| Post subject: | tesla motors |
anyone looked into tesla motors apparently this electic engine does 250miles per charge puts out 185kw can accelerate faster then a ferrari with an engine that weighs 30 kilos this sounds great but then i found out the battery weighs 400kilos  anyone thought of or even heard of this before is a mini conversion possible???

my mate showed me that site ages ago it's so cool!  :D:D. i dreamed of putting the motor in a mini something like 14 or 20 000 rpm mmmmm
cheers |

Good option but what dose the running gear cost if the price tag is $98 thou

The Tesla motor is a AC motor wich can do allot more rpm than a DC but the cost is allot more. The motor can do around 14000 rpm have a look at AC Propulsion they sell AC packages also have a look at youtube at the tesla interviews. Another good AC conversion/ Manufacturer is Wrightspeed who have an arial atom (X1) with a AC Propulsion motor there is some good fotage of this on you tube also. A more affordable conversion is DC they dont rev as high (6500-7000rpm) but with the torque these motors produce you dont need them to rev so high you just need to gear them correctly. Netgain warp motors are the best dc motors, advanced dc motors are also pretty good. These motors are rated totally different to an ICE (internal combustion engine) with the continuous rating being what they can continuously produce with their max power usually 4-5 times this rating, the other great thing about electric motors is maximum power is at 0 rpm so from the get go you have enormous amounts of power. batteries are the limiting factor in electric cars, battery technology is improving and prices are slowly coming down, this is why the tesla is so expensive. I can garantee that nearly half the price of that car would be the batteries. I am doing an electric mini conversion at present but dont want to give to much away as yet, all i can say is it will make allot of these 16 valve conversions look like dinosours Phill |

Phill An electric Mini sounds awesome. I have thought about doing that as a great little commute car. Its on the list with about 100 other projects I'd love to do!! Shame they only made a few of those fibreglass minus shells cause that would be an excellent start. Maybe when I get round to having a crack at it the batteries will be up to scratch. Will be very interested to see your progress. Cheers Madmorrie |

Phill , would it be possible/feasableetc to utilise a small turbo deisel generator and then reduce the amount of batteries ? Basically enough to get you going from stop and run for 10 minutes or so and the generator kicks in and tops up as required ? Sort of like a hybrid but not really . |

This is definitly possible. http://www.worldcarfans.com/2060724.006 ... ctric-mini. I will only have batteries though, i guess it just depends what your application is. I have designed the car to get me to and from work each day (about 100km). overall the car will only weigh 80kg more than a standard mini but have around 100kw from the get go (the advantages of electric motors) |

Yeah that AC Propulsion setup is sweet, just too expensive. Was over 20 grand + shipping for just the motor and controller. Probably more than that now. http://www.ausmini.com/forums/viewtopic.php?t=6243&highlight=propulsion |

Cooper69, In your sig it mentions 156volts, 700amp and 96kws. Shouldn't 156volts with 700amps make 109.2 Joules, which would be 109.2 kilowatts, as P=IV. |

the motor im using is about 85-90% efficient thats where 96 kw comes from |

Ah yes, fair enough. |
