Fiber Optic Temperature Solutions Batteries

• Batteries are the key differentiator between the
  various EV manufacturers
• Battery Size
• Battery Capacity and Performance
• Battery Charging Time
• Battery Life

• Thermal Management is the Key in EV Batteries
• Higher Capacity and Performance with Smaller Size
  results into thermal stress
• Rapid Charging requires high current and hence
  increases the Thermal Stress
• Harsh Environmental and Operating Conditions i.e.
  Extreme Ambient Temperatures (Hot/Cold) result
  into Reduced Battery Life
• High Cooling System Efficiency become very
  critical for Harsh Operating Conditions (Rapid
  Acceleration / Breaking) i.e. Supercars
• Battery Management System Accurate thermal
  profile characterization increases accuracy of
  Age Estimation Analytics
