Technical Field

[0001] The present application relates to the technical field of battery packs, and in particular to a control method and device for a blowing assembly, a battery pack, and cleaning equipment. Background Art

[0002] Currently, battery packs in household appliances are easily affected by the temperature of the battery pack, which results in a longer charging time for the battery pack.

[0003] For example, the floor scrubbers on the market have a low charging current due to the hardware design of the charging pile and the limitations of the battery cell selection. On the other hand, the battery pack of the floor scrubber is affected by the internal resistance of the battery cell, as well as the motherboard or the real-time ambient temperature, which makes the temperature of the battery pack high and exceeds the rechargeable temperature range of the battery pack. Therefore, it has been in a false charging state, which leads to a long charging time. Summary of the Invention

[0004] In view of this, the embodiments of the present application provide a control method and device for a blowing assembly, a battery pack, and a cleaning device to solve the problem in the prior art that the battery pack temperature is high and thus the charging time is long.

[0016] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0017] The control method of the blowing assembly of the first aspect of the embodiment of the present application can obtain the real-time temperature of the battery pack when the battery pack is connected to a charging power source, and then control the blowing assembly to be turned on or off based on the real-time temperature, so that the blowing assembly can be controlled to be turned on and off according to the different temperatures of the battery pack to achieve the purpose of cooling when cooling is needed.

However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details.

[0039] Currently, the battery packs for floor scrubbers on the market often use six or more cylindrical cells or soft-pack cells in series to improve battery life or output higher peak currents to ensure the normal operation of high-power fans and motors. Because some cells do not have a multi-pole design, they have high internal resistance and a rapid temperature rise. To increase the energy density of the battery, some floor scrubbers also design the battery positive electrode material to have a higher compaction density. In some floor scrubbers, after users have used the battery for a period of time, the internal resistance also increases, causing the battery to heat up rapidly in high-temperature environments. Therefore, it is necessary to design a small fan on the battery pack casing to cool the battery.

[0040] However, the fan startup strategy of the battery pack of the floor scrubber is: the fan will only be turned on when the battery pack is discharged to the outside and the discharge current is greater than 1A. In other cases, the fan will not be turned on.

[0041] The control method, device, battery pack and cleaning equipment of the blowing assembly provided in this application are intended to solve the above technical problems of the prior art.

[0042] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments. It should be noted that the following embodiments can refer to, draw on, or combine with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0043] See also Figure 1 As shown, the present invention provides a schematic structural diagram of a battery pack 1. Figure 1 As shown, the battery pack 1 includes: a battery cell 11, a blowing assembly 12, and a control unit 13.

[0044] The control unit 13 is electrically connected to the blowing assembly 12 , and the control unit 13 is used to execute the steps of the control method of the blowing assembly 12 in the embodiment of the present application.

[0045] The battery pack 1 has its own software function, and the control unit 13 can directly control the opening and closing of the blowing component 12.

[0046] Optionally, the control unit 13 may also be electrically connected to the battery cell 11 , so that the control unit 13 can obtain relevant information of the battery cell 11 and detect the charging and discharging of the battery cell 11 .

[0047] Optionally, the battery pack 1 further includes an outer shell, within which the battery cells 11 are located, and a blower assembly 12 can be mounted on the outer shell. The blower assembly 12 can be a cooling fan or other blowing device, which cools the battery pack 1 by blowing air toward the battery cells 11. The battery pack 1 may also include a protective board (PCB), internal wiring harness, and nickel sheet.

[0048] An embodiment of the present application provides a cleaning device, including: a battery pack 1 according to an embodiment of the present application.

[0049] Among them, the cleaning equipment can be a floor scrubber. The embodiment of the present application takes the floor scrubber as an example, and other cleaning equipment with a battery pack 1 is also applicable.

[0050] Research has found that existing floor scrubber batteries are typically equipped with fans that only activate during discharge, not during charging. This means existing battery fans can only be activated in one way: by measuring the discharge current. However, in hot weather or when the floor scrubber has just completed a high-power discharge, with a battery temperature ≥50°C, if the floor scrubber is placed on a charging station and intended to charge while cleaning, the battery will appear to be charging, but in reality, it's only being charged at a low current. Low-current charging can only be resumed after the battery cools naturally and the temperature drops below 50°C, thus prolonging the charging time of the floor scrubber battery.

[0051] Based on the above analysis, an embodiment of the present application provides a control method for a blowing assembly 12 that can shorten or avoid the false charging state of the battery pack 1 by cooling the battery pack 1 when the battery pack 1 is connected to a charging power source, thereby shortening the charging time.

[0052] See also Figure 2 As shown, the embodiment of the present application provides a process of controlling a blowing component 12 Figure 1 Wherein, the blowing direction of the blowing component 12 is toward the battery cell 11 of the battery pack 1, and the control method of the blowing component 12 of the embodiment of the present application can be executed by the control unit 13 of the battery pack 1 of the embodiment of the present application. Figure 2 As shown, the control method of the blowing component 12 includes: step S201 to step S202.

[0053] S201 . When the battery pack 1 is connected to a charging power source, obtain the real-time temperature of the battery pack 1 .

[0054] Optionally, the real-time temperature of the battery pack 1 can be acquired by at least one first temperature sensor. The first temperature sensor can detect the temperature of the battery pack 1 in real time.

[0055] Specifically, if there is only one first temperature sensor, the temperature value detected by the first temperature sensor is the real-time temperature. If there are at least two first temperature sensors, the average of the temperature values of all first temperature sensors can be taken as the real-time temperature.

[0056] S202: Based on the real-time temperature, control the blowing component 12 to turn on or off.

[0057] The control method of the blowing assembly 12 of the embodiment of the present application can obtain the real-time temperature of the battery pack 1 when the battery pack 1 is connected to a charging power source, and then control the blowing assembly 12 to be turned on or off based on the real-time temperature, so that the blowing assembly 12 can be controlled to be turned on and off according to the different temperatures of the battery pack 1, so as to achieve the purpose of cooling when cooling is needed. Since the blowing direction of the blowing assembly 12 of the embodiment of the present application is toward the battery cell 11 of the battery pack 1, the embodiment of the present application can control the blowing assembly 12 to blow air toward the battery cell 11 based on the real-time temperature when the battery pack 1 is connected to a charging power source, thereby achieving the temperature of the battery pack 1 to be reduced to the chargeable temperature range as soon as possible, shortening or avoiding the false charging time of the battery pack 1, thereby shortening the charging time of the battery pack 1 and alleviating the user's anxiety while waiting for charging.

[0058] In some embodiments, the blowing assembly 12 is controlled to be turned on or off based on the real-time temperature, including: if the real-time temperature is not less than a first temperature threshold, the blowing assembly 12 is controlled to be turned on or off based on the state of charge SOC of the battery pack 1 .

[0059] The battery pack 1 enters a charging state when the real-time temperature is less than a first temperature threshold. The real-time temperature is measured by at least one first temperature sensor, which is provided in the battery cell 11 .

[0060] Specifically, when the battery pack 1 enters the charging state, a charging current can be generated to charge the battery pack 1 , and the battery pack 1 is no longer in a false charging state.

[0061] Optionally, if the real-time temperature is not less than the first temperature threshold, it indicates that the temperature of the battery pack 1 is high and needs to be cooled. In this case, it is necessary to further determine the state of charge (SOC) of the battery pack 1. The blower assembly 12 is only turned on when the SOC supports it, and otherwise remains off.

[0062] Optionally, the first temperature sensor is generally arranged at several points where the temperature inside the battery cells is the highest.

[0063] As an example, the first temperature threshold may be 50° C. When the temperature of the battery pack 1 is less than 50° C., the battery pack 1 is no longer in the false charging state and enters the charging state.

[0064] In some embodiments, based on the state of charge SOC of the battery pack 1, the blowing component 12 is controlled to be turned on or off, including: if the SOC is not less than a first preset threshold, the blowing component 12 is controlled to be turned on; if the SOC is less than the first preset threshold, the blowing component 12 is controlled to be turned off.

[0065] In the embodiment of the present application, whether the battery pack 1 can support the blowing component 12 to be turned on and blow air to the battery cell 11 to reduce the temperature of the battery pack 1 can be determined by judging whether the SOC is greater than a first preset threshold.

[0066] As an example, the first preset threshold may be 20%. When the SOC is ≥ 20%, the blowing assembly 12 may be controlled to be turned on.

[0067] In some embodiments, after controlling the blowing component 12 to turn on, the method further includes: if the real-time temperature is not greater than the second temperature threshold, controlling the blowing component 12 to turn off.

[0068] The second temperature threshold is lower than the first temperature threshold, and the battery pack 1 is charged with the target charging current when the real-time temperature is not higher than the second temperature threshold.

[0069] Optionally, the target charging current is the current of the battery pack 1 during normal charging.

[0070] As an example, the second temperature threshold may be 45° C. When the real-time temperature of the battery pack 1 is ≤ 45° C., the battery pack 1 may be charged with a normal current, and thus the blowing assembly 12 may be turned off.

[0071] In some embodiments, after controlling the blowing component 12 to be turned on, the method further includes: if the real-time temperature is greater than the second temperature threshold and less than the first temperature threshold, keeping the blowing component 12 turned on.

[0072] The battery pack 1 is charged with a first charging current when the real-time temperature is greater than the second temperature threshold and less than the first temperature threshold; the first charging current is less than the target charging current of the battery pack 1 .

[0073] In the embodiment of the present application, when the real-time temperature is greater than the second temperature threshold and less than the first temperature threshold, the battery pack 1 is controlled to charge at a low charging current while continuing to control the blowing component 12 to be turned on. Therefore, the embodiment of the present application can achieve a low current charging method at high temperatures while controlling the blowing component 12 to be turned on.

[0074] As an example, the first temperature threshold may be 50° C., and the second temperature threshold may be 45° C., then when 45° C. < real-time temperature < 50° C., the blowing component 12 may continue to be controlled to be turned on.

[0075] See also Figure 3 As shown, the embodiment of the present application provides a process of controlling a blowing component 12 Figure 2 The control method of the blowing assembly 12 of the embodiment of the present application can be executed by the control unit 13 of the battery pack 1 of the embodiment of the present application. Figure 3 As shown, the control method of the blowing component 12 of the embodiment of the present application includes: steps S301 to S310.

[0076] S301: The floor scrubber returns to the charging station. Battery pack 1 is connected to a charging power source, and the real-time temperature of battery pack 1 is obtained.

[0077] S302: Determine whether the real-time temperature is ≥ 50° C. If so, execute step S303; if not, execute step S301.

[0078] S303: Determine if SOC is greater than or equal to 20%. If so, proceed to step S305; if not, proceed to step S304.

[0079] S304: Natural cooling: The air blowing assembly 12 is turned off, and the battery pack 1 is cooled naturally.

[0080] S305 , turning on the air blowing assembly 12 . The air blowing assembly 12 is turned on to blow air to cool the battery pack 1 .

[0081] S306: Determine whether 45°C < real-time temperature < 50°C. If so, go to step S308; if not, go to step S307.

[0082] S307 , continue to turn on the blowing assembly 12 . Turn on the blowing assembly 12 to continue blowing air to cool the battery pack 1 .

[0083] S308: Turn on the blowing assembly 12 and charge with a first charging current. While blowing air to cool the battery pack 1, charge with a smaller current.

[0084] S309: Determine whether the real-time temperature is ≤ 45° C. If so, proceed to step S310; if not, proceed to step S308.

[0085] S310, turning off the blowing assembly 12 and charging with the target charging current.

[0086] See also Figure 3 As shown, in the embodiment of the present application, when the scrubber returns to the charging station and prepares to start charging, if the real-time temperature detected by the first temperature sensor NTC is ≥50°C, the SOC of the battery pack 1 is determined. When the SOC of the battery pack 1 is ≥20%, the blowing component 12 is immediately turned on to cool the battery. When the battery SOC is <20%, the battery pack 1 can only be cooled by natural cooling. At this time, the battery pack 1 is in a state of false charging and natural cooling.

[0087] When the real-time temperature drops below 50°C, battery pack 1 can resume low-current charging. Otherwise, battery pack 1 will continue to be used to cool the battery pack 1 until the real-time temperature drops. Charging can only be started when the real-time temperature is between 45°C < real-time temperature < 50°C. At this time, the real-time temperature only allows the battery to be charged with a low current. When the real-time temperature is ≤45°C, the battery can resume normal charging current and the blower assembly 12 is turned off.

[0088] See also Figure 4 As shown, the embodiment of the present application provides a process of controlling a blowing component 12 Figure 3 Wherein, the battery pack 1 is provided in the floor scrubber, and the control method of the blowing component 12 of the embodiment of the present application can be executed by the control unit 13 of the battery pack 1 of the embodiment of the present application. Figure 4 As shown, the control method of the blowing component 12 of the embodiment of the present application includes: step S401 to step S402.

[0089] S401 . When the floor scrubber is in a standby state, obtain the real-time temperature of the battery pack 1 and the real-time ambient temperature of the environment where the battery pack 1 is located.

[0090] Optionally, the real-time temperature of the battery pack 1 can be measured by a first temperature sensor, and the real-time ambient temperature of the environment where the battery pack 1 is located can be measured by a second temperature sensor. The measurement principle of the second temperature sensor is the same as that of the first temperature sensor.

[0091] S402: Based on the real-time temperature and the real-time ambient temperature, control the blowing component 12 to turn on or off.

[0092] In the embodiment of the present application, when the floor scrubber is in standby mode, in addition to the real-time temperature of the battery pack 1 , the real-time ambient temperature is also introduced to comprehensively consider whether it is necessary to control the blowing component 12 to be turned on.

[0093] In some embodiments, the blowing component 12 is controlled to be turned on or off based on the real-time temperature and the real-time ambient temperature, including: if the real-time temperature is not less than the third temperature threshold and the real-time ambient temperature is not less than the fourth temperature threshold, the blowing component 12 is controlled to be turned on.

[0094] Among them, the third temperature threshold is greater than the fourth temperature threshold, the real-time temperature is measured by at least one first temperature sensor, and the first temperature sensor is arranged in the battery cell 11; the real-time ambient temperature is measured by at least one second temperature sensor, and the second temperature sensor is arranged in the battery pack 1 or the floor scrubber.

[0095] Optionally, the third temperature threshold may be 40° C., and the fourth temperature threshold may be 30° C. The first temperature sensors are generally arranged at points where the internal temperatures of several battery cells are the highest.

[0096] Optionally, the second temperature sensor can be provided on the main board of the main unit of the floor scrubber to directly measure the real-time ambient temperature. The second temperature sensor can also be provided on the protection board inside the battery pack 1.

[0097] Specifically, when the floor scrubber is in the standby state, the floor scrubber is generally placed on the pile / base station and is being charged with sufficient power, so there is no need to judge the SOC of the battery pack 1.

[0098] In some embodiments, after controlling the blowing component 12 to turn on, the method further includes: if the real-time temperature is not greater than a fifth temperature threshold, controlling the blowing component 12 to turn off.

[0099] The fifth temperature threshold is smaller than the third temperature threshold and larger than the fourth temperature threshold.

[0100] Optionally, the fifth temperature threshold may be 35° C. When the real-time temperature is ≤35° C., the blowing assembly 12 may be controlled to be turned off, and the floor scrubber continues to be in the standby state.

[0101] See also Figure 5 As shown, the embodiment of the present application provides a process of controlling a blowing component 12 Figure 4 The control method of the blowing assembly 12 of the embodiment of the present application can be executed by the control unit 13 of the battery pack 1 of the embodiment of the present application. Figure 5 As shown, the control method of the blowing component 12 of the embodiment of the present application includes: steps S501 to S505.

[0102] S501: The floor scrubber is in a standby state. When the floor scrubber is in the standby state, the real-time temperature of the battery pack 1 and the real-time ambient temperature of the environment where the battery pack 1 is located can be obtained.

[0103] S502: Determine whether the real-time temperature is ≥ 40° C. If so, execute step 503; if not, execute step S501.

[0104] S503: Determine whether the real-time ambient temperature is ≥ 30° C. If so, execute step 504; if not, execute step S501.

[0105] S504 , turning on the air blowing component 12 . When the real-time temperature is ≥40° C. and the real-time ambient temperature is ≥30° C., the air blowing component 12 needs to be turned on to blow air to cool the battery pack 1 .

[0106] S505: Determine whether the real-time temperature is ≤35° C. If so, execute step 501; if not, execute step S504.

[0107] Specifically, when the real-time temperature is ≤35° C., the blowing assembly 12 can be turned off to allow the battery pack 1 to cool naturally.

[0108] See also Figure 5 As shown, in addition to charging the battery pack 1, the embodiment of the present application can also optimize the use strategy of the blowing component 12 when the floor scrubber is on standby. The optimized use strategy is: when the floor scrubber is on standby, when the real-time temperature T1 measured by the first temperature sensor NTC1 is ≥40°C, when the real-time ambient temperature measured by the second temperature sensor NTC2 or the real-time ambient temperature T2 measured by the host is ≥30°C, the battery pack 1 will turn on the blowing component 12 to help the battery pack 1 cool down, so as to improve the SOH (State of health) of the battery pack 1. SOH is used to indicate the ability of a battery to store electrical energy relative to a new battery.

[0109] When the blower assembly 12 is turned on and the temperature of the battery pack 1 drops below 35°C, the blower assembly 12 is turned off and the scrubber continues to standby. Otherwise, the blower assembly 12 continues to cool the battery pack 1. When the real-time ambient temperature T2 is less than 30°C, the battery pack 1 does not need to rely on the blower assembly 12 for cooling. The scrubber continues to standby and cools naturally.

[0110] See also Figure 6 As shown, the embodiment of the present application provides a process of controlling a blowing component 12 Figure 5 The control method of the blowing assembly 12 of the embodiment of the present application can be executed by the control unit 13 of the battery pack 1 of the embodiment of the present application. Figure 6 As shown, the control method of the blowing component 12 of the embodiment of the present application includes: step S601 to step S602.

[0111] S601 : When the battery pack 1 is in a discharging state, obtain the real-time discharge current and real-time temperature of the battery pack 1 .

[0112] Specifically, when the battery pack 1 is in a discharging state, the embodiment of the present application not only takes into account the magnitude of the real-time discharge current, but also the real-time temperature of the battery pack 1. That is, the embodiment of the present application also takes the real-time temperature into account during the discharge process, thus avoiding the conventional practice of directly turning on the blower assembly 12 only when the discharge current is ≥1A.

[0113] S602: Based on the real-time discharge current and the real-time temperature, control the blowing component 12 to turn on or off.

[0114] In some embodiments, the blowing assembly 12 is controlled to be turned on or off based on the real-time discharge current and the real-time temperature, including: if the real-time discharge current is not less than the preset discharge current, the blowing assembly 12 is controlled to be turned on; if the real-time discharge current is less than the preset discharge current and the real-time temperature is greater than the sixth preset temperature, the blowing assembly 12 is controlled to be turned on or off based on the SOC of the battery pack 1.

[0115] The real-time discharge current is detected based on the current detection module of the battery pack 1 , and the real-time temperature is measured by at least one first temperature sensor, which is provided in the battery cell 11 .

[0116] Optionally, the preset discharge current is 1A, and the sixth preset temperature is 55°C.

[0117] Optionally, the current detection module includes a fuel meter. The battery pack 1 of the floor scrubber generally has a fuel meter or other device inside, which can directly detect the size of the charging and discharging current.

[0118] In some embodiments, based on the SOC of the battery pack 1, the blowing component 12 is controlled to be turned on or off, including: if the SOC is not less than the first preset threshold, the blowing component 12 is controlled to be turned on; if the SOC is less than the first preset threshold, the blowing component 12 is controlled to be turned off.

[0119] In the embodiment of the present application, whether the battery pack 1 can support the blowing component 12 to be turned on and blow air to the battery cell 11 to reduce the temperature of the battery pack 1 can be determined by judging whether the SOC is greater than a first preset threshold.

[0120] In actual use, the battery pack 1 of a common floor scrubber may encounter the following problems during use:

[0121] (1) The battery pack 1 of the floor scrubber is waterproof and has strong sealing properties, but the natural heat dissipation is not very good. When the indoor temperature is high in summer or the PCB temperature is high, it will directly cause the battery temperature to rise.

[0122] (2) Some floor scrubbers have a built-in small fan in the battery pack 1 to dissipate heat from the battery, but the fan can only be turned on in discharge mode.

[0123] (3) The fan will only turn on when the discharge current is >1A.

[0124] In order to solve the above series of problems, the embodiment of the present application designs a battery pack 1 that can use the blowing component 12 during charging, discharging, and standby. In addition to solving the above problems, it can also improve the problems of the battery pack 1 of the floor scrubber, and at the same time improve the SOH of the battery pack 1 of the floor scrubber, thereby extending the battery life.

[0125] See also Figure 7 As shown, the embodiment of the present application provides a process of controlling a blowing component 12 Figure 6 The control method of the blowing assembly 12 of the embodiment of the present application can be executed by the control unit 13 of the battery pack 1 of the embodiment of the present application. Figure 7 As shown, the control method of the blowing component 12 of the embodiment of the present application includes: steps S701 to S706.

[0126] S701, the floor scrubber starts working.

[0127] S702: The battery pack 1 is discharged. When the battery pack 1 is in the discharge state, the real-time discharge current and the real-time temperature of the battery pack 1 are obtained.

[0128] S703: Determine whether the real-time discharge current is ≥ 1 A. If so, go to step 706; if not, go to step S704.

[0129] S704: Determine whether the real-time temperature is ≥ 55° C. If so, execute step 705; if not, execute step S702.

[0130] S705: Determine if SOC is greater than or equal to 20%. If so, go to step 706; if not, go to step S702.

[0131] S706 , turning on the air blowing component 12 . Turning on the air blowing component 12 , blows air to cool the battery pack 1 .

[0132] See also Figure 7 As shown, the embodiment of the present application provides a discharge mode for a floor scrubber. When the discharge current of the battery pack 1 is ≥1A, the blowing component 12 is directly turned on. When the discharge current is <1A, if the real-time temperature at this time is ≥55°C, in order to improve the SOH of the blowing component 12 and extend the service life of the battery, when the SOC of the battery is ≥20%, the blowing component 12 can also be directly turned on. When the SOC of the battery is <20%, the battery power is too low and the blowing component 12 cannot be turned on. When the battery temperature is <55°C, there is no need to use the blowing component 12 for heat dissipation, and the battery pack 1 can continue to discharge.

[0133] The embodiment of the present application can provide a more reasonable fan start-up strategy for the battery pack 1 of the floor scrubber. In addition to allowing the blowing component 12 to turn on the blowing component 12 after judging the discharge current of the battery pack 1 when the battery is discharging, the blowing component 12 can also be turned on when the battery pack 1 is charging, which reduces the probability of false charging of the battery and shortens the time waiting for the battery to be charged. In addition, when the floor scrubber is on standby, if the ambient temperature and the battery temperature are too high, the blowing component 12 can also be turned on by judging the real-time temperature and SOC of the battery and other conditions. Therefore, the embodiment of the present application provides a strategy for providing the blowing component 12 based on the different temperatures of the battery pack 1 in a variety of different scenarios, so that the cooling application of the blowing component 12 is more extensive and more practical.

[0134] Based on the technical solution of this application, the embodiments of this application provide a method for optimizing the activation of the blower assembly 12 of the battery pack 1 of a floor scrubber. This method can address issues such as the inability to use the blower assembly 12 during charging and standby mode, false charging of the battery pack 1, long charging times for the battery pack 1, and low charging current for the battery pack 1. Furthermore, the control method for the blower assembly 12 of the embodiments of this application can also improve the state of health (SOH) of the battery pack 1, thereby extending the life of the floor scrubber battery pack 1.
