ISO 15118作為電動汽車與電動汽車供電設備（EVSE）之間通信的國際標準，在儲能之間的能量交換中發揮著重要作用。本論文分析了智能家居環境中電動汽車充電應用的 ISO 15118 標準。通常，如果連接器插入或遵循 EV 充電計劃，則 EV 家用充電器會立即開始充電過程。這種充電行為沒有考慮其他家用電器的用電量，可能會導致使用電量超過合同電量的懲罰。因此，我們提出了一種結合家庭電池儲能和家庭能源管理系統（HEMS）的靈活可控的雙向充電和放電策略，以通過MQTT通信降低電動汽車和家用電器的總電力成本。此外，仿真係統由飛鴻交流 10 kW 雙向 EV 充電器 Chroma 61860 構建，用於 EV 電池和電網系統。最後，從實驗結果來看，與正常的非受控充電系統相比，電力成本低於20%。;ISO 15118, as an international standard for communication between the EV and the EV supply equipment (EVSE), plays an important role in exchanging energy between energy storage. This thesis analyses the ISO 15118 standard use for e-mobility charging applications in a smart home environment. Usually, the EV home charger immediately starts the charging process if the connector plug-in or follows the EV charging schedule. This charging behavior does not consider the power consumption from other household appliances and may cause a penalty for the high used power over than contract power capacity. Therefore, we propose a flexibly controllable bidirectional charging and discharging strategy integrated with home battery energy storage and home energy management system (HEMS) to lower the total power cost of EV and household appliances over MQTT communication. Furthermore, the emulation system is constructed by Phihong AC 10 kW bidirectional EV charger, Chroma 61860, for the EV battery and power grid system. Finally, from the experimental results, the power cost is lower than 20% compared with a normal non-controlled charging system.
