Discharge Process: During the discharge process, the battery’s chemical reactions undergo a reversal. Lithium ions migrate from the negative electrode to the positive electrode, while electrons travel from the negative electrode to the positive electrode.
For EV users, the goal is to minimize the total cost of electricity and battery degradation. Additionally, the performance constraints of charging piles and EVs, travel-habit constraints of EV owners, and electricity prices in the electricity market are also considered.
Finally, the model was validated using an apartment building as an example. The results indicate that, under the normal travel habits of users, with the goal of minimizing company expenses, the annual cost of the company reaches its minimum at a certain number of charging piles.
The stakeholders of the charging pile are categorized into two groups: companies and EV users. Distinct objective functions are proposed for each group of stakeholders. For companies, the objective function is to minimize the combined cost of electricity and investment fees.
The Optimization Goal Is to Minimize Company Expenses When a company operates and builds its own charging pile, the cost consists of three parts: (1) the company’s daily load, (2) the construction cost of charging piles, and (3) providing emission subsidies for EV users. The company’s revenue is the charging service fee paid for vehicle charging.
The constraint on the charging and discharging power of EV batteries is shown in Equation (15): where is the maximum discharge power of the battery. is the maximum value of battery charging power. The specified discharge power is negative and the charging power is positive.
