PlatformBattery storage monitoring
Catch the warm rack before it derates.
Most storage problems start small: one rack running hot, one cooling unit short-cycling. 42Hz spots them in the data your BMS already sends.

What it catches.
What goes wrong
What you’d see
42Hz
A rack running hot
Warmer than its neighbours.Same load, same weather.
Flagged with the likely cause.A cooling problem or a cell problem, not just a number.
Cells drifting apart
Voltage spread widening.A weak cell or a balancing fault.
Caught before the BMS derates.Trended over weeks, by rack and module.
Cooling falling behind
HVAC short-cycling.Or losing ground on hot days.
A maintenance call, not a derate.The case names the unit and the part.
PCS trips
The same fault code again.Temperatures creeping up inside.
One case, not ten alarms.With the trip history attached.
Capacity fading
State of health dropping fast.Usable energy below contract.
A record for the warranty claim.Health and cycling, per container.

What it reads.
It reads what’s already there. No new sensors.
- BMS: cell voltages, temperatures and state of health
- PCS: power, internal temperatures and fault codes
- HVAC: temperatures, setpoints and run status
- Fire and gas detection status
- Site controller, meters and historian
Common questions.
No. The BMS protects the cells second by second. 42Hz looks across racks and sites over weeks, and gets problems fixed.
Yes. It reads what the BMS, PCS and site controller already report. For anything unusual, our engineers build the connection.
No. It doesn’t replace fire detection or the BMS. It catches the slow problems worth fixing early.
Yes. It keeps each container’s health, cycling and temperature history.
