AI Technical Summary
Technical Problem
Existing vehicle connection circuits with multiple batteries face challenges in addressing various short-circuit modes efficiently, leading to increased costs and structural complexity due to the need for multiple fuses.
Method used
A vehicle connection circuit design with a first, second, and third fuse placement strategy that minimizes the number of required fuses by positioning them on non-overlapping or partially overlapping paths, allowing separate disconnection of each path in case of a short-circuit.
Benefits of technology
This design effectively addresses multiple short-circuit modes with a reduced number of fuses, reducing costs and simplifying the structure while maintaining functionality.
