ems-charge EV charging station in use

Charge employees, not the demand curve

Workplace charging runs for hours, so it should never spike your peak load. AC wallboxes plus a BEMS shape the load and keep you off a grid upgrade.

The Workplace Problem

Your peak demand, not your chargers, is the cost.

Demand charges

30–70% of the bill is demand

Demand charges can be 30–70% of a commercial electricity bill. Unmanaged EV charging pushes that peak up for the whole month.

Power draw

One DC unit pulls 50–150 kW

A single DC charger draws 50–150 kW — add a few and you've created a demand spike that dwarfs the building's normal load.

Peak overlap

Charging peaks when the grid does

Employees plug in on arrival, right at the morning demand peak. A 4–10 hour stay only needs slow charge — it should be spread, not stacked.

What an Office Needs

Three capabilities, no grid upgrade.

AC wallbox fleet

7.4–22 kW per bay is all a parked employee needs — cheap to install and cheap to run.

BEMS load shaping

Schedules charging off the morning peak, caps total draw and shares capacity across every port.

TOU + solar storage

Charge on the cheapest tariff and pair with on-site PV so midday solar feeds the fleet, not the grid.

The ems-charge Solution

AC wallboxes, one energy brain.

The building already has the power — the job is to use it at the right time. A BEMS spreads charging across the day and keeps the site inside its existing connection.

  • Load shaping flattens the arrival spike so demand charges don't jump.
  • Time-of-use scheduling shifts charging to cheap, low-carbon hours.
  • OCPP 2.0.1 lets facilities meter, reserve and bill each bay by user group.

Load-balanced for the office

Metered per bay and grouped behind dynamic load balancing, so a full EV parking row never trips the building's demand charge.

Proof

Offices that dodged the upgrade.

Load shaping caps the arrival spike, so an office adds 40+ charging bays without a grid upgrade — and demand charges stay flat.
