Battery-Health Conscious Energy Management Optimization of Plug-In Hybrid Electric Delivery Vehicle

Considering the impact of battery life on the life cycle cost of plug-in hybrid delivery vehicles, a multi-objective optimization study on battery charge and discharge power is carried out with the goal of minimizing comprehensive fuel consumption and battery life attenuation. The weight coefficient is introduced to transform the multi-objective optimization problem into a single-objective optimization problem. And use the dynamic programming (DP) algorithm to solve the problem of global optimization, and the optimal weight coefficient is selected according to the optimization result. The simulation results show that, this method has effectively reduced the battery life attenuation degree while ensuring fuel economy, and the life cycle cost of hybrid electric vehicles was optimized. Besides, it can provide research support and evaluation benchmarks for other types of energy management optimization strategies.
