In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is configured to communicate with the internet wirelessly.
Optionally, as an optional implementation manner, as shown in fig. 2, the method for determining the charging policy includes:
step S202, obtaining battery information of a battery to be charged and output voltage of charging equipment;
as an alternative example, the battery is a battery that can communicate with the processor, and the battery can tell the processor itself the voltage, current, and battery type data at the time of charging. I.e., the processor may communicate with the battery to obtain battery information for the battery.
As an alternative example, battery information includes, but is not limited to: battery signal, maximum charge current of battery, residual capacity, resistance, etc.
As an alternative example, the above-described acquisition of the output voltage of the charging device may be achieved by: sending detection information to a lifting and pressing module through a processor, wherein the detection information is used for indicating the lifting and pressing module to detect the output voltage of the charging equipment; and acquiring the output voltage sent by the voltage boosting and reducing module through the processor.
It should be noted that the step-up and step-down module may perform step-up processing or step-down processing on the output voltage of the charging device, that is, the processor may obtain the output voltage of the charging device through the step-up and step-down module.
Step S204, determining the charging voltage of the battery according to the battery information, and determining the difference value between the output voltage and the charging voltage, wherein the charging state of the battery under the charging voltage is the best;
in an exemplary embodiment, the above determination of the charging voltage of the battery according to the battery information may be achieved by: the battery information is sent to a protocol chip through a processor, wherein different charging voltages corresponding to different battery information are recorded in the protocol chip; and acquiring the charging voltage sent by the protocol chip through the processor.
In this embodiment, the processor may accurately determine the charging voltage of the battery according to the battery information of the battery in the above manner.
It should be noted that, the state of charge of the battery can be understood as follows: in the case where the heat generation of the battery is in a reasonable range, the charge speed of the battery is the fastest.
Step S206, determining a target charging strategy adopted for the battery from at least two charging strategies according to a determination result of whether the difference is within a preset range, where the at least two charging strategies include: and charging the battery by using the output voltage of the charging equipment, and charging the battery by using the voltage obtained by carrying out step-up and step-down processing on the output voltage.
In an exemplary embodiment, the above step S206 is implemented by: determining the target charging strategy to charge the battery by using the output voltage of the charging device under the condition that the judging result indicates that the difference value is within the preset range; and under the condition that the judging result indicates that the difference value is not in the preset range, determining the target charging strategy to charge the battery by using the voltage obtained by carrying out step-up and step-down processing on the output voltage.
It should be noted that if the difference is within the preset range, the charging device is a customized charger matched with the battery (the customized charger in the embodiment of the application refers to a charger with voltage and current set according to a specific battery), and then the output voltage of the charging device can be directly used to charge the battery. If the difference value is not in the preset range, the charging equipment is a universal charger, the processor instructs the step-up and step-down module to adjust the output voltage of the charging equipment according to the type of the battery, and then the adjusted voltage is used for charging the battery. By adopting the technical scheme, the charging state of the battery during charging can be improved.
In an exemplary embodiment, after the step S206, the method further includes: and under the condition that the target charging strategy is to charge the battery by using the voltage obtained by carrying out step-up and step-down processing on the output voltage, adjusting the output voltage of the charging equipment to the target voltage by using a step-up and step-down module, and charging the battery by using the target voltage, wherein the target voltage is the charging voltage, or the difference value between the target voltage and the charging voltage is smaller than a preset threshold value.
As an alternative example, the output voltage of the charging device may not be able to be adjusted to the charging voltage due to the buck-boost module itself, in which case the buck-boost module may be instructed to adjust the output voltage of the charging device to a target voltage, where the difference between the target voltage and the charging voltage is less than a preset threshold.
By adopting the technical scheme, when the universal charger is used for charging the battery, the battery can also reach the optimal charging state.
In an exemplary embodiment, charging the battery using the voltage obtained by step-up/step-down processing the output voltage includes the following steps S1 to S3:
step S1: under the condition that N batteries are charged in parallel by using the charging equipment and are of the same type, sequencing the N batteries according to electric quantity to obtain a battery sequence, wherein the electric quantity of an ith battery in the battery sequence is smaller than the electric quantity of an ith+1th battery, i is a positive integer larger than or equal to 1 and smaller than N, and N is a positive integer larger than 1;
step S2: and repeatedly executing the following step S3 until the electric quantity of each of the N batteries is equal, and simultaneously charging the N batteries by using the voltage obtained by carrying out the step-up and step-down processing on the output voltage.
As an alternative example, the voltage for simultaneously charging the N batteries may be obtained by performing a step-up/step-down process on the output voltage according to the charging voltage commonly determined by the battery information of the N batteries.
Step S3: and charging each of the 1 st to i th batteries by using the voltage obtained by performing the step-up and step-down processing on the output voltage until the electric quantity of each of the 1 st to i th batteries is equal to the electric quantity of the i+1th battery, wherein when each of the 1 st to i th batteries is charged, all of the i+1th to N th batteries are forbidden to be charged, and when each of the 1 st to i th batteries is charged, the electric quantity of each of the 1 st to i th batteries is equal.
As an alternative example, the voltage at which the 1 st to i th batteries are charged simultaneously may be obtained by performing a step-up/step-down process on the output voltage according to the charging voltage commonly determined from the battery information of the 1 st to i th batteries.
As an alternative example, since the electric quantity of the battery has a relatively small influence on the charging voltage, the voltage for simultaneously charging the 1 st battery to the i-th battery and the voltage for simultaneously charging the N-th battery may be obtained by performing a step-up/step-down process on the output voltage according to the charging voltage determined from the battery information of any one of the N-th batteries.
That is, in this embodiment, when N identical batteries are charged at the same time, the N batteries may be ordered from low to high in terms of electric quantity, resulting in a battery sequence. And then the electric quantity of the battery with the lowest electric quantity is charged to be equal to the electric quantity of the battery with the next lowest electric quantity, then the two batteries are charged simultaneously, and so on until the electric quantity of N batteries is the same, and then the N batteries are charged simultaneously.
In this embodiment, when N identical batteries are charged in parallel, the charging efficiency can be improved by adopting the above manner.
In an exemplary embodiment, in a case where N batteries are charged in parallel at the same time using the charging device and any two of the N batteries are different types of batteries, determining the charging voltage of the battery according to the battery information includes: determining the charging voltage corresponding to each battery according to the battery information of each battery in the N batteries; the determining a target charging strategy adopted for the battery according to the judging result of whether the difference is within a preset range from at least two charging strategies includes: and determining a target charging strategy adopted for each of the N batteries from at least two charging strategies according to a judging result of whether the difference value between the charging voltage corresponding to each of the N batteries and the output voltage is within a preset range.
That is, in this embodiment, when the charging device charges N different types of batteries at the same time, the charging voltage corresponding to each battery may be determined according to the battery information of each battery, and then the difference between the charging voltage corresponding to each battery and the output voltage may be determined, and different charging strategies may be selected for each battery according to the determination result of whether the difference is within the preset range. If a charging strategy of a battery is to charge the battery by using the voltage obtained by performing the step-up and step-down processing on the output voltage, the output voltage needs to be adjusted to the charging voltage corresponding to the battery by the step-up and step-down module corresponding to the battery, and then the battery is charged by using the charging voltage.
As an alternative example, each of the N batteries corresponds to a different charging circuit, and there is a step-up and step-down module in each charging circuit, for performing step-up and step-down processing on the output voltage of the charging device.
In this embodiment, when one charging device is used to charge N different types of batteries simultaneously, a corresponding charging policy may be provided for the different types of batteries, so that each battery may reach an optimal charging state.
In an exemplary embodiment, the battery power may be read during the process of charging the battery, and the battery power may be displayed through the display.
Through the steps, the charging voltage of the battery is determined according to the battery information of the battery to be charged, and the target charging strategy adopted for the battery is determined from at least two charging strategies according to the difference value between the charging voltage of the battery and the output voltage of the charging equipment, wherein the charging state of the battery under the charging voltage is the best, and the at least two charging strategies comprise: and charging the battery by using the output voltage of the charging equipment, and charging the battery by using the voltage obtained by carrying out step-up and step-down processing on the output voltage. By adopting the technical scheme, the charging equipment can adopt a corresponding charging strategy aiming at the battery information of the battery, so that the charging state of the battery during charging is improved, and the problem that the battery is easy to be in a poor charging state due to the fact that the charging equipment charges the battery in a fixed charging mode is solved.
In order to better understand the technical solutions of the embodiments and the alternative embodiments of the present invention, the flow of the above-mentioned determination method of the charging policy is explained below with reference to examples, but the flow is not used to limit the technical solutions of the embodiments of the present invention.
In an alternative example, fig. 3 is a charging circuit diagram according to an embodiment of the present application; as shown in fig. 3, the TYPE-C interface is an input port (i.e., a discharge port of the above-mentioned charging device), and the current passes through the switch 1, the ideal diode to the control switch 3 and the switch 4 of the battery (the switch 3 and the switch 4 may be used to control the sequence of charging the battery), and finally to the battery terminal. The other path of TYPE-C interface is an input port, and current passes through the buck-boost module and the switch 2, and an ideal diode is connected to the control switch 3 and the switch 4 of the battery, and finally to the battery terminal. Wherein the microprocessor (a processor with a computing power smaller than a preset computing power) controls the opening and closing of all switches. The buck-boost module is in communication connection with the microprocessor, the battery is in communication connection with the microprocessor, and the microprocessor is in communication connection with the protocol chip. A specific connection is shown in fig. 3.
It should be noted that, the communication modes of the microprocessor, the battery, the protocol chip and the buck-boost module are not limited in the application. Fig. 3 is merely an example, and the number of batteries to be charged is not limited to 2. The embodiment of the application does not limit the types of the lifting pressure module, the microprocessor, the protocol chip and the switch. The embodiment of the application does not limit the way of controlling the switch either. In an alternative example, the charging circuit may not require an ideal diode under certain conditions.
In order to better understand the above steps, in an exemplary embodiment, fig. 4 is a flowchart (two) of a method for determining a charging policy according to an embodiment of the present application, and in conjunction with the circuit diagram in fig. 3, a specific operation flow is as follows:
step S401: the charging system is in a standby state;
step S402: the microprocessor turns off all the switches, and after detecting the battery access, the microprocessor reads the battery information of the corresponding charging circuit respectively;
step S403: enabling a protocol chip by the microprocessor according to the information of the battery, and reading the output voltage of the adapter (namely the charging equipment in the embodiment) by the microprocessor through the voltage-lifting module after the protocol chip has a good voltage;
step S404: determining whether the output voltage is within a preset range, if so, proceeding to step S405, otherwise proceeding to step S406;
step S405: the microprocessor turns on the switch 1 and confirms that the switch 2 is turned off; then charging each battery according to the charging logic of the multi-path rechargeable battery, and simultaneously reading the charging state of the battery;
when the switch 1 is turned on and the switch 2 is turned off, the output voltage of the adapter is directly used to charge the battery, and the step-up and step-down module is not needed to perform step-up and step-down processing.
