Document Type and Number:
WIPO Patent Application WO/2023/206230
Kind Code:
A1
Abstract:
Embodiments of the present application provide a method and apparatus for detecting a state of a lock body, capable of detecting a state of a lock body in time, thereby ensuring the safety of a battery swapping process. The method for detecting a state of a lock body comprises: measuring a first voltage at a first end in a lock body circuit, the lock body circuit comprising a first branch and a second branch, and the first branch and the second branch being connected in parallel between the first end and a second end, wherein if a lock body is in an unlocked state, the lock body is communicated with the first branch and is disconnected from the second branch, if the lock body is in a locked state, the lock body is communicated with the second branch and is disconnected from the first branch, the resistance of the first branch is different from that of the second branch, the first end is communicated with a power supply, and the second end is grounded; and determining the state of the lock body according to the first voltage.
