The invention relates to the technical field of new energy vehicles, and discloses a new energy vehicle discharge method and system and a new energy vehicle, the method is applied to a power management module of the new energy vehicle discharge system, and the method comprises the following steps: when the connection with to-be-powered equipment is successful, obtaining resistance information of a current discharge resistor in the to-be-powered equipment; determining whether the resistance value of the current discharge resistor is a preset discharge resistance value according to the resistance value information; and if yes, switching on a switch between the power battery and the vehicle quick charging interface, so that the power battery discharges the to-be-powered equipment through the vehicle quick charging interface. When the resistance value of the current discharge resistor is determined to be the preset discharge resistance value, the switch between the power battery and the vehicle quick charge interface is directly closed to discharge the to-be-charged equipment, so that compared with the existing BMS which needs to finish the required steps according to the national standard charging process and then starts to discharge, the method can directly discharge, and the process is relatively simple and convenient.

    本发明涉及新能源汽车技术领域,公开了一种新能源汽车放电方法、系统及新能源汽车,该方法应用于新能源汽车放电系统的电源管理模块,该方法包括以下步骤:在与待用电设备连接成功时,获取待用电设备中当前放电电阻的阻值信息;根据阻值信息确定当前放电电阻的阻值是否为预设放电阻值;若是,则闭合动力电池与车辆快充接口之间的开关,以使动力电池通过车辆快充接口对待用电设备进行放电。由于本发明在确定当前放电电阻的阻值为预设放电阻值时,直接闭合动力电池与车辆快充接口之间的开关对待用电设备进行放电,相比于现有的BMS需要按照国标充电流程完成所需步骤之后开始放电,本发明可直接进行放电,流程较为简便。
