Qichacha APP shows, Recently, Xiaomi Automotive Technology Co., Ltd. published a patent for "vehicle-to-vehicle charging circuit, charging wiring harness, charging system and electric vehicle", the publication number is CN216783299U.
The patent diagram shows that both ends of the adapter cable are equipped with charging guns, which can be inserted into two cars to transfer the power from one car to the other.
This also means that Xiaomi cars will have external discharge capabilities. In fact, today, with the development of electrification in full swing, the function of external discharge has been widely used in a variety of pure electric and plug-in models.
The external discharge is roughly divided into two types: VtoV and VtoL.
Among them, VtoV (Vehicle to Vehicle) mode literally means car-to-car charging, which simply means that the power in one’s own car can be recharged to other cars to supplement power for other vehicles with insufficient power.
The other type of VtoL (Vehicle to Load) is the external power supply mode, which allows you to directly convert the electrical energy in the car into AC power and output it outward, directly charging electrical devices such as induction cookers, microwave ovens, and mobile phones.
The abstract shows that the vehicle-to-vehicle charging circuit is applied to the first electric vehicle including the first charging interface, and the vehicle-to-vehicle charging circuit includes a controller, a power supply circuit and a voltage detection circuit. Vehicle-to-vehicle charging can be carried out through one electric vehicle to another electric vehicle to be charged, without moving the electric vehicle to be charged to a charging pile for charging, which improves the flexibility of charging electric vehicles.
