EV Fleet Battery Efficiency Logs
This dataset provides granular, real-time logs of electric vehicle (EV) fleet battery performance, including charge cycles, range efficiency, battery health, and degradation trends. Designed for fleet managers and sustainability teams, it enables detailed monitoring, optimization, and benchmarking of EV battery usage to support cost reduction and climate goals. The dataset is ideal for operational analytics, predictive maintenance, and sustainability reporting.

Behind this dataset
Same schema. As many rows as you need.
These 90 rows came out of a blueprint — 20 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.
Rules it was built with
- Each row represents a single vehicle's daily summary.
- Include battery state-of-charge, kWh consumed per mile, and charge duration.
- Capture ambient temperature and average payload weight for context.
- Flag entries with efficiency below fleet baseline for review.
- Log charging location as depot or public station.
