The GWL/Modular Battery Link is a system of ready-made cabling for 12V, 24V and 48V battery packs. It consists of a set of cables and connectors.
There are three variants using 3 different connectors.
“A ticking bomb inside a living room.” This is what we can say about this installation.
The total of 800 pieces of the second hand li-ion cells from various sources
The cells joined together in to a huge battery pack
All of this mounted on a flammable wall-paper.
Please never do this!
This is a warni
The IR photo shows the frequent issue related to the pouch cells technology. The connection tabs (terminal plates) are limited in size, they will overheat very quickly when loaded with high currents.
The heat from the terminal enters the area of the whole cell and causes gradual overheating.
The demonstration of the excellent thermal performance of the prismatic LFP cells. The IR photo shows the real example and the calculated simulation of the high current discharge of the prismatic LFP cell.
The advantage of the prismatic LFP is that these cells have a massive block vol
The example of a technical solution that shows an improper handling of the LFP cells in the battery pack. The issue here is not the performance of the cells (which themselves are excellent), but the deficient thermal handling of the whole solution.
1) The first photo shows the design of a batter
Few more photos of the progress on the first of the Czech Sustainable Houses. The roof timbers are going up and soon the whole raw structure will be accomplished.
In the meantime, we are working on a small Sustainable Garden project. A Sustainable house also needs a sustainable garden. Right?
This is one of the tips related to operating the power electronics. High current switching components using magnetic coils require high peak currents.
When using low power control electronics (like Arduino boards, or the GWL/Modular CPM board) the switching components cannot
