EV Charging Infrastructure
Design the charging site, not just the charger.
AC, DC fast and ultra-fast products supported by whole-site electrical, civil, software and operating planning.

Understanding EV Charging Infrastructure
EV charging infrastructure connects vehicles to safe, managed power. The charger's rating matters, but the site's supply capacity, the connector family the vehicles actually carry, their battery voltage, the time they stand still, the protection and earthing at the supply board, the software and the operating model determine the right solution.
Match equipment to vehicles, time and available site power. Charger power is useful only when the service, transformer, protection, cables, parking flow and operating model can support it together.

Charging site, drawn
Start with the vehicle. The site fills in behind it.
Design a charging site from the load back to the supply: the vehicles first, then the chargers, the distribution board and protection, and a transformer only where the service cannot carry the load.

Illustrative arrangement, not a record of a Metro Power installation. The chargers, switchboard and transformer are product images; the utility supply, protection devices and parking bays are drawn.
01 Start with the need
Who needs to charge, and how long can they stay?
Vehicle use and time on site come before a charger count.
The vehicles
Start with the fleet. Connector family, battery voltage class, the energy each vehicle needs per day and how long it stays parked decide everything below.
02 Choose the mix
Which charging speed fits that visit?
AC and DC are different answers to dwell time and turnaround, not interchangeable boxes on a plan.
Chargers
Choose for dwell time, not the nameplate. AC where vehicles stay for hours, DC where turnaround is short. One outlet serves one connector family.
03 Manage the demand
What happens when vehicles charge at once?
The board and protection must match the simultaneous demand that the site will allow.
Distribution board
Size the feeders for charging at once. The single-line gives each charger its per-phase current, so the board carries the simultaneous load that load management allows.
Protection
Protect for DC leakage and earth the site. Residual-current protection rated for DC leakage, surge protection and a sound earthing arrangement are checked before the chargers are energized.
04 Confirm the supply
Can the existing service support the plan?
Check the current connection before assuming a transformer upgrade or a charger quantity.
Transformer, where required
Upgrade only where the service cannot carry it. Confirm the transformer rating and loading, the service voltage, site peak demand and the distribution utility’s requirements.
Utility supply
The connection sets the ceiling. Available service capacity and the demand already on it set the practical limit for every choice above.
From the drawing to your site
What do you already know about your vehicles and electrical service?
Bring the vehicle types, expected parking time, site load and available service information. If something is missing, the guided workspace will show what to check next.
Charging with storage behind the meter
Keep charging demand within the site power limit.
The site power limit is the highest grid import the connection can safely and contractually carry. The building already uses part of it. What remains is the charging headroom. This drawing shows how managed charging and a battery can work within that real limit.
Charging site with a battery behind the meter
The chargers, the building and the battery share one supply. While the grid is present the energy management system (EMS) measures import at the main switchboard and keeps it below the limit the connection allows. When several vehicles charge at once, the battery covers the burst instead of the grid. When the feeder fails, the transfer switch separates the site and the battery keeps the critical load on.
What the site needsAn import limit agreed for the connection, chargers the EMS can command over OCPP, and, where the site must ride through outages, a transfer switch with anti-islanding protection under an interconnection agreement with the distribution utility.
Ordinary demand. The utility and the solar supply the site and the battery recharges between sessions. The EMS shares the headroom under the import limit among the chargers.

EV CHARGING BENEFITS · TWO PERSPECTIVES
Reliable charging for operators. A simpler journey for drivers.
A successful charging system combines electrical capacity, the right charger mix, load management, software and support. The charger alone does not create the service experience.

Follow the journey from physical equipment to the decision a customer or operator can act on.
- 01 · Product photograph
Capture
The utility service and transformer set the site's power ceiling. Each step up in charger power is a step up in supply current, and the step from one tier to the next is usually a change to the site rather than to the charger.
- 02 · Product photograph
Connect
Switchgear, DC-sensitive leakage protection, earthing, cabling and civil works deliver the power safely; they are checked by the electrical inspector at energization.
- 03 · Product image
Understand
Chargers are matched to dwell time, to what the vehicles accept, and to the connector family each vehicle carries: CCS2, CCS1, CHAdeMO or GB/T for DC, Type 2 or Type 1 for AC. One outlet serves one family.
- 04 · System layer
Act
Open Charge Point Protocol (OCPP) management, access and payment support the operation where the charger publishes OCPP support; not every charger family does.
