What began as a pilot program for the Sacramento Municipal Utility District (SMUD) in California is now becoming a mainstream solution for managing the power to its electric vehicle supply equipment. SMUD has been using the company’s electric vehicle master controller for its electric vehicle fleet implementation.

SMUD has been committed to electric vehicles since 1989 and continuously supports EV adoption. "SMUD is working with Cyber Switching to test the charge management capabilities of their EV Master Controller to determine if it can help our customers save money by avoiding the cost of an electrical panel upgrade," explained Dwight MacCurdy, SMUD energy research and development project manager. "We have been able to charge 3 to 4 fleet EVs from a single circuit using their rotational charging technology."

Cyber Switching CTO Ron Silorio commented, "We are a power management & control company, first and foremost. We've expanded our offerings to include different functionalities. In SMUD's case we become their analytical dashboard, their means of access and control. At times they don't need to rotate or power share — but that benefit is always available." For example, when SMUD has a busy day with all hands on deck, all circuits run at same time. However, in the case where longer dwell time is acceptable, SMUD can flip the EVMC into rotation mode and continue charging one vehicle for a set time and multiplex the circuit in a round-robin fashion. 

The additional cloud-based platform allows for simplicity in managing and monitoring the energy use to control demand charges, time of use, and other significant cost factors.
