Analysis of Optimal Battery State-of-Charge Trajectory for Blended Regime of Plug-in Hybrid Electric Vehicle

The paper deals with an analysis of optimal battery state-of-charge (SoC) trajectory profile for plug-in hybrid electric vehicles (PHEV). The case of blended operating regime is considered, where hybrid driving mode is enabled during the whole trip. The analysis relates to a SoC trajectory length minimization pattern observed in optimal SoC trajectories obtained by using dynamic programming-based optimisation of PHEV powertrain control variables. The emphasis is on analytical interpretation of the optimal SoC trajectory pattern from the perspectives of simplified battery only system and the whole PHEV powertrain. Also, the impact of engine specific fuel consumption characteristic on the optimal SoC trajectory solution is analysed.
