Fig. 1 is a flowchart of a discharge control method of a portable air conditioner according to an embodiment of the present invention.

As shown in the figure, the invention provides a discharge control method for a portable air conditioner, which specifically comprises the following steps:

and S10, determining the electric quantity information in the energy storage device.

First, it should be noted that the main executing body of the control method for obtaining the discharge of the portable air conditioner in the present embodiment may be a controller in the air conditioner. Specifically, this controller can confirm the electric quantity information of battery among the energy memory, and can understand, the electric quantity information of battery among the energy memory can show through the display list, perhaps indicates through the sound, and wherein, the display list can show the percentage that the residual capacity accounts for, also can directly show the specific value of residual capacity, and also can directly indicate the percentage that the residual capacity accounts for or the specific value of residual capacity through the sound suggestion.

And S20, controlling the output voltage in the energy storage device according to the determined electric quantity information.

After the charge information in the energy storage device is determined, the controller may control the output voltage in the energy storage device according to the charge information. In this embodiment, the relationship between the power information and the output voltage in the energy storage device is a positive correlation, that is, the lower the power of the battery in the energy storage device displayed in the power information is, the smaller the output voltage in the energy storage device is; the higher the electric quantity of the battery in the energy storage device displayed in the electric quantity information is, the larger the output voltage in the energy storage device is. It is understood that the output voltage of the energy storage device has a maximum output voltage, that is, when the charge information exceeds a certain threshold, for example, 80%, the output voltage of the energy storage device is output at the maximum output voltage.

And S30, detecting the input voltage of the portable air conditioner.

Since the voltage output from the energy storage device may have a loss or other reasons during the input to the portable air conditioner connected thereto, the input voltage of the portable air conditioner is not the same as the output voltage of the energy storage device, and thus the embodiment also detects the input voltage of the portable air conditioner. Specifically, after the input voltage in the portable air conditioner is detected, a display table may be used for displaying, where the display table may directly display the current input voltage in the portable air conditioner, or after the controller in the portable air conditioner obtains the input voltage of the portable air conditioner, the controller in the portable air conditioner may directly perform corresponding control according to the voltage, without displaying the input voltage.

And S40, controlling the running frequency of the compressor in the portable air conditioner according to the detected input voltage in the portable air conditioner.

After detecting the input voltage in the portable air conditioner, the controller may control the operating frequency of the compressor in the portable air conditioner according to the input voltage, for example, when detecting that the input voltage in the portable air conditioner is low, the controller may control to reduce the operating frequency of the compressor, so as to reduce the input power of the air conditioner, and further reduce the discharge rate of the battery in the energy storage device. Thereby realized when battery electric quantity is lower, reduced the battery discharge rate, made the battery discharge more abundant, improved the utilization ratio of battery energy storage electric quantity, avoided the battery to take place the over-discharge condition simultaneously, can let portable air conditioner operation longer time simultaneously, promoted user experience.

In some embodiments of the present invention, as shown in fig. 6, in step S10, the determining the electric quantity information in the energy storage device may specifically include: and S601, detecting the voltage in the energy storage device, and determining the electric quantity information in the energy storage device according to the detected voltage.

In this embodiment, it can be understood that the voltages corresponding to different amounts of electricity of the battery in the energy storage device are different, such as when the amount of electricity of the battery in the energy storage device is larger, the voltage is also larger, for example, when the energy storage device is fully charged, the voltage may be 10 volts, and when the energy storage device is half charged, the voltage may be 5 volts. It should be noted that, the corresponding relationships between the voltages and the electric quantities of the energy storage devices of different types may be different, so in this embodiment, the corresponding relationship between the voltages and the electric quantity information in the energy storage device may be determined according to the types of the batteries in the energy storage device, then when the electric quantity information of the batteries in the energy storage device is determined, the voltages in the energy storage device may be detected first, and then after the voltages are detected, the electric quantity information in the energy storage device may be determined according to the corresponding relationships. It can be understood that the corresponding electric quantity information can be obtained by detecting the voltage in the energy storage device, and the electric quantity information in the energy storage device can be accurately and conveniently obtained.

In this embodiment, as shown in fig. 6, after the information of the electric quantity in the energy storage device is acquired, step S20 may be executed to control the output voltage in the energy storage device according to the determined information of the electric quantity; s30, detecting the input voltage in the portable air conditioner; and S40, controlling the running frequency of a compressor in the portable air conditioner according to the detected input voltage in the portable air conditioner.

It should be noted that, for the specific implementation of steps S20, S30, and S40 in this embodiment, reference may be made to the above embodiment, and details are not repeated here.

In some embodiments of the present invention, as shown in fig. 7, the step S20 of controlling the output voltage in the energy storage device according to the determined electric quantity information may include:

s701, the voltage in the energy storage device is greater than or equal to a first preset voltage threshold value V _T1 And controlling the energy storage device to output a first voltage V1.

First, as can be seen from fig. 5, the voltage of the energy storage device changes with the information of the electric quantity thereof, so if the electric quantity of the energy storage device is insufficient, the energy storage device is also controlled to output a higher voltage, which may easily cause an over-discharge condition of the energy storage device. Thus, in this embodiment, the voltage in the energy storage device is detected to be greater than or equal to the voltage threshold V _T1 At this time, it is indicated that the electric quantity in the energy storage device is still sufficient, and then the requirement of the load can be met first, that is, the energy storage device can be controlled to output the first voltage V1. It should be noted that the power information in this embodiment may be a battery voltage in the energy storage device, that is, in this embodiment, the energy storage device is powered according to the power informationThe output voltage in the energy storage device is controlled according to the voltage of the battery in the energy storage device.

S702, the voltage in the energy storage device is less than a first preset voltage threshold value V _T1 And is greater than or equal to a second preset voltage threshold V _T2 And controlling the energy storage device to output a second voltage V2, wherein the second voltage V2 is smaller than the first voltage V1.

In this embodiment, when it is detected that the voltage in the energy storage device is less than the voltage threshold V _T1 While the voltage in the energy storage device is also greater than or equal to a voltage threshold V _T2 If the energy storage device is controlled to output the first voltage V1, the working voltage is unstable, so the portable air conditioner cannot work well, and in this case, the energy storage device can be controlled to output the second voltage V2. It is understood that the second voltage V2 is smaller than the first voltage V1.

S703, the voltage in the energy storage device is less than a second preset voltage threshold value V _T2 And controlling the energy storage device to output a third voltage V3, wherein the third voltage V3 is smaller than the second voltage V2.

In this embodiment, if it is detected that the voltage in the energy storage device is less than the voltage threshold V _T2 If the energy storage device is controlled to output the second voltage V2, the energy storage device may be over-discharged, and even if the energy storage device is controlled to output the second voltage V2, the operating voltage is unstable, so the portable air conditioner may not operate well, and therefore, in this case, the energy storage device may be controlled to output the second voltage V3. It is understood that the second voltage V3 is smaller than the first voltage V2.

Optionally, in some specific embodiments, the first preset voltage threshold V _T1 May be 3.6 volts, a second predetermined voltage threshold V _T2 May be 3.2V, and, in this embodiment, as shown in fig. 9, when the energy storage device outputs the first voltage V1, its state may be a normal output state; when the energy storage device outputs the second voltage V2, the state thereof may be the voltage limit output state 1; when the energy storage device outputs the third voltage V3, the state thereof may be the voltage limit output state 2.

In this embodiment, as shown in fig. 8, if the energy storage device is charged in a situation where the energy storage device outputs the third voltage V3, controlling the output voltage in the energy storage device according to the determined electric quantity information may include:

s704, the voltage in the energy storage device is larger than a third preset voltage threshold value V _T3 And is less than or equal to a fourth predetermined voltage threshold V _T4 In the meantime, the energy storage device is controlled to output a second voltage V2, wherein, as shown in fig. 10, a third preset voltage threshold V is set _T3 Greater than a second predetermined voltage threshold V _T2 And is less than a first predetermined voltage threshold V _T1 Fourth predetermined voltage threshold V _T4 Greater than a first predetermined voltage threshold V _T1 . S705, the voltage in the energy storage device is greater than a fourth preset voltage threshold value V _T4 And controlling the energy storage device to output a first voltage V1.

Specifically, referring to fig. 8 and 9, when the energy storage device outputs the third voltage V3, it indicates that the current amount of electricity of the energy storage device is not much left, in some embodiments, a charging alert message may be sent, when the energy storage device is charged, the voltage in the energy storage device is still detected, and when it is detected that the voltage in the energy storage device is greater than the voltage threshold V _T3 And is less than or equal to the voltage threshold V _T4 In time, the energy storage device may be controlled to output the second voltage V2, and then the energy storage device enters the voltage limiting output state 1. When the energy storage device is in the voltage limiting output state 1, the energy storage device is continuously charged and detected, and if the voltage in the energy storage device is greater than the voltage threshold value V _T4 If so, the energy storage device is controlled to output the first voltage V1, so that the energy storage device enters a normal output state. It should be noted that the embodiment detects the storage in real timeThe electric quantity of the energy storage device can be set, the voltage output of the energy storage device can be switched in time, and the portable air conditioner can be ensured to obtain the optimal operation mode on the premise of reasonable output of the energy storage device

Optionally, in some specific embodiments, the third preset voltage threshold V _T3 Can be 3.3 volts, and a fourth preset voltage threshold V _T4 May be 3.7 volts.

In some embodiments of the invention, controlling the output voltage of the energy storage device may comprise: and adjusting the discharge multiplying power in the energy storage device, and further controlling the output voltage in the energy storage device.

Specifically, referring to fig. 5, different discharge multiplying factors respectively correspond to different discharge curves, and in a case that the electric quantity in the energy storage device is the same, the lower the discharge multiplying factor is, the higher the output voltage of the energy storage device is, so that the output voltage in the energy storage device can be controlled by adjusting the discharge multiplying factor in the energy storage device. It is understood that the output voltage in the energy storage device may be controlled by a charge and discharge control unit, which may be provided in the energy storage device.

In some embodiments of the present invention, as shown in fig. 11, wherein the step S40 of controlling the operating frequency of the compressor in the portable air conditioner according to the detected input voltage in the portable air conditioner may include:

s1101, the input voltage in the portable air conditioner is greater than or equal to a fifth preset voltage threshold value V _T5 And when the frequency is not controlled, the running frequency of the compressor is normally controlled.

Specifically, in the embodiment, the operation frequency of the compressor in the portable air conditioner is controlled by detecting the input voltage in the portable air conditioner, where the input voltage is greater than or equal to the voltage threshold V _T5 At this time, it is described that the input voltage of the portable air conditioner is sufficient for the compressor to normally operate, so that the compressor of the portable air conditioner can be controlled by giving priority to the demand of the load, that is, the operation frequency of the compressor in the portable air conditioner can be unlimited, as shown in fig. 12, the voltage in the portable air conditionerThe compressor is in a normal operation state.

S1102, the input voltage in the portable air conditioner is smaller than a fifth preset voltage threshold value V _T5 And is greater than or equal to a sixth preset voltage threshold V _T6 In the time, the compressor is controlled in a frequency limiting manner, so that the operating frequency of the compressor is less than or equal to the first limiting frequency F1.

Input voltage less than voltage threshold V in portable air conditioner _T5 And the voltage is greater than or equal to a voltage threshold V _T6 At this time, it is described that the input voltage in the portable air conditioner is small, and therefore, in order to make better use of the electric quantity in the energy storage device, the frequency-limited control needs to be performed on the portable air conditioner. Specifically, the portable air conditioner may be controlled to enter a frequency limiting state 1 in which the operating frequency of the compressor is less than or equal to the limiting frequency F1.

S1103, the input voltage in the portable air conditioner is less than the sixth preset voltage threshold V _T6 And in the time, controlling the compressor in a frequency limiting mode, so that the running frequency of the compressor is smaller than or equal to a second limiting frequency F2, wherein the second limiting frequency F2 is smaller than the first limiting frequency F1.

Input voltage less than voltage threshold V in portable air conditioner _T6 At this time, it is described that the input voltage in the portable air conditioner is already small, so in order to better utilize the electric quantity in the energy storage device, the frequency-limited control needs to be performed on the portable air conditioner. Specifically, the portable air conditioner may be controlled to enter the frequency limitation state 2 in which the operating frequency of the compressor is less than or equal to the limitation frequency F2.

In this embodiment, as shown in fig. 13, when the compressor is frequency-limited controlled such that the operating frequency in the compressor is less than or equal to the second limit frequency F2, the following steps are performed:

s1104, if the input voltage in the portable air conditioner is larger than the seventh preset voltage threshold V _T7 And is less than or equal to an eighth preset voltage threshold V _T8 In the meantime, the compressor is frequency-limited controlled so that the operating frequency of the compressor is less than or equal to a first limit frequency F1, whereinSeven preset voltage threshold values V _T7 Greater than a sixth predetermined voltage threshold V _T6 And is less than a fifth predetermined voltage threshold V _T5 Eighth preset voltage threshold V _T8 Greater than a fifth predetermined voltage threshold V _T5 。

In this embodiment, referring to fig. 13 and 12, when the compressor is in the frequency limiting state 2, it indicates that the current power of the energy storage device is insufficient, so that the user can be reminded to charge the energy storage device, and during the charging process of the energy storage device, the input voltage obtained by the portable air conditioner can be gradually increased, so that when the input voltage of the portable air conditioner is greater than the voltage threshold V _T7 And is less than or equal to a voltage threshold V _T8 Then the compressor can be controlled to switch to the frequency limitation state 1, so that the running frequency of the compressor is less than or equal to the limitation frequency F1. Note that, referring to FIG. 14, the voltage threshold V is _T7 Greater than a voltage threshold V _T6 And is less than a voltage threshold V _T5 Voltage threshold value V _T8 Greater than a voltage threshold V _T5 。

S1105, if the input voltage of the portable air conditioner is larger than the eighth preset voltage threshold V _T8 If so, the operating frequency of the compressor is normally controlled.

In this embodiment, referring to FIG. 12, during continued charging of the energy storage device, if it is detected that the input voltage in the portable air conditioner is greater than the voltage threshold V _T8 If so, it indicates that the current energy storage device has stored enough power, so that the compressor can be switched from the frequency limitation state 1 to the normal operation state, i.e. the operation frequency of the compressor can be normally controlled.

In addition, in the above embodiment, the output voltage V1 is greater than the voltage threshold V _T8 The output voltage V2 is less than the voltage threshold V _T5 And is greater than a voltage threshold V _T7 Voltage threshold value V _T6 Greater than the output voltage V3.

Further, as shown in fig. 16, the present invention provides a control device 200 for discharging a portable air conditioner, wherein the portable air conditioner is powered by an energy storage device, and the control device in this embodiment comprises: the determining module 201 is configured to determine information of an electric quantity in the energy storage device. And the first control module 202 is configured to control the output voltage in the energy storage device according to the determined electric quantity information. And the detection module 203 is used for detecting the input voltage in the portable air conditioner. And a second control module 204 for controlling the operating frequency of the compressor in the portable air conditioner according to the detected input voltage in the portable air conditioner.

Specifically, referring to fig. 16, the control apparatus 200 in this embodiment includes a determination module 201, a first control module 202, a detection module 203, and a second control module 204.

Wherein, the determination module 201 can determine the electric quantity information of the battery in the energy storage device, and can understand that the electric quantity information of the battery in the energy storage device can be displayed through the display list or prompted through sound, wherein the display list can display the percentage of the remaining electric quantity, also can directly display the specific value of the remaining electric quantity, and also can directly prompt the percentage of the remaining electric quantity or the specific value of the remaining electric quantity through sound prompting.

After the determination module 201 determines the power information in the energy storage device, the first control module 202 may be utilized to control the output voltage in the energy storage device according to the power information. In this embodiment, the relationship between the power information and the output voltage in the energy storage device is a positive correlation, that is, the lower the power of the battery in the energy storage device displayed in the power information is, the smaller the output voltage in the energy storage device is; the higher the amount of electricity of the battery in the energy storage device displayed in the electricity amount information is, the larger the output voltage in the energy storage device is. It is understood that the output voltage of the energy storage device has a maximum output voltage, that is, when the charge information exceeds a certain threshold, for example, 80%, the output voltage of the energy storage device is output at a maximum output voltage.

Since the voltage output from the energy storage device may have loss or other reasons during the process of inputting the portable air conditioner connected thereto, the input voltage of the portable air conditioner is not the same as the output voltage of the energy storage device, and therefore, the detection module 203 is further used in this embodiment to detect the input voltage of the portable air conditioner. Specifically, after the detection module 203 detects the input voltage of the portable air conditioner, a display table may be used for displaying, where the display table may directly display the current input voltage of the portable air conditioner, or after the controller in the portable air conditioner obtains the input voltage of the portable air conditioner, the controller in the portable air conditioner may directly perform corresponding control according to the voltage, without displaying the input voltage.

After the detection module 203 detects the input voltage of the portable air conditioner, the second control module 204 may be utilized to control the operating frequency of the compressor of the portable air conditioner according to the input voltage, for example, when the detection module 203 detects that the input voltage of the portable air conditioner is low, the control module 204 controls to reduce the operating frequency of the compressor, so as to reduce the input power of the air conditioner, and further reduce the discharge rate of the battery in the energy storage device.
