I'm converting my trusty VW Passat B4 to EV and wanted to share my progress with you.
I bought this car a long time ago and quickly fell in love with this workhorse. I covered quite some miles with this car and realized that it has a soul.
This isn't my first EV conversion project, some years ago I converted ZAZ-1103 to electric power. The project was fun, learned a lot while making it.
Another EV conversion project that we did quite some time ago was a Ukrainian Niva conversion, which turned out really great, the owner liked the result.

This time, besides transition to electric power, my goal here is to keep all car systems in working condition. Starting from the power steering, power-assisted brakes, air conditioner and so on...

Why Passat?
You may ask "Why Passat"?
Firstly, everything in this car is really well done. It has a quite advanced configuration for its years. Air conditioner, heated seats, airbags, ABS, it has practically everything you need.
At the same time, this car is quite simple. It doesn't have a central computer, so it'll be relatively easy to make all these systems work.
Of course, there will be some challenges, but nothing too complicated.

Main components
  • Battery pack - 2P26S, 200Ah NMC ~20kWh
  • 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

So, 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.
I'll keep you all posted with my progress.

Here's my first test drive video:

Took a road trip a couple of days ago, went to visit my parents. Got encouraging results: 240 km on 40kWh test battery. I was riding at an approximate speed of 70 km/h. A utility trailer loaded with a weight of 100 kg takes approximately 25% of the available mileage. Looks like my goal of 320 km on a single charge is not as far away as I expected!
