The name of this product is ‘Ultra high-efficiency power converter of the energy harvesting’ or ‘The lithium polymer for low input voltage/Lithium ion battery charger.’

This product(‘STORM6') can be used for the forms of piezoelectric power generation for the vibration, pressure, shock which is using the mechanical energy and the unit solar cell, thermoelectric generators by using the heat, it may be used such as power generation by using waste heat.

It is released to solve the problems such as abandoned before among weak powers came from piezoelectric elements, thermal elements, the temperature difference power generation device, unit cells like as solar cells or the things that they are not used due to the problems with power conversion efficiency.

With this product, you can save the energy which is converted to a high efficiency by converting the form of the available power. As the main power source for small electronic devices, the energy harvesting technologies can be used.

The STORM6 (The Ultra-Efficient Power Converter for Energy Harvesting) can be applied to the energy harvesting development element (piezoelectric element/ thermoelectric element/unit cell solar cell), energy harvesting come from the power which is generated from the energy harvesting source, internet of things, wearable, industrial monitoring device, environmental monitoring device, bridges and structures, etc. It is possible to use for all industry sectors such as wireless sensors which are necessary for the safety facilities monitoring devices.

-There are energy harvesting technologies currently being used as the primary power sources for small electronic devices, this product is available in the field which is applied as the essential product for its maximum efficiency.

-This product can be applied to the dangerous places such as high-pressure transmission towers and even the power of wireless sensor, you can apply this product when you use the energy harvesting in case of it is difficult to replace the battery due to the battery is hard to reach a position cumbersome wireless sensor.

In particular, in case of the wireless sensor which is using the energy harvesting, you can significantly reduce the battery replacement costs, and also you can monitor where you do not wear the sensor due to the power problems. For this purpose, it can be applied as a power converter for using the ultra high-efficiency energy harvesting.

For a typical power converter, the input voltage and current input should use more stable 5V voltage waveform and sufficient input current of mA ~ A units should be supplied. If the power supply is not done smoothly, there will be many limitations to use.

However, in case of STORM6, input voltage (0.13~3V, avg : 1.2V) and the electric current can be input hundreds to tens of mV ~ V through the wide range of voltage, the electric current or uA unit electric current can be input.  

Low input voltage Lithium Ion / Polymer Battery charger

FEATURES

- It can convert the very little voltage generated from the low

voltage output energy harvest generating element such as 1 solar

cell , piezo-electric element, thermoelectric generating element into

the voltage that can charge the battery to charge the lithium ion or

lithium polymer battery by the high efficiency.

- It uses the surrounding energy source although it is hard to supply

the existing power, and can use as the power device.

- In case of sunlight generation, it energy harvesting the surrounding

energy to generate in parallel although the generation quantity

decreases according to the climate change such as rainfall, sunset.
