Warranty as a data product
Turning operating data into a defensible — or contestable — warranty position.
Treating the BESS warranty as a data product means continuously measuring the operating conditions and degradation the contract actually cares about — SoH curve, energy throughput, SoC/temperature windows, C-rate — so that a claim is backed by evidence and an exclusion can be contested rather than assumed.
Definition
BESS warranties hinge on two limits (capacity retention and energy throughput) plus operating-window conditions whose violation voids cover. Most operators discover where they stand only when a dispute arises. As a data product, the warranty position is computed continuously from SCADA/BMS data and kept claim-ready.
Typical range
Warranty floors: ≥70% SoH at 10 years (or ≥60% at 20), plus an energy-throughput cap in MWh/EFC. Exclusions commonly cover SoC-window, temperature-window, cycles/day, and C-rate violations.
Why it matters
Warranty disputes are won or lost on data. If you can show degradation exceeding 2× the contracted curve while staying inside every operating window, you have a claim. If the OEM can show a temperature- or SoC-window violation, they have a defence. Whoever holds the better-instrumented record wins.
How NuraVolt tracks it
NuraVolt continuously tracks SoH against the contracted curve, accrues EFC against the throughput budget, and logs every SoC-, temperature-, and C-rate-window event with the cell-level evidence (voltage histograms, 90-day temperature and SoC traces, BMS fault logs) that an OEM claim requires.
