Dear colleagues,
as suggested by fellow forum-member brian_ in the new members introduction, I will start a thread for my EV-Conversion of a 1954 Renault 4 CV. For those of you who are not familiar with this nice little french car (rear engine and RWD), here's a picture together with its great-granddaughter Zoe, who is already fully electric and won't need any surgery ;-):
My plan is to document the whole conversion process here step by step.
With this first post I'd like to give you an idea on the rough lines of the conversion. My plan is to keep as much of the originality and driving dynamics of the original car as possible. This will mean that some key values will have to stay within a band of +/- 10% of the original car, e.g. power output in KW and weight. I might make an exception for torque though ;-)
Also for the same reason I want to keep the clutch and gearbox, with the added value of some "classic" feedback and noise. This will be the main difficulty on this car, as the flywheel/clutch assembly is integrated into the engine, so the gearbox comes without a bell housing... so there might be the need to fabricate a custom solution there. I will talkt to you later about that and include some specific pictures for better understanding.
But to start with the simple things, here you can see how easy it is to separate the drivetrain from the chassis on this type of car:
For the technical details, here's my rought plan:
Battery System:
4 x Tesla Modules in 4s configuration, most probably one in the petrol tank compartment, two in the back and one in the front.
No decision yet on the BMS and charger.
Motor:
FIMEA Engineering N50D1, 15KW @96V, 140 Nm of torque, 7500 rpm max.
Controller:
Curtis or Sevcon, tbd.
Looking forward to all your questions, comments or suggestions - I might also have some questions for you too while moving along!
Best regards,
Remi (R4eCV)
PS: Not sure if any of you ran into a similar problem: I had originally written a much longer text as the one above, but once I got to submit it, the system had logged me off and I lost all of my work. Note to self: The next time I will preparte the text offline and then paste it into the forum!
