A kind of pool cleaning robot endurance stable pressure control method and pool cleaning robot

Abstract

This invention proposes a method for stabilizing the voltage and extending the operating range of a swimming pool cleaning robot, as well as the robot itself. The method includes: collecting the robot's operating parameters; determining the State of Charge (SOC), battery voltage constraints, and illumination conditions based on these parameters; controlling the photovoltaic power output according to the determination results; adaptively switching between multiple operating modes; switching the power supply to different load zones based on illumination conditions, supplying the core load with the lithium battery voltage regulator circuit and the auxiliary load with the photovoltaic branch; and performing closed-loop optimization and control of the entire robot. Using the existing photovoltaic and battery power supply architecture, without adding complex hardware, it achieves maximized photovoltaic utilization, stable voltage and speed operation, reduced battery loss, and optimal synergy between battery life and operating range under full illumination conditions.
