Diagnostics
When EMS still looks normal, determine whether a signal is likely a data-quality issue or a real battery/system problem — then recommend the next engineering step.
BESS Diagnostics
Independent BESS diagnostics and performance analysis — early anomalies, mixed-vendor signals, and degradation you can act on.
When EMS still looks normal, determine whether a signal is likely a data-quality issue or a real battery/system problem — then recommend the next engineering step.
Read modules, PCS, and EMS together. Compare peer racks, isolate a rack or string, and recommend what operations should do next.
Assess SOH and lifetime from operating and test data — not only from datasheets or warranty assumptions.
I first examine data quality and measurement context before interpreting anomalies or degradation. I combine operating data, test data, and system signals to determine what the data can — and cannot — support.
Before deciding what is wrong, determine whether the data supports the conclusion.
BESS Diagnostics is the independent consulting practice of Anthony Chou, Ph.D. Work focuses on system-level BESS analysis and integration, supported by hands-on battery and system testing up to approximately 500 kW.
Typically remote from Houston, with site or vendor calls when needed.
