ESM - air cooled

Waterproof ultracapacitor module.

ESM module –  Air Cooled

A heavy transport module is a dynamic energy storage source specialised in hybrid applications where the following combinations of energy sources are possible:

  • Diesel electric and ultracapacitors
  • Fuel cell and ultracapacitors
  • Batteries and ultracapacitors

Ultracapacitors are components with a very high voltage density (kW/kg) and with a relatively low energy density (Wh/kg). Combinations of 2 or more different energy sources are possible.


  • Good thermic characteristics
  • Good mechanical characteristics
  • Integrated individual cell monitoring
  • State-of-charge and state-of-health monitoring
  • Advanced active cell balancing
  • Best selection cells per module
  • Extremely small differences in cell capacity & resistance
  • Maximum braking energy storage
  • Low internal resistance
  • Long lifetime
  • IP69 housing
  • Can bus field system
  • Evaluation of the module data and adaption
