For example, the Chinese patent document CN105283375A discloses a battery replacement system, which is the same as most of the existing chassis battery replacement systems for power stations, but the battery replacement system has the following defects: 1. When changing the chassis battery, the driver needs to stop the vehicle very accurately. Otherwise, it is difficult to align the battery pack, tool set (wrench, etc.) with the chassis of the car at the battery replacement station, which is difficult for novices who are not skilled enough to drive
2. Due to the precise positioning of the wheels, the same battery exchange system cannot serve two types of vehicles with different front and rear wheelbases. As a result, the automatic battery exchange station can only provide battery exchange services for specific types of vehicles, which is not universal

Embodiment Construction
[0045] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.
[0046] In the present invention, the touch sensor panel is firstly touched by the touch piece that is arranged on the chassis of the electric vehicle and has a certain positional relationship with the battery pack. The number of touch points and the relative coordinate position between the touch points) and the relative positional relationship between the battery pack of this type and the touch piece is also determined in advance (programmed into the controller in advance), so that the controller according to the touch The touch information formed by the contact element touching the sensor panel can determine the model and specific location of the battery pack on the chassis of the electric vehicle, thereby controlling the battery replacement mechanism to accurately move to the in...

The invention discloses an electric-car switching station and a battery replacement method. The electric-car switching station comprises a plurality of switching positions, each switching position comprises a positioning table higher than wheel driving road and an underground bin located under the wheel driving road, and the positioning table is located above the underground bin; a battery storagearea and a switching mechanism are arranged in the underground bin; an operation window for the switching mechanism to perform battery disassembling is arranged in the top of the positioning table, the operation window covers a touch sensor panel, the touch sensor panel is used for receiving touch of multiple telescopic touching pieces having definite location relationship with battery packs on an electric car chassis, a controller determines the model and location of a first battery pack on the electric car chassis according to touch information and controls a panel drive mechanism to drivethe touch sensor panel to move horizontally to open the operation window correspondingly, and the switching mechanism correspondingly moves to the previously-determined position of the first battery pack under the control of the controller to complete replacement of the battery packs.
Description
technical field [0001] The invention relates to the technical field of electric vehicle energy supply, in particular to an electric vehicle replacement station and a battery replacement method. Background technique [0002] In recent years, the electric vehicle market has shown explosive growth, and more and more traditional car manufacturers have joined the electric vehicle camp. With the further tightening of emission regulations, it has become inevitable for electric vehicles to replace traditional fuel vehicles. It should be noted that although hybrid vehicles (fuel-driven in some working conditions and electric drive in some working conditions) have achieved good market performance in recent years, they are not within the scope of the present invention. The electric vehicle described in the present invention refers to a pure electric vehicle. [0003] At present, the mass-produced electric vehicles in the market have a good reputation, such as Tesla Motors in the Unit...
