Welding Power Source Controller Safety Logic for Battery Jump

The patent introduces an intermediary safety system consisting of current sensors and control logic that mediates between the welding power source and battery connectors. This intermediary detects current flow patterns and actively prevents welding power from reaching battery connectors by interrupting the circuit or alerting the operator, thus resolving the contradiction between maintaining welding functionality and preventing battery damage.

The patent implements a feedback mechanism where current sensors continuously monitor electrical current flow and provide real-time information to the control system. The control logic processes this feedback to determine whether current flow corresponds to welding operations or battery charging, and takes appropriate corrective action to prevent harmful power application to batteries, thereby eliminating the safety hazard while preserving welding productivity.

The patent makes the existing welding output connector universal by enabling it to serve dual purposes: welding operations and battery charging/jumping functions. The control logic intelligently determines the appropriate function based on detected current flow patterns, eliminating the need for separate dedicated battery connectors and contactors. This resolves the contradiction by maintaining battery protection through smart control while reducing device complexity and cost.

The system employs self-service intelligence through control logic that automatically detects the operational mode (welding vs. battery charging) by monitoring current flow characteristics. This self-detection and self-regulation capability eliminates the need for additional mechanical switching devices like contactors, as the system autonomously prevents harmful power application to batteries based on its own sensor data, thereby reducing complexity while maintaining protection.
