Mahindra Electric Uses System-Level Simulation to Optimize Battery Thermal Management System for an Electric Vehicle
Key Outcomes
- Created and validated a system-level simulation model for an electric vehicle with battery, cooling circuit, refrigeration circuit, vehicle, and driver
- Developed concepts and tuned parameters to choose the best components at its best operating point
- Developed new compressor operation logic and tested it for better energy efficiency
Electric vehicles (EVs) are powered by lithium-ion batteries, which require an effective but low-power-consuming battery thermal management system (BTMS). The Mahindra Electric team developing algorithms for a BTMS for EVs needed to understand the best configuration of cells for maximum cooling and develop an efficient algorithm for the cooling circuit.
Using prior experience with Model-Based Design, the team created and validated a system-level simulation model for an electric vehicle with battery, cooling circuit, refrigeration circuit, vehicle, driver using Simulink® and Simscape®. They used this model to develop concepts and tune parameters to choose the best components at its best operating point.
