The invention relates to the technical field of electric automobiles, and discloses an electric automobile power supply system and a control method thereof. The system comprises a dual-power-supply device and a charging device, and the dual-power-supply device is adopted for supplying power to a driving motor of an electric automobile; the dual power supply device comprises a main power supply module, a standby power supply module and a power supply switching module. The charging device is provided with a charging compartment; a base with a plug is arranged between the standby power supply module and the power supply switching module to realize plug-in connection; the power supply switching module can control the main power supply module and the standby power supply module to switch powersupply endurance, the charging device is in the form of a charging wall, the standby power supply module can be exchanged with the fully charged standby power supply module when the charging wall carries out centralized charging and the standby power supply module runs out of power, endurance is achieved, and the system is not limited to urban traffic any more; high-speed running is not limited; acharging pile is not needed, a lot of land resources are saved, and the investment cost and transformation construction cost of the electric vehicle charging pile are greatly reduced.
本发明涉及电动汽车技术领域,公开了一种电动汽车供电系统及其控制方法,该系统包括双电源装置和充电装置,采用双电源装置给电动汽车的驱动电机供电;双电源装置包括有主电源模块、备用电源模块和电源切换模块;充电装置设置有充电隔间;备用电源模块与电源切换模块之间设有带插头的底座,实现插接式连接;电源切换模块可以控制主电源模块与备用电源模块切换供电续航,充电装置为充电墙形式,备用电源模块能够在充电墙集中充电,备用电源模块电量耗尽时可以与充满电的备用电源模块互换,解决续航能力,不再局限于城市交通,实现跑高速不受限制;不需要充电桩,节省大量土地资源,大大减少电动汽车充电桩投资成本和改造建设成本。
