The invention provides a vehicle discharging method, a vehicle, a charging and discharging pile, a device, equipment and a medium, and the method comprises the steps: transmitting the maximum voltage of a battery to the charging and discharging pile after the charging and discharging pile is connected and communicates with the charging and discharging pile, and receiving the support voltage transmitted by the charging and discharging pile; the battery is subjected to voltage reduction processing according to the supporting voltage to obtain initial discharging voltage of the battery, first ready information is sent to the charging and discharging pile, the first ready information is used for the charging and discharging pile to conduct discharging preparation according to the first ready information and send second ready information after completion, and after the second ready information sent by the charging and discharging pile is received, the second ready information is sent to the charging and discharging pile. Discharging allowing parameters are sent to the charging and discharging pile in real time, the discharging allowing parameters comprise the maximum discharging voltage and the maximum discharging current allowed by the battery, and the discharging allowing parameters are used for the charging and discharging pile to adjust the charging and discharging parameters of the charging and discharging pile so that the battery can be discharged to the charging and discharging pile; according to the invention, the function of discharging to the low-voltage pile is realized, so that reverse discharging is realized.

    本申请提供一种车辆放电方法、车辆、充放电桩、装置、设备及介质,该方法包括在与充放电桩连接并与充放电桩建立通信后,发送电池最高电压给充放电桩,接收充放电桩发送的支持电压,根据支持电压对电池进行降压处理得到电池的初始放电电压,发送第一就绪信息给充放电桩,第一就绪信息用于充放电桩根据第一就绪信息进行放电准备且完成后发送第二就绪信息,接收充放电桩发送的第二就绪信息后,实时发送放电允许参数给充放电桩,放电允许参数包括电池最大允许的最大放电电压和最大放电电流,放电允许参数用于充放电桩进行其充放电参数调整使电池向充放电桩放电;本申请实现了向低压电桩进行放电的功能,从而实现了反向放电。
