Referring to fig. 1, a schematic diagram of a charging circuit is shown, and the charging circuit can be applied to an electronic device. The charging circuit includes:

the detection module 1 is electrically connected with the charging interface A and is used for detecting the charging parameters output by the charging interface A;

the charge pump body module 2 comprises N charge pump bodies 201 which are arranged in parallel and are used for charging the battery component B after processing charging parameters; wherein, under the condition of different charging parameters, the number of the charge pump bodies 201 electrically connected with the detection module 1 is different; the voltage conversion ratio of the charge pump body 201 is M:1, the current conversion ratio is 1:M, N is more than or equal to 2, and M is more than or equal to 3.

The detection module 1 is electrically connected with the charging interface A, and the charging interface A is connected with a charging wire and is connected with a charger through the charging wire. The charging interface a herein may be a type data interface, such as a type-a type data interface, a type-B type data interface, and a type-C type data interface, or a type data interface that appears later. The charging interface a may be a header of a type interface.

The detection module 1 is a module capable of detecting the charging parameters output by the charging interface a, the structure of the detection module 1 is not limited, and the module capable of detecting the charging parameters belongs to the detection module 1. For example, the current detection module, the voltage detection module, and/or the power detection module, etc., and the charging parameters may include a charging voltage, a charging current, and/or a charging power.

The charge pump body module 2 is a module composed of charge pump bodies and comprises N charge pump bodies 201 which are arranged in parallel, the charge pump body module 2 is connected with the charging interface A through the detection module 1, and the detection module 1 is located between the charge pump body module 2 and the charging interface A. The detection module 1 does not affect the transmission of the charging parameters of the charging interface to the charge pump body module 2.

The charge pump body module 2 is used for charging the battery assembly B after processing the charging parameters, and the charge pump body module 2 can adjust the charging parameters, so that the charging parameters required according to actual demands are obtained, and the battery assembly B is convenient to charge. Under the condition that the charging parameters are different, the number of the charge pump bodies 201 electrically connected with the detection module 1 is different, and as each charge pump body 201 in the charge pump body module 2 is in a parallel state, each charge pump body 201 can be electrically connected with the detection module 1 respectively, so that the charge pump body is electrically connected with the charging interface A through the detection module 1. The charge pump bodies 201 do not affect each other, and the charge pump bodies 201 independently adjust the charging parameters in a state that the charge pump bodies 201 are electrically connected with the detection module 1.

In one embodiment, the charge pump body 201 may be electrically connected to the detection module 1 through a switch, and may be electrically connected to the detection module 1 and disconnected from the detection module 1 according to a controller of an electronic device in which the charging circuit is located, for example, the charge pump body 201 may be electrically connected to the detection module 1 through a switch circuit, and the controller is turned on and off by the switch circuit, so that the charge pump body 201 is electrically connected to and disconnected from the detection module 1.

In one embodiment, the charge pump body module 2 includes N charge pump bodies 201 connected in parallel, each charge pump body 201 is electrically connected to the detection module 1, each charge pump body 201 has an on state and an off state, and the charge pump bodies 201 are started and disconnected according to corresponding control signals. The charge pump body 201 that detection module 1 electricity is connected is in the different circumstances of charging parameter, and the quantity of charge pump body 201 that is connected with detection module 1 electricity is different, can include: in the case of different charging parameters, the number of starts of the charge pump bodies 201 electrically connected to the detection module 1 is different. Each charge pump body 201 is electrically connected with the detection module 1 respectively, each charge pump body 201 has a starting state and a disconnection state, the charge pump body 201 is communicated with the detection module 1 in the starting state, the charge pump body 201 is started, current flows through the charge pump body 201, and the charge pump body 201 adjusts current and/or voltage. In the off state of the charge pump body 201, no current flows through the charge pump body 201 to form a loop.

The number of charge pump bodies 201 electrically connected to the detection module 1 here includes: the charge pump body 201 is electrically connected with the detection module 1 and is in an on state.

The voltage conversion ratio of the charge pump body 201 is M:1, and the current conversion ratio is 1:M, wherein M is greater than or equal to 3. The voltage conversion ratio is a ratio of an input voltage to an output voltage of the charge pump body 201, and the current conversion ratio is a ratio of an input current to an output current of the charge pump body 201.

The charge pump body module 2 has a voltage-reducing and current-increasing function, and each charge pump body 201 also has a voltage-reducing and current-increasing function, and the charge pump body 201 is capable of reducing the voltage input to the charge pump body 201 and increasing the current input to the charge pump body 201. That is, the voltage output by the charging interface a is reduced, and the current output by the charging interface a is increased, that is, the current is increased. The method comprises the steps of reducing the voltage which is input to the charge pump body 201 after the voltage output by the charging interface A passes through the detection module 1, and increasing the current which is input to the charge pump body 201 after the current output by the charging interface A passes through the detection module 1.

The number of the charge pump bodies 201 can be more than or equal to 2, for example, 3, 4, 5, 6, 7, etc., and the number of N can be determined according to actual requirements. The greater N, the greater the number of charge pump bodies 201. In the state where the N charge pump bodies 201 are all turned on, the charging speed is faster as the charging power corresponding to the charging parameters adjusted by the N charge pump bodies 201 is greater.

When the plurality of charge pump bodies 201 are electrically connected to the detection module 1, the plurality of charge pump bodies 201 are arranged in parallel, the voltage conversion ratios of the charge pump bodies 201 are the same, and are M:1, and the current conversion ratios of the charge pump bodies 201 are the same, and are the ratio 1:M, so that the outputs of the plurality of charge pump bodies 201 are the same. When the battery pack B is charged, the voltage input to the battery pack B is the output voltage of each charge pump body 201. The current input to the battery assembly B is the sum of the output currents of the respective charge pump bodies 201.

After N is determined, the greater the number of charge pump bodies 201 electrically connected to the detection module 1, the greater the charging power corresponding to the charging parameters adjusted by the N charge pump bodies 201, and the faster the charging speed.

In one embodiment, the battery assembly may include a single cell battery or may include a battery with multiple cells connected in series.

In one embodiment, referring to fig. 2, a second schematic diagram of a charging circuit is shown.

In this embodiment, M is equal to 3, n is equal to 5, and the charge pump body module 2 includes 5 charge pump bodies 201, and the voltage conversion ratio of each charge pump body 201 is 3:1, and the current conversion ratio is 1:3.

When the 5 charge pump bodies 201 are all electrically connected with the detection module 1, the 5 charge pump bodies 201 adjust charging parameters at the same time, for example, charging voltage is 30V, charging current is 2A, then output voltage of each charge pump body 201 is 10V, output current is 6A, then voltage output from the 5 charge pump bodies 201 to the battery component B is 10V, current is 30A, charging power is 300W, and thus charging power is improved.

Under normal conditions, as the rated voltage of the single battery core is 5V, the rated voltage of the battery component B with the serial double battery core is 10V, when the battery component comprises the serial double battery core, the charging voltage which the charging interface a is allowed to access can be raised to 30V by using the charge pump body 201 with the parallel 5 voltage conversion ratios of 3:1, so that the charging power of the charging circuit can reach 300W, the charging efficiency of the charging circuit is effectively improved, and the use experience of a user is improved.

In one embodiment, all of the 5 charge pump bodies 201 electrically connected to the detection module 1 may be determined according to the charging parameters, and the number of charge pump bodies 201 electrically connected to the detection module 1 corresponding to different charging parameters may be different. For example, the larger the charging power, the larger the number of charge pump bodies 201 electrically connected to the detection module 1. When the charging power reaches the corresponding power, one charge pump body 201 is controlled to be electrically connected with the detection module 1, and when the charging power reaches the other higher corresponding power, the other charge pump body 201 is controlled to be electrically connected with the detection module 1 again. When the charging power is reduced to the corresponding power, one charge pump body 201 is disconnected from the detection module 1, and when the charging power is reduced to the other smaller corresponding power, the other charge pump body 201 is disconnected from the detection module 1 again.

In one embodiment, referring to fig. 3, a third schematic diagram of a charging circuit is shown.

In this embodiment, M is equal to 3, n is equal to 4, and the charge pump body module 2 includes 4 charge pump bodies 201, and the voltage conversion ratio of each charge pump body 201 is 3:1, and the current conversion ratio is 1:3. The electric connection between the charge pump body 201 and the detection module may include that 1 charge pump body 201 is electrically connected with the detection module 1, 2 charge pump bodies 201 are electrically connected with the detection module 1, 3 charge pump bodies 201 are electrically connected with the detection module 1, or 4 charge pump bodies 201 are electrically connected with the detection module 1.

In one embodiment, referring to fig. 4, a schematic diagram of a charging circuit is shown.

In this embodiment, M is equal to 3, n is equal to 3, and the charge pump body module 2 includes 3 charge pump bodies 201, and the voltage conversion ratio of each charge pump body 201 is 3:1, and the current conversion ratio is 1:3.

In one embodiment, referring to fig. 5, a schematic diagram of a charging circuit is shown.

In this embodiment, M is equal to 3, n is equal to 2, and the charge pump body module 2 includes 2 charge pump bodies 201, and the voltage conversion ratio of each charge pump body 201 is 3:1, and the current conversion ratio is 1:3.

In another embodiment, the charging parameters include: charging current and/or charging voltage;

the number of charge pump bodies electrically connected with the detection module 1 is positively correlated with the product of the charging current and the charging voltage, the charging current and/or the charging voltage.

The larger the charging voltage is, the more the charge pump bodies 201 are electrically connected with the detection module 1; the greater the charging current, the greater the number of charge pump bodies 201 electrically connected to the detection module 1; the product of the charging current and the charging voltage is charging power, and the larger the charging power is, the larger the number of the charge pump bodies 201 electrically connected with the detection module 1 is. Therefore, when the charging parameter is larger, higher power can be obtained through the charge pump body module 2, and the power output by the charge pump body module is applied to the battery component B, so that the charging efficiency and the charging speed of the battery component B are improved conveniently.

In one embodiment, referring to fig. 6, which is a schematic diagram of a detection module, the detection module 1 includes:

the sampling component 101 is electrically connected with the charging interface A and the charge pump body module 2 respectively;

and the processor 102 is electrically connected with the sampling component 101, and is used for acquiring voltage signals at two ends of the sampling component 101 and/or current signals flowing through the sampling component 101, and generating detection signals of the charging parameters according to the voltage signals and/or the current signals.

The detection signal indicates whether the charging parameters meet the adjustment conditions of the electric connection between each charge pump body and the detection module 1; the number of charge pump bodies electrically connected with the detection module 1 corresponding to different adjustment conditions is different.

Sampling component 101 may be any device capable of sampling either a current or a voltage, such as a sampling resistor. One end of the sampling part 101 is electrically connected with the charging interface a, and the other end is electrically connected with the charge pump body module 2. In this way, the charging current and/or the charging voltage transmitted from the charging interface a to the charge pump body module 2 can be collected. The sampling unit 101 may be a voltage sampling unit or a current sampling unit.

The sampling part 101 is connected with the charging interface A and the charge pump body module 2 in series, one end of the sampling part 101 is connected with the charging interface A, the other end is connected with the charge pump body module 2, and the charging interface A, the sampling part 101 and the charge pump body module 2 are connected in series.

The processor 102 may be any processor capable of acquiring a voltage signal across the sampling part 101 and/or a current signal flowing through the sampling part 101, and generating a detection signal of a charging parameter according to the voltage signal and/or the current signal. The processor 102 is matched with the sampling unit 101, and the processor 102 can collect voltage signals at two ends of the sampling unit 101 so as to determine the current flowing through the sampling unit 101 according to the voltage signals and the resistance value of the sampling unit 101. Since the sampling part 101 is connected in series with the charging interface a and the charge pump body module 2, the current flowing through the three is the same, and the charging current outputted from the charging interface a, the current flowing through the sampling part 101 and the current outputted to the charge pump body module 2 are the same. Thus, the charging current output by the charging interface A can be obtained.

For example, the processor 102 is an analog-to-digital converter (ADC), the sampling component 101 is a sampling resistor, and can collect voltages across the sampling resistor, so as to determine a voltage difference between the voltages across the sampling resistor, and determine a current flowing through the sampling resistor according to a resistance value of the sampling resistor.

In addition, the processor 102 can also collect the current signal flowing through the sampling component 101, then determine the voltage signals at two ends of the sampling component 101 according to the resistance value of the sampling component 101, and further determine the charging voltage output by the charging interface a according to the voltage signals at two ends of the sampling component 101.

Processor 102 may generate a detection signal of the charging parameter based on the detected voltage signal and/or current signal. The detection signal indicates whether the charging parameter meets the adjustment condition of the number of the charge pump bodies electrically connected with the detection module 1; the number of charge pump bodies electrically connected with the detection module 1 corresponding to different adjustment conditions is different.

For example, the charging parameters may include a plurality of ranges, and the number of turned-on charge pump bodies 201 is different for different ranges of the detection signals corresponding to the charging parameters. The number of charge pump bodies electrically connected with the detection module 1 corresponding to different adjustment conditions is different.

The charging power comprises 5 power ranges from the power range 1 to the power range 5, and the power corresponding to the power ranges from the power range 1 to the power range 5 is sequentially increased. Each power range corresponds to one range of detection signals, and the power ranges corresponding to the detection signals in different ranges are different. The detection signal 1 corresponds to the power range 1, which means that one charge pump body 201 is electrically connected to the detection module 1, i.e. one charge pump body 201 is electrically connected to the detection module 1. The detection signal 2 corresponds to the power range 2, which indicates that the 2 charge pump bodies 201 are electrically connected to the detection module 1, i.e. the 2 charge pump bodies 201 are electrically connected to the detection module 1. On the basis of the electric connection of one charge pump body 201 and the detection module 1, one charge pump body 201 and the detection module 1 are electrically connected again.

In the power range 3 corresponding to the detection signal 3, it means that 3 charge pump bodies 201 are electrically connected with the detection module 1, i.e. 3 charge pump bodies 201 are in an electrically connected state with the detection module. On the basis that 2 charge pump bodies 201 are electrically connected with the detection module 1, one charge pump body 201 is turned on again.

In the power range 4 corresponding to the detection signal 4, it means that the 4 charge pump bodies 201 are electrically connected with the detection module 1, i.e. the 4 charge pump bodies 201 are in an electrically connected state with the detection module. On the basis that the 3 charge pump bodies 201 are electrically connected with the detection module 1, one charge pump body 201 is electrically connected with the detection module 1 again.

In the power range 5 corresponding to the detection signal 5, it means that the 5 charge pump bodies 201 are electrically connected with the detection module 1, i.e. the 5 charge pump bodies 201 are in an electrically connected state with the detection module 1. On the basis that the 4 charge pump bodies 201 are electrically connected with the detection module 1, one charge pump body 201 is electrically connected with the detection module 1 again.

In another embodiment, the processor 102 is further configured to generate an early warning signal according to the voltage signal and/or the current signal collected by the processor 102, where the early warning signal is used to indicate that the charging parameter exceeds the preset parameter. In this way, when the charging parameter exceeds the preset parameter, a prompt can be sent to prompt overvoltage, overcurrent or overlarge power and the like, so that the damage to the charging current and the battery assembly B is reduced.

In another embodiment, referring to fig. 7, which is a partial schematic diagram of a charging circuit, the charging circuit further includes:

the switch 3 is electrically connected with the charging interface a and the detection module 1 respectively, and is used for controlling whether the detection module 1 detects the charging parameter and whether the charge pump body module 2 charges the battery component B.

The switch 3 is located between the charging interface a and the detection module 1, and is used for controlling whether the current and the voltage of the charging interface a flow to the detection module 1 and the charge pump body module 2.

The switch 3 may include:

the first transistor Q1, the first non-control end of the first transistor is connected with the charging interface A electrically, the second non-control end of the first transistor is connected with the detection module 2 electrically;

the second resistor R2, one end of the second resistor R2 is connected with the first control end;

and a second control end of the second transistor Q2 is connected with a controller of the electronic equipment where the charging circuit is positioned, a third non-control end of the second transistor Q2 is connected with the other end of the second resistor R2, and a fourth non-control end of the second transistor Q2 is grounded.

The first transistor Q1 may be a P-type MOS transistor, the second transistor Q2 is an N-type MOS transistor, the first non-control end is a source, the second non-control end is a drain, the source of the first transistor Q1 is connected to the charging interface a, the drain of the first transistor Q1 is connected to the detection module 1, and the first resistor R1 is connected to the source and the gate of the first transistor Q1, respectively.

The source electrode of the second transistor Q2 is grounded, the drain electrode of the second transistor Q2 is connected with the second resistor R2, and the grid electrode of the second transistor Q2 is connected with the controller.

It can be understood that when the gate of the second transistor Q2 receives the first control signal (i.e., the high level signal) output by the controller, the second transistor Q2 is turned on, the gate voltage of the first transistor Q1 is smaller than the source voltage of the first transistor Q1 (i.e., the gate of the first transistor Q1 receives the low level signal), and the first transistor Q1 is turned on, so as to implement the connection between the charging interface a and the detection module 1.

When the gate of the second transistor Q2 receives the second control signal (i.e., the low level signal) output by the controller, the second transistor Q2 is turned off, the gate voltage of the first transistor Q1 is equal to the source voltage of the first transistor Q1 (i.e., the gate of the first transistor Q1 receives the high level signal), and the first transistor Q1 is turned off, so as to disconnect the charging interface a from the detection module 1.

and a controller (not shown in fig. 1) electrically connected with the detection module and the charge pump body module, for adjusting whether each charge pump body in the charge pump body module is electrically connected with the detection module according to the charging parameters of the charging interface detected by the detection module.

The controller can control whether each charge pump body is electrically connected with the detection module 1 through the connection and the closing of the control switch. And a switch is connected between each charge pump body and the detection module, and in order to distinguish the switch from the switch in the embodiment, the switch connected with each charge pump body is marked as an access switch, and each charge pump body is connected with the detection module through the access switch.

For example, 5 individual charge pump bodies, have an access switch respectively between every individual charge pump body and the detection module, charge pump body and detection module communicate when access switch switches on, and charge pump body and detection module disconnection when access switch disconnection.

In one embodiment, the controller controls different numbers of the charge pump bodies to be switched and electrically connected with the detection module under the condition that the charging parameters are different.

In one embodiment, the controller is electrically connected with a switch in the charging circuit for controlling the on and off of the switch; the switch is used for controlling whether the detection module detects the charging parameter and whether the charge pump body module charges the battery assembly.
