The transportation system is used for transporting the battery pack, and optionally, the transportation system transports the battery pack in a driving belt mode; optionally, the transportation system transports the battery pack in a rail-bound or trackless trolley manner. The battery pack is transported from an initial position to a target position at an initial speed during transportation, and stops when the battery pack reaches the target position. For the transfer of the battery pack in the battery replacement station, the initial speed of the battery pack at the initial position is zero, the battery pack needs to be accelerated to a certain speed when being transported to the target position, and the battery pack starts to decelerate when reaching the target position until stopping at the target position. Thus, a transport control scheme can be designed by controlling the battery pack transport speed. And the speed reduction station, namely the battery pack, starts to reduce speed when being transported to the position, and the target station, namely the target position for transferring the battery pack. In the replacing process, the battery pack is transported in the battery replacing station, and the target station can be a battery replacing platform or a cache bin 200 for storing the battery pack. The detection system is used for detecting the position of the battery pack in the transportation system, and consists of a plurality of sensors which can cover the whole battery pack transportation system and monitor the whole transportation process of the battery pack; the method can also be arranged at the speed control key node in the battery pack transportation system, such as the speed reduction station, the destination station and other positions, and when the detection system detects that the battery pack is transported to the corresponding position, the transportation system adopts the corresponding speed control strategy. Because the shell of the existing battery pack is mostly made of materials with electromagnetic induction, in order to ensure the detection precision of the detection system, the position of the battery pack can be monitored by an inductive sensor.
The detection system further comprises an offside sensor 303, and the offside sensor 303 is used for detecting whether the battery pack is located at the destination station.
In the embodiment of the application, the sensor of the detection system is arranged on a key control node in the battery pack transportation system. Under the normal condition, the speed of battery package when transporting to the purpose station is zero, and when the transportation system broke down, the speed of battery package when transporting to the purpose station probably was not zero, and the battery package can the off-normal condition, consequently in order to avoid the battery package potential safety hazard to appear, consequently sets up off-normal sensor 303 and detects whether the battery package is in the purpose station, and when off-normal sensor 303 detected the battery package and crossed the purpose station, the transportation system stopped the transportation immediately.
A standby destination station is also arranged in the transportation system, and a standby destination sensor 304 is arranged on the standby destination station.
In the embodiment of the application, when the target station is occupied or has a fault, the standby target station can be started to replace the target station with the fault, so that a sensor is also required to be arranged on the standby target station to monitor the transportation condition of the battery pack.
The inductive sensor includes at least one of an eddy current sensor, a mutual inductive sensor, and a self-inductive sensor.
In the embodiment of the application, the detection system comprises a plurality of sensors, and all the sensors adopt inductive sensors to ensure accurate detection of the position of the battery pack. The plurality of sensors may be the same type of sensor, or a plurality of types of sensors may be present at the same time.
The battery pack transferring system further comprises a control device, the transporting system and the detecting system are respectively connected with the control device, and the control device is used for controlling the battery pack to be transported in the transporting system according to detection signals of the detecting system.
In the embodiment of the application, the detection system feeds back a detection signal to the control device, and the control device controls the transportation system to work by adopting a corresponding control strategy according to the detection signal of the detection system.
