Re: Please help with wiring diagrams for Zeva BMS and Leaf
Thanks. Yeh I figure he’s prolly really busy. Seems like a good guy for sure and very helpful. I was just hoping someone may have a copy since I have been unable to get it from him. I’m sure he’ll get back with me when he gets a chance, just checking for an alternative solution. Thx

Re: Please help with wiring diagrams for Zeva BMS and Leaf
Thanks again Gary. I am electronically challenged so it took me awhile to makes sense of this even with the great plans. But, I do have a question for you and/or Sergio. He had mentioned you using a sleep switch and gigavic contactor. (edit: as I recall, he mentioned that). But, I don't see either on your plans. I almost have it all figured out how to wire this up for drop in for my cart. But I need some 10 and 18 gauge wire and Anderson Connector. Also, need to figure if I am using a LV or HV relay, or using a single Gigavic Contactor (per Sergio suggestion), and a sleep switch.
Also, if you don't mind, can you suggest a size for the 84v to 12v convertor I would need? (i.e. 180w 15a or more or less?) Right now I have a separate 12v accessory battery with a separate on board charger for it. But, it may be cleaner to do it like your plans show. Thanks |

Re: Please help with wiring diagrams for Zeva BMS and Leaf
Thanks! I did see that thread and have that section printed out. I didn't realize he used the Gigavic Contactor. I will look into it further and see what I can find out.
Do you need the Anderson connector if you use the Gigavic contactor? Sorry, just learning some new terminology here and felt like the Anderson deal was for a quick disconnect. |

Re: Please help with wiring diagrams for Zeva BMS and Leaf
I see that the schematic for the sleep switch and Gigavac is on the 16 cell BMS. I have the EVMS3 with two 12 cell modules. They don't have a sleep option, nor does the EVMS3. I do see that they ran the anderson connector right in front of the Gigavac, so I answered that. But, still confused on the proper set up since Sergio recommended the Sleep switch and the Gigavac but I don't see how to include those.

Join terminal to ground/chassis momentarily to wake the EVMS from sleep mode (without entering Running or Charging mode). Note: Other MPI functions will still perform an EVMS wake up too Didn't see anything in the EVMS3 12 cell manual about a sleep mode. Might be worth an email to Ian at Zeva to see if there is a reason they don't include the option. |

Re: wiring diagrams for Zeva BMS and Leaf
Thanks for the info! I will get with Ian and ask about the sleep mode. I suppose I will order the Gigavac GV240 from him (??). Is that what you used? You just hook it up in line from the main pack to the main solenoid before the controller? Did you install a fuse between the gigavac and controller? How big? I'll have up to 83v through it. Thanks!

Well I'll have to go through my documentation to know for sure which Gigavac contactor I got and size of fuse. However, you may need different since you are doing a higher voltage setup. I frankly do not have the knowledge to be able to answer that for you. Maybe that's another question Ian can answer for you. Or possibly Sergio, Pingeye3 or some other guru on here. I can say I ended up ordering my Gigavac contactor directly from Gigavac on their website. It was a little less expensive doing it that way, as opposed to ordering it from Zeva. |
