Solution Overview
Problem
Charging piles for electric vehicles require human-computer interaction interfaces, which increase costs and are prone to failure due to exposure to open-air conditions, affecting durability and user experience.
Innovation Solution
Establish a near-field communication connection between the charging pile and the vehicle to transmit information to the vehicle's electronic device, enabling it to display a human-computer interaction interface, thereby eliminating the need for physical interaction with the charging pile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a physical interaction interface is provided in the charging pile, then human-computer interaction functionality is achieved, but the cost of the charging pile increases and the interface durability deteriorates due to exposure to open-air conditions
Solution Approach 1:
The patent projects the interaction interface from the charging pile to the user's electronic device (smartphone, tablet, or vehicle screen) through screen casting technology. The charging pile transmits interface data to the electronic device, which then displays and handles user interactions. This eliminates the need for a physical screen at the charging pile, reducing its cost and exposure to environmental damage while maintaining full interaction functionality.
Solution Approach 2:
The electronic device serves as an intermediary between the user and the charging pile. Instead of the user directly interacting with the charging pile's physical interface, the interaction is mediated through the user's electronic device, which receives data from the charging pile via near-field communication and displays the interface locally.
2Ease of operation
If a physical interaction interface is provided in the charging pile, then user interaction is enabled, but the complexity of the charging pile system increases
Solution Approach 1:
The interaction interface functionality is extracted from the charging pile system and transferred to the user's electronic device. The charging pile retains only the essential charging functions and data transmission capabilities, while the complex display and interaction handling are offloaded to the user's device, simplifying the charging pile's overall system complexity.
3Ease of manufacture
If screen casting is implemented to eliminate the physical interface, then charging pile cost is reduced, but near-field communication connection establishment is required
Solution Approach 1:
The system automatically establishes near-field communication connections and initiates screen casting without requiring manual configuration. The charging pile and electronic device automatically detect each other, establish communication channels, and begin interface projection, making the process transparent to the user while eliminating the need for physical interfaces.

AI summary
Provided are a screen casting method, a screen casting apparatus, an electronic device, and a storage medium, which belongs to the field of communication technologies. The method includes: establishing a near-field communication connection with a vehicle; and sending, when the near-field communication connection is successfully established, first information to an electronic device related to the vehicle, to cause the electronic device to display a first interface. The first interface is a human-computer interaction interface corresponding to the charging pile. According to the provided screen casting method, the charging pile is no longer required to provide the human-computer interaction interface. In this way, the cost of the charging pile is reduced, and the user experience is improved.
