  1. Regen circuit for DC Series Motor in a book!

    Controllers
    Hello, I got a small book on Regenerative braking with DC Series Motors, it was written in 1997 a time when the Warp9 and LiFePO4s did not exist, it was intended to be used with the Advanced DC Motors and PbA batteries. Here some book's excerpts: " Can be used with present day electronic...
  2. Conversion of Adv.DC Series Motor into DC SepEx

    Electric Motors
    Hello folks, I'd like to get REGEN out of a DC Series Motor. DO you know what should I do to convert the motor into a DC SepEx Motor? The Motor is Advanced DC Motors, which doesn't seem to have internet presence anymore, it's hard to find his motors. Thanx a lot, ekthor
  3. How can I install a regenerative brake that operates separately from the controller??

    Blog
    How can I install a regenerative brake on my EV that operates separately from the drive controller? I converted a motorcycle into an EV and used a motor controller that is not capable of regenerative braking. What i'm looking for is off the shelf products that I can wire it to bypass the...
  4. 4-Wheeled Regenerative Braking

    Technical Discussion
    First post around here so go easy on me. Sorry about the blocks of text ill try to organize it. Intro Hello I am a member of a team that is assisting in the development of an student designed electric racecar. More specifically we are assisting in the design and prototyping of the motor control...
  5. Charging by Using Regen

    Batteries and Charging
    I have a crazy Idea, if it has already been mentioned in another thread feel free to delete this one. In a 3 Phase System: Could you Disconnect the Wires from the Controller to the motor and then feed Grid 3Phase 50/60hz ~415/450VAC into the same wires? The Controller would think it was getting...
  6. Regen LiFePO4 with PM motor

    Controllers
    hi guys, I'm struggling to understand if Kelly PM 48V controller can regen Lithium LiFePO4 or LiFeYPO4 batteries. I have an parallel hybrid boat with a 18HP diesel on the same axel as the PERM PMG132. I asked Kelly but I am very confused by the answer: - they replied that the regen tension is...
  7. Gear Shift rattle during deceleration...

    Technical Discussion
    While I've read along for a long time, but this is my first post. I'm converting a 1981 Jeep CJ5 and got to drive it around for the first time last week. I have a number of things to work on. It runs quite fine in all gears going forward and reverse. However, when I'm coasting or going...
  8. building a hybrid, maybe

    New Member Introductions
    I really want to build an electric car, but it is not uncommon for me to make long trips, sometimes traveling more then 200km several times a month. because of this i would need to have a separate ice car to make these longer trips. Something that i think would be a waste of money, why spend all...
  9. Adding Regen to DC? Not for range...

    Technical Discussion
    I live in the foothills of SoCal and I notice that while I drive any of my ICE vehicles, auto or stick, I use downshifting to control my speed. I do this for traffic or hills. Since I am seriously considering a DC electric conversion, I would like some resistance from the drivetrain when...
  10. Regen with a wind generator?

    Batteries and Charging
    So I wired a wind generator to a controller, battery, inverter and can power a battery and light a 40 watt bulb using a hand crank I made. Yippie for me. But the thought can I connect it to the front of my motor and regen 144V back when braking? How would I connect it to the 144V pack without...

    All EV Conversions and Builds
    Hello! I'm very new to the world of EV conversions and car mechanics in general. Basically, I've ridden bicycles my whole life while waiting for the day that I could afford a practical planet friendly vehicle. Well I'm now 30 and tired of waiting, so that's what brings me here. For a donor...
  12. Coupling Solar Panel to LiFePO4 batteries

    Batteries and Charging
    Hi everybody, this is my first thread on this forum. I have read a large bunch of thread here and took a couple of notes and links that you have shared. It is very interesting how much people care about the Oil depepdancy and are ready to invest in ways to eliminate this dependancy. I am a...
  13. Dual Drive System!

    All EV Conversions and Builds
    :) My students and I have begun a "new" type electric car project! It will be brutally simple. We have replaced the rear axle on a '91 Geo Prism, with the rear axle from a Subaru Justy. The Subaru rear suspension is especially well suited for this format. The Subaru rearend is floating with CV...
  14. AC Controller/motor matching?

    Controllers
    I have noticed that all ac setups come as a matched unit. If i am able to build an AC Controller based on an upgraded Circuit cellar design, Will i be able to match it to any ac motor that fits requirements? Also, Has anyone looked at used traction motors. They seem to be readily available. LAST...
  15. electronic braking with alternator?

    Technical Discussion
    Can anyone tell me how much spinny resistance (tech word) an alternator has when it has no electrical load connected? if it is the same as a permanent magnet motor being used as a generator, it shouldn't have much if any resistance. i've looked for this idea on the forums here, and didn't find...
  16. AC vs DC regen braking

    Technical Discussion
    In the news forum I saw this post: Which sounds like the opposite of what I have read in these forums, so I followed the link, and it says Did I misunderstand? Which does regen better, AC or DC? Or is that too simple a question?
  17. Clutches...

    All EV Conversions and Builds
    It is my understanding that DC motors are not very good candidates for regen braking. This being the case, seems disengaging the motor entirely while going downhill would help in coasting situations, letting gravity do the work. Instead of pushing in the clutch pedal to coast, has anyone tried a...
