Workplace Electric Vehicle Charging Behavior Over Four Years

This dataset tracks over 300 employee-owned electric vehicles during a 4-year period, examining workplace charging behavior. It includes analysis of free versus paid charging and distinguishes data before and after the onset of COVID-19.

Use Cases

• Analyze charging patterns and energy consumption for over 300 vehicles to model workplace infrastructure needs.
• Compare charging frequency and duration under free versus paid charging regimes to study user behavior.
• Investigate changes in workplace charging behavior before and after the onset of COVID-19.
• Model the charging load from a fleet ranging from smaller pack PHEVs to larger pack BEVs.

Strengths

• Longitudinal data covering a 4-year period.
• Tracks a substantial fleet of over 300 vehicles.
• Includes a controlled comparison of free versus paid charging.

Limitations

• Specific column definitions and data structure are unknown, complicating analysis.
• Available file formats (HTML, BIN) are non-standard for data science workflows.
• Geographic scope and vehicle model details are not specified, limiting generalizability.
