On-Board Device Priority Control During EV Battery Swapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During battery swapping in electric vehicles, users face boredom and discomfort due to the unavailability of on-board devices, as existing solutions do not allow for the continued use of comforting and entertainment devices when the battery level is low, necessitating a method to control these devices based on battery level and priority.
Innovation Solution
An on-board device control method that manages device power based on a low-voltage battery level and preset priorities, enabling first-priority devices always and allowing second- and third-priority devices to operate when the battery level is sufficient, while disabling them as the level drops, and providing prompt messages and different forms of battery swapping process information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If on-board devices are allowed to operate during battery swapping, then user comfort and entertainment are improved, but low-voltage battery power is consumed faster
Solution Approach 1:
The system dynamically changes the operational parameters of on-board devices based on battery level. When battery level is high, more devices can operate; when battery level drops, devices are sequentially disabled according to priority levels, transforming the fixed power supply state into a dynamic one that adapts to battery conditions
Solution Approach 2:
On-board devices are segmented into different priority levels (first priority, second priority, third priority). This segmentation allows the system to selectively power different device groups based on battery availability, ensuring critical devices remain operational while non-critical devices are disabled when power is limited
2Adaptability or versatility
If multiple on-board devices are enabled during battery swapping, then user entertainment and comfort are enhanced, but device control complexity increases
Solution Approach 1:
Device priority levels are predetermined and configured before battery swapping occurs. The system pre-establishes which devices belong to which priority level, so that during battery swapping, the control logic simply follows the pre-set hierarchy without requiring complex real-time decisions, thus reducing control complexity while maintaining high device availability

AI summary
The disclosure relates to the technical field of vehicle control, and particularly provides an on-board device control method, a computer device, a storage medium, and a vehicle, with a view to solving the problem of how to control an on-board device based on a low-voltage battery level during battery swapping of a vehicle. To this end, the method of the disclosure includes: obtaining a low-voltage battery level; controlling an on-board device based on the low-voltage battery level and a preset on-board device priority; obtaining battery swapping process information; and displaying the battery swapping process information by an on-board display device based on the low-voltage battery level. According to the disclosure, whether on-board devices having different priorities respond to switch-on instructions given by a user are controlled based on different low-voltage battery levels, so that battery control can be optimized, and the user experience is improved while energy is saved on. The battery swapping process information is displayed in different forms by a console screen, and rich prompt messages, user operation instruction information, etc. are displayed, which further improves the interaction experience of the user.
