Thank you for the photo.
I adjusted it a bit to make the opening more visible.

Great work! I have been thinking of adding a fan too, but on the wall that would match the opening in the car chassis that is behind the passenger door. I think this opening is in light beige color in the last photo you uploaded.
Have you cut a hole in the chassis? Or maybe there is already opening there that I have missed?

Thanks for the help!
I will first try to repair and then explore any additional leads.

I am looking for alternatives to fix my cracked panel.
Have any of you in Europe by any chance a roof panel?
Ideally blue in color and with opening for sunroof, but even other colors and with no opening would be fine.


First things first.
What errors do you get in the PCU? (with CHAS)
What errors do you get from the battery? (with comtool)

I am not sure how you managed to get one of these Thinks to work - both of them show minimum cell voltage 0V.

Tidlige elbiler: Think / Sv: How to repair crack on the roof
« på: ſøndag 02. Juni 2019, klokken 21:32 »
Thank you for all the advice!
I am attaching some photos.
There are 3 cracks.
It looks like I need to remove some of the rails to be able to get to the whole crack.

I am not so sure how to drill at the corners that do not have cracks without removing the sunroof arrangement - any advice?
Maybe a dremel it instead?
Also one of the crack is under a GPS antenna that is stuck with a black glue and it looks like it will break before it will give... I will try to remove it with a string tomorrow.

How do you take out the inner lining?
I can not seem to find that part in the repair manual.
There seems to be a reference to a screws for the lining in the repair manual.

I found two cracks on the roof. See attached photos.
I drilled hole to stop the crack (maybe I a bit bigger than it should have been) and am now considering how to repair the cracks. I have come up with 3 options:
 - ABS gluing - there are these ABS sticks and a heatgun at the local Hornbach
 - Marine silicone -
 - Marine 1 component polyurethane -

Ultimately I should remove the roof and re-enforce the panel from the back with a steel grid and then fill it with something... but this is really not something I have time for. So what would be the next best thing?

Am I really only delaying the need for removing the panel and fixing this properly?


I managed to log the messages from the BMS and published the preliminary results here for future reference:

I could not find a good way to easy listen to the traffic, so there will be some time before I log the messages from the charger.


Thank you!
The pictures are great!

This is as expected.
The BMS is estimating 3 (or 4) different SOC based on different things. Ah charged/discharged, voltage, ...
If you had the nikometer you would see these SOC... and when one or more of the cells in the pack report lower voltages the SOC values differ drastically.
I am attaching a photo I made on a pack with a big difference in reported voltages.
See the P: 1: and 2:... these are usually very close to each other on a balanced pack.

Thank you - don't have such card yet.
But I have a RS485 adapter that I may try to connect and see...

Made a new thread about this.
Regarding the battery pack - what is the price per kWh for LiFePO?
Why not just get a battery pack from nissan leaf and use all the electronics, contactors, heating management, etc?

I am restoring a car with a missing 12v battery holder.
I was hoping to build the bracket out of laser cut steel or reinforced acrylic plate.
So I need to build a model of it.
Any help is very appreciated!

I am attaching a composite of what looks like isometric view of the bracket.

Is there any place where I can download/access the standard used between the charger and the BMS in the Think?
I am troubleshooting a broken charger and it would make it much easier if I can isolate eventual problems.
