High Current EV Charging
Many commercial and municipal fleets are turning to alternative fuel vehicles
for their fleet deployments. Medium- and Heavy-duty Electric Vehicles are gaining more and more popularity as true zero-emission
solutions. The manufacturers are rolling new zero-emission EV buses, trucks, and vans and Commercial and government fleets are deploying
them at a growing rate.
These vehicles require high-current charging, which presents a serious challenge. Often fleet facilities are being required to make wholesale, and expensive, upgrades to the power infrastructure to provide the needed electrical power to charge these new sustainable medium- and heavy-duty vehicles. In many cases, there is a need to pay tens of thousands of dollars to utilities just for transformer upgrades so that the additional necessary power is provided.
Introducing the EVMC-HC
The Electric Vehicle Master Controller – High Current, or EVMC-HC, provides the same
electrical infrastructure cost reductions offered by Cyber’s current Electric Vehicle Master Controller, or
EVMC, but is uniquely manufactured for the greater electrical voltages and current of buses and
trucks. Using the company’s patent-pending rotational charging capability, the EVMC-HC reduces the cost of traditional electrical
infrastructure needs by up to 75% while still providing the necessary charging requirements of most fleets.
The EVMC-HC sits between the electrical panel and the charging stations, allowing a single high-current circuit to power up to four
charging stations. Cyber‘s patent-pending method switches the power to multiple charging stations in a “round-robin” scenario, rotating
on a programmable, timed basis. The system polls the vehicles charging status as well, and if at capacity it switches to the next bus
or truck in the rotation. The EVMC-HC modular design allows for all types of high-current needs, from DC fast chargers, to heavy-duty bus
or truck chargers.
Demand Charge Savings
The second challenge in deploying EV trucks and buses as part of their green initiatives is the impact of the demand charges on operational
budgets. Demand charges alone may create major cost over-runs as these medium- and heavy-duty electric vehicles need a
lot more power than consumer EVs. Demand Charges can be a serious impediment to fleet deployment of high-current electric vehicles as the
surge in demand when connecting a large number of high-current chargers at the same time would be very large. This would result in a serious
increase in the demand charge fee.
