The SPAC battery management system sits at the core of the Blue Sphere AC block. It actively balances cells in operation, monitors every layer of the electrical system and calibrates available energy so the platform stays safe, observable and dispatchable throughout its working life.
Voltage, temperature and impedance are monitored on every cell, with tiered protection that isolates faults before they propagate.
String, module and DC-bus monitoring guards against insulation faults, over-current events and arc-flash conditions.
Adaptive state-of-charge and state-of-health estimation across temperature and ageing regimes, for accurate dispatch.
Continuous recalibration of usable energy so market bids reflect the true deliverable capacity of the platform.
In-operation balancing eliminates the cell drift that would otherwise strand capacity and shorten platform life.
Thermal management is engineered into the AC block, keeping modules within a controlled temperature band across climates.
The BMS platform we deploy has been iterated across live utility, commercial and industrial projects globally. Firmware, safety envelopes and balancing algorithms are continuously refined against real-world dispatch data.
