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
