Entrust V2H Charger -- Bidirectional DC/DC Charger for V2H Applications

在过去的几年里，电动汽车电池的价格一直在下降，性能，如能量密度(千瓦时/公斤)一直在提高，这(加上零排放承诺)推动了电动汽车的快速增长。电动汽车电池正在成为通过储能能力提供能源灵活性服务的头号资源，而储能能力对于大规模的风能和太阳能发电至关重要。这为V2H条款提供了巨大的市场机会，如支持家用太阳能光伏发电的自用；平衡电网的电力需求，特别是增加非高峰电网电力的使用，降低高峰电力需求；并参与需求侧响应和频率响应服务。该项目将开发具有V2H/V2G功能的新型/市场导向的智能双向电动汽车充电器及其相关控制系统，用于家庭物业和路外停车，并将智能家居电动汽车充电器集成到智能家居微电网中，开发智能家居电动汽车充电器与智能家居微电网控制器之间的通信，以监控V2H功能。由于创新的V2H功能，智能家居电动汽车充电器将通过最大限度地利用太阳能光伏装机容量和太阳能光伏发电的自耗来提高智能家庭微电网的性能，通过减少电池存储容量来显著降低成本，增加错峰用电，降低电网高峰用电需求，提高电力效率。项目成果将促进电动汽车增长和净零运输；为能源灵活性服务提供主要资源；推动国内物业太阳能光伏安装；在解决能源安全、贫困、可负担性和可持续性以及气候变化方面发挥关键作用；促进电动汽车充电标准创新，使V2H/V2G成为商业上可行的解决方案。

EV battery price has been decreasing and performance, such as energy density (kWh/kg), has been improving in the last few years, which (along with zero emission commitment) drive the rapid growth of electric vehicles. EV batteries are becoming the No.1 resource to provide the energy flexibility services through the energy storage capabilities, which are essential for large-scale wind and solar energy/power generation. This provides tremendous market opportunity for V2H provisions, such as supporting self-consumption of home solar PV power; balancing power demand on the grid, particularly increasing use of off-peak grid electricity and reducing peak power demand; and participating in the DSR (demand side response) and frequency response services.The project will develop a novel/market-focused smart bidirectional EV charger with V2H/V2G capabilities and associated control system for domestic properties with off-street parking, and integrate the smart home EV charger within a smart home microgrid, and develop the communication between the smart home EV charger and the smart home microgrid controller for supervisory controlling the V2H functions.Due to the innovative V2H functions, the smart home EV charger will enhance the performance of the smart home microgrid through maximising solar PV installation and self-consumption of solar PV power, significant cost reduction by reducing battery storage capacity, increased use of off-peak grid electricity and reduction of peak power demand on the grid, and improved power efficiency.The project outcomes will facilitate EV growth and net zero transportation; provide a major resource for energy flexibility services; promote domestic property solar PV installation; play a key role in addressing energy security, poverty, affordability and sustainability, and climate change; facilitate EV charging standard innovation to make V2H/V2G a commercially viable solution.
