My first ev-conversion
Skills: semi-professional car mechanics, welder, metalworker, system engineer, programmer, ICT-architect
Required range: 10 KM/charge
Perf: 40-50 KM/hr
Budget: 1000 Euro's
Hoping to get it street legal which is supposed to be easier for conversions of cars registered before 1998 as the official institute in my country (The Netherlands, Europe) assured me.
-Renault Twingo 1994 obtained as a real bargain for 250 euro (tip-top shape apart from a defective crankshaft bearing). It's a small car but will only need to be used as a 2 seater with the batteries covered in the extended back having the seats removed).
-Hyster Forklift 48V motor with fuse, emergency switch, controller (but considering the gate driver part of Paul and Sabrina's Open Source controller with my own microcontroller, 68HC11 based (as I built most of my robots with them and it has programmable pwm pins as well)) although seriously considering an Altrax controller as well (laziness).
-Got me some second hand agm batteries already which for the initial requirements might still be sufficient (I heard the other day that the company that I work for seems to start a new development on Lithium air batteries but I doubt I will ever get my hands on any of those :-)
-Collecting transformers for a custom charging managent system (but maybe my laziness wins as well there causing some strain on the budget which my wife guards so thoroughly).
-an affordable vacuum system for the power brake assist (you knew that one was coming I guess)
- machining down the existing hubs from the clutch and the drumbreak from the Hyster and adapting them to the lovely joints (still keeping an eye open for those).
no power steering required with the old model I got.
Bought the car a week ago, fuel tank, exhaust and engine are gone by now, cleaning and small exterior repairs on the way, I got myself a service manual for the car today as well.
If the motor indicates 48V is that for a parallel setup ? And if I serially connect the field and armature coils, does that mean I can run it on 96V ?
I read about the robustness of the forklift motors and tend to go for 6x12V and indeed serial anyway but just curious.
thank you all for creating such a wonderful and resourceful forum.
ok I need some cleaning on the motor too....
