A household energy storage system with a charging pile that includes stacked and electrically connected energy storage battery modules, a DC-DC converter for voltage conversion, and a plug-in charging mechanism, allowing for flexible installation and reduced space usage by stacking the charging pile directly on the battery modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a charging pile is installed in a household to meet electric vehicle charging demands, then the charging function is provided, but the occupied floor area increases and installation complexity increases
Solution Approach 1:
The charging pile is designed to be stacked directly on top of the energy storage battery modules, with the charging pile forming an integrated columnar structure. The first plug of the charging pile fits into the second plug base of the battery modules, creating a nested configuration where the charging pile is positioned within the vertical space above the battery modules, thereby utilizing vertical space rather than horizontal floor area.
Solution Approach 2:
The system transitions from a horizontal layout to a vertical stacking configuration. The charging pile and battery modules are arranged in the vertical dimension (upward stacking) rather than side-by-side horizontal arrangement. This dimensional change allows the charging function to be added without increasing the horizontal occupied floor area, as the charging pile occupies the vertical space above the battery modules.
2Adaptability or versatility
If a charging pile is installed in a household to meet electric vehicle charging demands, then the charging function is provided, but the installation process becomes more complex
Solution Approach 1:
The system is divided into modular components: energy storage battery modules and a charging pile. Each battery module contains standardized plugs and plug bases, and the charging pile has a corresponding first plug that fits into the second plug base. This segmentation into standardized modules simplifies installation, as users can stack the charging pile directly on the battery modules without complex wiring or structural assembly.
Solution Approach 2:
The energy storage battery modules serve multiple functions: they provide energy storage for household loads and simultaneously serve as the base platform for the charging pile. The standardized plug and plug base design enables the charging pile to be universally compatible with the battery modules, allowing a single charging pile to work with multiple battery module configurations without requiring custom installation procedures.
3Quantity of substance
If fixed electricity is allocated to each household for city electricity, then the electricity supply is controlled, but it is not possible to meet both normal electricity consumption and electric vehicle charging demands simultaneously
Solution Approach 1:
The system merges the energy storage function and electric vehicle charging function into a single integrated household energy storage system. The energy storage battery modules store electricity for household loads, and the same battery modules provide power to the charging pile for electric vehicle charging. This merging allows the household to utilize stored energy for both domestic consumption and vehicle charging, effectively doubling the utility of the stored electricity without requiring separate dedicated power supplies.
Solution Approach 2:
The energy storage battery modules are designed to serve multiple purposes: they function as power sources for household loads and simultaneously as power sources for the charging pile. The standardized electrical connections and plug interfaces enable the battery modules to universally support both household appliance operation and electric vehicle charging, allowing a single electricity allocation to serve dual functions.
