Successful showing of the game changing Carbon based Power Capacitors at the Battery Show 7-9 May 2019 in Stuttgart.

Kurt.Energy specialises in trustworthy clean energy system solutions.   Core building blocks are carbon based power capacitors, we call them our Blue Cell Power Capacitors. Contrary to classical lithium based batteries, these are simple to use, work from -40°C to +80°C, have lifecycles (full charge/descharge) from 10000 to 50000 cycles, no BMS needed, no thermal risk. The most cost-efficient and long-life solution on the market.

Hybrid Powercapacitors for hybrid drives

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

Stress test based on WLTP profile

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...
