Main objective of OSEM-EV is a comprehensive thermal management system by novel electro-thermal architectures and control algorithms, including thermal insulation, thermal storage, innovative heating and cooling approaches applied to the powertrain (battery, inverter and motor), battery life duration enhancement as a side effect of thermal management, electronic control of energy and power flows, energy efficiency of electrified accessories as well as energy substitution and harvesting functions.

Electro-thermal Simulations of Battery Systems

 

Electrical model

  • Current profile as input
  • Dissipation calculated with Rs is strongly temperature dependent

 

 

 

Thermal model

  • Dissipation as input
  • Calculate resulting temperature distribution

 

 

 

Issue: long FEM simulation time

  • Example: Simulation of 1000s for one cell on 4 CPUs @ 3.4GHz with maximum time step of 1s -> 2000s

 

 

 

 

 

 

WP1 Requirements

Range limitation, due to the limited storage capacity of batteries, is one major issue in electric vehicles. The main challenge in this project is to achieve a systematic energy management of the vehicle, based on the integration of new electro-thermal energy management strategies and new subsystems, and focusing on solutions for solving the state-of-the-art major issues in electric vehicles. The energy consumption of the auxiliaries (e.g. climate control) and accessories, using part of the electric energy from the battery, are still worsening the global picture. In extreme conditions, up to 50% of the batteries’ capacity is absorbed by these subsystems. The systematic management of energy in electric vehicles is a mean to gain extended range without sacrificing comfort. The challenge is therefore to extend the range of electric vehicles in almost all climatic conditions. In this work package, the requirements of the concepts and solutions intended to be developed for the key subsystems in electric vehicles are specified.

Work Package 1 is led by DAIMLER AG.
