Safety&Technology

As our ESS may operate in harsh environments with extremes of temperature and frequent charge/discharge cycles,
it is important to have "Safety-In-Design" to prevent the risk of accidents.
INCELL has a number of unique safety technologies that can prevent an initial fire
and reduce the risk of it spreading from the cell to other parts of the ESS.

Progress

Strategies

  • Remove stressors
    • ESS dedicated cells
    • Environment monitoring
    • Conservative operation
  • Detect TR early
    • Detect Off-gas early
  • Early suppression of fire
    • Built-in fire extinguisher
      (Micro capsule fire extinguisher pad)
  • Mitigate propagation
    • TR propagation prevention design
    • Fire spread prevention design
