In one embodiment, at least one processor 1800 of the main body 1000 of the cordless vacuum cleaner 100 may check the type of at least one battery 1500 and whether the at least one battery 1500 is abnormal. At least one processor 1800 may control the maximum output mode based on the type of at least one battery 1500. For example, the at least one processor 1800 may set the output of the suction motor 1110 in the jet mode of the lightweight battery to be low compared to that of the performance battery.

In one embodiment, the at least one processor 1800 may operate in an abnormal mode, an overload mode, or a protection mode when the state of the at least one battery 1500 is abnormal. At least one processor 1800 may reduce the output of the suction motor 1110 in at least one operation mode, including a maximum output mode in an overload mode. For example, the at least one processor 1800 may reduce the output of the suction motor 1110 in the jet mode and the super power mode compared to the normal mode to protect the at least one battery 1500 in the overload mode. At least one processor 1800 may stop the output of the suction motor 1110 in at least one operation mode including a maximum output mode in a protection mode. For example, the at least one processor 1800 may stop the output of the suction motor 1110 in the jet mode and the super power mode rather than the normal mode to protect the at least one battery 1500 in the overload mode.

Hereinafter, the full charge voltage and end-discharge voltage of at least one battery 1500 according to the operation mode will be described with reference to FIG. 16.

FIG. 16 is a table showing the results of controlling at least one of the full charge voltage and end-of-discharge voltage of the battery 1500 according to the operation mode of the cordless vacuum cleaner 100 according to an embodiment of the present disclosure.

In one embodiment, at least one processor 1800 of the main body 1000 of the cordless cleaner 100 may check the operation mode of the cordless cleaner 100. For example, at least one processor 1800 may check whether the wireless vacuum cleaner 100 corresponds to an operation mode among jet mode, super-power mode, powerful mode, and normal mode. At least one processor 1800 may check the power consumed by the suction motor 1110 in the current operating mode of the wireless vacuum cleaner 100. At least one processor 1800 may check the usage time in the current operating mode of the wireless vacuum cleaner 100.

In one embodiment, the at least one processor 1800 may control at least one of the full charge voltage and the end-of-discharge voltage of the at least one battery 1500 based on the operation mode of the cordless vacuum cleaner 100. The full charge voltage may be the voltage when at least one battery 1500 is fully charged. The discharge end voltage may be a voltage at a cut-off point at which at least one battery 1500 stops outputting power. At least one processor 1800 may variably set the full charge voltage and end-discharge voltage of at least one battery 1500 to increase the lifespan and use time of the at least one battery 1500.

In one embodiment, the at least one processor 1800 may reduce the full charge voltage and increase the end-of-discharge voltage in the maximum output mode of the suction motor 1110. For example, when the wireless vacuum cleaner 100 is in jet mode, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to about 4.10 V and the end-discharge voltage to about 2.8 V. there is. In the jet mode, which is the maximum output mode of the suction motor 1110, the power supplied by at least one battery 1500 to the suction motor 1110 may be maximized to maximize the output power of the suction motor 1110. The maximum output mode of the suction motor 1110 may directly affect the lifespan of at least one battery 1500. Accordingly, the at least one processor 1800 controls the full charge voltage and end-discharge voltage of the at least one battery 1500 to consider improving the lifespan of the at least one battery 1500 when the cordless vacuum cleaner 100 is in the jet mode. can do.

In one embodiment, the at least one processor 1800 may increase the full charge voltage and decrease the end-of-discharge voltage when the suction motor 1110 is in an operation mode other than the maximum output mode. As the output of the suction motor 1110 decreases, the at least one processor 1800 may increase the full charge voltage and decrease the discharge end voltage. For example, when the wireless vacuum cleaner 100 is in the ultra-powerful mode, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to about 4.16V and the discharge end voltage to about 2.6V. there is. For example, when the wireless vacuum cleaner 100 is in the powerful mode, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to about 4.2V and the end-discharge voltage to about 2.6V. there is. For example, when the wireless vacuum cleaner 100 is in the normal mode, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to be about 4.2V and the discharge end voltage to be about 2.5V. there is. The cordless vacuum cleaner 100 may reduce the influence of the full charge voltage and end-of-discharge voltage on the lifespan of at least one battery 1500 in operation modes other than the maximum output mode. Accordingly, at least one processor 1800 may increase the full charge voltage and decrease the end-of-discharge voltage to improve the use time of the cordless vacuum cleaner 100 in operation modes other than the maximum output mode.

The cordless vacuum cleaner 100 according to an embodiment of this document may control at least one of the full charge voltage and end-discharge voltage of at least one battery 1500 depending on whether the operation mode is the maximum output mode or the remaining mode. At least one of the full charge voltage and end-of-discharge voltage of the at least one battery 1500 may be variably controlled to take into account both the lifespan of the at least one battery 1500 and the usage time of the cordless vacuum cleaner 100.

Hereinafter, a method of controlling power consumption according to the temperature of at least one battery 1500 will be described with reference to FIG. 17.

FIG. 17 is a table showing the results of controlling the output of the suction motor 1110 according to temperature information of the battery 1500 of the cordless vacuum cleaner 100 according to an embodiment of the present disclosure.

In one embodiment, the wireless vacuum cleaner 100 The main body 1000 may further include a temperature sensor 1547. The temperature sensor 1547 may obtain temperature information of at least one battery 1500. For example, the temperature sensor 1547 may be disposed adjacent to at least one battery 1500.

In one embodiment, at least one processor 1800 of the main body 1000 of the wireless cleaner 100 may control the temperature sensor 1547 to obtain temperature information of at least one battery 1500. At least one processor 1800 may control power consumption of the suction motor 1110 according to the heat generation level of the at least one battery 1500.

In one embodiment, the at least one processor 1800 may gradually reduce the output of the suction motor 1110 when the temperature information of the at least one battery 1500 is greater than or equal to the first threshold temperature. For example, when the temperature of at least one battery 1500 is 60°C or higher, power consumption can be reduced by 10%. For example, when the temperature of at least one battery 1500 is 65°C or higher, power consumption can be reduced by 30%. The at least one processor 1800 determines the lifespan of the at least one battery 1500 and the lifespan of the at least one battery 1500 above the first threshold temperature. The output of the suction motor 1110 may be gradually reduced considering the usage time.

In one embodiment, the at least one processor 1800 may stop driving the suction motor 1110 when the temperature information of the at least one battery 1500 is greater than or equal to the second critical temperature than the first critical temperature. For example, when the temperature of at least one battery 1500 is 70°C or higher, driving of the suction motor 1110 may be stopped. Excessive heat generation of at least one battery 1500 may directly affect the lifespan of at least one battery 1500. Accordingly, at least one processor 1800 may immediately stop driving the suction motor 1110 above the second critical temperature, considering safety and the lifespan of at least one battery 1500 first.

Hereinafter, a method of controlling the full charge voltage and end-of-discharge voltage of at least one battery 1500 according to the usage cycle of the at least one battery 1500 will be described with reference to FIG. 18.

FIG. 18 is a table showing the results of controlling at least one of the full charge voltage and end-of-discharge voltage of the battery 1500 according to the usage cycle of the cordless vacuum cleaner 100 according to an embodiment of the present disclosure.

In one embodiment, at least one processor 1800 of the main body 1000 of the wireless vacuum cleaner 100 may obtain a usage cycle of at least one battery 1500. A usage cycle may be the number of times that at least one battery 1500 reaches a fully charged state and/or a fully discharged state due to charging, use, and discharging of the at least one battery 1500 . For example, the at least one processor 1800 divides the use cycle of the at least one battery 1500 into 300 or less, 301 or more, 600 or less, 601 or more, 800 or less, and 801 or more. can do.

In one embodiment, the at least one processor 1800 reduces the full charge voltage of the at least one battery 1500 as the usage cycle of the at least one battery 1500 increases and determines the end of discharge of the at least one battery 1500. Voltage can be increased. The at least one processor 1800 considers the lifespan of the at least one battery 1500 and reduces the full charge voltage of the at least one battery 1500 as the usage cycle increases, and reduces the discharge end voltage of the at least one battery 1500. can increase. For example, when the usage cycle is 300 or less, the at least one processor 1800 controls the full charge voltage of the at least one battery 1500 to about 4.16V, and controls the end-of-discharge voltage of the at least one battery 1500 to about 4.16V. It can be controlled at 2.7V. For example, when the usage cycle is 301 to 600, the at least one processor 1800 controls the full charge voltage of the at least one battery 1500 to about 4.10 V, and stops discharging the at least one battery 1500. The voltage can be controlled to about 2.8V. For example, when the usage cycle is 601 to 800, the at least one processor 1800 controls the full charge voltage of the at least one battery 1500 to about 4.05V and stops the discharge of the at least one battery 1500. The voltage can be controlled to about 2.9V. For example, when the usage cycle is 801 or more, the at least one processor 1800 controls the full charge voltage of the at least one battery 1500 to about 4.00 V and the end-of-discharge voltage of the at least one battery 1500 to about 4.00 V. It can be controlled at 3.0V. Accordingly, the at least one processor 1800 can minimize or make up for a decrease in the lifespan of the at least one battery 1500 due to an increase in the usage cycle.

In one embodiment, the at least one processor 1800 reduces the full charge voltage of at least one battery 1500 in consideration of the usage cycle when the cordless vacuum cleaner 100 is used in the maximum output mode, and at least one battery (1500) 1500) can increase the discharge termination voltage. When the wireless vacuum cleaner 100 is used in maximum output mode, the lifespan of at least one battery 1500 may be greatly affected. Accordingly, the at least one processor 1800 controls the full charge voltage and end-of-discharge voltage to make up for the decrease in lifespan of the at least one battery 1500 by considering only the usage cycle in the maximum output mode, which greatly affects the lifespan. It can be done. For example, the at least one processor 1800 considers only the usage cycle when the wireless vacuum cleaner 100 is used in the jet mode with the highest output among the handy situations in which the wireless vacuum cleaner 100 is used alone, and processes the at least one battery 1500. ) can reduce the full charge voltage and increase the discharge end voltage of at least one battery 1500. The at least one processor 1800 may not consider a usage cycle in an operation mode that has a relatively small effect on the lifespan of the at least one battery 1500. Accordingly, the at least one processor 1800 can prevent the problem of the usage time of the at least one battery 1500 being unnecessarily reduced.
