As mobile platforms enter more industries (such as agriculture, electricity, and many special scene applications), the use of mobile platforms is more frequent. Take the drone as an example. The drone uses battery power, and the electrical energy output by the battery is used as the power supply and power source for the drone's flight control. When the battery of the drone is exhausted, the battery needs to be charged in time to ensure the continued use of the drone.

If the temperature of the drone’s battery is low, the drone’s battery will be heated until the temperature of the battery is not less than the preset value to stop heating, and then start to charge the battery. Charging the battery at this temperature can ensure battery life Charging efficiency.

When the battery power of the drone is insufficient, a charging device is needed to charge the battery to increase the power of the battery, and then provide sufficient power for the drone again to ensure the normal operation of the drone. Among them, drones basically work in an outdoor environment, and in most cases they work in the wild nature environment, so it is likely that the power is insufficient during the work in the wild nature environment, and it is necessary to promptly check in the current environment. The battery is charged to ensure that the drone can continue to work. When the ambient temperature in the wild nature environment is low, the charging performance of the battery should be ensured. The battery should be heated before charging to increase the battery's own temperature to the preset charging temperature, and then start charging the battery. However, the battery is currently in a low-temperature wild nature environment, and the temperature in this natural environment cannot be changed, and the low-temperature environment will cause the heat of the heated battery to dissipate, thereby causing the battery's own temperature to drop, which affects the charging of the battery. performance. Therefore, in order to ensure the charging performance of the battery when the temperature of the external environment of the battery cannot be changed, the battery's own temperature can be basically kept in a constant state during the battery charging process to prevent the battery's own temperature from falling to Preset charging temperature. Therefore, this application proposes a solution in which a heating device is used to intermittently heat the battery to offset the heat loss caused by the low-temperature external environment during the charging process of the battery using the charging device.

The upper side of one battery cell is in contact with the heating device, and the other battery cell The lower side of the core is in contact with the heating device.

Several specific embodiments are used below to introduce the solution of the present application in detail.

FIG. 5 is a flowchart of a battery heating method provided by an embodiment of this application. As shown in FIG. 5, the method of this embodiment can be applied to a charging device or a battery. The method of this embodiment may include:

S501. Obtain a first duty cycle during the charging of the battery by the charging device, where the first duty cycle is related to the ambient temperature of the environment in which the battery is located.

In this embodiment, in the process of charging the battery by the charging device, a duty cycle for controlling the heating device to intermittently heat the battery is obtained, and the duty cycle is referred to as the first duty cycle. And the first duty cycle is related to the ambient temperature of the environment where the battery is located. The ambient temperature of the environment where the battery is located is different, and the corresponding first duty cycle may also be different. For example, if the first duty cycle is 0.5, it can mean that there is a time duration of 0.5 seconds in each second that the heating device heats the battery, and the heating device does not heat the battery for another 0.5 seconds.

It can be understood that, in the process of charging the battery by the charging device, the first control signal may be obtained, and the first control signal includes the first duty cycle. The first control signal may also include other information, for example, the voltage and/or current for charging the battery, so as to charge the battery while heating the battery.

S502. Control the heating device to intermittently heat the battery according to the first duty cycle.

In this embodiment, after the first duty ratio is obtained, according to the first duty ratio, during the process of charging the battery by the charging device, the heating device is controlled to heat the battery intermittently, so that the battery is charged during the charging process. The battery's own temperature is basically constant.

The method of this embodiment can be applied to a charging device. If the heating device is provided in the battery, the charging device controls the heating device of the battery to intermittently heat the battery. If the heating device is provided in the charging device, the charging device controls the heating device of the charging device to intermittently heat the battery.

The method of this embodiment can be applied to a battery. If the heating device is provided in the battery, the battery controls the heating device of the battery to heat the battery intermittently. If the heating device is provided in the charging device, the battery controls the heating device of the charging device to intermittently heat the battery.

In this embodiment, the first duty cycle is obtained during the process of charging the battery by the charging device, and the first duty cycle is related to the ambient temperature of the environment where the battery is located; and according to the first duty cycle Than, controlling the heating device to intermittently heat the battery. By intermittently heating the battery during the charging of the battery by the charging device, the battery's own heat loss caused by the low-temperature environment of the battery is compensated to ensure that the battery's own temperature remains basically constant during the charging process, not due to the battery's own temperature The charging process of the battery is interrupted to ensure that the battery is in a continuous charging state, the charging efficiency of the battery is improved, and the service life of the battery is increased.

In some embodiments, the larger the first duty cycle, the longer the continuous heating time during the intermittent heating of the battery by the heating device. Take an intermittent heating time of 1 second as an example. For example, the first duty cycle is 0.5, which means that the duration of continuous heating in each second is 0.5 seconds, and the heating device stops heating the battery for another 0.5 seconds; for example, the first duty cycle is 0.2 means that the duration of continuous heating in each second is 0.2 seconds, and the heating device stops heating the battery for another 0.8 seconds. This also means that the larger the first duty cycle, the more heat the battery gets during the charging process.

In some embodiments, the first duty cycle is negatively related to the ambient temperature. The lower the ambient temperature of the environment where the battery is located, the greater the heat loss of the battery will be caused by the environment. Therefore, the larger the first duty cycle, the more heat the battery can obtain through the heating device, which should be as equal as possible to the heat loss. Ensure that the battery's own temperature is constant.

Based on the embodiment shown in FIG. 5, FIG. 6 is a flowchart of a battery heating method provided by another embodiment of this application. As shown in FIG. 6, the method of this embodiment can be applied to a charging device or For batteries, the method of this embodiment may include:

S601. In the process of charging the battery by the charging device, obtain the ambient temperature of the environment where the battery is located.

In this embodiment, during the process of charging the battery by the charging device, the ambient temperature of the environment where the battery is located is obtained.

Wherein, a temperature detection device can be provided in the battery, and the temperature detection device can detect the temperature of the battery itself.

Wherein, a temperature detection device may be provided in the charging device, and the temperature detection device can detect the temperature of the charging device itself.

If the method in this embodiment is applied to a charging device, the foregoing S601 may have the following two implementation modes:

In the first possible implementation manner, the battery's own temperature obtained from the battery when the charging device establishes a connection with the battery is the ambient temperature. Among them, when the charging device and the battery are connected, the charging device and the battery can communicate with each other. The battery can obtain the battery's own temperature detected by the battery's temperature detection device, and pass the battery's own temperature through the battery and the charging device. The communication signal is sent to the charging device. Since the charging device has not started to charge the battery when the charging device is connected to the battery, the battery's own temperature has not been affected by the heat generated during the charging process, and the heating device has not begun to heat the electricity, and the battery's own temperature has not yet been affected. The heating device generates heat, so the battery's own temperature at this time is close to the ambient temperature of the environment where the battery is located. Therefore, the charging device can determine the battery's own temperature when the charging device is connected to the battery as the ambient temperature.

In the second possible implementation manner, the temperature detection device of the charging device can detect the temperature of the charging device. Since the charging device and the battery are in the same environment, the charging device can detect the temperature of the charging device detected by the temperature detection device. Determine the ambient temperature of the environment where the battery is located. Optionally, in order to avoid the influence of the charging device on the heat generated during the charging of the battery, this embodiment may determine the temperature of the charging device detected by the temperature detecting device of the charging device when the charging device is connected to the battery as the ambient temperature.

If the method in this embodiment is applied to a battery, the foregoing S601 may have the following two implementation modes:

In the first possible implementation manner, the temperature detection device of the battery detects the temperature of the battery when the charging device establishes a connection with the battery. Since the charging device has not started to charge the battery when the charging device is connected to the battery, the battery's own temperature has not been affected by the heat generated during the charging process, and the heating device has not begun to heat the electricity, and the battery's own temperature has not yet been affected. The heating device generates heat, so the battery's own temperature at this time is close to the ambient temperature of the environment where the battery is located. Therefore, the battery can determine the battery's own temperature when the charging device is connected to the battery as the ambient temperature.

In a second possible implementation manner, the temperature detection device of the charging device can detect the own temperature of the charging device, and the charging device can send the own temperature of the charging device detected by the temperature detection device to the battery. Since the charging device and the battery are in the same environment, the battery can determine the temperature of the charging device as the ambient temperature of the environment where the battery is located. Optionally, in order to avoid the influence of the charging device on the heat generated during the charging of the battery, this embodiment may determine the temperature of the charging device obtained from the charging device when the charging device is connected to the battery as the ambient temperature.

S602. Determine a first duty cycle according to the ambient temperature.

In this embodiment, after obtaining the ambient temperature of the environment where the battery is located, according to the ambient temperature, the duty cycle used to control the heating device to intermittently heat the battery is determined, which is called the first duty cycle.

The following uses several specific implementation manners to introduce the above S602 in detail.

In a specific implementation manner, the first duty ratio is determined according to the preset charging temperature of the battery and the aforementioned ambient temperature. Among them, the first duty cycle is positively correlated with the preset charging temperature. The higher the preset charging temperature is, in order to maintain the battery's own temperature basically constant at the preset charging temperature during the charging device charging the battery, more heat needs to be compensated for the battery, so the larger the first duty cycle is, so that The longer the continuous heating time during the gap heating of the heating device. Thus, high-temperature charging of the battery can be realized, the polarization of the battery cell can be reduced, the charging current of the battery can be increased, and the purpose of fast charging can be achieved.

If the method in this embodiment is applied to a battery, the preset charging temperature may be stored locally in the battery in advance. If the method of this embodiment is applied to a charging device, after the charging device is connected to the battery, the battery can send the preset charging temperature of the battery to the charging device through the communication signal between the charging device and the battery. Correspondingly, before obtaining the first duty cycle, the charging device obtains the preset charging temperature of the battery from the battery.

In another specific implementation manner, the first duty ratio is determined according to the battery's own temperature and the above-mentioned ambient temperature in the process of charging the battery by the charging device. Among them, the first duty cycle is negatively related to the battery's own temperature. In the process of charging the battery by the charging device, the battery's own temperature will also change. If the battery's own temperature is lower, in order to maintain the battery's own temperature basically constant during the charging of the battery by the charging device, the battery needs to be compensated More heat, so the larger the first duty cycle, the longer the continuous heating time during the gap heating of the heating device. Therefore, it is possible to dynamically adjust the first duty cycle according to the battery's own temperature, so that the battery's own temperature is basically constant after intermittent heating, saving energy and avoiding overheating.

If the method of this embodiment is applied to a battery, the battery's own temperature can be detected by the battery's temperature detection device. If the method of this embodiment is applied to a charging device, the battery will send the battery's own temperature to the charging device after acquiring the battery's own temperature detected by the battery's temperature detecting device during the charging of the battery by the charging device. Correspondingly, the charging device obtains the battery's own temperature from the battery when the charging device charges the battery.

In another specific implementation manner, the first duty ratio is determined according to the battery's own temperature, the aforementioned ambient temperature, and the preset charging temperature of the battery during the charging of the battery by the charging device. It can not only realize high-temperature charging, but also save energy and avoid overheating.

Based on any of the foregoing implementation manners, optionally, if the ambient temperature is greater than or equal to the preset charging temperature of the battery, the determined first duty cycle is, for example, zero.

S603. Control a heating device to intermittently heat the battery according to the first duty cycle.

If the method of this embodiment is applied to a charging device, the charging device controls the electrical connection between the charging device and the heating device to be intermittently conducted according to the first duty ratio. When the electrical connection between the charging device and the heating device is conducted, the heating device obtains electrical energy to make the heating device work. The heating device generates heat during the working process, and the generated heat is used to heat the battery. Optionally, when the charging device is electrically connected to the heating device, the charging device controls the charging device to output current to the heating device, so that the heating device generates heat. Among them, the larger the current output by the charging device to the heating device, the more heat generated by the heating device; the smaller the current output by the charging device to the heating device, the less heat generated by the heating device.

If the method of this embodiment is applied to a battery, the battery controls the electrical connection between the battery cell group and the heating device to conduct intermittently according to the first duty ratio. When the electric core group and the heating device are electrically connected and conducted, the heating device obtains electric energy to make the heating device work, and the heating device generates heat during the working process, and the generated heat is used to heat the battery. Optionally, when the battery pack is electrically connected to the heating device, the battery controls the battery pack to output current to the heating device, so that the heating device generates heat. Among them, the larger the current output by the battery cell group to the heating device, the more heat the heating device generates; the smaller the current output by the battery cell group to the heating device, the less heat the heating device generates.

It should be noted that in some special cases, such as the drone is not in a low-temperature environment, and the first duty cycle is 0, there is no need to control the heating device to heat the battery, and there is no need to add additional heat to the battery. The battery's own temperature It can also be basically constant.

In addition, it should be noted that the above-mentioned battery's own temperature will change during the charging process of the battery by the charging device, so the first duty cycle will also dynamically change, so the intermittent heating process is not necessarily fixed.

In this embodiment, according to the first duty ratio, the battery is intermittently heated during the charging process of the battery by the charging device to compensate for the battery's own heat loss caused by the low-temperature environment of the battery, so as to ensure that the battery's own temperature is maintained during the charging process. Basically constant, will not interrupt the battery charging process due to the battery's own temperature, ensure that the battery is in a continuous charging state, improve the charging efficiency of the battery, and increase the service life of the battery.

In some embodiments, after the above S603 is executed, S604 and/or S605 may also be executed. It should be noted that the execution order of S604 and S605 is not limited.

S604. In the process of charging the battery by the charging device, if the battery's own temperature is greater than the preset temperature, control the charging device to stop charging the battery, and/or output a prompt message, so The prompt information is used to prompt that the battery's own temperature is greater than a preset temperature.

In this embodiment, since the temperature detection device is provided in the battery, the temperature detection device of the battery can detect the battery's own temperature during the process of charging the battery by the charging device.

If the method of this embodiment is applied to a battery, during the process of charging the battery by the charging device, the battery obtains the battery's own temperature detected by the battery's temperature detection device. Then the battery judges whether the battery's own temperature is greater than the preset temperature. If the battery's own temperature is greater than the preset temperature, it means that the battery's own temperature is too high and continuing to charge will be harmful to the battery. The battery control charging device stops charging the battery, such as a battery Sending the charging stop instruction information to the charging device, and accordingly, the charging device stops the charging process of the battery according to the charging stop instruction information obtained from the battery. Or, the battery outputs a prompt message (for example, a flashing indicator light, or a buzzer sound through a buzzer), the prompt message is used to prompt that the battery's own temperature is greater than a preset temperature, and the user is informed of the prompt information After that, the connection between the battery and the charging device can be disconnected, and the charging process between the charging device and the battery can be stopped. Or, the battery control charging device stops charging the battery and outputs prompt information. If the battery's own temperature is less than or equal to the preset temperature, the battery continues to obtain the temperature detected by the temperature detection device, and determines whether the temperature is greater than the preset temperature.

If the method of this embodiment is applied to a charging device, when the charging device charges the battery, the battery's temperature detection device detects the battery's own temperature, and the battery obtains the temperature detected by the temperature detection device and sends it to the charging device. Correspondingly, the charging device obtains the battery's own temperature during the process of charging the battery by the charging device from the battery. If the battery's own temperature is greater than the preset temperature, it means that the battery's own temperature is too high, and continuing to charge will be unfavorable to the battery. The charging device controls the charging device to stop charging the battery, such as disconnecting the charging device and the battery cell group Electric connection. Alternatively, the charging device outputs prompt information (for example, by flashing an indicator light, or buzzing through a buzzer), the prompt information is used to prompt that the battery's own temperature is greater than a preset temperature, and the user is informed of the prompt After the information, the connection between the battery and the charging device can be disconnected, and the charging process between the charging device and the battery can be stopped. Or, the charging device stops charging the battery and outputs prompt information. If the battery's own temperature is less than or equal to the preset temperature, the charging device continues to obtain the battery's own temperature from the battery, and determines whether the temperature is greater than the preset temperature.

S605: If the time period during which the charging device charges the battery is greater than or equal to a preset time period, control the heating device to stop intermittent heating of the battery.

In this embodiment, when the charging device starts to charge the battery, for example, a timer is used to start timing. The time counted is the length of time the charging device charges the battery, and then it is judged whether the charging device is charging the battery for less than the preset duration, if The time that the charging device charges the battery is greater than or equal to the preset time, indicating that the charging device has been charging the battery for too long. Such a long charging process should make the battery full, so there is no need to keep the battery's own temperature basically constant. Then the heating device is controlled to stop intermittent heating of the battery to save energy. If the time period during which the charging device charges the battery is less than the preset time period, then continue to obtain the time period during which the charging device charges the battery, and determine whether the time period is less than the preset time period.

In some embodiments, before performing S601, before the charging device charges the battery, it can also be determined whether the battery's own temperature is less than the preset charging temperature. If the battery's own temperature is less than the preset charging temperature, the heating device is controlled to Battery heating. Until the battery's own temperature is greater than or equal to the preset charging temperature, the charging device is controlled to charge the battery. If the battery's own temperature is greater than the preset charging temperature, the charging device is controlled to charge the battery, and the heating device needs to be controlled to heat the battery before charging.

How the battery or the charging device obtains the battery's own temperature can refer to the relevant description in the foregoing embodiment, which will not be repeated here.

Among them, a possible implementation manner of controlling the heating device to heat the battery before executing S601 may include S600a and S600b.

S600a: Before the charging device charges the battery, if the battery's own temperature is lower than the preset charging temperature, obtain the second duty cycle.

In this embodiment, before the charging device charges the battery and after the connection between the charging device and the battery is established, if the battery's own temperature is lower than the preset charging temperature, the duty cycle for instructing and controlling the heating device to heat the battery is obtained. The duty cycle at is called the second duty cycle.

Optionally, a possible implementation manner for obtaining the second duty cycle in S600a is to determine the second duty cycle according to the battery's own temperature when the charging device is connected to the battery. Among them, the second duty cycle is negatively related to the battery's own temperature.

Optionally, another possible implementation manner for obtaining the second duty cycle in S600a is to determine the second duty cycle according to the battery's own temperature and the preset charging temperature when the charging device is connected to the battery. Among them, the second duty cycle is negatively correlated with the battery's own temperature, and the second duty cycle is positively correlated with the preset charging temperature.

Optionally, the second duty cycle may be a preset duty cycle, and the value of the second duty cycle is a default value and has nothing to do with the battery's own temperature.

Wherein, how the battery or the charging device obtains the battery's own temperature when the charging device is connected to the battery can be referred to the relevant description in the foregoing embodiment, which will not be repeated here.

S600b. Control the heating device to intermittently heat the battery according to the second duty cycle until the battery's own temperature is greater than or equal to a preset charging temperature.

Then control the charging device to charge the battery.

Optionally, the second duty cycle is greater than the first duty cycle, so that the battery can quickly heat up before the charging device charges the battery. The second duty ratio may be 0.5-1, for example. In a special case, the second duty cycle can be 1.

It can be understood that a second control signal may be obtained, and the second control signal includes a second duty cycle. The second control signal may also include other information, such as information for indicating that the battery is in place. Therefore, it can be ensured that the battery is heated when the battery is in place.

In some embodiments, if the method of this embodiment is applied to a charging device, the charging device determines whether the charging device is connected to the battery by detecting the presence of the battery while the charging device is charging the battery. Whether the battery is electrically connected. If it is determined that the charging device is electrically connected to the battery, the charging device continues to charge the battery, and in the process of charging the battery, continues to control the heating device to intermittently heat the battery according to the first duty ratio. If it is determined that the charging device is not connected to the battery, the charging device stops charging the battery and controls the heating device to stop intermittently heating the battery, so as to save energy and avoid power loss.

In some embodiments, if the method of this embodiment is applied to a battery, when the battery supplies power to an external device, the battery also controls the battery pack to output current to the heating device, so that the heating device generates heat . This ensures that when the battery is used in a low-temperature environment, the battery's own temperature will not be too low. For example, after the drone's battery is charged through the above scheme, the drone will work in a low-temperature environment, and the battery will also be handled with the drone. In the same low-temperature environment, through this solution, the battery's own temperature can be maintained at the preset operating temperature basically constant, ensuring the battery's discharge performance. Optionally, an implementation manner for the battery to control the output current of the battery cell group to the heating device may be to control the output current of the battery cell group to the heating device according to the duty ratio, so that the heating device generates heat intermittently.

In some embodiments, the above-mentioned first duty cycle can be replaced with a current, and the implementation principle is similar. For example, the current is determined according to the ambient temperature, and then the heating device is controlled to heat the battery according to the current. Among them, the greater the current, the more the heating device heats the battery. Moreover, the value of the current is negatively related to the ambient temperature, that is, the lower the ambient temperature, the greater the value of the current.
