The invention discloses a method for direct current charging between electric vehicles, which comprises the following steps of: 1) publishing information including electric energy conditions of energy storage units of the electric vehicles running in a certain area range through a vehicle wireless communication technology to form an energy storage unit distribution map; (2) when the user finds that the electric energy of the user is insufficient, the information that the vehicle needs to be charged is published, and the vehicle cloud end sends the information of requesting to charge to the user of the electric vehicle with surplus electric energy reserve by calculating the electric energy condition of the energy storage unit of the vehicle traveling together; and (3) after the user capable of supplying power agrees, the two vehicles determine details of charging and stop in a direct-current charging mode between the vehicles, and charging of the target vehicle is achieved. The electric vehicles running in the same direction on the same road form an energy storage unit distribution map, the electric vehicles with surplus electric energy reserve can be automatically searched, communication connection is formed between the electric vehicles needing to be charged and unspecific power supply vehicles, and automatic searching and automatic matching can be achieved.

    本发明公开了一种电动汽车之间直流充电的方法,1)通过车用无线通信技术,将某一区域范围行驶的电动车的包括储能单元的电能情况在内的信息进行发布,构成储能单元分布地图;2)当用户发现自身电能不足时,将该车需要补电的信息发布,车云端经过计算同行的车辆的储能单元的电能情况,向具有富余电能储备的电动车用户发出请求补电的信息;3)在能供电的用户同意后,两车确定补电的细节,停下通过车辆之间直流充电方式,实现对目标车辆的补电。本发明将在同一道路上同向行驶的电动车形成一个储能单元分布地图,能自动寻找具有富余电能储备的电动车,在需要补电的电动车与不特定的供电车之间形成通信联系,能自动找寻、自动匹配。
