Please refer to FIG. 6, which is a schematic flowchart of steps of another battery control method provided by an embodiment of the present application.

Specifically, as shown in FIG. 6, the battery control method includes steps S201 to S204.

S201. Obtain the current temperature of the battery of the movable platform.

S202: Determine whether the current temperature is greater than or equal to a preset charging limit temperature.

S203. If the current temperature is greater than or equal to the preset charging limit temperature, lower the current temperature of the battery so that the current temperature of the battery is less than the preset charging limit temperature, so that the battery meets the preset charging limit temperature. When the condition is to be charged, the battery can be charged immediately.

S204: When the battery satisfies the preset to-be-charged condition, and the current temperature of the battery is less than the preset charging limit temperature, output a charging reminder message.

Wherein, the charging reminder information is used to remind the user that the current temperature of the battery is less than the preset charging limit temperature, so as to remind the user that the battery can be charged immediately when the movable platform stops running. It can be voiced or displayed. The charging reminder information is output in at least one of a screen, a vibration, and a light.

In one embodiment, when the battery meets the preset to-be-charged condition and the current temperature of the battery is less than the preset charging limit temperature, the charging reminder information is sent to the control terminal for the control terminal to output the charging reminder information. Wherein, the control terminal may output the charging reminder information through at least one of voice, display screen, vibration, and light. By sending the charging reminder information to the control terminal, the control terminal outputs the charging reminder information, so that the user can quickly know the battery needs of the mobile platform, so that when the user gets the mobile platform, the battery of the mobile platform can be connected immediately Charging equipment so that the battery can be charged immediately.

In one embodiment, when the battery meets the preset to-be-charged conditions and the current temperature of the battery is less than the preset charging limit temperature, the movable platform is controlled to move to the charging device for charging, so that the charging device can immediately charge the battery of the movable platform Charge it. Among them, the charging device can charge the battery in the mobile device by wireless charging, which greatly improves the convenience of charging. Of course, the charging device can also charge the battery in the mobile device by wired charging. . By moving the movable platform to the charging device for charging, the battery does not need to be removed, which can prevent damage to the movable platform or the battery during the process of removing the battery.

In one embodiment, when the battery satisfies the preset to-be-charged condition and the current temperature of the battery is less than the preset charging limit temperature, the movable platform is controlled to move to the charging device, so that the power interface of the charging device is connected to the battery of the movable platform. The charging interface is connected so that the charging device can immediately charge the battery of the mobile platform. By moving the movable platform to the charging device for charging, there is no need to remove the battery, which can prevent damage to the movable platform or the battery during the process of removing the battery.

In one embodiment, after the mobile platform is moved to the charging device, the charging device charges the battery based on the fast charging mode. The constant voltage charging stage of the fast charging mode uses a preset charging strategy to charge the battery. The charging strategy includes the following one: stop charging, stop charging after a preset period of time, and stop charging when the charging current drops to a preset cut-off current. By moving the mobile platform to the charging device, the battery can be prevented from being removed, which can prevent damage to the mobile platform or the battery during the process of removing the battery. At the same time, charging the battery based on the fast charging mode can realize the fast charging of the battery. When there is only one movable platform and one battery, the waiting time of the movable platform can be reduced, and the work efficiency and user experience are greatly improved.

Among them, battery charging generally includes a pre-charging phase, a constant current charging phase, a constant voltage charging phase, and a recharging phase. The specific method of charging the battery based on the fast charging mode by the charging device is: constant current charging of the battery, that is, the battery is currently charged In the constant current charging stage; obtain the charging parameters and/or battery parameters when charging the battery with constant current, and determine whether the battery enters the constant voltage charging stage according to the charging parameters and/or battery parameters; if the battery enters the constant voltage charging stage, use The preset charging strategy corresponding to the constant voltage charging stage charges the battery. In the fast charging mode, the battery is charged through the constant current charging phase and the constant voltage charging phase, so that fast charging can be realized, which is convenient for cycle operation.

The preset charging strategy includes one of the following: stopping charging, stopping charging after a preset period of time, and stopping charging when the charging current drops to a preset cut-off current. Stop charging, that is, no longer charge the battery. For example, the charging device automatically disconnects the charging circuit; for example, sending a stop command to the battery's micro-control unit to make the battery disconnect the charging switch to stop charging; for another example, the charging device automatically disconnects the charging circuit and outputs a prompt message to remind The user battery level has been completed.

After charging for a preset time, stop charging. The preset time is set according to actual needs, for example, the preset time is 1 minute, 2 minutes, or 3 minutes. Stop charging after charging the preset time period; or stop charging after charging the preset time period, and output a prompt message to remind the user that the battery power is complete. The preset duration of the charging is the constant voltage charging stage.

Stop charging when the charging current drops to the preset cut-off current. For example, the constant current charging current is 5.0A. The preset cut-off current can be set to 4.9A, 4.8A or 4.7A. The specific value is not limited here. When the charging current of the battery drops to the preset cut-off current, for example, when it drops to 4.9A, stop charging; or, when the charging current of the battery drops to the preset cut-off current, stop charging, and output a prompt message to remind the user of the battery level completed.

In some embodiments, the size of the preset duration has a negative correlation with the size of the charging rate of the charging device. For example, when the charging rate of the charging device is 1C, the preset duration is set to 3 minutes; when the charging rate of the charging device is 3C, the preset duration is set to 2 minutes; when the charging rate of the charging device is 5C, the preset duration is set to 1 minute. Since the charging rate is 1C, 3C, and 5C, the corresponding constant current charging durations are different, so setting the preset duration with a negative correlation relationship can control the constant voltage charging duration accordingly. It satisfies the user's demand for fast charging of the battery, while taking into account the battery power, thereby improving the user experience.

In some embodiments, the preset cut-off current has a positive correlation with the charging rate of the charging device. For example, when the charging rate of the charging device is 1C, the preset cut-off current is set to 4.7A; when the charging rate of the charging device is 3C, the preset cut-off current is set to 4.8A; when the charging rate of the charging device is 5C, the preset time The preset cut-off current is set to 4.9A. Since the charging rate is 1C, 3C, and 5C, the corresponding constant current charging durations are different, so setting the preset cut-off current with a positive correlation can control the constant voltage charging duration accordingly. It satisfies the user's demand for fast charging of the battery, while taking into account the battery power, thereby improving the user experience.

Specifically, the charging parameters used to characterize the end of constant current charging or the entering of the constant voltage charging phase are obtained, or the battery parameters used to characterize the end of constant current charging or the entering of the constant voltage charging phase are obtained. Determine whether the battery enters the constant voltage charging stage according to the charging parameters and/or the battery parameters.

Exemplarily, the current battery voltage of the battery is acquired, and it is determined whether the battery enters the constant voltage charging stage according to the current battery voltage. Wherein, determining whether the battery enters the constant voltage charging stage according to the current battery voltage is specifically: obtaining a preset charging cut-off voltage, which is used to indicate that the battery enters the constant voltage charging stage from the constant current charging stage; The battery voltage and the preset charging cut-off voltage determine whether the battery enters the constant voltage charging stage.

For example, it is determined whether the difference between the current battery voltage and the preset charging cut-off voltage is less than the preset voltage threshold, and if the difference between the current battery voltage and the preset charging cut-off voltage is less than the preset voltage threshold, it is determined that the battery enters the constant voltage charging stage.

For example, if the current battery voltage is 4.25V, the preset charging cut-off voltage is 4.20V, and the preset voltage threshold is set to 0.1V, it can be determined that the battery enters the constant voltage charging stage. The preset voltage threshold can quickly determine whether the battery enters the constant voltage charging stage.

For example, it is determined whether the current battery voltage is greater than or equal to the preset charging cut-off voltage; if the current battery voltage is greater than or equal to the preset charging cut-off voltage, it is determined that the battery enters the constant voltage charging stage.

For example, the current battery voltage is 4.21V, and the preset charging cut-off voltage is 4.20V, so it can be determined that the battery enters the constant voltage charging stage. By determining whether the current battery voltage is greater than or equal to the preset charging cut-off voltage, it can be accurately determined whether the battery enters the constant voltage charging stage.

It should be noted that the specific values of the preset charging cut-off voltage and the preset voltage threshold are not limited here, and are set according to the battery type and parameters.

Exemplarily, for another example, the current charging current of the battery is obtained; according to the current charging current and voltage, it is determined whether the battery enters the constant voltage charging stage. Among them, determine whether the battery enters the constant voltage charging stage according to the current charging current and voltage, specifically: obtaining the preset charging cut-off current, the preset charging cut-off current is used to characterize the battery from the constant current charging stage to the constant voltage charging stage; according to the current charging current And the preset charging cut-off current to determine whether the battery enters the constant voltage charging stage.

For example, it is determined whether the difference between the preset charging cut-off current and the current charging current is less than the preset current threshold; if the difference between the preset charging cut-off current and the current charging current is less than the preset current threshold, it is determined that the battery enters the constant voltage charging stage.

For example, the preset charging cut-off current is 5.0A, the current charging current is 4.95A, and the preset current threshold is 0.1A. The difference between the preset charging cut-off current and the current charging current is 0.05A, which is less than the preset current threshold 0.1A. This confirms that the battery enters the constant voltage charging phase. The preset current threshold can quickly determine that the battery enters the constant voltage charging phase.

For example, it is determined that the current charging current is less than the preset charging cut-off current; if the current charging current is less than the preset charging cut-off current, it is determined that the battery enters the constant voltage charging stage.

For example, the preset charging cut-off current is 5.0A, and the current charging current is 4.99A, which determines that the battery enters the constant voltage charging stage. By determining that the current charging current is less than the preset charging cut-off current, it can be accurately determined that the battery enters the constant voltage charging stage.

For another example, monitor the charging current of the battery; determine the change trend of the charging current of the battery; if the change trend changes from a steady trend to a downward trend, it is determined that the battery enters the constant voltage charging stage.

In an embodiment, a charging device is used to determine whether the battery includes a reserved capacity, and if the battery includes a reserved capacity, the charging device is used to charge the battery based on a fast charging mode.

Specifically, the battery capacity of the battery is obtained, and whether the battery includes the reserved capacity is determined according to the battery capacity. For example, if the obtained battery capacity is 18.9 Ah, it can be determined that the battery capacity of the battery includes the reserved capacity. It is understandable that the battery capacity of the battery is generally an integer, and if the value corresponding to the reserved capacity is included, it can be determined that the battery includes the reserved capacity. In order to determine whether the battery includes reserved capacity more conveniently and preparedly, the reserved capacity can be set to an uncommon capacity value, such as 0.93Ah. If the battery capacity of the battery is detected as 18.93Ah, it can be determined that the battery includes the reserved capacity. Reserve capacity.

In an embodiment, the battery includes a working capacity and a reserved capacity, and the working capacity and the reserved capacity are determined according to the ratio of the charging power of the constant current charging and the constant voltage charging. For example, if the charging power corresponding to constant current charging is 90%, the charging power corresponding to constant voltage charging is 5%, and the working capacity required for operation is 18Ah, the reserved capacity can be set to 0.9Ah.

In one embodiment, during the process of charging the battery, the charging device stops charging the battery if it detects that the current capacity of the battery is greater than or equal to the charge cut-off capacity, wherein the charge cut-off capacity Less than the rated power of the battery.

If the target charging rate is the same as the current charging rate of the charging device, the current charging rate of the charging device is not adjusted. Among them, the preset time can be set based on actual conditions, which is not specifically limited in this application. The charging temperature of the battery is adapted to the charging rate, which can improve the charging speed while ensuring the safety of the battery.

Specifically, the pre-stored mapping relationship table between the charging temperature and the charging rate is obtained, and the mapping relationship table is queried to obtain the charging rate corresponding to the charging temperature. Among them, it is possible to conduct experiments by adjusting the charging rate of the battery under different charging temperatures to obtain the best charging rate at each charging temperature, thereby establishing a mapping relationship table between the charging temperature and the charging rate. Through the mapping table between the charging temperature and the charging rate, the charging rate can be quickly determined.

In one embodiment, the charging device obtains the current temperature of the battery of the movable platform, and when the current temperature of the battery is less than a preset temperature threshold, raises the current temperature of the battery, and is increasing When the subsequent current temperature of the battery reaches the preset temperature threshold, the battery is charged.
