Smart Frequency-Sensing Charge Controller for Electric Vehicles

Technology available for licensing:System uses frequency-sensing charge controllers that provide automatic demand response and regulation service to the grid by reducing or turning the charging load completely off if the system frequency falls below given threshold, and turning it back on after the balance of supply and demand has been restored.

  • Minimizes the burden on the power grid and provides significant benefits to electric utilities by providing a frequency-responsive load
  • Small, inexpensive to manufacture and easy to install
