Ant BMS
 

I just bought 14 Nissan Leaf modules and a 7s-20s 300A Ant BMS. Is there a way to use HV and LV relays with this?
It has no internal relays for this. I plan to convert my 2011 RXV when I receive the parts and need some information.

I'm not familiar with that BMS. You need to supply more info.

It is a 10-24s actually. I bought it on Aliexpress. I couldn’t post the link. Not a member long enough?!?

Help with Cinese "Ant BMS"
 

Okay here is the information for the Ant BMS. I hope someone can give me a little more insight into this than their information does. The video link that was given me is in Chinese with no subtitles. I am trying to figure out if my 2011 RXV needs HV and LV solenoids connected and if I can even do that with this BMS. Thanks!

Re: Ant BMS
 

In your second document above, it states that: "5. Please do not short connect the two power wires, otherwise there is no low voltage automatic shutdown protection function".

I can only assume there is some sort of "set" LV shutoff in the board? It appears all power is "run thru" this BMS. Perhaps I'm wrong on this but I dunno how the thin wiring on the BMS can handle 36 or 48V when power is demanded.

Is there anything that states what the LV for the pack or the individual cell monitoring is?

It is bluetooth and there is an app for the settings. I ordered the 300 amp version. I have attached a picture of the settings page they sent in the info. Haven't received the BMS yet.

Re: Ant BMS
 

Are those just "example" settings.....or the actual settings you are going to use?

Re: Ant BMS
 

Example settings! That is a picture they sent in the info kit. I don't have any of it yet. I've seen a lot of information on here about high and low settings.

Pingeye3 uploaded a drawing for a 7 module leaf setup using an Aliexpress BMS, which is where I got the ant. It appears to be very similar. Here it is:

I will be using 14 modules instead of 7 though.

Keep in mind that design you posted only protects the pack during charge.

There is no cell low voltage protection while motoring and no cell high voltage protection during Regen on Sepex Motors.
