Re: Dala's Leaf buildthread (2015 Nissan Leaf)

I am on a roll. I'm now releasing this to the public, so anyone looking for an easy way to pair ZE0 batteries, feel free to try it out :) But read the fine print, very untested still!

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

So here's something that's good to know when testing used batteries. I recently examined the 40kWh that is soon going into a customer car, and found a small puncture in the top casing. After informing the customer, and then repairing the small puncture, it was time to pressure test the battery. So a...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

For one single card yes, but I need to guarantee that the finished product holds up for 10-15years on customer cars, along with making tens if not up to a hundred of these. So I need to get some well needed precision tools into the mix :D

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

Okay so a bit of an update on the PCB manufacturing. As you know a few posts back I posted pictures of a few PCBs that I had ordered. The original idea was to maybe assemble a few CAN-bridges by hand, and then let a local company do the rest. Turns out I have a lot to learn about PCB manufacturing a...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

I'm still waiting for some parts, but I decided to post this already since it is functional. Okay so here is a big upgrade for the Leaf. The stereo. I have the base model of the Leaf, which has a pathetic attempt at a stereo. There is a tiny display on the unit that is used for the reverse camera, m...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

Ok I promise this is the last post regarding towing, and we'll get back to something more interesting :) So lets say I "Simulated" a proper tow run with a bigger trailer. It was possible to tow for 270km with a charge stop in the middle, going max 85km/h. Any faster than that, the air resistance fro...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

I finished up the trailer wiring. It was the least fun I've had with the Leaf :D So to properly wire in the 7-pin trailer harness, I ran the cable into the boot and started to look for the light signals needed. These can be taken from the left side. - Turn signal left - Daylight running light - Brak...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

Not much has happened, still waiting on some parts for a long needed project, but I wont post about it until I have all the parts I need ;) Now for something completely different. The rear wiper was pathetic, so I inspected it. Turns out it was just about to crumble into pieces, so I replaced it wit...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

Time for some spring-cleaning! I decided to install the summer wheels and do a proper spring cleaning session. The paint has suffered the salty roads for quite some time now, so time to give it some love. Started with assessing the wheel-wells, they are surprisingly clean. Looks like my periodical w...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

My initial attempts at persuading the inverter to output more power was a failure. Check this screenshot https://i.imgur.com/ULRYJxj.png In this screenshot I added 10Nm to the demand when it went above 253Nm. So it seems like the inverter firmware clamps to some hardcoded value to keep 80kW, which i...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

How to read CAN data manually Since I need to write code that modifies some values on the bus, I thought I might give a quick crash course on how to read the data manually. Let's say you start with a log snippet that looks something like this 1 1 21163 RX 333265401 0x00000176 7 0x00 a9 05 6b 00 00 0...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

Time to deep dive into the performance aspect of the LEAF. Maybe extract some more? The energy.gov did a good test on the standard Leaf drivetrain. It can be viewed here: https://www.energy.gov/sites/prod/files/2014/03/f13/ape006_burress_2013_o.pdf They checked the output, efficiencies and temperatu...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

So since the Muxsan CAN bridges were sold out, and I'm going thru quite a lot of them quickly, I decided to try and build some on my own. They are open source after all :) I ordered a few PCBs from JLCPB. I opted for the more expensive lead-free version. And ofcourse in white, love white PCBs :D htt...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

Another minor maintenance thing, I figured it was a good idea to replace the cabin air filter. I picked this up a few weeks ago too, it was the cheapest filter available. I'm not to bothered about the charcoal ones, since I do most driving on open roads, so not a lot of smog to filter. And the elect...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

Yeah let's get back to battery stuff :D I made another thing open source. I've been approached by a few who have done bruteforce upgrades. Last year I experimented with the 30kWh cells inside a 24kWh battery, with mixed results. As you know, this method of upgrading has been superseded by the clean ...
