Embodiment 1

[0024] The specific circuit control mode of this embodiment is as follows, as Figure 3 to Figure 7 shown. The solar energy input parallel circuit module 10 includes three input interfaces J1, J2, J3, and anti-reverse diodes D1, D3, D5 are respectively connected to the positive terminals of the power supply, and they isolate the solar energy input from the input interface 1 and connect them to the common mode inductor On L2, at the same time, a large capacitor is connected to stabilize the front-end input.

[0025] The system power supply module 20 takes power directly from the rear end of solar energy input, and forms a step-down conversion circuit (Buck circuit) through triodes Q1, Q2, Q3, Q4, inductor L1, diodes D2, D4 and voltage regulator tube D7, and converts the input voltage to Stable to 12V to provide power for the DC / DC chip, the system power supply 20 is converted to 5V and 3.3V by the U1, U2 chip KB7550 and LM1117 conversion circuit, and supplies power to the char...

Embodiment 2

[0030] Example Figure 1-7 The shell of the box body 1 is an aluminum shell with a size of 135mm*97mm*45mm. The surface is anodized to achieve a certain anti-salt spray corrosion effect. It is equipped with three sets of flexible thin-film solar cell modules. The power is 100W. It is foldable and portable, suitable for field use . The plug-in PV input interface 2 is plugged with a multi-dimensional folded flexible solar cell module or a DC power supply provided by other transmitters.

[0031] How this charger works

[0032] The system power supply module 20 takes power directly from the rear end of the solar input, and stabilizes the input voltage to 12V through the Buck circuit composed of transistors Q1, Q2, Q3, Q4, inductor L1, diodes D2, D4, and voltage regulator tube D7, which is DC / DC The chip provides power, and through KB7550 and LM1117 power IC, it is converted to 5V and 3.3V as the working power of IC.

[0033] The solar maximum power tracking circuit module 30 ad...

Embodiment 3

[0038] See Figure 1-7 , when the digital tube displays "5L" after the controller system of the present invention is started, the user can cycle select the battery type by short pressing the button (within 3 seconds) (the digital tube flashes at 1HZ during the selection process); by long pressing the button (greater than 3 seconds) to determine the battery type, after confirming the battery type, the digital tube stops flashing and displays the battery type for 10 seconds; then displays the remaining charging time, check the battery type: long press the button (more than 3 seconds) during charging to display the battery type.

[0039] The battery type and the corresponding digital tube display are as follows:

[0040] 1. The 7.2V lithium-ion battery has a capacity of 1-2AH, and the digital tube displays: "L1"

[0041] 2. The 14.4V lithium-ion battery has a capacity of 10AH, and the digital tube displays: "L2"

[0042] 3. The capacity of the 12V alkaline storage battery is le...

Abstract

The invention discloses a portable solar charger capable of charging batteries of mobile equipment, belongs to the technical application field of solar batteries, and aims to equip a universal photovoltaic charging controller for battery development of portable communication equipment. The solar charger capable of charging various batteries is mainly characterized in that an IC (integrated circuit) module mounted in a box body comprises an MCU (microprogrammed control unit)-controlled MPPT (maximum power point tracking) solar maximum power output charging unit, a DC / DC control unit, a voltage and current detection unit, and a display and warning unit. Multidimensional folded flexible solar battery components or other power supplies are plugged in plug-in PV input interfaces; the battery types, voltage and capacities controlled by the rear end are various; and the front end adopts photovoltaic input, so that maximum photovoltaic input when the charger is used for batteries with different voltage can be achieved. The controller is applied in a field environment, has good water resistance, and is concise in display and convenient to operate and carry.

Description

technical field [0001] The invention relates to a portable solar charger, which can be used for charging batteries of mobile devices, and belongs to the application field of solar battery technology. Background technique [0002] At present, there are more and more types of portable mobile devices and more and more applications, and the types and specifications of batteries that provide energy for them are also increasing. Although there are a variety of battery chargers on the market, there are very few solar chargers or PV chargers that specialize in different charge control processes for different types of batteries. Especially for outdoor mobile communication equipment, outdoor meteorological environment monitoring, scientific research, earthquake relief, tourism and other civilian uses are in demand. The Chinese patent "A Portable Solar Power Generation System" ZL201220119735.2 integrates charging control, battery, and inverter into one body, but its volume and weight ...
