VW Passat B4 EV Conversion Project

Hey everyone! New here. Finally, I’m converting my VW Passat B4 to electric power and wanted to share my results.

Main components

  • Battery pack - NMC ~40kWh
  • An asynchronous motor with the copper rotor
  • Curtis 1238 controller 84V 550A
  • Flatpack2 charger
  • BMS A1109+A11039G2

Progress summary

For someone who wasn’t following along on my YouTube channel, I’ll quickly sum-up my progress to date:

  • Oct. 9, 2020: Power steering is working
  • Oct. 30, 2020: The motor is installed and working
  • Nov. 13, 2020: Heater and air conditioner installed
  • Apr. 18, 2021: First Test Drive

Plans for the future

Going forward, my plan is to ensure stability and operability of all standard vehicle systems like power steering, power assisted brakes, air conditioning, ABS, etc.

Here’s my first test drive video:

Quite a project. Hope it is fun!

Oh, It’s really fun, I’m learning a lot by doing it. And the results are quite encouraging. Recently took a road trip, went to visit my parents. Got excellent results: 240 km on 40kWh test battery. I was riding at an approximate speed of 70 km/h. My goal is to get 300 km on a single charge out of this beauty.
