From hotels, parking lots, airports, shopping malls to convenience stores, the preference is consistently fast chargers, which cater to every kind of customer and enable efficient EV charging while they are shopping. The sector is booming – and so are the solutions. As the technology has developed, a clear forerunner has emerged. Flywheel kinetic energy storage is changing how property owners adapt EV charging to their sites. It solves many pain points unique to property owners: cutting-edge technology makes it faster and cleaner than its counterparts, boasts long-term cost benefits, useable without grid connection, and has no need for costly upgrades.
What’s the benefit of flywheel kinetic energy storage?
Basic AC level 1 and level 2 power chargers, which come with a charge time of up to 8 hours or more, provide from 60 to 80 percent of the energy consumed by EVs. Most of this charging takes place at homes, workplaces, and via slow-charge public stations; but as property owners renovate, an opportunity for long-term cost savings comes into play.
Short EV charging times are achieved by using high power chargers that are 150 kW, 350 kW or higher. To date, fast and ultra-fast EV chargers can only be installed where enough grid power is available, near high voltage lines or a transmission grid. This creates high entrance barriers for EV access in those areas; upgrading infrastructure entails enormous cost, and a long installation process due to tedious bureaucratic approval.
To overcome these challenges, there is a real need for local energy storage and off-grid fast-charging. These storage systems must withstand multiple high-power charging and discharging cycles. The use of lithium batteries is feasible (new or second life), but multiple charging cycles shorten their already short lifespan of 2-3 years in busy locations. This leads to frequent battery replacements, making this a costly and dismally environmentally polluting solution. Comparatively, flywheel kinetic energy storage is usable for 20+ years with practically unlimited charge cycles (over 200,000) making this technology the optimal EV charging infrastructure for enabling eMobility anywhere. Flexible configuration makes it suitable for indoor or underground sites, as well as retrofit or new building projects. Efficient energy management systems absorb peak loads to prevent high demand charges, while add-on applications such as back-up power systems ensure that EV chargers are always online and ready-to-use. Battery-enabled EV charging means charging infrastructure is possible anywhere and whenever it’s needed. Property owners are no longer tied down by grid connection requirements and can even integrate renewable energy for a 100% green solution.
