No transformer upgrade needed, install more chargers anyway.
Your site already runs a good number of chargers, and you want to add more to earn more. But transformer capacity is maxed out, and the old "one charger, one line" logic makes capacity the hard ceiling.
Existing chargers already consume the transformer's usable capacity. Adding new chargers to earn more is blocked by the capacity ceiling.
Transformer upgrades take half a year or more. That gap is enough for competitors to capture the best sites and lock in core customers.
Most of the time total site power sits far below the ceiling; only rare peaks approach the safety line. Expanding for a few peaks is uneconomical.
Existing chargers consume the transformer's capacity. To add more, there are only two fallbacks: stop adding chargers, or wait for expansion.
Capacity maxed out, no more chargers can be installed. Watch customers queue and churn while revenue hits a ceiling.
Apply for an upgrade: high cost, long cycle, and the new capacity soon fills up again. Treats the symptom, not the cause.
The real answer: build a "dynamic matching mechanism" between elastic demand and rigid capacity, making charging demand "obey" the transformer's capability.
Just one smart charging gateway, no solar or storage needed. Let the existing transformer over-subscribe to support more chargers. Total power never exceeds the limit, and every vehicle still gets charged.
The gateway meter samples transformer total power every second and sends it to the gateway over RS485. The system's "eyes".
The gateway gathers charger status, compares against the safety threshold, computes the optimal allocation when overrun is forecast, and dispatches within one second.
Under communication loss or gateway outage, every charger automatically holds a floor power limit. No single point of failure can overload the transformer.
The gateway ensures the ceiling is never breached, the gateway meter provides second-level data, and the cloud platform adds optional remote monitoring.
Ensures the transformer ceiling is never breached. Runs locally, independent of the cloud.
The gateway's "eyes". Installed on the transformer's low-voltage side, sampling three-phase voltage, current, and power every second.
The gateway runs standalone. With the cloud: remote monitoring, history analysis, alerts, and remote parameter tuning.
No civil works or expansion. From inquiry to operation in weeks. Future upgrades only change gateway parameters, never the equipment.
