I just started to reverse engineering my e-mehari electrical traction system. The e-mehari share most of its components will bluecars.

• cool:
  • very cheap: you find e-mehari with broken battery as low as 3000€ and working one for 5000/6000€ example:https://github.com/Tux-Solar/emehari-bl ... ndhand.png
  • passed all French certification to drive on the road (as inspection do not check batteries you may change them without loosing your right to drive on the road)
  • traction battery is installed under the car and easy to hack
  • it's a funny car, you may remove: windows, roof, door, ...
  • based on bluecar it is very easy to find spare part at very low price
• bad:
  • based on LPM technology it requires 2KW every day, just to keep its battery warm (80°C)
  • moving in sleep mode to avoid the 2KW/day is complex, long and risky
  • it's a funny car, perfect to drive on the beach but not designed for long distance.

My goal is to replace the LMP battery with LIPO4 plus a BMS to define.

• first investigations published at https://github.com/Tux-Solar/emehari-bluecar
• next step is to reverse engineering BMS CAN bus

If anyone interested in collaborating please let me known

interesting.
e-mehari was one of my first options.
I think citroen has some kind of remote control to the car, and when i tried to buy one unit, it was only possible with a longterm rental agreement so i refused the idea.
