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.
The DC/AC part is based on theVictron
The photos are showing the read-to-go steps ofthe abuse by the axe-hammer in the hands of the fire-fighter.
The cell had to be hit several times to produce any significant effect. As seen from the reading of the IR camera, the temperature ofthe hot area has reached some 108°C.&
In the spring of 2019, the GWL/Team has organizedthe lithium cells abuse demonstrationto verify the performance in real conditions. There were following goals of these tests:
The answer is simple: yes, but it is not easy.The LFP lithium battery is made of materials that are flammable and it will burn, if overheated.
The photos showthe process of fire on a prismatic lithium battery. The battery was fully charged and then set to fire by a flame-thrower. As you can
GWL has been working on the introduction of the new range of the high power LFP cells under the ELERIX brand. Part of the testing isthe verification of the thermal performance for the cells.
This photo set shows the results of the high current over charge testing.The cells is discharged with 210Amp cu
The series of photos shows the progress of the short circuit test for the LTO-40Ah cell. At the beginning of the test, the temperature of the cells is same as the temperature of the surrounding, so that the cell is not visible at the IR photo.
Starting the tests, the temperature begins increasin
The data recorded at the short circuit test show that the maximal temperature of the Lithium Titanium Oxide - LTO-40AH - cell reached to some 94°C.
This tests proves that the lithium titanite(LTO) batteries are very safe and even during a massive short circuit,the temperature stays within the
The data recorded at the short circuit test show that the maximal temperature of the Lithium Iron Phosphate- TSWB 40AH - cell reached to some 85°C.
The outer temperature of the case measured by a temperature sensor was above 60°C, the more detailed measurement by the IR camera reached 8
The diagram on the left shows the data from a direct short circuit of the TSWB Winston 40AH cell. The cell was fully charged (even a little bit overcharged) to 3.4V volts of open voltage at the very beginning.
Right at the start, the current reachedthe peak above 2200 Amps. As the voltage of the cell
In April 2019, GWL Team has made extensive tests of various lithium cells to demonstrate the results of abuse and damage for these cells.
One part of the test was adirect short circuit dischargeof a fully charged TSWB Winston 40AH cell.
The photos show the preparation of the test.
