The following describes a dialing method and a terminal provided by the present invention in detail with reference to specific embodiments.
Example 1
Referring to fig. 1, a schematic flow chart of a control method for a protection function according to an embodiment of the present invention includes:
step 101, detecting a connection state between a battery management system and a mobile device.
In an embodiment of the present invention, the battery module includes a battery management system and at least one battery module, and each battery module may include at least one battery cell.
In the embodiment of the present invention, the removable device may include, but is not limited to: unmanned aerial vehicles, airships, and the like.
In the embodiment of the present invention, the connection state between the battery management system and the mobile device may include, but is not limited to: an online state and a disconnected state.
For example, the method of detecting the connection state between the battery management system and the removable device may include, but is not limited to, the following two methods:
the first method is that the battery management system is connected with the mobile equipment through a communication port, and the connection state between the battery management system and the mobile equipment is detected by detecting whether the battery management system and the mobile equipment perform data communication within a preset time duration and according to whether the battery management system and the mobile equipment perform data communication within the preset time duration.
In a specific application scenario, the battery management system may be connected to the mobile device through a communication port of the connector, the battery management system detects a connection state between the battery management system and the mobile device by detecting whether data communication is performed between the battery management system and the mobile device within a preset time duration, when it is detected that the data communication is performed between the battery management system and the mobile device within the preset time duration, the battery management system and the mobile device are in an online state, otherwise, the battery management system and the mobile device are in a disconnected state.
For example, as shown in fig. 2, a connection diagram between a specific battery module and a mobile device provided in an embodiment of the present invention is shown, where the battery module is not shown in the diagram, the mobile device takes an unmanned aerial vehicle as an example, and an unmanned aerial vehicle system is disposed on the unmanned aerial vehicle. As shown in fig. 2, the battery management system may be connected to the unmanned aerial vehicle through a Serial data Bus (SDA) and/or a Serial Clock Bus (SCL) of a communication port of the connector, and if the preset duration is 1 second, the battery management system determines whether the SDA and/or SCL data signal line ports of its connector receive a data signal sent by a flight control system of the unmanned aerial vehicle within 1 second, if so, the battery management system and the unmanned aerial vehicle are in an online state, otherwise, the battery management system and the unmanned aerial vehicle are in a disconnected state.
It should be noted that the unmanned aerial vehicle system and the battery module can be connected through the SDA and/or SCL data signal line ports of their respective connectors, and when the SDA and/or SCL data signal line ports of the unmanned aerial vehicle system receive the data signal sent by the battery management system, the battery management system sends a feedback or response signal to the battery management system, and when the battery management system receives the feedback or response signal through the SDA and/or SCL data signal line ports of its own connectors, the battery management system and the unmanned aerial vehicle system can still be detected to be in an online state; otherwise, the battery management system and the unmanned aerial vehicle system are in a disconnected state.
And secondly, the battery management system is connected with the mobile equipment through a communication port, and the connection state between the battery management system and the mobile equipment is detected by detecting whether the level signal of a specified pin in a connector between the battery management system and the mobile equipment changes or not and according to whether the level signal of the specified pin in the connector between the battery management system and the mobile equipment changes or not.
In a specific application scenario, the battery management system may be connected to the mobile device through a communication port of the connector, and the battery management system detects whether a level signal of a designated pin of the connector between itself and the mobile device changes, and detects a connection state between the battery management system and the mobile device according to a preset initial level signal of the pin when detecting that the level signal of the designated pin of the connector between the battery management system and the mobile device changes.
For example, when the level signal of the designated pin is at a low level when the preset battery management system is disconnected from the mobile device, it is determined that the battery management system and the mobile device are in an online state when it is detected that the level signal of the designated pin of the connector between the battery management system and the mobile device changes to a high level. When the level signal of the designated pin of the connector when the preset battery management system is connected with the mobile equipment is at a low level, when the level signal of the designated pin of the connector between the battery management system and the mobile equipment is detected to change and the level is changed into a high level, the disconnection state between the battery management system and the mobile equipment is judged.
For example, as shown in fig. 3, a connection diagram between a specific battery module and a mobile device provided in an embodiment of the present invention is shown, where the battery module is not shown in the diagram, the mobile device takes an unmanned aerial vehicle system as an example, a level signal of a communication port Enable pin (Enable, EN) of a connector when a preset battery management system is disconnected from the unmanned aerial vehicle system is a low level, the mobile device takes an unmanned aerial vehicle as an example, and the unmanned aerial vehicle is provided with an unmanned aerial vehicle system. As shown in fig. 3, the battery management system may be connected to the unmanned aerial vehicle system through an Enable pin (EN) of the communication port of the battery connector, and when it is detected that the level of the EN pin of the connector of the battery management system changes to a high level, it is determined that the battery management system and the unmanned aerial vehicle system are in an online state; and when the fact that the level of the EN pin of the connector of the battery management system is unchanged is detected, the disconnection state between the battery management system and the unmanned aerial vehicle system is judged.
It should be noted that the unmanned aerial vehicle system and the battery module may be connected through an Enable pin (Enable, EN) of a communication port of each connector, the level signal of the EN pin of the connector when the battery management system is disconnected from the unmanned aerial vehicle system is also set to be a low level in advance by the unmanned aerial vehicle system, and when the battery management system obtains that the level signal of the EN pin of the unmanned aerial vehicle system changes, it can still be determined that the battery management system and the unmanned aerial vehicle system are in an online state; otherwise, the battery management system and the unmanned aerial vehicle system are in a disconnected state.
And 102, starting or closing the protection function of the battery module in which the battery management system is positioned according to the connection state between the battery management system and the movable equipment.
If the connection state between the battery management system and the mobile device detected in step 101 is an online state, the protection function of the battery module in which the battery management system is located is turned off; and if the connection state between the battery management system and the mobile equipment detected in the step 101 is a disconnection state, starting a protection function of a battery module in which the battery management system is located.
Specifically, when the battery management system is detected to be in an online state with the mobile device, the protection function of the battery module in which the battery management system is located is closed. For example, be online state between battery management system and the unmanned aerial vehicle system, unmanned aerial vehicle has been packed into to the battery module in the battery module at battery management system place promptly, in order to guarantee that this unmanned aerial vehicle can not appear situations such as outage in flight, need close battery module's protect function to make battery module constantly be the unmanned aerial vehicle power supply.
And when the battery management system is detected to be in a disconnected state with the mobile equipment, starting the protection function of the battery module in which the battery management system is positioned. For example, be off-state between battery management system and the unmanned aerial vehicle system, when unmanned aerial vehicle was not packed into to the battery module in the battery module at battery management system place promptly, in order to avoid battery module performance degradation and damage scheduling problem to appear, need open battery module's protect function.
In the embodiment of the invention, the battery module is protected according to the connection state of the battery management system and the mobile equipment, the battery module is distinguished and processed in different connection states, and the battery module is protected under the condition that the power supply of the battery module to the mobile equipment is not influenced, so that the problems of performance reduction, damage and the like of the battery module are avoided.
In the embodiment of the present invention, the protection functions of the battery module may include, but are not limited to: at least one of a discharge overcurrent protection function and a discharge overtemperature protection function of the battery module.
For example, the method for starting the protection function of the battery module in which the battery management system is located may include, but is not limited to:
and monitoring at least one parameter of current, temperature, voltage and output power of the battery module according to a corresponding threshold preset for each parameter by the discharge overcurrent protection function and/or the discharge overtemperature protection function of the battery module, so that the monitored parameter does not exceed the corresponding threshold.
The method comprises the steps of presetting corresponding threshold values for all parameters according to the discharge overcurrent protection function and/or the discharge overtemperature protection function of the battery module, and presetting at least one threshold value in current, temperature, voltage and output power of the battery module according to the discharge overcurrent protection function and/or the discharge overtemperature protection function of the battery module.
For example, the threshold corresponding to the current in the preset parameter is 5 amperes, and after the protection function of the battery module is started, if the output current of the battery module exceeds 5 amperes, the power supply circuit of the battery module is disconnected or adjusted, so that the output current of the battery module does not exceed 5 amperes. Or, for example, the threshold corresponding to the output power in the preset parameter is 10W, and after the protection function of the battery module is started, if the output power of the battery module exceeds 10W, the power supply circuit of the battery module is disconnected.
In specific application scene, like mobile device is unmanned aerial vehicle, at unmanned aerial vehicle flight in-process, the condition of outage can not appear in the battery that unmanned aerial vehicle used, consequently, controls the residual power of unmanned aerial vehicle battery through the output in the parameter, can ensure that unmanned aerial vehicle battery power not enough problem can not appear in unmanned aerial vehicle flight in-process.
