Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If stationary charging spots are built in parking lots, then charging function is provided, but reconstruction or construction costs are high
Solution Approach 1:
Instead of bringing charging facilities to vehicles (stationary charging spots), the patent inverts the approach by bringing the battery to the charging facility (mobile charging apparatus). The charging vehicle travels to a centralized battery distribution station to exchange batteries, eliminating the need for stationary charging spots and distribution network reconstruction.
Solution Approach 2:
The patent extracts the battery from the vehicle and handles it separately through a dedicated mobile charging apparatus. This separates the charging function from the vehicle and the distribution network, allowing battery replacement without impacting the power grid infrastructure.
2Productivity
If large use of charging spots is implemented, then more vehicles can be charged, but impact on distribution network increases
Solution Approach 1:
The battery is extracted from the vehicle and replaced with a fully charged one from the mobile charging apparatus. This transfers the charging load from the distribution network to the mobile charging vehicle's battery, eliminating peak load impacts on the grid while maintaining high charging capacity.
Solution Approach 2:
The mobile charging apparatus acts as an intermediary between the distribution network and the electric vehicle. It stores energy in its own battery and provides it to vehicles during peak demand periods, decoupling vehicle charging from immediate grid load and reducing harmful impacts on the distribution network.
3Ease of operation
If user drives to charging spot, then vehicle can be charged, but convenience is reduced
Solution Approach 1:
Instead of requiring the user to drive the vehicle to a stationary charging spot, the charging vehicle comes to the user's location. The mobile charging apparatus travels to the user's parking area and performs battery replacement on-site, inverting the traditional charging flow and significantly improving convenience while reducing time loss.
Data Source
AI summary
A method for charging an electric vehicle is provided. The method includes that a mobile charging apparatus transmits its own status information to a centralized battery distribution station; the centralized battery distribution station determines, according to the received status information, whether power of a battery of the mobile charging apparatus is less than a first threshold; if the power of the battery of the mobile charging apparatus is less than the first threshold, the battery of the mobile charging apparatus is processed so that the power of the battery of the mobile charging apparatus is greater than a second threshold, wherein the second threshold is greater than the first threshold; and if the power of the battery of the mobile charging apparatus is not less than the first threshold, the mobile charging apparatus charges the electric vehicle.
