HV and LV Contactor help
Hey guys, thanks for your help so far. I still cannot figure out what I need to get to finish out the plans for this build. Any help is appreciated.
I have a custom 72V EZGO TXT with Alltrax 72500 controller. I am converting to 10 leaf Modules and using an EVMS3 with 2 10 cell BMS modules. The EVMS3 does a few things differently than the BMS16 (or whatever most of you guys have been able to use). Here are a few things I think I know: Contactors may work better than relays in my setup due to the higher voltage MZJ-400A is a cheaper alternative than the Gigavac for the same result Ian said I MUST use a 12V contactor for the EVMS3 Ian said I MUST use a 80V contactor because the high voltage will burn a 12v Single contactor is best setup, while using the Alltrax for HV and LV cutoff LV trigger on single contactor setup will keep charger from charging the pack EVMS3 must have constant 12v supply, but it goes into auto sleep mode after 5 minutes and shuts down pack power which shuts power to the DC down convertor So, I am confused. I am sure Ian said it correctly, but the way I read it I am confused if I need a 12v or 80v contactor. Also confused about the other items above. Again, thanks for your help on this |
