Vacuum Cleaner Power Control for Interchangeable Battery Capacity

The patent implements dynamic power adjustment that automatically adapts the motor power output to the detected battery capacity. When a high-capacity battery is detected, the system allows higher power consumption rates, enabling shorter operating cycles to be completed more quickly. This dynamic adaptation resolves the contradiction by making the tool weight less of a burden when longer duration is achieved, as the system optimizes power usage based on available energy reserves.

The system changes the operating parameters (power output, current draw) based on the detected battery capacity. By detecting battery properties and adjusting motor power accordingly, the system allows users to achieve longer operating durations with larger batteries while maintaining acceptable weight levels, as the power profile is optimized to match the energy available without unnecessarily increasing mechanical load.

The system dynamically adjusts motor power output based on real-time detection of battery capacity and charge state. When high-capacity batteries are detected, the system permits higher power consumption to achieve better cleaning performance. When lower capacity batteries are used, the system automatically reduces power consumption to match available energy reserves. This dynamic power management resolves the contradiction by allowing high productivity only when sufficient energy capacity is available.

The patent implements a feedback mechanism where the control unit continuously monitors battery properties (capacity, charge state) and adjusts motor power output accordingly. This closed-loop control ensures that energy consumption is optimized to match available battery capacity, allowing high productivity when appropriate batteries are installed while preventing excessive energy consumption when smaller batteries are used.

The detection unit serves multiple functions: it identifies battery capacity, determines charge state, and provides this information to the control unit for power regulation. By making the detection system multi-functional, the patent achieves high adaptability without proportionally increasing complexity. The same detection infrastructure supports multiple operational modes and battery types.

The system performs self-configuration by automatically detecting battery properties and adjusting operating parameters without user intervention. The control unit autonomously adapts power output based on detected battery characteristics, eliminating the need for manual settings or complex user interfaces. This self-service approach achieves high adaptability while keeping the user-facing complexity low.
