ems-charge EV charging station in use

Vehicles as grid assets

Every EV is a battery on wheels. Bidirectional V2G chargers and virtual-power-plant aggregation turn parked fleets into dispatchable grid capacity — $3,359 per vehicle per year.

The Utility Problem

Idle batteries are stranded capacity.

Value

$3,359 per car, $9,000+ per truck

V2G earns about $3,359 per passenger vehicle a year and $9,000+ for heavy vehicles — while the vehicle sits idle 96% of the time.

Battery worry

Zero degradation after 1 year

Real V2G pilots show battery health with zero degradation after a year of operation — the "it kills the battery" fear doesn't hold up.

Market access

Needs an aggregator + PJM rules

One car can't bid into a wholesale market. It takes an aggregator and market-rule certification (PJM and peers) to sell the capacity.

What V2G Needs

Three capabilities, one dispatchable asset.

Bidirectional V2G charger

DC-AC conversion in both directions, so the vehicle battery feeds the grid as easily as it charges.

VPP aggregation

Aggregate thousands of vehicles into one virtual power plant that can bid frequency and capacity into the market.

ISO 15118-20 + UL 1741 SA

The communication and safety standards that make bidirectional flow legal and insurable.

The ems-charge Solution

Bidirectional chargers, one virtual power plant.

We ship the hardware and the software handshake: a bidirectional charger with ISO 15118-20 and UL 1741 SA, tied into a VPP platform that aggregates and dispatches the fleet.

  • Bidirectional DC flows energy both ways at utility scale.
  • VPP platform aggregates vehicles, bids into markets and settles revenue per car.
  • UL 1741 SA + IEEE 1547 for grid-interactive compliance.

Certified for the Grid

Compliant before it ever connects.

UL 1741 SA and IEEE 1547 for grid-interactive safety, ISO 15118-20 for bidirectional communication, UL 2202 for the charger.

Bidirectional, grid-tied

ISO 15118-20 and UL 1741 SA make the charger a two-way asset — charge at night, sell back during the evening peak.

Proof

Pilots that paid the owner back.

Bidirectional V2G chargers earn $3,359 per car per year selling energy back to the grid — with zero battery degradation after one year.
