Main contactor:
Here's the chademo contactor:
So we got to work a step further by loosing the packs.
disconnected the wires for the cell-BMS-boards
And prepared the cells for removal from the frame:
We found how attaching a solid piece of steel at the outer end of the 5xLEV50-8 we would have all of the 5 packs fixed at both ends. This due to the LEV50-8 packs already being fixed together on the side towards the center of the frame. Sure lifting 75kg of batteries (5xLEV50-8) is unhandy however having a piece tying them together could work in keeping the cells in place and reuse the buss bars. Just taking the cells out of the plastic bay and out of the securing fixing points of the bay causes the LEV50-8 cells to twist and breaks the buss bars if lifted up all together. We put a piece of wood below as additional support in preparation for removing them from the battery frame.
Taking a look at where best to connect the HV wiring on the car as considering a solution via the chademo inlet.
I took out the plastic cover surrounding the wheel below the chademo inlet.
The brown'ish colour covering the ducting and others will be rust-protection.
So I am looking for options of how to tap in on the Chademo HV wires. Looking to where there could be space to fit the contactor and HV wires coming from the 2nd pack.
To get more space I took out the inlet:
And checked for any space on the inlet to fit a second set of HV wires for the 2nd pack.
Obviously no extra space on the inlet terminals.
Next I took a look behind the inlet area looking for space of where to fit a junction of the HV wires.

From this I'm seeing space behind the inlet if wanting to place the contactor or some kind of junction of the HV wires.
I took out the chademo inlet by loosing the clips using a flat screwdriver.
Next I worked on recovering wires from the wreck.
I want to reuse the HV wires and BMS wires. Regarding the BMS wiring I could use the electrical diagram over the circuits of which wires does what.
This will be the BMS and wiring on the wreck. I removed the A/C controller at the bottom to get a better overview.
I've made an understanding how the right-hand yellow connector on the BMS is connecting the battery sensors. Anybody who can bring clarity to this? .. wiring diagram would be helpful.
On the left-hand yellow connector it seams there are a bunch of other stuff connected. I'm wondering what each of these wires do and which are needed for the BMS to keep balancing the battery pack. The intend is to have the 2nd BMS continuously balance the 2nd battery, without communicating to the ECU, unless the left-hand yellow connector is taken out of the 1st BMS and inserted into the 2nd BMS. Anybody who can clarify as to whether the left-hand yellow connector can be left out and still having a functional BMS?
Without the wiring diagram I followed up the wires from the left-hand yellow connector to figure out where they are going
Blue and Grey are routed to the front of the car. The white seams routed directly to the ECU. The others looks less clear as they go in to those junction-connectors near the A/C controller.
Input and comments are welcome.. and a wiring diagram. 
This progress was made over 3 days. After a full day mostly underneath the car I got the BMS & ECU wires and connectors off.. Had to cut most of the ties to release the wires and to keep all the wires in one piece which was the aim. I also got the HV wires from the battery off as well.
So next up is
- Clarity on BMS wires: What does the wires of the left connector do?
- Clarity on HV wires from 2nd battery via Chademo HV wires. How and Where?
To be continued..
