I am wanting to compile company's that sell high efficiency electric motors that we could use to do a EV Reverse Trike. My company is thinking about adding charging stations if enough interest develops. Heres one, any more? www.electricmotorsport.com/ |

Hi Dave, If I was going the RT Electric route I would be doing business with a China Company called "Golden Motor" goldenmotor.com, They will set you up with a 10,000 watt killer, 100MPH, and they can handle Lith-ion Batts and wiring kits, NO gears, I would love to go this route except for the distance factor, some of these bike runs in California are 1 hour+, one way, and on the weekends I love to cruise PCH along the coast, think Mustang IFS. Good Luck in your ventures TomyJ |

I'm considering the 20kw motor for mine. I don't know if I want to bite the bullet and buy the Li batteries at first, or use car batteries to begin with until I have proof of concept.

The "Proof of Concept" has been well tested out there. If I were doing an EV I would have to go with Li's and only Li's with a very good controller and cooling system. And anything under 72 volts is also not worth trying. There are a lot of books on choosing an EV system, a trip to a library would be a good start. Car type or Deep Cycle batteries are HEAVY. Then the efficiency cycle gets worse with each recharge. If you continuously run them down lower than 70% charged they have a higher failure rate. This is a EV motorcycle I almost bought. It blows a ZERO away. zelectricvehicle.com/22.html But $14,000 is what held me up from buying it and then I retired so no more commuting. |

I should say, I meant personal proof of concept. I know they work, but I'm kind of at a point where I don't want to spend a bazillion dollars to make something that ends up not working. I know I should spend the money for quality equipment to begin with.

I had a cousin that had a Corbin Sparrow EV trike. It was a blast to drive but the range was too short due to only having room for about 14 VERY HEAVY Lead Acid batteries, two in parillal and 7 sets strapped in series for about 84 volts. But IF he still had it and I were to buy it cheap, I'd spend the $6000 to upgrade it to about 21-32 Li battery packs (20-30KWh) @ 96 Volts.
The new Corbin Sparrow 2 will have Li tech, IF it comes out.

From what I've learned, if your final design doesn't include lead acid, it isn't even worth building a prototype with them due to the fact they are ~5x the weight and volume of lithium. In fact, if you are sourcing lithium batteries from salvaged hybrid vehicle the price/USABLE Kwh is surprisingly similar. Minimal BMS required if you charge it slowly enough.
