Referring to fig. 1, an embodiment of the present application provides a BMS power consumption control system. This BMS power consumption control system includes: a battery module 100, a BMS module 200, a host module 300, and a power module 400. The host module 300 is a main controller of a product to which the BMS power consumption control system is applied, and the battery module 100 is used to provide power to the product. The BMS module 200 is electrically connected to the battery module 100. The host module 300 is electrically connected to the BMS module 200, and is configured to receive a control command and generate a control signal according to the control command. The power module 400 is electrically connected to the host module 300 for providing activation power. Wherein the host module 300 is used to control the operating state of the BMS module 200 according to the control signal and the activation power. Specifically, the host module 300 is used for receiving a control instruction for controlling the product to be started or shut down by a user. When the control instruction indicates that the product is started, the host module 300 generates a corresponding start control signal, so as to control the activation power to activate the BMS module 200, and the BMS module 200 starts to work to protect the power safety of the product; when the control command indicates that the product is turned off, the host module 300 generates a corresponding turn-off control signal to control the disconnection of the BMS module 200 from the host module 300, so that the BMS module 200 cannot receive the activation power, and the BMS module 200 stops operating, thereby reducing the power consumption of the BMS module 200. It is understood that the battery module 100 includes a plurality of cells, and the plurality of cells are connected in series or in parallel.
The BMS power consumption control system according to the embodiment of the present application receives a control instruction sent by a user through the host module 300, and when the user sends a start instruction, the host module 300 controls the BMS module 200 to receive an activation power to control the BMS module 200 to start working; when the user transmits a turn-off command, the host module 300 is disconnected from the BMS module 200 such that the BMS module 200 cannot receive an activation power to control the BMS module 200 to stop operating. When the product does not work, the BMS module 200 is in a turned-off state, and the overall power consumption of the BMS module 200 and the product is reduced, thereby extending the service lives of the battery module 100 and the product.
Referring to fig. 2, in some embodiments, the BMS module 200 includes: a first master unit 210, a first conversion unit 220, and a control unit 230. The first main control unit 210 is electrically connected to the host module 300, and is configured to provide an electrical signal; one end of the first conversion unit 220 is electrically connected to the battery module 100, and the other end of the first conversion unit 220 is electrically connected to the first main control unit 210; the control unit 230 is electrically connected to the first main control unit 210, the first conversion unit 220, and the host module 300, respectively, for controlling the operating state of the BMS module 200 according to the electrical signal and the activation power. Specifically, the first main control unit 210 is a main controller of the BMS module 200, and the first converting unit 220 is configured to convert a power supply provided by the battery module 100 or other external power sources into a power supply signal of the first main control unit 210, for example: the first converting unit 220 includes an AFE (Active Front End) that supplies power to the first main control unit 210 through an LDO (Low Dropout Regulator). When a user sends a product start control instruction, the control unit 230 receives the active power of the power module 400, and the control unit 230 is enabled to be activated, so as to control the first conversion unit 220 to provide a power supply signal for the first main control power, so that the first main control unit 210 can provide a continuous pulse electrical signal OP _ MCU, and the BMS module 200 starts to operate according to the continuous pulse electrical signal OP _ MCU. When the user transmits a turn-off control command, the control unit 230 cannot receive the activation power, and at this time, the first converting unit 220 does not output a power supply signal, that is, the first main control unit 210 cannot provide a continuous pulse power signal, and the BMS module 220 stops operating, so as to reduce the power consumption of the BMS module 200.
Referring to fig. 3, in some embodiments, the control unit 230 includes: a first pressure control flow element Q1 and a second pressure control flow element Q2. The base of the first voltage-controlled current element Q1 is electrically connected to the host module 300 and the first main control unit 210, respectively, and the emitter of the first voltage-controlled current element Q1 is grounded; the gate of the second voltage-controlled current element Q2 is electrically connected to the collector of the first voltage-controlled current element Q1, the source of the second voltage-controlled current element Q2 is electrically connected to the host module 300, and the drain of the second voltage-controlled current element Q2 is electrically connected to the first converting unit 220. Specifically, the first voltage-current controlling element Q1 is an NPN transistor, the second voltage-current controlling element Q2 is a PMOS transistor, and the connection relationship between the other elements and each element included in the control unit 230 is shown in fig. 3. When the user sends a product start control command, the host module 300 sends the power-up signal provided by the power module to the first voltage-controlled current element Q1 to control the first voltage-controlled current element Q1 to be turned on, and the second voltage-controlled current element Q2 is also turned on, so that the first converting unit 220 provides a power supply signal to the first main control unit 210. The sustain pulse electrical signal OP _ MCU provided after the first main control unit 210 is powered on keeps the first voltage control element Q1 in a conductive state to control the BMS module to normally operate. When the user sends a product shutdown control command, the first voltage-controlled current element Q1 cannot receive the activation power, so that the first main control unit 210 cannot generate the continuous pulse electrical signal OP _ MCU, and thus the first voltage-controlled current element Q1 is open. At this time, the BMS module is turned off to stop operating, i.e., the power consumption of the BMS module becomes 0W, thereby reducing the overall power consumption of the system.
Referring again to fig. 2, in some embodiments, the host module 300 includes: a key unit 310, a second main control unit 320, and a third control flow element Q3. The key unit 310 is used for receiving a control instruction of a user; the second main control unit 320 is electrically connected to the key unit 310, and is configured to generate a control signal according to the control instruction; the gate of the third voltage control element Q3 is electrically connected to the second main control unit 320, the source of the third voltage control element Q3 is electrically connected to the power supply module 400, and the drain of the third voltage control element Q3 is electrically connected to the BMS module 200. Specifically, the user sends a control command through the key unit 310, and the second main control unit 320 generates a corresponding control signal according to the control command to control the on/off of the third control flow element Q3. When the user presses a key to transmit a product start control command, the second main control unit 320 generates a corresponding turn-on control signal to control the third voltage flow element Q3 to be turned on, so that the BMS module 200 receives an activation power to start operating. When the user presses a key to transmit a product turn-off control command, the second main control unit 320 generates a corresponding turn-off control signal to control the third voltage control element Q3 to be turned off, so that the BMS module 200 stops operating because it cannot receive an activation power, thereby reducing power consumption of the BMS module 200.
In some embodiments, the host module 300 further comprises: a second conversion unit 330. The second converting unit 330 is electrically connected to the power module 400 and the sources of the third voltage-controlled current element Q3, respectively. Specifically, the second conversion unit 330 converts the activation power supplied from the power module 400 into a pulse signal of +5V to activate the control unit 230. It is understood that the switching voltage of the second switching unit 330 can be adaptively set according to actual needs, but the switching voltage should satisfy the turn-on voltage requirement of the third voltage control flow element Q3.
In a specific embodiment, when the user presses the switch to send a product start control command, the control signal generated by the second main control unit controls the third control flow element to be conducted. The second conversion unit converts the activation power provided by the power module into a +5V pulse signal, the +5V pulse signal controls the first voltage control current element to be conducted, and the second voltage control current element is also conducted accordingly. After the control unit is activated by the +5V pulse signal, the first conversion unit is controlled to provide a power supply signal for the first main control unit, so that the first main control unit provides a continuous pulse electric signal OP _ MCU for the control unit, and the first voltage control element keeps a conducting state according to the pulse electric signal OP _ MCU, thereby controlling the normal work of the BMS module. When a user presses the switch to send a product closing control instruction, the control signal generated by the second main control unit controls the third pressure control flow element to be switched off. At this time, the +5V pulse signal converted by the second conversion unit cannot be transmitted to the control unit, and the first voltage control current element is turned off due to the absence of the active power supply, so that the first conversion unit cannot provide a power supply signal to the first main control unit, so that the BMS module stops working.
Referring to fig. 1, the present embodiment provides a vacuum cleaner. This dust catcher includes: a battery module 100, a BMS module 200, a host module 300, and a power module 400. The host module 300 is a main controller of the cleaner, and the battery module 100 is used for providing power supply for the cleaner. The BMS module 200 is electrically connected to the battery module 100. The host module 300 is electrically connected to the BMS module 200, and is configured to receive a control command and generate a control signal according to the control command. The power module 400 is electrically connected to the host module 300 for providing activation power. Wherein the host module 300 is used to control the operating state of the BMS module 200 according to the control signal and the activation power. Specifically, the host module 300 is used for receiving a control command for controlling the start or the stop of the dust collector by a user. When the control command indicates that the dust collector is started, the host module 300 generates a corresponding start control signal, so as to control and activate the power supply to activate the BMS module 200, and the BMS module 200 starts to work to protect the power safety of the dust collector; when the control command indicates that the cleaner is turned off, the host module 300 generates a corresponding turn-off control signal to control the disconnection of the BMS module 200 from the host module 300 such that the BMS module 200 cannot receive the activation power, and the BMS module 200 stops operating, thereby reducing the power consumption of the BMS module 200. It is understood that the battery module 100 includes a plurality of cells, and the plurality of cells are connected in series or in parallel.
The vacuum cleaner provided by the embodiment of the application receives a control command sent by a user through the host module 300, and when the user sends a starting command, the host module 300 controls the BMS module 200 to receive and activate a power supply so as to control the BMS module 200 to start working; when the user transmits a turn-off command, the host module 300 is disconnected from the BMS module 200 such that the BMS module 200 cannot receive an activation power to control the BMS module 200 to stop operating. When the dust collector does not work, the BMS module 200 is in a closed state, the overall power consumption of the BMS module 200 and the dust collector is reduced, and therefore the service lives of the battery module 100 and the dust collector are prolonged.
Referring to fig. 2, in some embodiments, the BMS module 200 includes: a first master unit 210, a first conversion unit 220, and a control unit 230. The first main control unit 210 is electrically connected to the host module 300, and is configured to provide an electrical signal; one end of the first conversion unit 220 is electrically connected to the battery module 100, and the other end of the first conversion unit 220 is electrically connected to the first main control unit 210; the control unit 230 is electrically connected to the first main control unit 210, the first conversion unit 220, and the host module 300, respectively, for controlling the operating state of the BMS module 200 according to the electrical signal and the activation power. Specifically, the first main control unit 210 is a main controller of the BMS module 200, and the first converting unit 220 is configured to convert a power supply provided by the battery module 100 or other external power sources into a power supply signal of the first main control unit 210, for example: the first converting unit 220 includes an AFE (Active Front End) that supplies power to the first main control unit 210 through an LDO (Low Dropout Regulator). When a user sends a cleaner start control instruction, the control unit 230 receives the active power of the power module 400, and the control unit 230 is enabled to be activated, so as to control the first converting unit 220 to provide a power supply signal for the first main control power, so that the first main control unit 210 can provide a continuous pulse electrical signal OP _ MCU, and the BMS module 200 starts to operate according to the continuous pulse electrical signal OP _ MCU. When the user transmits a turn-off control command, the control unit 230 cannot receive the activation power, and at this time, the first converting unit 220 does not output a power supply signal, that is, the first main control unit 210 cannot provide a continuous pulse power signal, and the BMS module 220 stops operating, so as to reduce the power consumption of the BMS module 200.
Referring to fig. 3, in some embodiments, the control unit 230 includes: a first pressure control flow element Q1 and a second pressure control flow element Q2. The base of the first voltage-controlled current element Q1 is electrically connected to the host module 300 and the first main control unit 210, respectively, and the emitter of the first voltage-controlled current element Q1 is grounded; the gate of the second voltage-controlled current element Q2 is electrically connected to the collector of the first voltage-controlled current element Q1, the source of the second voltage-controlled current element Q2 is electrically connected to the host module 300, and the drain of the second voltage-controlled current element Q2 is electrically connected to the first converting unit 220. Specifically, the first voltage-current controlling element Q1 is an NPN transistor, the second voltage-current controlling element Q2 is a PMOS transistor, and the connection relationship between the other elements and each element included in the control unit 230 is shown in fig. 3. When the user sends a vacuum cleaner start control command, the host module 300 sends the excitation power provided by the power module to the first controlled voltage-current element Q1 to control the first controlled voltage-current element Q1 to be turned on, and the second controlled voltage-current element Q2 is also turned on, so that the first converting unit 220 provides a power supply signal to the first main control unit 210. The sustain pulse electrical signal OP _ MCU provided after the first main control unit 210 is powered on keeps the first voltage control element Q1 in a conductive state to control the BMS module to normally operate. When the user sends a vacuum cleaner off control command, the first voltage control flow element Q1 cannot receive the activation power, so that the first main control unit 210 cannot generate the continuous pulse electrical signal OP _ MCU, and thus the first voltage control flow element Q1 is open. At this time, the BMS module is turned off to stop operating, i.e., the power consumption of the BMS module becomes 0W, thereby reducing the overall power consumption of the system.
Referring again to fig. 2, in some embodiments, the host module 300 includes: a key unit 310, a second main control unit 320, and a third control flow element Q3.

When the user presses a button to send a cleaner start control command, the second main control unit 320 generates a corresponding on control signal to control the third control flow element Q3 to be turned on, so that the BMS module 200 receives an activation power to start operating. When the user presses a button to send a cleaner turn-off control command, the second main control unit 320 generates a corresponding turn-off control signal to control the third control flow element Q3 to turn off, so that the BMS module 200 stops operating because it cannot receive an activation power, thereby reducing power consumption of the BMS module 200.
In some embodiments, the host module 300 further comprises: a second conversion unit 330. The second converting unit 330 is electrically connected to the power module 400 and the sources of the third voltage-controlled current element Q3, respectively. Specifically, the second conversion unit 330 converts the activation power supplied from the power module 400 into a pulse signal of +5V to activate the control unit 230. It is understood that the switching voltage of the second switching unit 330 can be adaptively set according to actual needs, but the switching voltage should satisfy the turn-on voltage requirement of the third voltage control flow element Q3.
Referring to fig. 2, in some specific embodiments, the host module 300 further includes: and a function unit electrically connected to the second main control unit 320.

When a user presses the switch to send a dust collector closing control instruction, the control signal generated by the second main control unit controls the third pressure control flow element to be switched off. At this time, the +5V pulse signal converted by the second conversion unit cannot be transmitted to the control unit, and the first voltage control current element is turned off due to the absence of the active power supply, so that the first conversion unit cannot provide a power supply signal to the first main control unit, so that the BMS module stops working.
The BMS power consumption control system and the dust collector provided by the embodiment of the application receive the control instruction of a user through the key unit, so that the working state of the BMS module follows the working state of the host module, namely, the host module controls the BMS module to normally work when the host module works; when the host module does not work, the BMS module is controlled to be turned off by the host module, so that the power consumption of the BMS module is changed into 0W when the host module does not work, the overall power consumption of the BMS module and the system is reduced, and the service lives of the dust collector and the battery module are prolonged.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
