摘要
基于目前电动汽车产业发展的困境认识,提出未来电动汽车技术发展与商业实现的VEG模式(Vehicle-Energystation-Grid)。在VEG模式中,电动汽车充电方式由用户自己选择,可以在能量站快充,也可以在停车场或家庭车库进行慢充。能量站安装有低成本、长寿命的MW级储能电池,能够从电网充电储存电量后给电动汽车快速充电;同时,能量站能够与电网互动,用于电力调峰或调频。作者认为,开发低成本长寿命的新型储能电池和可以安全快速充电的新型动力电池是实现VEG模式的两大技术关键。只有这两大技术关键突破后,纯电动汽车产业发展的春天才能够真正到来。
Based on the understanding of technological developments for electric automotive industry in China, a Vehicle-Energy Station-Grid （VEG） model is proposed for future electric vehicles （EVs）, and associated future business implementation is explored. The use of VEG enables the EV owners to have flexible choices. For example, they choose a slow charge process in their home garages or a fast charge route at an energy station equipped with low-cost, long-life MW scale battery energy storage units for a rapid charge service. In addition, the energy station can extract or deliver energy with the gird for peak and frequency regulations. For this model to work, development of the safe and fast-charging power battery and the low cost and long life storage battery is very essential.
