Ultracap powered electric vehicles.

Just starting the thread, but I hope to help lead it also...

The 440v US power mains can deliver up to 50 amps before blowing a breaker, so using resistance and a step down transformer people should be able to get a charge in the garage. The trick will be using high farads at lower voltages. example: 125V-3000F cap bank charging off the grid @ 125v and 0.01 Ohms resistance, the cap bank would take about 2.5 minutes to charge and have a maximum power dissipation of 1,562,500 Watts. That sounds like quite a efficient electric scooter ride to me...

I'm seriously considering buying a few of these 2.7V@3000F ultra caps this week, but I would need the help of some of our electronics gurus to design some of the the needed electronics. I'm thinking 5 caps in series for 13.5V@3000F. Anyone interested in starting a cooperative EV thread? We would need to design a self regulating charging system, and a POT controlled discharge system. Maybe even a regenerative braking system in the future... Anyone interested? I would really like to have a 20 horse electric car out on the road some day soon! Or a one horse electric bike at the very least!

I payed 100$ a piece for my bcap 3000s  and they are worth every penny , I hear the prices are going to drop soon too. These have been banked with  H16 series Trogan  batteries in  the MotorCoach.  This is all  charged controlled with  2  OutBack MX60 and distribution/inverter setup.

These kinds of caps are the future when it comes to energy storage .


Someday I would like to put together something like this  but with caps

this is the project for now. Shwinn1000

You have no idea how releiving it is to know you're on the project already IH...


I'm waiting for the coming price fall myself...

I'm thinking about buying 5 of the bc3000 caps to run in series for a 13.5v max output for running a 12V brushless DC motor on a bike, but between the charging regulator and and propper pot control of the voltage to the motor I'm quite worrried about ruining expensive components and/or dieing. Anyone who can help design a (cap bank moddable) charge controller and/or speed controller system could really help those of us who are not a electrical engineers power through this project quickly...

That and I'm going to crush some cans... 3000F@13.5V dumping through 3 turns of copper tube makes quite the scene.

If you are going to build a bike , this is the motor to use . the cost is high but let me tell you there is no better in this size motor. Here  are some links for bike and scooter stuff. This has its own controller and it will not burn with caps. I have fully tested it with bcap3000s . My goal is 2 of these on the scooter on a dual mount.

Good link for bikes

If you like hub motors these are very good

you can buy controllers for about 30 bucks
and 10 bucks for a throttle .Here

Ok now  for brush motors you use a hall effect and for brushless motor you use 5k pot thottle
