What is solar charger?
It refers the device charging the secondary battery by converting the solar energy into the electric energy by using the solar battery, which is a semiconductor device.
Configuration
- * Generating panel : olar battery module
- * Control panel : DC/DC converter
- * Storage battery: : secondary battery
Charging method
- PWM(Pulse Width Modulation) method
- Continuous charging method
-
Pocket Type Solar Charger
(2.5watt ~ 10watt)Military personal cellular phone, ADU-95K, PRC-96K, position reporting equipment, etc. (small walkie-talkie), direct charging type, internal storage battery installed type
-
Radio Attached Solar Charger
Charging while moving by being attached to the back of the radio (PRC-999K, PRC-950K) Direct charging type, internal storage battery installed type
-
Stationary Multiple Power Supply Solar Charger
(16watt ~ 128watt)Used in all field wire/wireless communication equipment
Features
- Operating voltage : 3.6–28volt, etc. * Conversion to 3.6, 6.0, 12, 16, 24, 28volt depending on the device
- Operating temperature : - 10–70℃ * Available at -40–80℃ depending on the field environment.
- Basic color : khaki, speckled pattern in khaki, etc. * Color can be selected in accordance with the camouflage condition.
General features
-
The highest output per unit area
21.5% of conversion efficiency of solar battery of SunPower in the United States is the highest efficiency among the commercialized solar battery, and the solar battery of SunPower is used.
-
It is produced to minimize the light reflection of exposed surface.
Electrode does not reflect the light since the electrode of solar battery, the major reflector, is located at the back. Especially, exposed surface of solar battery plate is made with non-reflecting film, which does not have a risk of exposure of location while using it in the field.
-
It can be operated normally although the part of solar battery plate is damaged.
Since the solar battery plates are connected in parallel as a whole or partially, the charger operates normally although the part of solar battery plate is damaged or covered by the shade.
Therefore, only the electric current is decreased as much as the number of damaged solar battery plate, while operating voltage is not changed.
-
Parallel expansion of solar battery is available depending on the required electric power.
Solar battery plate can be connected in parallel to meet the required amount of electric power for field device.
-
Solar battery plate can be produced for any type of portable field devices.
All operating voltages and electric current can be fulfilled by adjusting the number of series and parallel connection of solar battery in the solar battery plate.
-
Usage in any time during the day or night is available if internal storage battery is used. If internal storage battery is installed, it can be used regardless of the presence of sunlight, and various selections of capacity of internal storage battery are available depending on the applicable device.
Amount of generation per unit area is excellent, and the conversion of charger depending on the communication device is easy.
Based on the features above, it will be applied to the general mobile devices and composed with more practical design.
