Big Data & Cloud Computing
Big data and cloud computing platforms (AWS, Azure, GCP) are what make it possible to retain and query the terabytes of cell-formation, end-of-line test, and field-telemetry data that modern battery factories and EV fleets produce. As a hard skill it requires fluency in data-lake architectures, distributed query engines (Spark, BigQuery, Snowflake), cost-aware compute provisioning, and the controls (encryption, access policies) that govern proprietary cell-chemistry data. Engineers apply it when stitching together cell genealogy from coating to formation to pack assembly, when running fleet-wide degradation analyses across millions of cells, and when standing up the data pipelines that feed BMS over-the-air decisions.
