摘要：AbstractThis paper deals with the computation of the energy profile of a battery electric vehicle in order to find the optimal path in terms of travel time on a defined route in the presence of recharging terminals. The model used in this study to calculate the energy profile must respect constraints such as speed limits, desired initial and final battery energy states, and maximum terminal power. This problem can be written as an Optimal Control Problem and will be solved using the dynamic programming method in order to find the optimal speed and charging quantity at the terminal to save time. The results from a defined scenario show that recharging is done in favour of terminals with a higher maximum power and that our vehicle is constantly driving at the maximum speed allowed. The vehicle can also adapt its speed to reach the next charging station with the consideration of a waiting time at a station. The Dynamic Programming method allows us to respect the final energy constraints and shows that charging at high-powered terminals saves time.
