48V Mild Hybrid Lithium-Ion Battery Pack Test Data

U.S. Environmental Protection Agency data supports the validation of a 48V lithium-ion battery model for mild hybrid electric vehicles. The dataset contains battery test data from hardware-in-the-loop simulations over U.S. regulatory drive cycles, matching charge and discharge data from chassis dynamometer testing of a 2013 Chevy Malibu Eco.

Use Cases

• Validate equivalent circuit battery models using simulated battery voltage, current, and state of charge (SOC) data.
• Analyze energy flows and CO2 emissions for mild hybrid electric vehicles over EPA regulatory drive cycles.
• Compare hardware-in-the-loop test data with vehicle test data for battery voltage and current across different drive cycles.

Strengths

• Data originates from the U.S. EPA National Vehicle and Fuel Emissions Laboratory (NVFEL) in Ann Arbor, Michigan.
• Battery model validation uses test data from a specific 8 Ah, 0.4 kWh, 48 V lithium-ion battery pack from A123 Systems.
• Validation testing was performed using a hardware-in-the-loop system simulating U.S. regulatory drive cycles.

Limitations

• The dataset is associated with a 2018 publication and may not reflect the latest battery technologies or testing standards.
• Specific data volume, row count, and column structure are not provided in the input.
• Data is focused on a single battery pack configuration (14S1P) from one supplier, limiting generalizability.
