Hay mower driven by double battery packs

Abstract

The invention discloses a hay mower driven by double battery packs. The control problem of battery discharging of the hay mower driven by the double battery packs is solved. The hay mower driven by the double battery packs comprises a cutter disk and a motor used as a power device, the cutter disk is provided with a control circuit which comprises a microcontroller, on one hand, the microcontroller is connected with a motor to drive the control circuit to emit a driving control signal, on the other hand, the microcontroller is connected with a current detecting circuit to receive a current signal of the motor, the motor is powered by the first battery pack and the second battery pack which are in parallel connection, a first switch circuit is arranged between the first battery pack and the motor, a second switch circuit is arranged between the second battery pack and the motor, and the control end of the first switch circuit and the control end of the second switch circuit are connected to the microcontroller. The double battery packs are in parallel connection to provide power for the motor of the hay mower, power supply by one single battery pack can be achieved, power supply by the double battery packs can also be achieved, the power supply situation is adjusted according to actual needs, so that electric energy waste is reduced, and the demand for the power of the motor can be met.

Description

technical field [0001] The invention relates to a lawnmower, in particular to a lawnmower driven by double battery packs. Background technique [0002] The main components of the lawn mower mainly include a cutter head, an engine, a walking mechanism, a handrail and a control circuit part. In order to prolong the working time of battery-powered lawn mowers, a Chinese patent with a publication number of CN203120457U provides a double-pack lithium battery lawn mower. Two lithium battery packs are connected in series to provide power for the motor, which can increase the working time, but After the two sets of batteries are connected in series, the control is relatively simple, and the battery power supply cannot be adjusted according to actual needs. There is also a problem of waste when the two sets of batteries supply power at the same time. Contents of the invention [0003] The purpose of the present invention is to provide a lawn mower driven by double batteries, which...
