How robust are blue cell power capacitors? This you know only when you test beyond the specifications of the datasheet. While the full test report is being prepared, hereby a few early test resulst of last week. First we test some 18500 and a some 18650 cells by...

How can hybrid power capacitors be used best and improve on lithium-in batteries? Why is power density a competitve advantage? How can it save weight and hence reduce the energy consumption? Read the full article here: Hybrid powercaps and hybrid drives

New stress test with carbon based power capacitor. This time we simulate the WLTP driving profile by loading a cell at 0.5C, 1.0C, 5.0C, 10.0C (1C = 1.3 Ah). Average load: 3C. Things to notice: the cell charges to 75% at 5C in 10 minutes, the cell completes 3 test...

Last month we completed new stress tests on the power capacitor cells at the test facilities of Flanders Make. Here's one of the results you can find in the full report. An 18650 cell (2,7V / 1.3 Ah) is fully charged at 10C (13 A at 2,75V) and then discharged with...
