EMS SOFTWARE
Battery energy storage
managed by Powerize EMS
Powerize EMS controls battery energy storage (BESS) at charging hubs, industrial sites and solar installations. It charges the battery when energy is cheap, discharges when it is expensive and keeps you within your grid connection limit.
What the EMS does
Automatic battery control based on energy prices and grid load.
Price-based charging
The battery charges and discharges automatically based on day-ahead market prices. Prices can also be uploaded manually from CSV or Excel.
Peak shaving
The battery covers demand peaks, for example when several fast chargers run at once, so the grid connection is not overloaded.
Grid import limit
A fixed grid import limit or a dynamic limit based on transformer load.
Energy reserve
A minimum state of charge and an emergency reserve mode for power outages.
Works offline
An industrial computer with a touchscreen and local web interface runs on site. Control continues even without internet or the cloud.
Multi-site dashboard
Live status, event and alarm logs, charge history and revenue and savings reports across all sites.
How deployment works
- Analysis. We review your load profile, grid capacity and goal: savings, peak shaving or backup.
- On-site hardware. We install an industrial computer with a 4G modem and a spare unit, connected to the battery over RS-485.
- Configuration. We set operating strategies, power limits, reserves and user permissions.
- Operation and reports. The system runs automatically and you see the results in the dashboard.
Energy storage and EMS: FAQ
What is an EMS?
An EMS (Energy Management System) is software that decides when a battery should charge and when it should discharge, based on prices, consumption and grid limits.
Why add energy storage to a charging hub?
The battery covers the peaks of fast chargers, so the hub can charge at higher power than the grid connection alone allows, at a lower energy cost.
Does the EMS work without internet?
Yes. Control runs locally on the on-site device, and there is a spare unit on site. A satellite link can be added as an option.
Do you sell batteries?
We provide the EMS control system. It works with the battery chosen for your project, and we help you size it.
