The product Chakratec Website

Chakratec has developed a unique kinetic energy storage technology, which enables unlimited high power charge and discharge cycles. Utilizing our proprietary Kinetic Power Booster technology, Chakratec facilitates the deployment of fast and ultra-fast EV charging stations anywhere, including locations with a weak grid.

Short EV charging times are achieved by using high power chargers (150 kW, 350 kW and more). To date, fast and ultra-fast EV chargers can only be installed where enough grid power is available (i.e. near high voltage lines – transmission grid). This leaves most roads without viable or cost-effective EV fast charging solutions, creating high entrance barriers for EV access in those areas. Upgrading infrastructure entails enormous costs, and lengthy periods of time, due to tedious bureaucratic approval and rejection processes. To overcome these challenges, there is a need to add local energy storage for grid support of fast charging.

These storage systems must withstand multiple high-power charging and discharging cycles. The use of chemical (Lithium) batteries is feasible, but multiple charging cycles shorten their life-span. This leads to frequent battery replacements, making this a costly and dismally environmentally polluting solution. As electrical vehicle sales rise, there is an urgent and intensifying need for cost-effective, sustainable, fast EV charging solutions.

Chakratec provides optimal solutions for the EV charging eco-system, circumventing the problem of insufficient power in the grid. This is done by applying the Kinetic Power Booster (KPB) based on our Kinetic Energy Storage system. Our multi-patented technology stores the electricity as kinetic energy in a fast-rotating flywheel. This technology presents two major advantages:

  • Unlimited high-power charge and discharge cycles (more than 200,000) without degradation over the full system lifetime of 20 years
  • The non-chemical flywheel is a sustainable and reusable system, as opposed to toxic and polluting chemical batteries Chakratec’s multi-cycle technology also enables high power applications including peak shaving, grid stabilization and power trading.

The solution is implemented in Vienna, Prague and Rome (Europe).
