Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments.
The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments can be mutually combined and referred to without contradiction.
A first embodiment of the present application relates to a charging method applied to a charging device, the charging device includes a plurality of charging modules having the same structure, each of the charging modules includes at least a microprocessor, a switching module, and a photosensor, and a duty ratio of the switching module is controlled by the microprocessor.
The specific flow of the charging method is shown in fig. 1.
Step 101, obtaining the maximum power duty ratio of the charging module, where the maximum power duty ratio is the duty ratio of the switch module in the charging module when the charging power of the charging module in the charging device is maximum.
The charging device is composed of a plurality of individual charging modules, the charging modules are identical in structure and at least comprise a microprocessor, a switch module and a photoelectric sensor, the type of micro-processing is not limited, in this embodiment, an MCU is taken as an example, the MCU is used for controlling the duty ratio of the switch module, and the switch module comprises a plurality of transistors. The duty cycle is the proportion of the energizing time relative to the total time in a pulse cycle, assuming the element is an electronic valve, when the circuit is fully on, the valve is fully open; when the duty cycle is 50%, the valve state is half open. Similarly, when the duty cycle is set to 20%, the opening of the valve should obviously be 20%. Thus, the valve can be arbitrarily adjusted in the range of 0% (fully closed) to 100% (fully open).
When charging is carried out through the solar cell panel, the charging efficiency is highest when the charging power is the largest, the speed is the fastest, but the opening degree of the MOS tube control switch is uncertain under what circumstances, and if a traditional mode of connecting a plurality of different charging structures is adopted, the algorithm of each single charging module needs to be controlled, and different modules have different algorithms, so that the research and development period of finding the maximum output power of the whole device can be longer.
In this embodiment, the charging modules have the same structure, and when the transistor duty cycle corresponding to the maximum output power of one charging module is found, the duty cycle is applied to all the charging modules, so that the entire charging device has the maximum charging power.
The method for obtaining the duty ratio corresponding to the maximum power is specifically shown in fig. 2:
the total N charging modules are arranged, and all the charging modules are placed under the condition that illumination is the same, so that illumination intensity and initial voltage of each module are ensured.
S201, acquiring the number of charging modules as N.
S202, the duty ratios of the switch modules in the charging modules are respectively set according to the first proportion, and the corresponding duty ratios of the charging modules are different.
The duty ratios of the switching modules of the N charging modules are configured to be 0-100%, respectively, PWM 1=0%, PWM 2= (100/N)%, PMW 3= (200/N)% … … pwmn=100%, for example, N is 4, and the duty ratios of the 4 charging modules are 0%, 25%, 50%, 100%, respectively.
The MCU in each charging module is controlled by the main control MCU, so that the duty ratio of the transistor of each charging module is an expected value.
Further, the main control MCU may be an independent MCU other than the charging module, or a charging module in the charging module group may be set as a main control charging module, and an MCU in the main control charging module is a main control MCU.
S203, judging whether the number of the charging modules is larger than a preset value.
If the value is less than or equal to the preset value, executing step S204;
if the value is greater than the preset value, step S206 is performed.
For example, when N is greater than 10, it indicates that the number of charging modules is sufficiently large, and a duty cycle corresponding to the maximum power that is relatively accurate can be obtained, that is, the greater the number of charging modules, the more accurate the maximum power duty cycle.
When N is less than or equal to 10, the number of charging modules is smaller, and the duty ratio corresponding to the maximum power calculated for the first time is not accurate enough, so that the second configuration and calculation are performed on the duty ratios corresponding to the maximum power and the second maximum power, as shown in S205.
S204, comparing the output power of each charging module, and determining a first duty ratio corresponding to the charging module with the largest output power and a second duty ratio corresponding to the charging module with the second largest output power.
The maximum output power is Pmax, and the first duty ratio corresponding to the charging module with the maximum output power is PWMx; the second maximum output power Psec and the second duty cycle corresponding to the second maximum output power charging module are PWMs.
Fig. 3 is a circuit schematic of the charging device in the present embodiment. As shown in fig. 3, a resistor R1 is used to limit the current in the charging line in series and can be used to calculate the output power.
When PMOS (Q2, Q3) is on: ADC1 of MCU detects voltage V1 on left side of resistor R1; the ADC2 of the MCU detects the voltage V2 of the battery on the right side of the resistor R1.
When PMOS (Q2, Q3) is off: ADC2 of MCU detects voltage V2x of battery on right side of R1.
The power of each charging module is pn= (V1-V2) ×v2×pwmn/R1.
S205, setting the duty ratio of the switch module in each charging module to be a first duty ratio to a second duty ratio according to a second proportion, wherein the corresponding duty ratio of each charging module is different.
Taking n=4 as an example, assuming that the duty ratio corresponding to the charging module of the output power PWMx is 100% and the duty ratio corresponding to the charging module of the output power PWMs is 50%, the duty ratios of the charging modules are respectively set to be 50%, 62.5%, 75%, 100%. And respectively calculating the power of each module at the corresponding duty ratio.
The first ratio and the second ratio in S202 and S205 may be the same ratio or may be different ratios, and the method of dividing the duty ratio value of each charging module is not particularly limited by taking the same ratio as an example.
S206, comparing the output power of each charging module, and determining the duty ratio corresponding to the charging module with the maximum output power.
S207, taking the duty ratio corresponding to the charging module with the largest output power as the maximum power duty ratio;
and 102, controlling the duty ratio of the switch module of each charging module in the charging device to be the maximum power duty ratio so as to charge.
The duty cycle of the transistor in each charging module in the entire charging device is set to the maximum power duty cycle so that each charging module has the maximum charging power, thereby making the entire charging device have the maximum power.
Further, as shown in fig. 3, S1 is a digital photoelectric sensor, when the ratio of the increase or decrease of the intensity of the illumination received by S1 exceeds a preset light intensity threshold, the processes from step 101 to step 102 are repeatedly performed, that is, when the light intensity changes more severely, the input power of the solar panel at this time has changed, so that the maximum output power and the duty ratio corresponding to the maximum output power need to be recalculated. For example, when the light sensation value is detected, if the light sensation value is found to increase or decrease by more than 500LUX, the maximum output power and the duty ratio corresponding to the maximum output power are recalculated.
Similarly, when the fluctuation ratio of the voltage V2x in the circuit exceeds the preset voltage fluctuation ratio threshold, if the voltage is increased or decreased by 5%, the maximum output power and the duty ratio corresponding to the maximum output power are recalculated.
In fig. 3, U1 is a high-efficiency solar panel; q2 and Q3 are PMOS; q1 is NMOS; u2 is MCU; s1 is digital light sensation; r1 is a resistor; and a 2PIN battery interface is connected with the battery U3. GPIO_1 of U2 controls Q1, when GPIO_1 outputs high, G poles of Q2, Q3 are pulled to ground, Q2, Q3 are opened; when the gpio_1 output is low, Q2, Q3 are turned off, where Q3 is aimed at preventing reverse current flow. S1, transmitting data of illumination intensity to an MCU (micro control Unit) through a serial port by a digital photoelectric sensor; r1 is a resistor for limiting current in series in the charging line and can be used to calculate output power.
Compared with the related art, the embodiment of the application connects a plurality of identical charging modules for charging, is different from the traditional method of using a plurality of different charging structures, can use the optimal duty ratio of the transistor without adjusting algorithms according to different structures so as to realize the maximum charging output power, and applies the duty ratio to each charging module, thereby saving the research and development period and the calculation period, enabling a set of algorithms to be applied to charge a plurality of charging modules at the same time, increasing the charging efficiency, accelerating the charging speed, and increasing or reducing the number of the charging modules as required without affecting the algorithm for obtaining the maximum output power, and facilitating the updating of the charging equipment. And the illumination intensity is monitored by the photoelectric sensor, and when the illumination intensity is changed greatly, the duty ratio is dynamically adjusted, so that the charging device is charged under the maximum output power.
