2 layers here. 3 batteries in each layer.
6*4.5kwh=27kwh
Yes, that's only in the front.
Pretty tight however. The modules wouldn't fit in this config if they were 1cm longer.

Watercut. Welding battery mount.

IMG_9406.JPG First time ordering from JLC-pcb and it actually works yeyyy. Nothing fancy but it will do the job. It consist of - Teensy 4.0 - ULN2003 for driving relays and to pwm stuff. - Charge interlock. Inverter doesn't get power if charger is plugged in. - Relays for main contactors and water ...

Made a fiberglass lid for the contactors. Should look nice after gelcoat and paint.

Interesting. Have to think of a way to test drive and put some load on the cables to see if it works before cutting them into lengths then. Hopefully the fact that they are shielded makes a difference. I could probably ground them in a shorter intervals with P-clips or even wrap them into copper mes...

Contactors and precharge built on to a 12mm plastic board. Drops right onto the leaf inverter. By placing connectors and wires on the bottom of this I can make a very simple lid and keep it waterproof. Think I will make it in fiberglass or carbon.

Charge port assembly. J1772. Two 3d printed parts that presses the assembly, holding it together with 4 bolts. Thus no need to weld or drill into the car.

Amphenol SurLok Plus™ EMI connector in the making. This connects to the contactor assembly and I think it will be going in and out a couple of times. I like to build stuff that is easy to disassemble.

Shielded 35mm2 ÖLFLEX running from the trunk to the front. I am a bit concerned however that it will interfere with CAN bus wires that runs along for like 3 metres. Does anyone have any experience with this?

Yea im pretty happy with that solution. Not sure if the spline adapter will work however. I have a lathe now so I can make it a bit more balanced atleast. Shouldn't hurt=). If the transmission breaks Ill go with a coupler instead.

Time for an update=). Starting with battery. I live in Sweden. EV batteries are 50-100% more expensive here than in Norway. However due to covid restrictions I couldn't travel there for like 6 months. So that sucked. Anyway I ended up purchasing a 2021 Renault Zoe battery for a good price. 52kwh. IM...

So after a week of troubleshooting, I found the issue. Not the same I inverter/pcb with overcurrent and blown fuses that I described here a month ago. Anyway, this pcb was purchased fully assembled and tested. I had it on the bench fully working in February this year. But when test running it now it...

70v. 50Ah lithium so plenty of power. Had 350v when the problem started. Still blowing fuses now with 70v tho.

A follow up on my problem with the overcurrent and blowing fuse. I tested the igbts like you explained johu. All 6 read 0.350v-0.365v. I will be inspecting the board now. Any Ideas how to proceed?:)
Thx

Edit. Board visually good. Can’t find anything loose

Motor was 25°C and inverter 47°C. Max setting 100°C for both. I can see how a row of positive or negative igbt could be shorted to ground or positive. That would explain it. Boxster EV- I will inspect the board when dissembling it. From reading this thread and I understand that the IGBTs can get dam...

Hi, I ran into some problems with the LDU after a 2mins test driving on the street. I think we did 10kmh maximum. It has worked flawlessly on the bench with 400v. The cooling wasn't working during test drive. After the test drive car was powered off. 1min after we turned it on again but this time th...

Nice work. Is there any similarities to the chevy volt bms? It seems like it also uses the L9763. And do you have the pinout for 9pin connector on the slave board?

Ok i see. Thanks for explaining. "Proximity signal from charger" pin is actually Control pilot then.

Ive also noticed that the pinout as described on the wiki page is wrong if you follow what is written on the Sumitomo connector. This pinout should be correct for the Sumitomo connector: Pin 1 CAN H (Black) Pin 2 CHIN (Serial protocol to EV Remote wifi module) Pin 3 DC SW (enables the DC:DC converte...

Hi, Just got the dcdc working on my OBC. As I'm reading through this thread I'm seeing different suggestions about what should be connected on pin 9(charger) from EVSE. Is it Proximity pilot or Control pilot? Thx

aprx 200eu
Correction about date of manufacture its 2017 not 2015

Located in Gothenburg, Sweden

Decided to go with a Mitsubishi OBC instead so I am selling this.

Can I get 250eu?
