The embodiment of the invention does not limit the control mode of the forward charging mode and the reverse charging mode.
In the embodiment of the present invention, when the switch circuit 103 is turned on and the voltage regulating circuit 104 stops working, the first device connected to the first charging interface 101 charges the second device connected to the second charging interface 102; when the switch circuit 103 is disconnected and the voltage regulating circuit 104 works, the second device connected to the second charging interface 102 charges the first device connected to the first charging interface 101. In this way, by controlling the switching circuit 103 and the voltage regulator circuit 104, bidirectional charging can be realized, and the adaptability of the charging device can be improved.
Optionally, as shown in fig. 1, the voltage regulating circuit 104 includes a first voltage regulating sub-circuit 1041 and N second voltage regulating sub-circuits 1042, where an input end of the first voltage regulating sub-circuit 1041 is connected to output ends of the N second voltage regulating sub-circuits 1042 respectively;
the output end of the first voltage regulating sub-circuit 1041 is connected with the first charging interface 101, and the input ends of the N second voltage regulating sub-circuits 1042 are correspondingly connected with the N second charging interfaces 102 one by one;
each second voltage regulating sub-circuit 1042 in the N second voltage regulating sub-circuits 1042 is configured to adjust a voltage, which is input to the second voltage regulating sub-circuit 1042 through the corresponding second charging interface 102, to a second target voltage, and output the second target voltage to the first voltage regulating sub-circuit 1041, and the first voltage regulating sub-circuit 1041 is configured to adjust a voltage, which is input to the N second voltage regulating sub-circuits 1042, to the first target voltage.
The specific circuit structure of each second voltage regulating sub-circuit 1042 in the N second voltage regulating sub-circuits 1042 may be the same or different. The specific circuit structures of the first voltage regulating sub-circuit 1041 and the second voltage regulating sub-circuit 1042 may be the same or different. The first voltage regulating sub-circuit 1041 and the second voltage regulating sub-circuit 1042 may both be a voltage boosting circuit; alternatively, both may be voltage-reducing circuits; or one of the first voltage-regulating sub-circuit 1041 and the second voltage-regulating sub-circuit 1042 is a voltage-boosting circuit, and the other is a voltage-reducing circuit; alternatively, the first voltage regulating sub-circuit 1041 and the second voltage regulating sub-circuit 1042 may be both voltage boosting and voltage reducing circuits capable of implementing a voltage boosting function and a voltage reducing function. Taking the value of N as 3 as an example, the input voltages of the three second charging interfaces 102 may be different, in order to unify the input voltages, a Buck/Boost Buck-Boost power conversion circuit may be respectively added in the connection line of each second charging interface 102, and through the conversion of the Buck-Boost power conversion circuit, the input voltage of each second charging interface 102 may be converted into a fixed voltage. For example, 5.2V/2A input by the first second charging interface 102 may be boosted to 6V/1.5A through the corresponding buck-boost power conversion circuit, 9V/2A input by the second charging interface 102 may be reduced to 6V/2.5A through the corresponding buck-boost power conversion circuit, and 4.9V/2A input by the third second charging interface 102 may be boosted to 6V/1.5A through the corresponding buck-boost power conversion circuit, so that the powers input by the three second charging interfaces 102 may be combined to 6V/5.5A. The control circuit 105 may control the first voltage regulating sub-circuit 1041 to meet the charging power requirement of the first charging interface 101 according to the charging power requirement of the device connected to the first charging interface 101, for example, the charging power requirement of the device connected to the first charging interface 101 is 10V/2.25A, and the control circuit 105 may control the first voltage regulating sub-circuit 1041 to convert 6V/5.5A into 10V/2.25A, thereby implementing quick charging.
It should be noted that, if there is no second voltage regulating sub-circuit 1042 to adjust the voltage input by the input end of the second voltage regulating sub-circuit 1042 to the second target voltage, so as to unify the voltages input by the N second charging interfaces 102 to the second target voltage, a situation that the devices connected to the N second charging interfaces 102 are charged with each other may occur. Taking the value of N as 3 for example, the input voltages of the three second charging interfaces 102 may be different, for example, the first second charging interface 102 is connected to a charging head of 5V/2A, and the input voltage may be 5.2V; the second charging interface 102 is connected with a 5V/2A mobile power supply, and the input voltage may be 4.9V; the third second charging interface 102 is connected with a 5V/2A power supply mobile phone, and the input voltage is 5.0V. If the voltage is not regulated by the second voltage regulating sub-circuit 1042, but the three second charging interfaces 102 are forcibly connected to each other, due to the difference in input voltage, there may be a risk of mutual charging, and the device connected to the first second charging interface 102 may charge the device connected to the second charging interface 102 and the device connected to the third second charging interface 102.
In this embodiment, the first voltage regulating sub-circuit 1041 and the N second voltage regulating sub-circuits 1042 are used to adjust the voltage, so as to accurately provide adaptive charging power for the first device connected to the first charging interface 101, thereby enabling the charging apparatus to have better adaptability.
Optionally, the first voltage regulating sub-circuit 1041 and the second voltage regulating sub-circuit 1042 are both voltage boosting circuits or both voltage reducing circuits.
The first voltage regulating sub-circuit 1041 and the second voltage regulating sub-circuit 1042 may be Buck-boost (boost-boost) polarity reversal boost circuits, or may also be other circuits having a boost or Buck function.
In this embodiment, the first voltage regulating sub-circuit 1041 and the second voltage regulating sub-circuit 1042 are both a voltage boosting circuit or a voltage reducing circuit, so as to implement voltage boosting or voltage reducing, and thus, the output voltage of the device connected to the second charging interface 102 is not strictly required, and the adaptability of the charging device can be improved.
Optionally, as shown in fig. 1, the switch circuit 103 includes N electronic switches 1031, first ends of the N electronic switches 1031 are connected to the N second charging interfaces 102 in a one-to-one correspondence, and second ends of the N electronic switches 1031 are connected to the first charging interface 101.
Wherein the electronic switch 1031 may be a MOSFET metal-oxide semiconductor field effect transistor. As shown in fig. 1, the switch circuit 103 includes a first electronic switch K1, a second electronic switch K2, and a third electronic switch K3. The switch circuit may further comprise a fourth electronic switch K4, when the device connected to the first charging interface 101 may communicate directly with the device connected to the second charging interface 102, K4 may be in a closed state; when the device connected to the first charging interface 101 cannot directly communicate with the device connected to the second charging interface 102, the K4 may be in the disconnected state, and the communication module in the control circuit 105 is responsible for the communication between the device connected to the first charging interface 101 and the device connected to the second charging interface 102.
In this embodiment, the N electronic switches 1031 control the on/off of the N second charging interfaces 102 and the first charging interface 101, respectively, so that the connection state between each second charging interface 102 and the first charging interface 101 can be controlled individually.
Optionally, as shown in fig. 1, the charging device further includes a first detection circuit 106 connected to the first charging interface 101 and N second detection circuits 107 connected to the N second charging interfaces 102 in a one-to-one correspondence manner, where the first detection circuit 106 and the second detection circuit 107 are both connected to the control circuit 105;
when the switch circuit 103 is turned on, if the first detection circuit 106 satisfies a first condition or the N second detection circuits 107 satisfies a second condition, the control circuit 105 controls the switch circuit 103 to be turned off;
when the voltage regulating circuit 104 is operating, if the first detection circuit 106 satisfies the first condition or the N second detection circuits 107 satisfies the second condition, the control circuit 105 controls the voltage regulating circuit 104 to stop operating;
the first condition is that the first detection circuit 106 detects that the voltage of the first charging interface 101 is greater than a first preset value or detects that the current of the first charging interface 101 is greater than a second preset value, and the second condition is that the N second detection circuits 107 detect that the voltage of any one of the second charging interfaces 102 is greater than a third preset value or detect that the current of any one of the second charging interfaces 102 is greater than a fourth preset value.
The first preset value can be the same as or different from the third preset value; the second preset value may be the same as or different from the fourth preset value. The first detection circuit 106 and the second detection circuit 107 may have the same or different circuit configurations. A circuit configuration that can be used to detect a voltage or a current may be used as the first detection circuit 106 and the second detection circuit 107. As shown in fig. 1, the control circuit may further include a sampling module, where the sampling module receives the voltages or currents detected by the first detection circuit 106 and the second detection circuit 107, performs analog-to-digital conversion processing, and performs control according to a processing result. When the voltage regulating circuit 104 includes the first voltage regulating sub-circuit 1041 and the N second voltage regulating sub-circuits 1042, the input end of the first voltage regulating sub-circuit 1041 may be connected to a third detection circuit, and if the third detection circuit detects that the input voltage of the first voltage regulating sub-circuit 1041 is greater than a fifth preset value or the input current of the first voltage regulating sub-circuit 1041 is greater than a sixth preset value, the control circuit 105 may control the voltage regulating circuit 104 to stop working, which may protect the voltage regulating circuit 104.
In this embodiment, the first detection circuit 106 and the second detection circuit 107 perform overvoltage detection or overcurrent detection, so that damage to the device connected to the first charging interface 101 and the device connected to the second charging interface 102 due to an excessive voltage or an excessive current is avoided, and the safety of the charging device can be improved.
Referring to fig. 2, fig. 2 is a flowchart of a charging control method according to an embodiment of the present invention, where the method is applied to the charging device according to the embodiment of fig. 1, and the method includes:
And controlling the switching circuit to be disconnected and controlling the voltage regulating circuit to work so as to charge second equipment connected with the second charging interface to first equipment connected with the first charging interface.
After the charging device is powered on, the charging mode can be judged, and a 1-to-1 forward charging mode, a 1-to-multiple forward charging mode or a multiple-to-1 reverse charging mode is judged. Under a 1-to-1 forward charging mode and a 1-to-multiple forward charging mode, controlling first equipment connected with the first charging interface to charge second equipment connected with the second charging interface, if only one second charging interface is connected with a power receiving end, adopting the 1-to-1 forward charging mode, and if at least two second charging interfaces are connected with the power receiving ends, adopting the 1-to-multiple forward charging mode; and in a multi-pair 1 reverse charging mode, controlling second equipment connected with the second charging interface to charge first equipment connected with the first charging interface.
In addition, the Charging types of the device connected with the first Charging interface and the device connected with the second Charging interface can be identified, the input voltage values of the first Charging interface and the second Charging interface are continuously polled and detected, and if the voltage values are detected to exist, a BC1.2(Battery Charging Specification 1.2) protocol can be simulated to detect the Charging types. If a DCP (Dedicated Charging Port) communication mode is detected, the connected Charging terminal can be considered as a Charging terminal determined by a charger and the like; if the communication mode is detected as an SDP (Standard downlink Port) communication mode, it can be considered that a device such as a mobile phone or a tablet that can be used as a charging terminal or a receiving terminal is connected. For example, if it is detected that the device connected to the first charging interface is a charging terminal and one device connected to the second charging interface is a mobile phone, it may be determined that a 1-to-1 forward charging mode needs to be used; if the device connected with the first charging interface is detected to be a charging end and the devices connected with the second charging interfaces are both mobile phones, the fact that a 1-pair multi-forward charging mode needs to be used can be judged; if the device connected with the first charging interface is detected to be a mobile phone, the device connected with the first second charging interface is detected to be a mobile phone, and the device connected with the second charging interface is detected to be a mobile power supply, it can be judged that a plurality of pairs of 1 reverse charging modes need to be used.
