Cheel develops internal, cell-specific temperature sensing technology for batteries, aimed at preventing thermal runaway and enabling safer, higher-performance battery systems. Unlike conventional battery management systems that rely mainly on external or surface-level data, Cheel embeds sensing capabilities inside battery cells to deliver real-time temperature data from within the cell itself. This is designed to give earlier and more accurate warning of unsafe thermal conditions, supporting applications across electric mobility, energy storage, defense, eVTOL, and other battery-powered platforms
