Re: [RE-wrenches] Exploding LFP battery

[Jeff Clearwater]

Actually thinking of my last post - pretty unlikely the heater being on 
would coincide exactly with opening a battery that had gone to 5 V.


But It strikes me that Relion would really want to get to the bottom of 
this - especially if they thought this story might spread and hurt their 
reputation - not to mention just ethical followup on a safety hazard!


So If it were me I'd call Relion and let them know we (the Wrenches 
List) really wants to know what happened and their reputation is in 
question.  The fact they manufactured it - they are the ones to do the 
forensics on what happened - by analyzing the cells and conductors in a 
safe lab environment they can probably trace back where the 
short/overcurrent occured.


Best,

Jeff C.


Hey Jay,

So at the 4:35 mark of this quick review of available LFP batteries on 
the market at the time (2019) - Will Prowess states that "they 
(Relion) are the only battery that has a built-in battery heater (I 
think he was implying as standard equipment and not an option).


Is it possible the battery heater circuit stuck on?

I thought of a few more ways this could have happened. The installer 
over torqued the battery terminals. There was not SPD protection in 
the system and it got zapped and escalated. Working on SPD's now for a 
guy. He does not see the value and knows everything!  Pretty hot out 
here in the West!  5PM !  Take care! Cheers!

HI All,

The cover never got all the way off before it was blown off, it was 
just started to be opened, so no way there was an external ignition 
source.  If it was an explosion it was all from internal components 
except for possibly some O2 coming from the outside.


My other question still hasn’t been answered.
If the BMS isn’t taking care of over/under voltage and over current 
what is it doing to prevent damage to the battery?
( this system was within the input PV or output inverter watts/amps of 
the battery specifications) And I just found out that on the day of 
failure, no one has been living there for months and only a grundfos 
SQFlex and a few lights were on, no big loads.


Now maybe I’ve been under the false understanding that this is the 
primary job of the BMS?
Yes I know that there is also cell balancing, % monitoring, blue 
tooth, wifi etc that can be included in the BMS but to me thats all 
secondary.


Hopefully someone can clear this up for me.

My .02 on this, and just a guess, the open loop charging parameters 
were not set right or charge limits for the battery were too high. The 
other way to kill LFP is large loads exceeding the battery max 
discharge current.


Closing the loop eliminates just about all of those issues. It brings 
the battery into the safety area of LA batteries that are still hard 
to beat offgrid. I am not saying you can't blow the top off a LA 
battery eitherWink

Hey Jay,

So I don't believe ReLion batteries are openable - so it's most
likely that when he decided to open it he cut into it and shorted the
leads.

As for recycling - first is health safety! I'd suggest he contact
the manufacturer and get specific instructions for safing the mess. Will
Prowess of DIY Solar Youtube channel had some leaky cells and the
manufacturer sent specific instructions to contain and ship back the unit.
You could contact him and he might know but the manufacturer might know
better for that specific model.

Hope that helps!

Very few
details...What does it mean "he opened it up" I would even know how to do
that with the L-ions I've been around, seems like its something a
manufacturer should be doing. Temperature? charge rate? recent usage
history? Age? Was it disconnected? Did contacts touch a conductor?


  You can probably get water to explode if you abuse it just right.

Re: [RE-wrenches] Exploding LFP battery

[Steve Higgins]

I have to agree... the gasses that come out of these cells can still be
flammable...  My guess is the settings were too high, or a cell or two were
already in thermal runaway,  causing internal gassing.  When the cover was
pulled off that gas found an Ignition source and ignited.

Inverter and charge controllers all have relays in them and every time they
switch you can ignite flammable gasses if the concentration is enough.

This is why it's always very important to make sure the room that any
battery is installed in is properly ventilated, especially when you are
working in said room.

Re: [RE-wrenches] Exploding LFP battery

[Dave Angelini Offgrid Solar]

My .02 on this, and just a guess, the open loop charging parameters were
not set right or charge limits for the battery were too high. The other way
to kill LFP is large loads exceeding the battery max discharge current.


Closing the loop eliminates just about all of those issues. It brings the
battery into the safety area of LA batteries that are still hard to beat
offgrid. I am not saying you can't blow the top off a LA battery either

Very few

that with the L-ions I've been around, seems like its something a
manufacturer should be doing. Temperature? charge rate? recent usage
history? Age? Was it disconnected? Did contacts touch a conductor?


  You can probably get water to explode if you abuse it just right.

Re: [RE-wrenches] Exploding LFP battery

[la...@starlightsolar.com]

Damaged Li battery safety, For information only.
Our procedure to decommission any suspect failed LFP cell is to apply small 
load (<0.05C) until all electrochemical energy is removed. This should 
preferably be done in a safe area outside. After full discharge, physically 
damage the cell terminals so it can not find it’s way back into service. 

No stored energy the battery means you just have a container with various 
elements like Aluminum, copper, lithium, graphite and so forth. See MSDS your 
battery. Unfortunately, carriers still consider this a Li battery and apply UN 
hazmat shipping rules. For now, we are storing cells until recycling is cost 
effective for us.

Re: [RE-wrenches] Exploding LFP battery

[Dave Angelini Offgrid Solar]

I sill have a few blown 200A fuses from the LG RESU10 48 v test here.
They look nasty BTW. Not just open but blown open! How were the rest of the
batteries Jay? Curious how they were charged as that is usually the killer.
Too much solar or a big charger over 100 ADC?

 When we recycle, LFP still
goes to the Waste Management commercial site. Guard gates and looks like a
prison
from the highway near Kettleman City. A real in the middle of
nowhere town. I would like any info on recycling. I do not think there is
much that is reliable or responsible. It was bad before C19 and I do not
see much going on in California. EPA is useless for this in my
experience.

These folks below will only take 300+ pounds of lithium ion.
Anybody used
them?

Re: [RE-wrenches] Exploding LFP battery

[Jeff Clearwater]

Hey Jay,

So I don't believe ReLion batteries are openable - so it's most likely 
that when he decided to open it he cut into it and shorted the leads.


As for recycling - first is health safety!  I'd suggest he contact the 
manufacturer and get specific instructions for safing the mess.  Will 
Prowess of DIY Solar Youtube channel had some leaky cells and the 
manufacturer sent specific instructions to contain and ship back the 
unit.  You could contact him and he might know but the manufacturer 
might know better for that specific model.


Hope that helps!

Very few details...What does it mean "he opened it up"  I would even 
know how to do that with the L-ions I've been around, seems like its 
something a manufacturer should be doing.  Temperature? charge rate? 
recent usage history? Age? Was it disconnected? Did contacts touch a 
conductor?


            You can probably get water to explode if you abuse it just 
right.
