Disclosed is a battery unlocking control method, a battery locking control method and an electric vehicle battery swapping control method. The battery locking control method comprises the following steps: moving the battery to the fixing base to enable the lock shafts to enter the lock slots; after the lock shafts enter the lock slots, detecting the locations of the lock shafts, and moving the battery until the lock shafts arrive at locking locations; and with the lock tongues falling, snapping the lock shafts into the lock slots. By providing various location detection components, the battery is accurately located and locked when being loaded into a fixing base, and then accurately located and unlocked when being removed from the fixing base, thereby achieving full-automatic control during swapping of the battery and improving the swapping speed and success rate of the battery.

Battery locking/unlocking method, electric vehicle battery swapping control method

Disclosed is a battery swapping system, comprising a battery swapping device, a signal transmission unit, a position sensor, and a detection section. The battery swapping device comprises a master control unit and a battery pack disassembly and assembly unit. The battery pack disassembly and assembly unit is used for clamping the battery pack, the master control unit is used for controlling the battery pack disassembly and assembly unit to move along a preset path. The position sensor is used for generating a stopping instruction upon sensing of the detection section, sending the stopping instruction to the master control unit which is used for stopping moving the battery pack disassembly and assembly unit according to the stopping instruction. According to the present invention, whether a battery pack is mounted in place can be accurately detected, the accuracy and safety of battery pack swapping is ensured and the costs are low.

Battery swapping system with quick swapping support

Provided are a battery locking/unlocking system, and an electric vehicle battery swapping control system and a control method thereof. The battery locking/unlocking system comprises a battery swapping device used for moving a battery; a lock shaft detection unit used for generating a location signal; a lock tongue control unit used for controlling a lock tongue to fall into the lock slot or retract to the outside of the lock slot; a data exchange unit separately communicates with the battery swapping device and the lock shaft detection unit. According to the battery locking/unlocking system and locking and unlocking control methods, by providing various location detection components, the battery is accurately located and locked when being loaded into a fixing base, and then accurately located and unlocked when being removed, thereby achieving full-automatic control during swapping of the battery and improving the swapping speed and success rate of the battery.

Battery swapping system

A method for fabricating an NMOS transistor includes providing a substrate; forming a gate dielectric layer structure on the substrate and forming a gate electrode on the gate dielectric layer structure. The method further includes performing a fluorine ion implantation below the gate dielectric layer and an annealing process in an atmosphere comprising hydrogen or hydrogen plasma. The method also includes forming a source region and a drain region on both sides of the gate electrode before or after the fluorine ion implantation.
