Kinetic Energy Storage Technology | INTERVIEW with Chakratec

Founded in 2013, Chakratec is a privately held company that has developed a unique kinetic energy storage technology, which enables unlimited high power charge and discharge cycles. The Israel-based company offers kinetic power boosters, high power chargers and fully managed charging services for electric vehicles (EVs), deployed in Austria, Italy, and the Czech Republic, with leading energy and automotive companies. Chakratec’s vision is to enable high penetration of renewable energy by providing economic and environmental electricity storage solutions.

Chakratec was a Finalist for the 2019 ees AWARD. We talked to Mr. Ilan Ben-David, Chakratec's Co-founder & CEO.

ees International: Thank you very much for this interview! This is supposed to be the year of energy storage and e-vehicles as main transportation means are increasingly a real scenario. Range and charging, both the number of charge points and the time it takes to recharge the vehicle, seem to be the main challenges for the proceeding. Chakratec offers an innovative solution with kinetic energy storage technology. How does the system work?  

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.

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.

ees International: Lithium-ion batteries are currently the most-used rechargeable storage technology  used for charging points. What is the difference of the kinetic storage technology to lithium-ion batteries?

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.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.

•            Cost per cycle significantly lower than chemical based systems

ees International:  More EVs need more EV charging stations and that strains the public power grid. How do fast-charging and power boosts go together with strained power grids?  

Energy storage systems  have a large social and economical benefits in the EV charging business: Reduces charging times and lowers customer “range anxiety”’ Improves grid stability. Defers infrastructural upgrades to the utility, Improved business case for EV owners and CPO., Reduces demand charges incurred by the customer, Reduces the carbon footprint of the charging station.

Basically the energy storage systems acts as a power booster to enable the fast charging session and as a buffer and load management system to the local power grid.

ees International: With EVs replacing all combustion motors and parking lots full of EVs that need to be charged, what will the future hold, what is your vision when it comes to scale of the kinetic storage technology?

As the number of EV’s rise, more and more chargers and charging solutions will be needed. At some point, infrastructure upgrade will become a barrier for deployment, leaving areas with no viable solution. The use of energy storage systems will become more and more urgent. We believe that the major economical and environmental advantages of our technology can make our Kinetic Power Booster a go-to solution for every charge point operator.  

ees International: Last year, you were one of the finalists for the ees AWARD with the Kinetic Power Booster (KBP), especially designed for high-speed charging. How has the product evolved since then?

Since last year we had some significant progress. We have active deployments in Austria, Italy, Germany and the Czech Republic with leading energy and automotive companies. We partnered with Blink Charging, the second largest charging network in the USA to bring our technology to the US market.

Technology wise, our product line is evolving together with the market. Our next product in line which will be available later this year has almost double the power and capacity, in the same volume. We are also working on the next gen flywheel which will be even more powerful.  

ees International: Chakratec will be exhibiting at Power2Drive, also part of “The smarter E Europe” fair in Munich, June 17-19 2020. What are you looking forward to? 

We love these industry events. We are looking forward to meeting new and old business partners, learn about their needs and introduce our technology. It is always fascinating to see how the market is growing and evolving. We hope that the CoVid19 crisis will pass and allow our industry to keep charging forward.   

Thank you very much for the interview, Mr. Ilan Ben-David!
