Summary of the simulation results of my thesis.

1. Getting more MPGfor a(Hy)truck - 3 Energy Management StrategiesSTAGE 3 – Simulations in Matlab

2. Introduction This is a follow up on my previous slide shares. This slide share will be a summary on all the simulations done for my thesis. The other slide shares can be found here:http://tiny.cc/bihpj

3. EMS Strategies The three Energy Management Strategies are: Dynamic Programming (DP) ECMS Range Extender (RE) Vehicle used is a Hytruck Driving cycles used are CSC and Je05 Configurations used: CSC: Fuel Cell: 45 kW, Battery: 60 kW Je05: Fuel Cell: 55 kW, Battery: 55 kW Configurations were most fuel efficient for the cycle

4. CSC - DP

5. CSC - ECMS

6. CSC - RE

7. Je05 - DP

8. Je05 - ECMS

9. Je05 - RE

10. Results The battery energy content was maintained during every simulation The ECMS results on the Je05 is lower , likely caused by the nature of the Je05 cycle as this happens in other vehicle configurations as well.

11. Results - discussion ECMS provides results that approach DP, though ECMS can be applied online The Range Extender is a lot easier to implement (set at a fixed, right chosen power level), but comes at a higher fuel cost Measurements only done for Range Extender EMS, due to technical difficulties it was not possible to control the fuel cell power dynamically enough to do the DP and ECMS settings on the test rig

12. Future / Recommendations Next: Finalize report Recommendations: Increase level of control on the exact power of the fuel cell (enabling DP / ECMS measurements) Increase measurement/estimation on the energy content of the battery to verify battery status after measurement
