The question we hear most from commercial sites, housing societies and malls is simple: we want more chargers, but our electricity connection is already close to its limit. In many cases the answer is not a bigger connection. It is smarter control of the one you have.
Why the nameplate total is misleading
Ten 60 kW chargers have a combined rating of 600 kW, but they almost never draw that at once. Vehicles arrive at different times, with different states of charge, and most batteries slow their charging rate as they fill up. Sizing a connection for the theoretical maximum means paying for capacity that sits unused nearly all the time.
What dynamic load balancing does
A load management system measures the building's total demand in real time and shares whatever capacity is spare between the chargers that are active. When the building's own load rises, chargers slow down. When it falls, they speed up again. The site never exceeds its sanctioned load, and vehicles still leave with the charge they need.
- Static limits cap the charging group at a fixed figure. Simple, but leaves capacity unused at night.
- Dynamic limits follow the building's actual consumption from a meter at the main incomer.
- Priority rules give fleet vehicles, departing vehicles or paying customers first claim on available power.
Using time-of-day tariffs
Many commercial and industrial consumers in India are billed with time-of-day tariffs, where energy costs less during off-peak and solar hours and more in the evening peak. A charging system that knows the tariff can shift flexible charging, such as fleet vehicles parked overnight, into the cheaper windows automatically. The same logic helps reduce the maximum demand charge that appears on every commercial bill.
Shifting flexible charging out of the evening peak lowers your energy bill and eases pressure on the local grid at the same time.
Pairing with solar and storage
Where a site has rooftop solar, smart charging can soak up midday generation that would otherwise be exported for little value. Battery storage goes a step further, charging slowly from the grid and releasing energy quickly to support high-power chargers. That is how a modest connection can still offer fast charging to drivers.
Open standards matter
We build on open protocols such as OCPP so chargers from different manufacturers can be managed from one platform, and so sites are not locked into one vendor's hardware. It also means load management rules can be updated in software as the site grows, without replacing equipment.
Where to start
A good first step is a load study: a few weeks of metering at your main incomer, combined with how you expect vehicles to use the chargers. From that we can show how many chargers your current connection supports with smart control, and when an upgrade would actually be worth it. Talk to PxT Energies to arrange one.
