Hi. I’m curious, what is your setup for defogging/defrosting front windshield?

Is the size and characteristic (fast-blow? time delay?) of HV fuse known for this heater?
Max consumption I=P/Vmin=3.5kW/230VDC~15A. Mine came with the 4mm2 HV cable, which can do <25A continuously. The heater is an inductive load though.

Any chance somebody has CAN logs collected? Interested in the Thermal CAN logs. Thanks in advance.

Thanks.
In the US these heaters are found in the infamous Fisker Ocean. I can start a new topic if anybody is interested.
Connectors are the same. The wiring is mainly same. The car schematic I found doesn't show the CC/Ignition KL15 pin. I powered up this heater on my bench and it started sending ...

If I understood correctly, currently we only know to send the below to 0x2A0 (per wiki) which turns the heater on to max? Also. What is the purpose of the cc/ignition signal? Does the heater fall asleep after some time?

Does the flow direction or mounting orientation matter?

Tesla pump consumes max. 7A, Nissan Leaf pump consumes max. 3,5A? So Nissan Leaf pump can only produce ~ half the flow rate that of Tesla pump (max. 720L/h)?

Hello.
I was wondering what parameters can be adjusted to improve efficiency of the SDU and maybe squeeze more range out of the vehicle. Is it only throtramp?

I have SDU on the VW T2 - heavy vehicle with high drag coefficient - so 0...60s isn't my primary interest, range - is. I do still want to be ...

Old radiator didn’t cut it when it got 30 degrees outside recently, so I’ve upgraded to a super widescreen version.

I’ll see how it copes with just my 2 fans, but there’s space to add another at each end if it needs more blow. Actually it’s suck so the air goes the same direction when moving ...

I only need brake Regen. Connected to ESP32 web gui I do not see an option to plot values. with the other board that had wifi in the motor I was able to plot.
I tried maxregentravelhz=100 and still nothing
can you upload you parameters?

Also on the esp32 when I put the ignition ON I loose ...

Can anybody help me with a config file for Tesla SDU with brake regen that is working. I have the pin15 connected to the brake light.
I keep modifying the parameters but nothing works. I was never able to see brake regen work so far.


Per https://github.com/damienmaguire/Tesla-Front-Drive-Unit ...

put a screenshot with yours. the more ideas the better. I am going to implement the error popup on mine too. good idea.

I also want to add on the 2nd BMS, charging details. I will have to purchase the CCS board for that.

It started from the SimpBMS display and became the overall vehicle display ...

Well done!

…. I don't fancy the idea of extra T-fittings in the lines, weight of the sensors and all the brake fluidy mess if they ever need replacing. Seems easier to install electronic switch somewhere in the linkage for brake lights.

Good call. Lost my brakes already because of the inline ...

If anybody has an idea of what else should be on the main screen please let me know. There is still some space.

Would be nice is a real programmer would work on this.

Looks awesome! I use nexion display too - but a small one.
To keep it clean, for the main screen I just display ...

Does anybody have dbc files for the CAN?
I only found the following, but it’s not comprehensive.

Anyone planning to use the VW heater MUST install it upside down that is with the power sockets at the bottom as you get mini explosions due to inner airlocks inside the heater.

Should the coolant flow be reversed then too, to enter through the physically lower port and exit via the physically ...

Anybody tried uart to LIN converters to communicate with this heater?
Example..

An HOA community is perfect for the type of people who want all the expenses, responsibilities, uncertainties and liabilities of owning a home, but who miss the restrictiveness of only being a renter!

Every HOA is staffed by people who's passion in life is being a know-it-all busybody, who've now ...

I got my hands on the same heater model for cheap as well - cheap enough for the risk of not being able to successfully reverse engineer the communication. Worst case I will open the electronics and see what I can find in there. So far I am pretty confident that it is an Eberspächer Titronic CHHV ...

There is some thing strange going on, on your final module the delta across the module is the largest. Is the cable used there properly fastened?

Thank you. I'd say the connection looks good. That was my first check.
As part of this fast charging test I was aiming for 80% SOC, so this is the ...

As I continue my fast charging tests, would you say it is expected for the most positive module to be the hottest?
All in series. 1 most negative, 14 most positive.
After charging from 53% to 73%, starting at 125A, but gradually reduced to 85A by the BMS.

I found the manufacturer of the EVGo station - the infamous ABB Terra 53 and 54, side by side.
Looks like these had issues, but resolved here.

I have LIM from 2015 and the OEM i3 charging inlet socket. So all of the wires are from the inlet to the LIM plug directly ...

I fixed the issue with the time-to-charge by dividing Full_SOCt and Bulk_SOCt by 10 before sending to LIM. This is indicated by the dbc and the comments in the Zombie code, but doesn't look like is implemented in the code itself.

//Lim command 2. Used in DC mode
uint16_t V_limit=0;
//if(lim_state ...
