During manufacturing and assembly of electric vehicle battery packs, monitoring the battery temperature at multiple points is critical, demanding precision measurements across many signal types, temperature ranges and multiple channels (usually more than 20). For this reason, a built-in battery temperature management system is required in all electric vehicles. The system serves as a test validation system and helps predict systemic failures, redundancy, and batch traceability during design and manufacturing.
Based on temperature deviation anomalies, the temperature monitoring system quickly warns you of potential battery defects, helps isolate fault locations, and detects thermal imbalances, hotspots, temperature-related performance, and capacity degradations in battery packs. Thermal imbalance is minimized by using a battery management system (BMS) to cell balance, equalize voltages and state of charge among the cells in a battery pack at a full charge.
