Abstract

The invention relates to the field of hay mowers and specifically relates to a method and device for charging control of a hay mower. The method comprises the steps that during automatic mowing of thehay mower, a current output current of a storage battery in the hay mower and/or working time of the storage battery are/is detected; a current voltage of the storage battery is detected; according to the current output current and/or working time of the storage battery, a returning voltage can be determined; whether the current voltage is smaller than or equal to the returning voltage is judged;and when the current voltage is smaller than or equal to the returning voltage, the hay mower can be controlled to return to charging. By the method and device provided by the invention, electric quantity use efficiency of the storage battery is increased greatly.

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...
