Mitigating the Impact of EVs on the Grid


Patent Granted for Technology to Protect Grid from Instability, Stress and Cyber Attacks

As the popularity of electric cars grows, there are concerns that an increase in connections between electric cars and the power grid could destabilize the grid and make it vulnerable.

Nation-E, an energy information and communication technology company, has been granted a patent by the Israeli Patent Office for their technology that ensures the stability of the electric grid in the face of increased connectivity from electric cars. Israel is the third country to approve such a patent for Nation-E, along with Germany and China, with a patent is pending in the United States as well.

The patent recognizes Nation-E’s technology’s ability to serve as a security layer protecting the grid from instability, stress and potential cyber infringements caused by connecting electrical vehicles.

“With the growing share of plug-in hybrid cars and electric cars and the roll out of smart metering and smart grids, new challenges need to be addressed” said Nation-E’s president and founder, Daniel Jammer. “From an energy cyber-security perspective, an electric car is part of the Internet of Things, and so is equivalent to an end device in an IT network. The same challenges facing an IT network face the energy grid.”

The patented solution serves as an alternative for grid-connected charging posts and can function as a mobile or static fast charging station for end devices. Embedding Nation-E’s propriety Bank of Energy software comprised of big-data analytics and energy cyber-security applications and methodologies, the system serves as an energy buffer protecting the grid in case of infringement by taking various pre-emptive actions, including energy islanding.

Rami Efrati, the former Head of the Civilian Sector Division of the Israel National Cyber Bureau in Israel’s Prime Minister’s Office stated: “Nation-E’s cutting-edge solutions tackle a major challenge that smart grid and critical infrastructure security are facing. One cannot underestimate the gravity of a successful attack on the energy grid and the need to eliminate any potential breaches.”
