Re: Volvo V60 battery pack
Are you just sending the 0x1C, or together with the other commands for reading the cell voltages/temperatures ? - 0x16h (1byte, 100ms rate) requests specific slaves to report cell voltages (1Ah with incomplete pack, 1Bh when 10 modules connected) - 0X17h (1byte, 100ms rate) requests all slaves to re...

Re: Volvo V60 battery pack
Checked my notes again; it really should be the 0x01C telegram,3 bytes long, 100ms rate. - First byte: Module to balance (19,1A, 1B, 1C, 1D etc.) My note also says that 'FF' triggers all the modules to react. Original BMS-master cycles every 100ms to the next module, so the a triggered balancing wil...

Re: Tesla SDU oil pump modification for reverse operation
....One major problem I experienced was that tapping the pressure relief port, and drilling the new outlet created significant burring inside the shaft. I had to very carefully file these to allow the piston to move freely.... If you enlarge the hole with a small (3mm) carbide mill, use a spiral ty...

Re: 800V Hyundai Ioniq 5 Battery
Watch out a bit with the modern cell chemistries. I don't know if these are already NCM811, but thermal stability of low-cobalt cells is way less then your current rock-solid LGX-P1/P1.5 NCM111/NCM333 cells. The core-cell-temperature at which decomposition starts is way lower on the low-cobalt chemi...

Re: Volvo V60 battery pack
Did you found out how the ballancing works? If so can you tell me how it works. Yes, I got it working but unfortunately didn't fully document it. If I remember correctly; module addressing for balancing is in the sample code (shared earlier in this topic), arangement of cell-bits still has to be do...

Re: 1995 Golf 3 CitySTROMer with LDU and a lot of range
If you are looking for these EQA 16S modules, I currently have 6 for sale due to some change of plans. You can contact me by PM.
They have nicely integrated watercooling. Celltap-connectors included, no BMS.

Re: Anyone parting out an i3 KLE?
Have both here and just had a look; notch is unfortunately not at the right position. Also take into account that this chassis plug-in connections at the rear. Chassis of a KLE has M5 screws if I remember correctly.

Isn't it available at BMW as a sparepart ? I know the HV-chassis connector of the batterybox (330e, 530e, i3) is listed. Might be the same (watch out with the coding notches).

Re: BMW LIM based CCS2 Controller
...Open to feedback if my PWM voltage to the LIM is a stupid idea as well.... Will that work ? If I understand correctly, the LIM uses the voltage measurement to verify the pre-charge voltage on the chargerside of the contactors to prevent contactor damage. So that is with the contactors opened. Ar...

Re: GM / Chevrolet Volt Gen2 DC-DC converter
Did not check that (yet). But it's easy to check; look at the PCB and see if there is a current-limiting device between the HV-connector and the HV-capacitors.

Re: Mitsubishi Outlander PHEV heater
Received mine yesterday and immediately tried some things; - 0x398 byte0 goes 00->01 as soon as 0x285h is received. - 0x398 byte4 seems to be inlet temperature - 0x398 byte5 seems to be outlet temperature - 0x398 byte7 h70 when HV is <175Vdc, h00 when HV >175Vdc. So 175V seems to be the low-voltage ...

Re: Home built Charger from laptop PSU's
Also take into account that the most of the heavier laptop PSU's have a PE-connection on the mains for the internal mains filter. Those filters have Y-capacitors from L/N to PE for filtering purposes but that also leads to some leakage current to PE (0,5...2mA). If connecting a lot of them in parall...

Re: GM / Chevrolet Volt Gen2 DC-DC converter
Yes I connected a small battery on the output. That might probably be needed to let it start. I can't remember the PWM frequency, but I used the same as on the output (which you can measure). Given the fact that the charger uses 100Hz, I guess the DCDC also takes 100Hz. Hi i have a question again. ...

If you are new to PCB-designing, IMHO better not start with DesignSpark but use KiCad.

Re: BMW LIM based CCS2 Controller
Assuming BMW followed the datasheet of the TE contactors they will be PWM fed with a 50% dutycycle, so dissipation will be half that. But anyway, 2x6W will generate quite some heat on the PCB..bitterandreal wrote: ↑Sun Sep 26, 2021 8:32 amAre those 15 ohm resistors (R21, R22) actually capable of handling constantly 12W (~900mA @ 13.4V)?
