01
Pack and cell voltages
Per-cell voltage where your BMS reports it, pack voltage everywhere else. Spread and imbalance are tracked automatically.
M-01Cell Monitor
Every cell, every fifteen minutes.
Cell Monitor pulls live readings from the BMS and telematics you already run and lays them out per pack, per cell and per depot. You see the cell that runs hot, the string that drifts and the pack that was fast-charged at noon, while it is still happening.

What Cell Monitor does
02
Temperature by sensor
Every thermistor reading over time, with ambient temperature from the vehicle location for context.
03
Current and power flow
Charge and discharge current, peak C-rate and regen events, so you can see how hard each pack is worked.
04
Cycle counting
Equivalent full cycles calculated from throughput, not just charge events, so partial top-ups are counted fairly.
05
Threshold alerts
Over-temperature, under-voltage and imbalance alerts by SMS, email or webhook, with quiet hours per depot.
06
Raw data you can export
Every reading stored at native resolution and exportable as CSV or Parquet for your own analysis.

How it runs
- 1
Connect
Point your telematics feed or BMS gateway at us over MQTT, REST or a scheduled file drop. Most fleets need no new hardware.
- 2
Map
Batteries are matched to vehicles, depots and serial numbers. Swaps are followed, so the history stays with the pack, not the vehicle.
- 3
Watch
Readings stream into the pack view within minutes. Alerts start on day one with sensible defaults you can tune.

Cell Monitor questions
Straight answers about data sources, hardware, accuracy and setup. Ask our team for anything else.
Do we need to install anything on the vehicles?
Usually not. If your vehicles already send telematics data or your BMS has a gateway, we read from that. For packs with no connectivity, we work with a list of BMS-compatible loggers.
What if our BMS only reports pack voltage?
Cell Monitor works with what is available. Health scoring and forecasts still run on pack-level data, with a wider confidence range shown on screen.
How do battery swaps affect the data?
Each battery is tracked by its serial number, so its history follows it from vehicle to vehicle and through swap stations.
