Problems solved by technology

At present, electric lawn mowers are mainly powered by a single battery pack. When one set of battery packs is fully discharged, the mowing work will stop and another set of battery packs will be replaced to continue working. This seriously affects the battery life of the lawn mower.
[0004] However, if multiple battery packs are used for power supply, the inconsistency of the battery packs will cause a decrease in the service life of the battery packs, resulting in attenuation of their performance.

Abstract

The invention discloses a riding type mower. The riding type mower comprises a plurality of battery packs, wherein the battery pack at least comprises a first battery pack and a second battery pack, and the rated voltage of the first battery pack is equal to that of the second battery pack; a power management module, which is set to obtain the voltages of the multiple accessed battery packs, and if the voltage of the first battery pack is smaller than that of the second battery pack and the voltage of the second battery pack is smaller than the rated voltage, during charging, the power management module can output a first control signal to control the first battery pack to be charged to a voltage equal to that of the second battery pack; when the voltage of the first battery pack is equal to that of the second battery pack, the power management module can output a second control signal to control the first battery pack and the second battery pack to be charged to preset voltage at the same time, and the preset voltage is smaller than or equal to rated voltage. By adopting the technical scheme, the service life of the battery pack can be prolonged.

Description

technical field [0001] The invention relates to a riding lawn mower and a charging method thereof. Background technique [0002] As a kind of landscaping machinery, electric lawn mowers are widely used in the pruning and finishing of green spaces such as urban street gardens, street green belts, and family courtyards. [0003] In the field of electric lawn mowers, lithium batteries have been more and more widely used because of their good performance. At present, electric lawn mowers are mainly powered by single battery packs. When one set of battery packs is fully discharged, the mowing work will stop and another set of battery packs will be replaced to continue working. This seriously affects the battery life of the lawn mower. [0004] However, if multiple battery packs are used for power supply, the inconsistency of the battery packs will lead to a decrease in the service life of the battery packs, resulting in attenuation of their performance.
