Core Viewpoint - The article discusses the launch of China's first mobile charging mothership project on the Beijing-Shanghai Expressway, aimed at addressing the charging difficulties faced by electric vehicle owners during peak travel times, particularly during holidays [2][4][12]. Group 1: Project Overview - The mobile charging mothership project is a collaboration between Jiangsu Provincial Transportation Department and Jiangsu Diala New Energy Technology Co., Ltd. [2] - It is designed to provide efficient and flexible charging services for electric vehicle owners on the busy Beijing-Shanghai Expressway [4]. Group 2: Technical Features - The mobile charging mothership can support simultaneous charging for 8 vehicles, with a total energy capacity of 3600 kWh, which is 20 times that of a standard mobile charging unit, sufficient for 100 electric vehicles [4] - Charging efficiency can reach up to 120 kW per gun, doubling the speed compared to conventional charging stations [5] - The system includes 8 heavy-duty truck battery packs that meet stringent safety standards and utilize an intelligent water cooling system for safe and efficient charging [6]. Group 3: Operational Flexibility - Each battery pack is connected to Jiangsu's electric vehicle charging supervision platform, allowing for flexible scheduling based on the usage patterns of fixed charging stations [7]. - The "building block" battery pack solution is versatile, suitable for various vehicle types and emergency power needs in different scenarios [8]. Group 4: Environmental Impact - The energy supplied by the mobile charging mothership is sourced from photovoltaic power and off-peak grid electricity, contributing to a reduction of 39 kg of CO2 emissions per charging session [9]. - If successful, the project may expand to the entire Beijing-Shanghai Expressway and 176 high-traffic service areas nationwide, promoting the freedom of travel for electric vehicle owners [9]. Group 5: Pricing and Accessibility - The charging prices at the mobile charging mothership will be aligned with those of fixed charging stations, ensuring fairness and transparency [11]. - The project aims to provide a new solution to the "charging congestion" issue experienced during peak travel times on highways [11].
