Have you ever burnt the dish on the stove?GWL Team has just begun the New Year with a similar experiencecaused by an improper cell operation.
As a result of a human operator failure and as a result of an improper setting of the charging machine,GWL team has just experience a thermal runaway for a 10
Question: I saw that some LFP cells allow the operation up to 65°C or even more. Do you have any suggestions for a high temperature operation?
Answer:The GWL team stronglydiscourage the continued use of the LFP cells in temperatures above +50°C.
Even though some datasheets ma
What color is the plus pole? , the PLUS pole is marked by RED color and the MINUS by the BLUE color.
However, in Asia, sometimes there is a reversed color coding, wherePLUS is marked by the black colorandMINUS by the red color.
FAQ: I need to get the exact measurements of the cell to design our own battery box. Please send be the drawing.
1) Yes, of cause, the best idea isto get the samples of the cellsto make a small demonstration installation and design the size of your solution based on the real prod
Check the Test Report for the ELERIX EX-T30K LTO cells that shows the performance of the cells at +25°C and also and -25°C.
This test confirms the excellent energy storage capacity for the LTO cells even in the low temperature conditions.
The results show that even under -25°C the LTO cell pro
Question:I have a battery pack installed in my EV (in my boat, in my RV, in my house, etc.) I wish to check the condition of this pack to see the real capacity of the cells. Can GWL offer any solution for me? (Perhaps you can come to me for the weekend and make the test. Or you can send m
The winter of 2022-2023 is coming in just a few months and many customers wonder aboutthe performance of their battery packs. Especially those who have been using the lead-acid batteries.
The performance of the lead-acid batteries drops significantly in sub-zero temperatures.The above diagr
Question:Concerning the LTO cells, I can see that some information mentions the nominal voltage at 2.3V some other datasheets say 2.4V. I wonder what is the nominal voltage of the 5-cell pack: 11.5V or 12V?
Answer: both versions of the information are correct. The reason is that the disc
Comparingthe permissible current rating for copper wires, it is evident that the US standard – known as the AWG - American Wire Gauge (or Sizes) – allows for higher currents than the European standards, expressed by the German VDA norm.
For example, a50 mm2 cablecan carry some
The GWL Team is able to make a solution for any type of energy storage. The copy of the drawing shows details of a project processed by GWL. Large energy storage cabinets with up to130 kWh battery packs and 50 kW – 400V 3 Phase input/output.
