Innovation Solution
A detachable charging cable assembly is provided, allowing users to attach a suitable charging connector to a charger, ensuring compatibility with different electric vehicle models. The charging cable assembly includes a charging connector, a charging cable, and a cable connector that can be easily linked to the charger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed charging cable assembly is integrated into the charger, then the structure is simple and maintenance is easy, but the charging connector type is fixed and cannot accommodate different electric vehicle models
Solution Approach 1:
The charging cable assembly is segmented into a detachable connector portion and a cable portion. The connector can be separated from the charger body and replaced with different types as needed, while the main charger structure remains intact. This allows the system to support multiple charging connector types without redesigning the entire charger.
Solution Approach 2:
The charger is designed with a universal mounting interface that can accommodate different types of charging connectors. By providing a standardized connection mechanism, the same charger body can work with various connector types (e.g., Type 1, Type 2, CHAdeMO, CCS) through detachable cable assemblies.
2Power
If large-capacity charging cables are used, then the charging power is sufficient, but the cables become thick and heavy making maintenance difficult
Solution Approach 1:
The heavy-duty charging cable assembly is divided into modular sections that can be independently replaced. If a cable becomes damaged, only the affected segment needs to be replaced rather than the entire assembly, significantly reducing maintenance effort and cost while still supporting high power transmission.
Solution Approach 2:
The cable assembly is extracted as a separate, removable component from the charger body. This allows the cable to be independently handled, stored, and replaced without affecting the charger infrastructure. The cable can be easily disconnected and reconnected, making maintenance straightforward despite the high power capacity requirements.
