Weilai power exchange means that electric vehicle users can replace the fully charged vehicle battery pack at the power exchange station. When the driver stops the vehicle at the designated position, click the power change stop button on the central control screen. At this time, the voice prompts "please pay attention to the rear of the car, don't step on the accelerator, turn and open the door." At this time, the vehicle automatically enters the power exchange platform without manual intervention, which is also the second generation power exchange station with AVP automatic parking technology.
From the technical principle, there is no essential difference with the power exchange mode once proposed by Tesla, but it is realized through different technical paths and costs.
Power exchange principle
Both Weilai and Tesla change electricity for C-end users, and both connect the battery and the car body with bolts. The difference is that Weilai has 10 special bolts. Tesla's public patent shows that there are 48 smaller bolts to fix the battery, both of which are from XYZ three-dimensional size, but Tesla is experimental and has not been used on a large scale.
Weilai calls this one of the core ways to replenish energy, which is widely used in the owner's side. According to the public information of Beiqi Dianjiao, the battery is fixed by a snap-in battery, that is, the battery is fixed from the XY dimension. Compared with the other two brands, Weilai has some business model innovations based on the power exchange model.
