In theory, fuel cells are pretty simple. In practice things quickly get complicated.

To run a tiny one on your desk for a few minutes wouldn't be too challenging.

However... They produce water and can drown if you don't manage it properly. If you let them get too hot, they can dry out in places ...

I have looked at the wiki for the VW modules and they need to be arranged in a particular way that doesn't suit the way I want to configure my packs. That's why I am not using them.

Good point!

The modules are from an eGolf and are Lipos (AFAIK)

Hi Folks,

I am working on my EV conversion and I am thinking about a BMS solution.

For reasons of mechanical layout, I will have three battery packs.

I would like to have CAN output, integration with Zombieverter and low current drain when not in use as this car won't be a dialy ...

Hi I have 220 EIG Lipo pouch cells that I no longer need and so have for sale.

I bought these a few years ago to replace the failed cells in my first EV, a Citroen C1 Evie. I fitted these and a new BMS and did around 2000 miles before scrapping the car and moving on.

20 are unused, still sitting ...

Thank you everyone.

That's all very helpful

Hi Folks,

My project is slowly progressing. It has a GS450H motor and inverter with a Zombieverter to give it the magic.
I am working on the battery configuration at the moment.

I see on the wiki that I can run this from around 300v to 650v but I am curious to know what people are doing.

If you ...

Thanks for that.

I was thinking the contactor may weld shut but from what you have said and some other conversations I have had, a pyro seems like over-kill.


Thanks,

Andy.

Hi,

I am working on an EV conversion using a GS450h and Zombieverter.

I know it's very good and well used but at the back of my mind I have the worry, what if it goes Wide Open Throttle for some mystery reason?

I know dropping the contactors isn't a good idea but what about adding a pyro fuse as ...

Thank you ggter,

That's great to know.


Cheers,

Andy.

Thank you everyone.

I have gone for the Land Rover mounts and they look just the job. I am still a way from being able to test anything but so far, so good.


Cheers,

Andy.

Hi boekel,

Thanks for the offer. I could probably use about eight.
I'll PM you

Cheers,

Andy.

Hi Folks,

I am looking for PCBs from VW/Audi 4S batteries. I need the ones without the BMS on, essentially this are just connectors between the loom and the cells but in PCB form.

Does anyone have any sitting around that they would like to part with?


Thanks,

Andy.

Thank you tom91,

I have seen that thread and it has a lot info info and does imply point 2 but it doesn't say it. My unravelling of a wiring loom implies it too but I was hoping for a second opinion as I want to start putting my pack together but also because I want to add the missing info to the ...

Hi Folks,

I have an E-Golf battery pack that I have broken down to its 4S and 2S batteries and I am trying to work out the connections so I can build my own packs.
I have got so far but would like someone to check my thinking.

There are three types of batteries in this pack. Smart 4S (with BMS ...

That's great.

Thanks very much for getting back to me.

Cheers,

Andy.

Hi Folks,

Things are coming together slowly on my EV project with most of the big-ticket items either sitting on a shelf or, in a few cases, actually fitted.

The question now is one of cable sizing.

What cables are you running from your batteries to the inverter etc. and what kind of current can ...

Hmm,

Mine was due to arrive a couple of weeks ago but on the day it was due, its status changed and now Amazon say that they will tell me when it will be shipped, but they never do

Cheers,

Andy.

I've been standing in the engine bay today, taking measurements and getting my head around the task ahead.

I _think_ the Land Rover mounts will fit straight into the existing engine mounts so no chassis mods needed

I'll let you all know when they arrive.


Cheers,

Andy.

That's very helpful. It's what I had in mind and it's great to have it confirmed.


Cheers,

Andy.

Thanks both for your answers. I've got a good idea where to go now.


Thanks,

Andy.

Hi Everyone,

I have the old IC engine out of my car now and I'm contemplating how to mount the GS transmission in its place.

I don't imagine anyone hard mounts the trans to the chassis so what do you do for engine mounts.

This is for a Scimitar so it's a ladder chassis.


Thanks,

Andy.

Hi DkubusEV,

To be honest I don't. I have a pack from an E-Golf and I'm hoping Damien of evbmw gets his VAG charger working before I need mine!


Cheers,

Andy.

Hi,

Does anyone have a pair of the brass power posts required for the GS450h inverter to squirt power in past the IGBT and Coil?


Thanks,

Andy.

Yes. It's gone now.

Cheers,

Andy.
