Passat battery details

[Wibber]

Hi, hoping one of you can help. Any info very gratefully received, I have a battery pack from a Passat 2021 part no:3Q080484J. I bought it to run a Leaf motor but the regulations in the UK make getting on the road in a new build with a high voltage set up prohibitively expensive. So i am now looking at putting together a 48V solution. Simple question but hard to find an answer: are the battery modules in a Passat battery 48v? Don't want to dismantle it only to find that i can't use it for 48v. I know the Wiki has some details but i can't find this. As said, any help gratefully received or happy to help anyone in a similar situation if I can.

And, if the battery isn't 48v modules, anyone want a Passat battery????

Cheers, John

What will you power with your 48V battery?

Passaat modules can be broken into 12s, So 50V when fully charge + 36V when empty.

Out of interest what is it that makes registering a new build ev in the uk prohibitive?

Sorry for not replying sooner - thought the system would email when there was a response. Thanks for the Passat info. Re the cost of registering a new build: A new self-build and any significant alteration to an existing car has to pass an "IVA" test (individual vehicle approval). This is to check that it meets various roadworthiness regulations. This is just part of the accepted cost of a self build, but... if you make the car electric and it runs on more than 48V you have to get a certificated inspection of the battery. This is the same certification that a vehicle manufacturer would require for their batteries. There is only one place in the country that can certify and it seems to cost around £5,000 per battery box. So if you spread your battery modules in two boxes, you need two certifications. If you are building a Cobra this may be ok but for a small/cheap build, it puts the cost out of reach. Not sure how the kit car industry will survive once all cars have to be electric. (And, i've asked, you still have to get certification if you use a OEM battery pack unchanged)
