Interested in our BMS?
Our proprietary BMS is designed for second-life cells — cells with dispersed states of health that generic BMSs handle poorly. For integrators, storage assemblers and manufacturers.
cirBATT proprietary BMS
A BMS designed for heterogeneous cells
Reused cells don't all share the same capacity or internal resistance. A standard BMS, designed for perfectly matched new cells, handles that spread poorly — and throttles the pack. Ours is developed in-house precisely for this.
Active & passive balancing
Compensates for the spread in state of health between cells to maximise the pack's actually usable capacity.
Per-cell monitoring
Voltage and temperature tracked cell by cell, with state-of-charge (SOC) and state-of-health (SOH) estimation.
Multiple protections
Over-voltage, under-voltage, over-current, short-circuit, over/under-temperature. The BMS is the first barrier — see the cell's internal protections (CID/PTC).
Communication & supervision
CAN and RS485 buses, configurable thresholds and data logging to control and supervise your installations.
Fits into your products
- Configurable. Number of cells in series, protection thresholds and chemistry (LFP / NMC) adapted to your pack.
- Consistent with our ecosystem. Designed to work with our already-tested second-life cells and packs.
- Technical support. A dedicated contact and documentation to integrate the BMS into your assemblies.
- Designed in France. Design and support from our Grenoble workshop.
Let's talk about your project
Describe your pack and your need (number of cells in series, chemistry, expected communication) — we'll get back to you with a proposal and, on request, the datasheet.
