Robot lawn mower and its battery detection method

Abstract

The invention discloses a robot lawnmower, which is used for automatically walking on the ground, mowing and returning to charge, which comprises: a casing, a cutting motor, a walking motor, a cutting part, a wheel set and a battery pack. It also includes a battery detection system electrically connected to the battery pack. The battery detection system includes: a detection module for detecting the state value of the battery pack after charging; a judgment module for reading the state value of the battery pack after charging , comparing the state value of the battery pack with a preset defined value; a prompting unit, when the state value of the battery pack reaches the preset defined value, the prompting unit gives a prompt. The detection module detects the battery status of the robot lawn mower, and the judging module judges whether the battery pack is aging or not, so that the battery pack can be replaced in time, and the mowing efficiency of the lawn mower will not be reduced due to the poor condition of the battery pack. The invention also discloses a method for detecting the battery of the robot mower.

Description

technical field [0001] The invention relates to a robot lawnmower, in particular to a robot lawnmower capable of battery performance detection. The invention also relates to a battery detection method of the robot mower. Background technique [0002] Now, the urban green area is rapidly expanding, and the green grass in the lawn grows very fast, so it must be taken care of and mowed in time. Because of the huge green area, lawn mowers are widely used in lawn cleaning. Due to the cumbersome and inconvenient operation of AC lawn mowers, rechargeable battery packs have been applied to lawn mowers. With the rapid development of battery technology, rechargeable lawn mowers are showing a trend of rapid development. The combination of battery technology and artificial intelligence technology has led to the emergence of battery-powered robotic lawnmowers, which can automatically walk on the ground, cut grass and return to charge. Rechargeable robotic lawnmowers have become a new t...

Problems solved by technology

[0003] However, after the rechargeable battery pack is repeatedly charged and discharged, the internal impedance of the battery increases, and the discharge capacity gradually degrades from its fully charged state. The work efficiency is high, and the battery pack needs to be replaced manually in time

However, manually replacing the battery pack cannot monitor the full charge of the battery pack in real time, which will lead to untimely battery replacement and affect the working efficiency of the lawn mower.
