电池驱动的电动汽车(EVS)被认为是遏制碳排放和应对全球变暖的有效解决方案。驾驶电动汽车的主要缺点之一是里程焦虑，它可以被定义为担心车辆由于缺乏充电而没有足够的里程到达目的地。正在探索车辆对车辆(V2V)充电作为缓解里程焦虑问题的解决方案。V2V充电允许两辆电动汽车共享充电，因此如果一辆电动汽车被困在远离充电站的地方，可以从另一辆电动汽车充电。人们已经研究了各种V2V充电器。研究发现，传统的充电器涉及多个能量转换阶段，降低了能量转换效率。本文介绍了一种非车载直流V2V充电器。它减少了功率转换阶段，同时免除了任何车载充电器的使用。为了实现车载直流V2V充电器，采用了双向DC-DC转换器。根据电动汽车电池的电压和充电状态，转换器在各种模式下运行。反过来，V2V充电以自动方式进行管理。对车载V2V充电器的运行模式和管理方案进行了探讨。
Battery-powered Electric Vehicles (EVs) are considered as an effective solution to curb carbon emissions and fight global warming. One of the main drawbacks in driving an EV is range anxiety, which can be defined as the fear of vehicle having insufficient range to reach its destination due to lack of charging. Vehicle-to-vehicle (V2V) charging is being explored as a solution to mitigate the range anxiety issue. V2V charging allows the sharing of charge between two EVs so that if an EV is stranded far from a charging station, it can be charged from another EV. Various V2V chargers have been studied. It has been found that the traditional chargers involve many power conversion stages, which reduces the efficiency in the energy exchange. In this paper, an off-board DC V2V charger is presented. It reduces the power conversion stages while dispensing with the use of any on-board charger. To implement the off-board DC V2V charger, a bidirectional DC-DC converter is adopted. The converter operates in various modes, depending upon voltage and state of charge of the EV batteries. In turn, the V2V charging is managed in an automatic way. Operation modes and management program of the off-board V2V charger are discussed in the paper.
