In this embodiment, the power level of the battery adapter 2 corresponds to the power value of the battery to be charged that can be accommodated by the battery adapter 2; the purpose of identifying the power class of the battery adapter 2 is to identify the power value of a battery to be charged that is preset and accommodated by the battery adapter 2. The specific correspondence and the preset method are not limited in this embodiment.
In this embodiment, the battery to be charged is a battery of a video camera, a monitor, a camera, or a fill light, and the battery can be detached from the device. It should be noted that the capacity of the battery to be charged refers to the amount of electric energy stored in the battery, that is, the amount of electric energy of the battery in a fully charged state, and different capacities can achieve better charging effect and safety performance with different charging powers. For batteries of products such as video cameras, monitors, cameras, fill lights, etc., the batteries with different powers have different shapes and structures, for example, different specific structures and/or sizes. Therefore, by setting the second region 21 of the battery adapter to a shape structure matching the shape structure of the batteries with different capacities, the purpose of identifying the capacity of the battery to be charged by identifying the power level of the battery adapter can be achieved. That is, the difference of the shape and structure of the second region 21 on the battery adapter 2 can reflect the difference of the battery capacity; the battery adapter 2 is provided with an identification circuit, and the power grade difference of the battery adapter 2 is identified through the difference of identification signals output by the identification circuit, namely, the capacity difference of the batteries to be charged which can be accommodated by the battery adapter 2 is identified.
In addition, in the embodiment, the first identification circuit and the second identification circuit are matched with each other for identification, so that the method is more convenient for design of triggering different identification signals by utilizing the difference of the entity structure, the entity structure does not need to be differentially designed, and various dies are not needed for producing related products.
In some embodiments, the charging module sets a charging power according to the identification result; the charging power is provided with a plurality of gears, the power values of different gears are different in size, and each gear corresponds to one power level.
In this embodiment, compared to the conventional charging module, a function of setting the charging power according to the recognition result is added, and the adjusting means of the charging power is a technical means known in the art and is not limited in this embodiment.
In some embodiments, the first identification port group includes a voltage value input port, the second identification port group includes a voltage value output port, the voltage value input port is used for receiving the voltage value output by the voltage value output port, and the identification result is the voltage value.
In the present embodiment, different power levels of different battery adapters 2 are identified by using different voltage values output by the second identification port group. The purpose of identifying the power of the battery adapter sockets with different power levels can be achieved by setting the output voltage values of the voltage division circuits of the battery adapter sockets with different power levels to different values.
In some implementations, the first identification port group includes a voltage value input port, the second identification port group includes a voltage value output port, the voltage value input port is configured to receive a voltage value output by the voltage value output port, and the identification result is the voltage value.
Referring to FIG. 7, the first identified port group includes port 3VDD-OUT, which outputs power to supply power to port 3VDD-IN of the second identified port group. The first identified port group also includes a port 4V-IN that receives voltage values output from a port 4V-OUT of the second identified port group. The second identification circuit comprises a voltage division circuit consisting of a power supply VDD, a resistor R1, a resistor R2 and a port GND, and a connecting point between the resistor R1 and the resistor R2 is connected with an output port 4V-OUT of the voltage value. The port 4V-IN of the first identification port group is sequentially connected with an analog-digital conversion circuit and a charging circuit IN the charging module, and the voltage value is converted into a digital signal which is identified by a control part IN the charging circuit and controls the charging power. The ground terminal in this embodiment is the aforementioned negative terminal, and since the negative terminal is electrically connected to the charging module, the negative terminal is connected to the ground terminal of the charging module, and the levels of the two terminals are the same. In fig. 7, the power supply VDD is obtained from the power supply VCC through a voltage stabilizing circuit, which is only an example, and the obtaining manner of the power supply VDD is not limited in this embodiment.
In some embodiments, the first identification port group includes at least one status input port, the second identification port group includes at least one status output port, the at least one status input port is configured to receive a status value output by the at least one status output port, and the identification result is the status value.
In this embodiment, the power class of the battery adaptor 2 is identified by detecting the state value of the identification port group. It will be appreciated that if a port has 2 status values, then a port may identify 2 power levels and two ports may identify 4 power levels.
Thus, in some embodiments, it is further defined that the first identification port group includes at least two status input ports, the second identification port group includes at least two status output ports, the at least two status input ports are configured to receive a combined status value output by the at least two status output ports, and the identification result is the combined status value. As long as the total number of permutation and combination of the combination state values is greater than or equal to the number of gears of the charging power, the identification of the target number of power levels can be realized.
In some embodiments, at least one status output port of the second set of identification ports is electrically connected to a ground terminal of the second set of charging ports through a ground resistor;
all state input ports in the first identification port group are electrically connected with a pull-up power supply through pull-up resistors respectively.
Referring to fig. 8, the second identification circuit IN the battery adaptor 2 of a certain power level includes a resistor R3 and a resistor R4, and the ports IO1-IN are connected to the ground GND through the resistor R3; the port IO2-IN is connected to the ground GND via a resistor R4. The first identification circuit comprises a pull-up resistor R5 and a pull-up resistor R6, the port IO1 is connected to a power supply VDD through the resistor R5, and the port IO2 is connected to the power supply VDD through the resistor R6. When the battery adapter 2 is disposed IN the first region 11, the first charging port group 12 is electrically connected to the second charging port group 22, and the first identification port groups IO1 and IO2 are electrically connected to the second identification port groups IO1-IN and IO2-IN, respectively. At this time, the state value state1 output by the ports IO1-IN and IO1-OUT is at ground level, and the state value state2 output by the ports IO2-IN and IO2-OUT is at ground level. The state logic circuit receives the state combination value (state 1, state 2) transmitted by the ports IO1-IN and IO2-IN as (ground level ).
If the resistor R3 IN the second identification circuit of the battery adapter 2 of the other power class does not exist, the connection between the port IO1-OUT and the port GND is disconnected, the state value state1 output by the port IO1-OUT and the port IO1-IN is suspended, and at this time, the state logic circuit receives the state combination value (state 1, state 2) transmitted by the port IO1-IN and the port IO2-IN as (suspended, ground level).
Therefore, the battery adapter 2 with different power levels can be judged according to the difference of the state combination values. It will be appreciated that two ports, each having two states, may provide 4 permutations for identifying 4 different power levels of the battery adapter 2. The number of the specific identification ports and the number of the state values of each port can be flexibly set, and the requirement that the number of all permutation and combination of all the ports is more than or equal to the number of the power levels to be identified is met.
In this embodiment, the power supply VDD may also be obtained from the power supply VCC through a voltage stabilizing module, and the specific obtaining manner is not limited in this embodiment.
In some embodiments, the ground resistance is a zero ohm resistance.
In some embodiments, the first region is a plurality of first regions, each of the first regions being adapted to receive one of the battery adapters. The number of the first regions may be flexibly set according to an actual application scenario, and is not limited in this embodiment.
