Embodiment 1

[0032] This embodiment provides a charging control method of a lawnmower, which can be used on the controller of the lawnmower, such as figure 1 As shown, the method includes:

[0033] Step S101 , during the automatic mowing process of the lawn mower, the current output current of the battery on the lawn mower and / or the working time of the battery are detected.

[0034] Step S102, detecting the current voltage of the storage battery.

[0035] In this embodiment, after the lawnmower starts the automatic lawn mowing program, and during the automatic lawn mowing process, the current output current and / or working time of the battery can be detected in real time, and the current voltage can be detected in real time.

[0036] Step S103, determining the return voltage according to the current output current and / or working time.

[0037] Step S104, judging whether the current voltage is less than or equal to the regression voltage.

[0038] Step S105, when the current voltage is l...

Embodiment 2

[0072] This embodiment provides a charge control device for a lawnmower, which can be used to implement the charge control method for a lawnmower according to Embodiment 1 of the present invention, such as figure 2 As shown, the device includes: a first detection unit 10 , a second detection unit 20 , a determination unit 30 , a judgment unit 40 and a control unit 50 .

[0073] The first detection unit 10 is used to detect the current output current of the storage battery on the lawn mower and / or the working time of the storage battery during the automatic mowing of the lawn mower; Recheck the output current and / or operating time on the lawnmower when the voltage returns;

[0074] The second detection unit 20 is used for the current voltage of the storage battery;

[0075] In this embodiment, after the lawn mower starts the automatic lawn mowing program, and during the automatic lawn mowing process, the current voltage and current output current of the battery can be detecte...

Embodiment 3

[0105] This embodiment provides a charging control circuit, such as image 3 As shown, the control circuit includes a micro control unit MCU, a voltage detection circuit VC, and a current detection circuit CS, wherein the voltage detection circuit VC is used to detect the voltage of the battery B, and the current detection circuit CS is used to detect the output current of the battery B. The micro control unit MCU in the embodiment is also used to control the driving circuit of the motor M (including the driving circuit D1 , the driving circuit D2 and the driving circuit D3 ).

[0106] Those skilled in the art should understand that the embodiments of the present invention may be provided as methods, systems, or computer program products. Accordingly, the present invention can take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a com...

Abstract

The invention relates to the field of lawnmowers, in particular to a charging control method and device for a lawnmower. Wherein, the method includes: during the automatic mowing process of the lawn mower, detecting the current output current of the battery on the lawn mower and / or the working time of the battery; detecting the current voltage of the battery; according to the current output current and / or The working time of the battery determines the return voltage; judges whether the current voltage is less than or equal to the return voltage; when the current voltage is less than or equal to the return voltage, controls the mower to return to charge. Through the invention, the power usage efficiency of the storage battery is greatly improved.

Description

technical field [0001] The invention relates to the field of lawnmowers, in particular to a charging control method and device for a lawnmower. Background technique [0002] With the development of urban construction and the improvement of people's awareness of environmental protection, the level of urban greening has become a standard to measure the development level of a city and the quality of people's life. In recent years, the number of green spaces in urban squares and living quarters has increased, and the workload for lawn maintenance has become increasingly heavy. People have begun to try to use electronic information technology to realize intelligent mowing methods. Various manufacturers have launched their own smart lawnmower products, and strive to find safer, simpler and more efficient methods of mowing grass under the premise of controlling costs, so as to provide users with more intelligent services. [0003] At present, some companies have developed smart la...
