Re: ID.3 and other MEB battery packs in conversions

Jochen, what a bummer, sad, but think you blew the smd resistor in the line of the flex cable, leading to cell 12, disabling it effectively. 100mA is about max what it will take...

Re: 64kwh Kona battery

MAX17843 is cracked by Bexander. I made an interface board for it successfully communicating with the latest Renault Zoe, Peugeot e-208 and Kia Niro PHEV. Let me know if you want one to try. Quite possible that MAX17845 is similar enough to MAX17843 so it can be controlled with MAX17841B. A first st...

Re: Mitsubishi outlander charger and DC:DC

Hi. Which side of the contactors have you guys connected the HV to? Any significent current draw that makes it "dangerous" to connect directly to HV battery? Thx.

Re: Renault Zoe/Leaf PTC heater

Ran 4mA across the HVIL. Required 2.5V which seems resonable. Made no difference. Maybe it needs a combo of that and a signal generated from a master as you describe Johu. I doubt it however.
Here is the code I have been testing with.

Re: Renault Zoe/Leaf PTC heater

Interesting. Worth a try. Measured between HV neg and one of the HVIL cables and got 12kohm. Doesn't make a low current chain improbable if its isolated I guess.

Renault Zoe/Leaf PTC heater

So for my e46 build my plan was to use a gasoline Webasto heater. However I managed to squeeze in allot bigger battery than what was first planned which meant that the reduced range by electric heating would have a smaller impact on usability. l288884a.jpg Purchased a PTC heater from a 2015 renault ...

Re: BMW E46 320d Japanization

Rolled the dice and purchased a passat gte brake servo. Essentially a Tesla Gen 1 booster. And it actually seems to fit on the e46 when flipped 90° to the right wohoo :P The E46 master cylinder also kind of fits on the ibooster body. Even has the same bolt pattern as the passat one so I will try to ...

Re: BMW E46 320d Japanization

Update time. Finally sort of finished the front battery thus making room in the garage for the car. Rather nicer to work on the car in 15°C vs -5 :D . The rivets need to be waterproofed and I think I will make an extra support under the battery. tempImagebIUXjN.gif tempImageuLxFYX.gif tempImageT1tsG...

Here I'm TIG welding the box. Was just as hard as I expected to be. Should be strong enough but not waterproof. Therefore I'm thinking of adding something along the weld to seal it. JB weld or butyl seal tape.

2 layers here. 3 batteries in each layer.

Yes, that's only in the front.
Pretty tight however. The modules wouldn't fit in this config if they were 1cm longer.

Re: BMW E46 320d Japanization

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.

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.
