How do you set up a charger for a lithium-ion battery pack in an EV conversion? Let’s learn together. The first step doesn’t even have to do with the charger, it’s about the batteries. In this video we’re talking about how to balance lithium-ion batteries, and then how we’re going to charge them.

Get exclusive behind-the-scenes on my Patreon: patreon.com/OffTrackEngineering Welcome back to another installment of Project Acte. My 1993 Honda Acty Kei van is being converted to electric. In this episode we're talking Tesla batteries, how I bought them, how I'm planning to contain them, how I'm going to mount them to the van, and then how I'm managing them.

Good design is visual storytelling. It's a way to communicate that is strictly visual. When it comes to automotive design, there are three literal pillars that largely define the form of a car and are a symbol of the car's primary function. In this video, we explore the history of car pillars and how designers use them to set apart certain models or entire brands of cars. 0:00 Introduction 1:15...

    Hi, when you and others build an electric car and put the battery packs low to the ground, aren't you worried about going through a deep puddle. If the battery pack isn't 100% waterproof then something bad will most likely happen.

    For a channel that has engineering in its name there certainly isnt much engineering going on. Using a hand drill to drill sidewards holes, claiming there are torque "specs" for a prototype motor plate to attach to a motor, using hex headed bolts for said attachment without a washer(s). None of this even mentions the fact that he is taking the path of the most resistance by flipping the transmission onto the cardboard instead of laying the cardboard on the transmission. Not much in the way of work flow in fusion either...so much for taking a head on picture, importing it into f360 then scaling it to size and making the appropriate holes in their location. Its not hard nor does it take any substantial amount of time. As a user of Fusion360 since 2019 I can do something very similar (and have) in very little time. Quite frankly this video could be a case study on exactly how NOT to do things. Was anyone else astonished by the shear amount of extra work created by the guy in the video? So much for working smarter and not harder.

    3:00, spray the flange with machinists ink and carefully place the transmission on the paper, or spray the flange and tape the paper to the top of the transmission and flop the paper over like a hinge to the face of the flange, or take thin cardboard and place it on the flange and hit the carboard with a rubber hammer making an impression from the flange to the cardboard. 13:30, toaster oven next time for even heating.

    Very nice. I always wanted to EV swap a kei car. Specifically the deckvan keis with both van and truck bed. I originally had considered keeping my CRX transmission for the same reasons as you for my EV conversion but since i was using the Nissan Leaf motor, I found the axle coming from the Honda transmission wouldnt clear the motor and ended up using the Leaf single speed transmission instead. Make sure your axles will clear the motor with the transmission. The benefit of mating the transmission is stock axles can be used but if they dont clear, you'd end up needing an intermediate shaft which is just custom axles all over again. What do you plan to use for batteries?

    Real EVs only have one gear and don't use a transmission, clutch or flywheel. It's just extra weight and something complicated to break.

      @@damensutherland7081 no. Gears change torque but electric motors have max torque at all speeds so gears aren't needed.

    • @Daweim0
      @Daweim0 11 днів тому

      Electric motors don't have max efficiency at all speeds though. EV manufactures probably put a lot of testing and thought into choosing the perfect gear ratio, not really practical for a DIY project. It also might be easier to keep the transmission instead of mate the motor to the drivetrain (especially if the rear differential is part of the transmission like it is in Sambars)

    As someone else commented the axial load needs to be addressed. The old gas engine has a bearing design that can take the lateral pressure from the side load that happens every time you step on the clutch. Those clutch forks put a few hundred pounds of sideways force on the electric motor bearings which probably has not been designed for and you will have premature bearing failure.

    I am concerned about no pilot bearing for the transmission shaft inside your flywheel hub. Also I am concerned that you are relying on the HPEVS motor bearing for the axial load caused by the the pressure plate engaging the clutch. I believe what is needed is an additional thrust bearing to take that axial load.

    • @blackterminal

      I have no pilot bearing. Just wouldn't fit after adapters etc. My car though hasn't left the driveway. Legal costs are high in New Zealand to make a conversion road legal.

    an inch thick bellhousing plate is insane lol. Good news it wont flex, thats always a plus. Other than that, I thought the AC 50 motor would be smaller, glad I didnt pick one up for my project. I am converting my dads 1979 Kawasaki kz650 SR into an electric bike. Going to build a 20kwh battery pack for it and have either a mid drive motor or a hub motor. Depends on the battery size and shape of it. I may have to build two battery boxes and link them together via giant cables. but either way it will work out to be around the same weight of the original engine and trans, and theoretically it should go somewhere around 250 to 400 miles a charge. Zero bikes are 16kwh max and get around 300 miles per charge. So I should be a bit better depending on the output I set the motor up with. It wont be a 75kw bike, more like a max of 30kw of output.
