Hello all!
I have purchased lithium ion batteries out of two different kinds of vehicles, and both times I had an extremely exciting find, that then turned out to just confuse me!
Both sets of batteries have an inlet and outlet port for fluids to flow through the case and cool the cells, and in both cases the cells themselves were attached to that fluid heatsink via a thermal adhesive paste. HOWEVER both actually had a thin metal plat that I was able to identify as a heating element sandwiched between the cells and the head sync!!!
I was THRILLED because up here in Michigan I had expected to need a way to keep my cells warm and this was a free little perk!. However, once I connected the two wires to my power supply set at 12v (pulled about 2 amps fyi) the heating element turned out to be directional, and sending the heat AWAY from the batteries! Crazy, right?! All I can assume is that these are designed to drain the batteries if sitting for a long time, and the thermal management system would be able to pull the heat away.
Thoughts? Ideas? Has anyone else found this in the past? Anyone have a thought of if I were to flip these pads over to then use them as true heaters for the packs?
Thanks everyone!
