高倍率电动汽车充电器 (HREVC) 正在成为交通基础设施的重要组成部分。这是因为它们能够实现比电动汽车 (EV) 的行驶里程更长的行驶距离。通常，HREVC 需要高电网连接，这可能非常昂贵，甚至不可能。当与车外储能 (OVES) 一起使用时，由同地可再生能源供电的 HREVC 是减少安装所需电网容量的有效方法。本文通过比较静态和动态充电功率来讨论从电网为 OVES 充电的控制策略。结果发现，与静态电网充电情况相比，动态充电模式在一年内减少了 HREVC 的输入和输出。由此表明，使用动态充电策略使得 HREVC 能够安装在较小的电网连接上并使用更少的电网功率。
High rate electric vehicle chargers (HREVCs) are becoming an important part of transportation infrastructure. This is due to their ability to enable journey distances which are longer than the range of the electric vehicle (EV). Often, HREVCs need a high power grid connection which can be very expensive, or impossible. HREVCs which are powered by co-located renewable energy are an effective way of reducing the necessary grid capacity for installation when used with an Off-vehicle energy store (OVES). The control strategy for charging this OVES from the grid is addressed in this paper by comparing static and dynamic charging powers. It was found that the dynamic charge pattern reduced both imports and exports to the HREVC over one year over the static grid charge case. Thereby showing that using the dynamic charge strategy enables HREVCs to be installed on a smaller grid connection and use less grid power.
