Re: [RE-wrenches] Home grid stacked battery heating

Wrenches
I have also used the turtle heater and it's just enough to keep everything
up and operating. Insulation and a warm thermal mass makes it all hold
together

Re: [RE-wrenches] Home grid stacked battery heating

[Allan Sindelar via RE-wrenches]

I did this modification to a 16kW Blue Ion LiFP bank during installation, following this guide, Darryl. Blue Planet had sent me this. Shortly after initial installation a plumber had installed an electric space heater in an unheated space with water pipes, which of course soon drained the batteries to LVD, so the BMS had shut them down. The BMS won’t accept a charge until the batteries were about 1 1/2 degrees F above freezing. I did a winter service call and worked with BP tech support. I plugged the same space heater into a portable gennie and pointed it to the batteries, and as soon as the BMS registered above freezing it allowed recharge from the array. As I recall, besides the bubble/Mylar insulation (which was surprisingly easy to install) the system used an 18w terrarium heating pad in the bottom shelf under the batteries and a 9w pad on the upper shelf, controlled by an external freeze-prevention thermostat. With a sufficient whole-house array it’s proven to be a negligible load. It’s a standalone system. I don’t recall the low-temperature discharge limit; it’s quite a bit lower than the minimum charge temperature. And summer heating is irrelevant with the thermostat. The rest you can get from Blue Planet. AllanOn Nov 5, 2023, at 2:03 PM, Darryl Thayer via RE-wrenches  wrote:Great site, Allan, but many facts still need to be included.  Was there a discharge or charge going on?

Re: [RE-wrenches] Home grid stacked battery heating

[Kirk Bailey via RE-wrenches]

Something else to consider is that many of the modern LFP batteries use a
relatively large amount of power just to keep the internal BMS/contactor(s)
energized, independent of whether the battery is being charged/discharged.
For example, I believe the Fortress eFlex 5.4's use on the order of 12-20 W
continuously, *each*.  A stack of four generates a significant amount of
heat from this alone!

Cheers,

Kirk Bailey

Re: [RE-wrenches] Home grid stacked battery heating

[Darryl Thayer via RE-wrenches]

Great site, Allan, but many facts still need to be included.  Was there a
discharge or charge going on? How much power was being drawn by the
heaters?  If this is for a standalone system, energy consumption is very
important. What is the lower temperature cell discharge limit of Blue
Planet?   What concern was taken for the summer and overheating?   What are
the blue planet-specific heat and weight of the batteries?  More questions,
but I doubt if anyone else is interested. Thank you.

I know the new SolArk high voltage outdoor batteries have a built in heat
pump (as well as a fire suppression system) Above and beyond that, I
haven't heard of any workable solutions.

[RE-wrenches] Home grid stacked battery heating

[Dana Orzel via RE-wrenches]

I know we have had this run thru before & wanted to see if any new options
for heating LI batteries.

 

I have an 8 pack of Homegrid LI batteries that is off grid with Radian
8048a. Originally, they were not going to be there for the winter, now it is
a possibility they may visit. Plenty of solar 6KW+, hopefully generator back
up waiting on delivery currently.

Currently located in main room high ceilings/log cabin.

Looking at creating an insulated closet & using terrarium heaters controlled
if over 51volt heater on AC from inverter. Or just boxing in with 3-4" of
blue board Styrofoam..

 

Has anyone else done something similar?

Has anyone done this & it did not work?

 

Thought & suggestions...
