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

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...

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.

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.

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...

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.

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...

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. ...

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..
