6. Conclusions

In this chapter, the energy efficiency of a series hybrid transit bus powered by a CNG engine and supercapacitors was evaluated. A mathematical model was established, and three different control strategies were designed. The performance characteristics of two rule-based control strategies were compared to the result of the optimal control using dynamic programming. Based on our analysis, the following can be concluded:


Performance Evaluation and Control Strategy Comparison of Supercapacitors for a Hybrid… DOI: http://dx.doi.org/10.5772/intechopen.80948
