A charger and a control method are disclosed. A charger according to an embodiment of the present disclosure includes a transceiver configured to obtain, from a battery of a cleaner, temperature information of the battery, and a processor configured to apply power to the battery based on the temperature information transmitted from the transceiver, wherein the processor applies a pulse wave of a first period to the battery when the temperature of the battery is measured within a predetermined first section. Accordingly, even if the temperature of the battery is outside the charge allowance range due to the discharge of the battery built in the cleaner, the battery can be charged more quickly, thereby reducing the total time required for charging the battery.

Charger and control method thereof

Provided is a battery pack including a plurality of battery cells for generating electrical energy; a lead frame for electrically connecting the plurality of battery cells; a sensor for measuring a status of at least one of the plurality of battery cells; and a wiring member for connecting the sensor and at least one of the plurality of battery cells, wherein the wiring member includes a wiring portion; and a fuse portion having a width smaller than that of the wiring portion.

Battery pack

A vacuum may include a cleaner body including a suction motor for generating suction force, a suction part communicating with the cleaner body and suctioning air and dust, and a battery assembly for supplying a power to the suction motor. The battery assembly may include a battery unit, a battery terminal, a switch for connecting or disconnecting the battery unit and the battery terminal, and a battery case for accommodating the battery unit. The cleaner body may include a body supporting the battery assembly and a switching operation part for operating the switch when the battery assembly is mounted on the cleaner body.

Vacuum cleaner

The present invention relates to a vacuum cleaner. The vacuum cleaner of the present invention comprises: a cleaner body having a suction motor for generating suctioning force, and running in operating mode and charging mode; a suctioning part communicating with the cleaner body, for suctioning air and dust; a battery assembly capable of supplying power to the suction motor and having a plurality of battery packs; a controller for controlling the operation of the suction motor; a current regulating unit for regulating the current applied to the suction motor in a state in which the plurality of battery packs are serially connected; a first switching mechanism for serially connecting the plurality of battery packs; and a second switching mechanism for parallelly connecting the plurality of battery packs.

A vacuum cleaner, a battery assembly and a charging stand are provided. The battery assembly may include a plurality of battery cells, and a battery cover configured to support the plurality of battery cells. The battery cover may include a plurality of partition walls, and each of the plurality of partition walls forms a plurality of cell chambers that accommodate each of the plurality of battery cells, respectively, and at least a portion of the plurality of partition walls are spaced apart from each other to form at least one separation chamber.

Vacuum cleaner, battery assembly and charging stand

In order to accomplish a solution task of the present disclosure, a cleaner hand according to an embodiment of the present disclosure may include a pipe configured to transfer at least one of air, dust, and foreign matter to a drive unit that generates a suction force, a grip portion connected to the pipe, and formed to be gripped by a user, a sensor unit disposed in the grip portion to sense information related to whether or not the grip portion is gripped by the user, and a controller configured to control the drive unit based on the sensed information.

Vacuum cleaner and handle for a cleaner

A vacuum cleaner may include a cleaner body including a suction motor for generating suction force, a suction unit communicating with the cleaner body and suctioning air and dust, and a battery assembly for supplying power to the suction motor. The battery assembly may include a plurality of battery cells, an inner case including a plurality of cell cases having the plurality of battery cells respectively accommodated therein and spaced apart from each other, and an outer case having the inner case accommodated therein and including a flow hole in which air flows.
