Multi-Circuit Energy Storage Layout for Lower Charging Power Demand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing power demands on energy storage apparatuses lead to higher costs for charging mechanisms, particularly for high-power systems, resulting in elevated usage costs.
Innovation Solution
The energy storage apparatus is designed with at least two mutually insulated input-output terminals and independent high-voltage circuits, allowing for flexible connection configurations such as series or parallel connections, and includes insulated busbar assemblies and offset busbar plates to reduce the risk of short circuits and simplify the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the power demand of the energy storage apparatus is increased to meet higher power requirements, then the power supply capability is improved, but the cost of charging mechanisms increases
Solution Approach 1:
The energy storage apparatus is divided into multiple independent high-voltage circuits, each with its own input-output terminal. This segmentation allows each circuit to be charged independently by separate charging mechanisms, enabling the system to meet high power demands through parallel operation of multiple lower-power charging mechanisms rather than requiring a single high-power charging mechanism.
2Adaptability or versatility
If multiple high-voltage circuits are connected in series or parallel to meet diverse power demands, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
Each high-voltage circuit is designed with independent input-output terminals that can function both as input terminals for charging and as output terminals for power delivery. This multi-functionality allows the same circuit configuration to serve multiple purposes, enabling diverse power demands to be met without requiring additional dedicated circuits for each function, thus reducing overall system complexity.
3Volume of moving object
If busbar assemblies are placed close together to reduce space, then the volume is reduced, but the risk of short circuit increases
Solution Approach 1:
An insulating separator is introduced as an intermediary component between adjacent busbar assemblies. This separator maintains electrical insulation between the busbars while allowing them to be positioned close together, thus reducing the overall apparatus volume without compromising the reliability and increasing the risk of short circuits.
