Hybrid Battery System Engineering

FutureMotiv can deliver complete system engineering for the specification of a hybrid battery including battery management and safety features:

Alignment with powertrain performance goals and regional environmental boundaries(e.g. temperatures)

Definition of use cases, load management and safety features:

  • Charge process and balance strategy (passive vs. active balancing)
    Development of charge and recuperation strategy aligned with cell performance values
  • State of Charge(SoC) value definition and calculation
    Definition of power train load management in alignment with SoC values derived from cell characteristics
  • Development of common powertrain error state matrix and resulting safe system behaviour
  • Development of high voltage relay circuit including pre-charge and safety features to cover relay malfunction(relay diag, interlock etc.)
  • Development of thermal management and definition of influence of SoC and load management (low vs. high cell temperature
  • Definition of isolation guard

Development of safety guidance/manual for service application
Extension of CAN communication matrix for additional values to be communicated via CAN
Guidance for package (esp. crash performance)
