Battery monitoring

Every cell, not just the string.

Per-cell voltage and temperature, up to 250 batteries.

Wired daisy-chain battery monitoring probe: per-cell voltage and temperature monitoring for up to 250 batteries on a single controller. Part PCT-EH05DBM0315-PR.

Up to 250 probes per controller

One probe per battery, one daisy chain.

The PCT-EH05DBM0315 probe mounts directly on each battery and reports voltage and temperature to the Prochista Control Unit over a simple RJ-11 daisy chain. No per-probe wiring runs, no separate gateway per cell.

Voltage + temperature per battery

Each probe reports its cell's real-time voltage (0.1 V on 12/24 V, 0.01 V on 2 V cells) and temperature (1 °C resolution) to the controller, directly, not estimated.

250-probe string

One cable, 250 nodes

Standard RJ-11 dual daisy-chain bus, with no per-probe home run and no extra switches. Up to 250 probes on one chain, up to 3 m between adjacent probes.

2500 V optical isolation per cell

Every probe is optically isolated from the next, so a single bad cell or wiring fault never propagates into the rest of the string or to the controller.

Per-cell, not per-string

Six failure modes a bulk meter calls noise.

Bulk-string monitoring sees an average. The Battery Monitor Probe sees every cell, so drift, heat and capacity fade surface as a single ranked alarm instead of hiding in the mean.

One number for the whole string. A failing cell hides in the average.

Per-cell probes

Cell 14: drift + heat

Every probe reports its own cell, so the one that's failing is obvious.

Capabilities

Six things that make it a fit for critical DC plant.

Every item is straight from the datasheet, for 24 V, 12 V (-PR) and 2 V (-PRL) cell banks.

Multi-voltage cells

24 V, 12 V (PR) and 2 V (PRL) cell variants, same controller, same monitoring stack.

High-resolution voltage

0.1 V on 12–24 V cells, 0.01 V on 2 V cells, enough to spot drift before a string failure.

Per-cell temperature

Built-in sensor, -30 °C to +70 °C, 1 °C resolution. Catch a degrading cell weeks early.

LED notification per cell

A green/amber/red status LED on each probe gives a tech instant per-cell health, no laptop.

2500 V optical isolation

Every probe optically isolated from the chain, for fault tolerance across the whole string.

Tiny, light, cool

58 × 42 × 24 mm, about 70 g, 60 mW max. Fits on any battery and runs from the cell it monitors.

Installation

A 250-cell string instrumented in a single visit.

The probe is powered from the cell it monitors and reports over the same RJ-11 daisy chain. No separate power, no per-probe IT cable, no string shutdown to install.
