Energy storage orchestration for DCFC sites

opportunities for BESS

evPower.ai provides a hardware-agnostic solution that plugs seamlessly into any existing DCFC site to maximize RoI and driver experience using proprietary field-proven ML models.

BESS at DCFC sites today

One mode at a time: suboptimal and uncertain RoI

DCFC operators deploy BESS for one of two reasons, and commit its full capacity to it:

Energy arbitrage

Charge the battery when energy is cheap (off-peak), discharge it when energy is expensive (peak).

DownsideMargins change year-round and can shrink to almost nothing in some months.

Peak shaving

Supply power beyond the site limit: the grid connection, or a virtual limit set to reduce demand charges.

DownsideRevenue potential is volatile and brings uncertain returns.

The evPower solution

One battery, both strategies, re-optimized every 5 seconds

evPower seamlessly increases BESS RoI and the site's quality of service, using smart ML algorithms and real-time power control over the BESS and the chargers.

How it decides

01

Per-site forecast.

A model trained on the site's own sessions predicts demand, peak windows and tariff spread, then splits battery capacity between peak shaving and arbitrage.

02

Joint dispatch with AI-DLM.

One engine allocates power to every connector and to the battery, so each discharged kWh goes where it earns most: an EV that would otherwise be throttled, or the peak tariff.

Simulated DCFC site: 24 hours, 540 kW grid connection, five dual-port DC chargers offering a total of 1,320 kW, 600 kWh 0.5C BESS, peak tariff hours 5–10 PM, ToU tariffs. Profit gain baseline is the same site without BESS. Driver experience score: higher is better.
