  1. Fiber Optic Temperature Solutions for EV Battery Testing

  2. Fiber Optic Temperature Solutions: Batteries Batteries are the key differentiator between the various EV manufacturers: 1. Battery Size 2. Battery Capacity and Performance 3. Battery Charging Time 4. Battery Life Thermal Management is the Key in EV Batteries 1. Higher Capacity and Performance with Smaller Size results into thermal stress 2. Rapid Charging requires high current and hence increases the Thermal Stress 3. Harsh Environmental and Operating Conditions i.e. Extreme Ambient Temperatures (Hot/Cold) result into Reduced Battery Life 4. High Cooling System Efficiency become very critical for Harsh Operating Conditions (Rapid Acceleration / Breaking) i.e. Supercars 5. Battery Management System: Accurate thermal profile characterization increases accuracy of Age Estimation Analytics 2
