Aboard realised the integration, the control and the electric monitoring for a hybrid refregirated unit, driven by a diesel engine and an electric motor.

Architecture of the demonstrator:

  • 3 power sources possible: ErDF380 VAC network, Li-ion batteries and driven by diesel engine generator.
    • When batteries are used as electrical power generation system, the high voltage of the DC bus is gain by DC/DC converters
    • When the ErDF network or the generator are used as electrical power generation system, the batteries are recharged via the DC/DC converters
  • Liquid cooling of the DC/DC converters
  • Piloting, monitoring, managing the componets cooling with an embedded microcontroller
  • Remote monitoring of the system with an on board GPS/UMTS modem
