The present application relates to a wireless power supply method, device, system and storage medium for an elevator car. Wherein, the wireless power supply method of the elevator car includes sending a first action command to the power-taking device when it is confirmed that the current charging condition is satisfied; the first action command is used to instruct the power-taking device to communicate with the power supply device installed at the elevator landing; wherein , the power-taking device is set outside the elevator car and connected to the energy storage device; when it is detected that the power-taking device has completed its action and the contact voltage remains stable, the current charging time, the current terminal voltage value and the rated voltage of the energy storage device are obtained. terminal voltage value; and adjust the charging mode of the energy storage device according to the current charging time, the current terminal voltage value and the rated terminal voltage value; when it is confirmed that the current power-off condition is met, a second action command is sent to the power-taking device, and the instruction The energy storage device stops charging; wherein, the second action instruction is used to instruct the power taking device to separate from the power supply device.
Description
technical field [0001] The present application relates to the technical field of elevators, in particular to a wireless power supply method, device, system and storage medium for elevator cars. Background technique [0002] The elevator car is a box structure that vertically transports passengers up and down. The electrical equipment of the elevator car usually includes displays, fans, lighting, air conditioners and other equipment. The power supply of the electric equipment of the car is generally realized in the following three ways: one is by hanging cables in the elevator shaft; the second is by erecting power supply wires on the shaft; The power supply device installs a power feeding component on each floor the elevator car passes through, and supplies power to the car load and battery in a non-contact manner when the car leveling floor is stationary. [0003] During the implementation process, the inventors found at least the following problems in the traditional tech...
