Many IoT devices rely on small non-rechargeable power supplies and cannot be a long-term use. Furthermore, the existing light energy charging devices couldn’t meet the requirements that limit the application of the IoT.
As a developer of high-efficiency PV energy harvesting, for accelerating the speed of customized product development, we innovated the light energy harvesting module of the Micro Energy Harvester Test Kit. Our customers can skip through POC(Proof Of Concept) and enter EVT(Engineering Verification Test) directly.
With Flexwave unique waveguide PV and specially developed MPPT power manager would become a complete IoT energy solution. This solution has also been awarded high-efficiency solution label which issued by Solar Impulse foundation(a non-profit organization based in Switzerland). Today, as the smallest PV energy harvesting module of Flexwave: Micro Energy Harvester Test Kit, we are truly looking forward to supporting more IoT suppliers to solve the problem of insufficient power.
|Size (LxWxH)||58x48x12 mm with 3D printed ABS case|
|Pmax / Voc / Isc*||330mW / 2.56V / 165mA|
Embedded Power Manager
|Charging voltage||4.2V with CC-CV battery charging rule|
|Output voltage||w/ battery load = Voltage of battery (Vbat)
w/o battery load = 4.2V
|Battery level control||System output closed at Vbat = 2.8V, and restart at Vbat = 3.6V|
|Peak output current||220mA|
|Type of Connector||Molex/jst 1.25mm pitch, Female|
|Daily power**||Sunny a：1,100mWh (3.7V / 297 mAh)；Cloudy：105mWh (3.7V / 28mAh)
Indoor b (800lux)：1.9mWh (3.7v / 0.5mAh) for 8hrs
|Note||* ：The Pmax was measured under the standard test condition with 1,000W/m2 irradiation and AM1.5G.
**：The daily power was measured at Hsinchu, Taiwan, the data will be different under various condition.
a：The sun intensity of a Sunny day is 1,000W/m2, a cloudy day is around 100W/m2
b：The power intensity of 800lux artificial lamp is about 1W/m2
