48volt club car limthium battery exploded
 

Thought I would share my experience last night with you guys. So I did a lithium battery swap from ev battery center in my 2008 club car predecent golf cart about 2 years ago, (I would have been 12 at the time), I installed a big sound system on it with a sub, underglow, a lift kit, ect. Here’s what happened last night. I threw the battery on the charger when I came home from school aprox 4pm whaile I was installing a new tow/run switch, dash, tires, and a steering wheel cover. May I remind you that the battery was fully disconnected from the cart via the Anderson connector. After installing these I went inside and came back out to check the battery voltage at aprox 7 pm. As soon as I opened the door to the garage I smelled a funny smell, I went over to the battery and noticed it was bubbling a bit and leaking a fluid, knowing these battery’s can explode I quickly disconnected the charger and immediately pushed it out of the garage. I went to grab a fire extinguisher just in case and sure enough, when I came back out it was up I’m flames exploding like a fire work. I called the fire department and grabbed a hose and 4 fire extinguishers and immediately went to work, but that did nothing to put out the fire. Thank god we were able to get it out of the garage or the house would have burned down. I will attach a few pictures and videos of the event, the golf cart burnt to the ground. Hard to watch my whole childhood burn to the ground in front of me. Also a bummer I just installed a bunch of new parts on it literally the same day. I plan to upload the security tape footage to YouTube

First and foremost. Glad you and your house are safe! That is definitely a heart breaking experience, as well as scary!

I don't mean to seem heartless, but I think we are all wondering how this happened. So I am going to ask:

I did a quick look at your previous threads and see you got a Nissan Leaf battery pack "system" from evbattery.

Is it possible there was physical damage to the battery?
What charger were you using?
Were you using a BMS?
What LV/HV shutoffs were you using? Relays or contactor?

Again, glad you're ok!

So was the battery charging disconnected from the cart?

What kind of BMS with cell level protection and charger disconnect circuit was being used?

Was there a temp sensor installed in the BMS?

Does the BMS control the charging current or just voltage?

I always try to build in more than the minimum redundancy safeties when working with lithium cells, lots of energy in those cells.

Wow, glad everyone is safe. You are going to be bombarded with questions as you might imagine, we are quite curious as to the details. I guess my first is, What voltage were these being charged to? We’re you taking them to the full 4.2v per cell? Once again, glad you and your family are ok.

the battery was from ev battery center and I bought it fully assembled with a wifi bms installed in it, not really sure how it happened I guess there was a malfunction in the bms system, I was in touch with nick back before he passed, and we worked out my previous battery situation and he told me there wasn't any damage done to my battery, but I guess there was

I was charging it though the bms with the charger I got from ev battery center

Re: 48volt club car limthium battery exploded
 

Well, one more time..glad you are safe. I guess let the speculations begin.

Subscribed. Scary. Now concerned about my conversion, which I haven't even really started other than ordering the batteries.

Re: 48volt club car limthium battery exploded
 

Glad you're safe.

I'm a little confused from your original post. You said you disconnected the battery then charged it? What parameters did you have the BMS set to, ie LV and HV disconnects???

What kind of problem did you originally have with the pack that Nick helped you through and how long ago was that?
