D Print, Simulation all tools we dreamed about are now here and largely affordable. I am disappointed so few young folks see the opportunity in these tools to create anything. Your mini Lectures should help spur more folks into these science tools. I hope. Good Job, Dennis
Thank you Dennis for your kind feedback. I hope to create more mini lectures here pretty soon to get into more details. It is so much fun and a big learning I want to share.
@@ElectrifiedVeronika I would love to get In-Wheel drives for my 2014 Corvette to create a Retrofit Hybrid. Any ideas?
Thanks for this video series. It's been a good starting point for my next project. I'm going to be on the lookout for a cheap car with a broken engine now.
Wohoo, let me know how it goes and if you need anything!
Love the series! Not only because you explain things, but because you have to deal with the exigencies of running an EV in the Midwest.
I'm sure you're tired of hearing this but can you help me with the math? It has to do with the relationship between pack voltage and capacity. Using the Tesla S pack, although I know you didn't for the GG Jeep project, but because everyone seems to agree on the configuration and the end result AND it is the pack I used to check my Excel spreadsheet formulas when I was playing around with pack configurations.
The Tesla S module has 444 18650 cells in a 6s74p configuration resulting in 22.8V and 5.3 kWh (I actually came up with 5.74 kWh for some reason, probably resistance). Adding 16 of these modules together, I believe in series, results in 364V nominal, 403V max, and the 85 kWh pack results that we all know and love.
My question is: if you sum the voltages by wiring the 16 modules in series, how can you also sum the capacity, which would otherwise require a parallel connection? Is there something special that happens because there are the three tiers, cell, module, and pack?
By the by, the only clear conclusion from my pack configuration exercise is that I am playing checkers and @elonmusk is playing chess.
I'm so excited for the next video. been watching them once I found them. I really hope it turns out real well and can hopefully become a reference for others who want to convert a jeep. Thanks so much.
Thank you! I am pretty sure this one will not be the optimal one, but so much learning from the first prototype so I can come up with a goof reference in the next conversion 😊
🫶🏻🫡
im about to start a conversion!!! this videos are so helpful!!! I went for the 1 motor turned 90 degrees :D
Awesome, thanks and that's cool to hear! Please let me know how that goes, which car do you convert?
@@ElectrifiedVeronika I’m converting a Land Rover Series 2a 😁
You both are well versed in electrical engineering configuration of EVs especially the Jeep Wrangler 🔥🔥🍿🍿🎥
Thank you, we are trying our best 😊
I love this video really easy to understand. I see you have the fomoco 48v 2kwh module on the bench.
Currently working on making a easy breakout board for that module and using them in my project.
Wish you the best !!!!!
This has been a treat to follow along so far, looking forward to each upload.
I was wondering if you’ll do a recap video towards the end with the full cost breakdown of the project. I personally would even love to see costs associated with the 3D scanning, test components, and everything in between to see a true project cost outside of just the cost of the parts in the finished build.
I’m hoping to copy you one day and convert a 94 daihatsu hijet to electric!
I WILL! The only thing we did not really track so far are our real "working hours", I would estimate that. It will definitely be the most expensive conversion in the history of conversions if we include the 3D scanning, but why not make this comparison 😂😂 I hope your "copy you one day" is sooner than you think. It is a fun thing to do with lots of learnings! I think this 94 daihatsu hijet could work pretty well! Keep me informed please!
@@ElectrifiedVeronika Haha we'll see, I'd be starting from near scratch, I've only ever done some minor tinkering with motors and batteries.
Your series is especially exciting because it seems like you are approaching it the way I'd hope to.
Given the cost of the 3D scanning, do you feel like it was worth it? Have you been using that scan very much?
At the end of the day, if you want to recoup some cost you could list it for sale and I bet some VFX artists or studios would buy haha
@@hogan_xyz looking forward to seeing how your project goes. Right now we have problems/effort to convert this point cloud scan into something usable in solidworks. It's basically reverse engineering with lot's of manual steps. But there might be a solution that will lead to a good model faster, more to come soon! 😊 I wanna keep the excitement up right? 😂 As a private person for one prototype you would probably not want to do the scan, but for scaling up and converting a fleet for example, it would make a lot of (financial) sense, I would say.
I thought this was a big channel or the following for this series was blowing up and had a massive following. Great video and I hope lots of people learn from your videos because you’re doing this. I guess YT alg showed me this cuz I was looking into batteries for my longboard. This is a whole new project. Much more difficult to convert a car. I gave up on converting a motorcycle in high school and I wish I had kept doing so. The skills are worth it!
Thank you for your feedback, let's see if the channel grows more 😊 The best thing about this project is the learnings!! 😊🙌😊
Ev swaps and conversions have a electrified future.
This is possibly the best-researched conversion I've seen so far! I'm on the fence to do something similar, but with a station-wagon like an older BMW 5 series or Mercedes E class - the one type of car that I think would benefit the most (low drag, long wheelbase, big engine bay).
Are you doing 7X 16S2P for the batteries? Based on those LG pouches I'm guessing it should get you a 32kWh total pack, so about 80-100 mi range in the Jeep? Looking forward to the build!
THANK you SO MUCH, that's so wonderful to hear. And your project sounds cool too, let's do it! 😊 About the batteries, lots of uncertainties right now, working on it!! BTW, 2 days ago got 12 used modules again - now disassembling, testing cells, but also looking into some other used batteries again. Stay tuned, and sorry for not having the details ready yet. We are aiming for 60kWh total capacity.
What motor have you used?
Cascadia Motion ➡️ All the infos about E-motor and inverter here: th-cam.com/video/2FtHQ-rrGAk/w-d-xo.html
Amazing channel! Really great info, thank you so much for sharing!
Thank YOU so much for a proactive and positive comment! ☺️🙌💪 filming today!! ☺️☺️
I worked on dump trucks in Australia and they were diesel v 12 Cummins power train and rear drive 3 phase 400v ❤️with large alternator charging systems, dynamic brakes with hydraulic to all wheels .ok
That was great Veronica
Very Nice
love the infos. very nicely explained. what is the aspect/size of each battery cell? also what about cooling the batteries?
Thank you! The dimensions of the LG pouch cells without tabs are 10.63" x 4.13" x 0.5" . We changed our mind on the cooling part, so we did not include it. Coming up soon! Suggestions? 😂
Enjoying watching your videos and would love to get an older CJ/wrangler and do the same thing. But 1 small note a JEEP isn’t a car . OlllllllO
Hehe, I realized that I have to be careful. Used to call the F150 a car which is a no go also 😂😂
@@ElectrifiedVeronika 😆🤣😂 I used to drive a MJ ( Military Jeep) 1st and then after I got discharged and sold my mustang. When I moved home I bought a CJ (Civilian Jeep) . So I’m kinda a JEEP nut . lol OlllllllO
Loving the videos!
Thank you so much, that's great to hear!
Hi V, thank you so much for your Videos. They've been so informative. I have 2 2012 SUV mercs which is like to convert in the future. I have 2 questions
1st is how do I intergrate the the new ev to the original electrical system of the car without having to change much. I'm Guessing I might need to keep my gearbox or atleast the transfer case.
Is also light to get atleast the same power or speed or if my new motor. How do I choose what motor to use.
Thank you very much for your videos. Can't wait for the next one.
Great video! Looking forward to your fabrication of your battery modules.
Was using existing Tesla modules not an option?
Yes, we heavily considered them but the pouch modules we got fit better with the voltage we needed and the space we have. We really didn't want to "fill the trunk" with modules and wanted to keep most of the batteries out of the cabin. With the Tesla modules we would have needed quite a few to get to the 400VDC that we wanted.
Thank you for your feedback! I am a big fan of cylindrical cells and if we wouldn't have gotten access to the used LG modules we would have dived into that more - probably would have needed to go the route to configure our own "Tesla cell based modules" too. As Don mentioned in his reply, we have restrictions in space and voltage level and we want to distribute weight and not have it all in the frunk. And this modular, reconfigurable pouch cell concept seems to be a really innovative, creative, challenging but hopefully doable solution 😊 Stay tuned and always happy to receive questions, suggestions, talk about ideas.
Any of the Tesla modules (there are different formats in different models) are awkwardly large to fit in the vehicle, and none of them can be readily re-configured.
Hey if I can be of any help with your guys project just finished my 2008 Beetle Electric Conversion and learned a lot
Would love to learn from you! Maybe could you reach out per email and we can jump on a zoom call or something. Electrifiedveronika@gmail.com
WOWW 😍 you impress me all the time 💪👌, i live in north, so i wonder if you can retrieve the heat from the cell and heath the cabin ? Like server in some place...
awesome job Veronika, I look forward to converting my jeep 2007 🤩
thanks a lot for all your video.
Thank you for your comment, I so much appreciate that, so great to see that positive feedback! GOOD IDEA, energy efficiency is the key - this is what Tesla does with batteries, but especially the E-motor - but this requires a special heating/cooling system which is outside of my expertise. More to come soon about these aspects!
@@ElectrifiedVeronika wow, didn't know that tesla does that, thanks for your response, i follow you from Québec (Canada), you are so great, so chrysler in going to hire you becoming chief engineer EV 🤣👍😍, have a nice day Veronika
There isn't a useful amount of waste heat from the battery in winter conditions. There is some waste heat from the motor and controller, but it's still not enough for cabin heating.
What about cooling/heating of custom made battery pack.
The batteries will be heated and cooled through an active thermal management system with liquid cooling through cooling plates attached to the bottom of the modules. We will also make custom battery casings that are waterproof. More on that soon! 😊
Soo cool but way above my head.
You know dear that I am watching from the Philippines,and as you know we can't find EV motors locally,therefore 3phase induction motor is the option,my question,can we use it economically and technically feasible?
Hallo Veronika ! Erstmal schöne Grüße aus der Heimat ;)
Bin schon gespannt wie es mit dem TJ weitergeht ! War 31 Jahre mit Jeeps unterwegs und bin im Herbst 2020 vom Unlimited Wrangler auf ein Elekrto-Auto umgestiegen. Leider gibt es ja nix von Jeep, daher erst mal ein BMW i3. Ein Umbau eines Jeep auf elektrisch spinnt schon länger in meinem Kopf herum....mal sehen ob das hier in Österreich realistisch wird. Viel Erfolg und Spaß bei deinem Umbau ! LG, Gerald
Hallo Gerald! Vielen Dank für die Grüße aus der Heimat, bin in einem Monat mal wieder in Österreich, freu mich schon! Schau mal bei „ECARUS“ vorbei, die konvertieren Pinzgauer Trucks zu elektrisch plus solar in der Steiermark! Die wissen genau was es braucht um dann auch auf der Straße fahren zu dürfen! ☺️
So if I understand it your choice of 400V came down to IR losses, the higher the voltage the lower the loss but 800V was impractical to achieve? DId you do any analysis on the effects of voltage on the motor?
Yes it was two things. One was for the losses but there was NO way to get to 800V with our modules without really removing the individual cells from this double slice that is the smallest unit. Yes we could have bought 800V EDrive from Cascadia but stuck with the 400V because of the battery configuration.
I haven’t gotten a chance to look at the other videos yet, but how does one account for safety in a conversion? Not sure if a short/fire would be of concern for the batteries from thermal run way. Great video and thanks for sharing
I’ll make sure to watch your battery fire video. Just saw you have a video on that
Yes, it is of course a concern and we will try to make the batteries as safe as possible. We will share our ideas in an upcoming video.
gratulalok az eloadashoz de van egy kerdesem miert nem hallani a super capacitor battery -rol kernek valaszt !!!
This may be answered in a future video, but what is the return on driving distance per weight of battery pack? For example, you said in a previous video you need about 220kg/500lbs to equal the original Jeep weight. It would stand to reason that if you used less batteries/less weight you could go further because the power is not eaten up by more weight. But if you add more batteries/more weight, your efficiency goes down, but you also have more power. So is there a sort of break-even point where adding more batteries would actually harm the rate of return?
Very well analyzed. Yes, there should be a break even point and will will figure that out in our virtual environment where we can play around with all those specs. I will include that in upcoming videos, glad you are bringing that up. Had the same thought when adding a trailer to tow.
Hello Thanks for the video, Can i ask you some questions please ?
The on-screen text giving the weight of the Jeep's original starter battery is incorrect: it says "80kg (40lbs)", which could have been intended to be "40kg (80lbs)", and more accurately "40 kg (88 lbs)"... if that battery is actually that heavy. More likely, it's a BCI Group 34 battery at about 18 kg (40 lbs), so maybe that's what you intended to post.
Should be 18kg, 40lbs ☺️
When assembling your 400V battery, some precautions must be taken to avoid short circuits (I hope).
Indeed, once assembled into a car, the opportunities to touch a positive to a negative are likely to be prolific.
I hope I am going to see that this is taken very seriously.
Battery fires are very unforgiving.
They are essentially chemical fires.
Might we be planning only for the good times?
Has anybody thought of using the space which surrounds cylindrical batteries to contain fire-suppressant chemicals - just in case the worst happens ?
CAN YOU USE D CELL BATTERIES ? OR 9VOLTS ?
Did you add the weight of the liquids like oil, gas, and coolant to your calculations? (I assume you did)
So, the liquids like oil, gas are included, but we estimated the liquids for the battery right now, more updates once we have the real battery system installed 😊🙌
Please don´t touch modules with both hands at the same time, no matter how safe you think you are :)
I agree, safety is very important when working with batteries! 🙌
The state of the art is lithium iron phosphate now, rather than lithium ion
State of the art in the automotive industry are lithium ion batteries with NMC cathode chemistry. Lithium iron phosphate is a lithium ion battery with a LFP cathode chemistry. The latter is on the rise because of the scarcity of cobalt in NMC batteries plus other benefits like safety and longevity, but right now on the streets you would mostly find NMC.
@@ElectrifiedVeronika ah ok. Very interesting. Thanks
Strangely, when you talk @2:36 about manufacturers using existing (designed for ICE) platforms you illustrate it with an image of vehicle designed specifically as an EV.
Good observation! ☺️
Plot twist it’s going to run on a highly efficient diesel generator so it’s technically still electric but EV is getting a $3,000 subsidy from Exxon for each vehicle sold now. Along with an undisclosed settlement for signing an NDA
