Photovoltaic Harvesting

Photovoltaic Harvesting

Let’s assume that you work with battery powered IoT wireless devices that operate under light sources that may come from sun, light bulb, tube, etc. You need to replace the batteries of those devices, because they run out of energy. This generates operational costs.

But, most probably, there is enough of energy in the light surrounding your devices that you could use to power them.

Depending on the lighting conditions (low light indoor conditions to bright sunny outdoor conditions), traditional photovoltaic (PV) cells can generate from .

When properly selected (material and topology) and sized (illuminated area), a PV cell combined with our state of the art energy harvesting PMICs will recharge the batteries of your IoT applications from ambient light.

Using e-peas’ photovoltaic energy harvesting, you will avoid typical operating costs associated with battery replacement.

AEM10941 – Energy Harvesting Power Management IC

E-peas’ photovoltaic energy harvesting IC solution – AEM10941 – is the next generation integrated energy management subsystem that extracts DC power from up to 7 cells solar panels to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages. This allows product designers and engineers to extend battery lifetime and ultimately get rid of the primary energy storage element in a large range of wireless applications like industrial monitoring, home automation, wearables.

The AEM10941 harvests the available input current up to 125 mA. It integrates an ultra-low-power Boost converter to charge a storage element, such as a Li-Ion battery, a thin film battery or a super- or conventional capacitor. The Boost converter operates with input voltages in a range of 50 mV to 5V. With its unique cold-start circuit, it can start operating with empty storage elements at an input voltage as low as 380 mV and an input power of just 3 µW.

The low voltage supply typically drives a microcontroller at 1.8 V. The high voltage supply typically drives a radio transceiver at a configurable voltage. Both are driven by highly efficient LDO (Low Drop-Out) regulators for low noise and high stability.

Configuration pins determine various operating modes by setting predefined conditions for the energy storage element (overcharge or overdischarge), and by selecting the voltage of the high voltage supply. However, special modes can be obtained at the expense of a few configuration resistors.

The chip integrates all the active elements for powering a typical wireless sensor. With only seven external components, integration is maximum, footprint and BOM are minimum, optimizing the time-to-market and costs of WSN designs in all markets.

Five identical capacitors and two inductors are required, available respectively in the small 0402 and 0603 SMD formats.

RF Harvesting

RF Harvesting

Let’s assume that you work with battery powered IoT wireless devices that operate within wireless waves rich environments. Without energy harvesting, you need to replace the batteries of those devices, because they run out of energy. This generates operational costs.

But there might be enough of energy provided by the wireless emitters surrounding your devices that you could use to power them.

Those emitters include:

And if not, you can equip the environment with dedicated emitters emitting power at 868MHz (Europe) or 915MHz (USA).

Depending on the power emitted by the source and the distance from the source (from 10’s of cm up to 15m), typical power levels you can harvest range from 10µW to mWs.

When properly selected and sized (frequency compatibility with available sources), an antenna and a balun (provided by e-peas for all above mentioned frequency ranges) combined with our state of the art energy harvesting PMICs will recharge the batteries of your IoT applications from ambient RF power.

Using e-peas’ RF energy harvesting, you will avoid typical operating costs associated with battery replacement.

Thermal Harvesting

Thermal Harvesting

Let’s assume that you work with battery powered IoT wireless devices that operate in an environment presenting thermal gradients generated by heater, human body, furnace, motor, etc. Without energy harvesting, you need to replace the batteries of those devices, because they run out of energy. This generates operational costs.

But, in some environments, there is enough of energy dissipated by surrounding machines that you could use to power your devices.

Depending on the available temperature gradients, TEGs can generate from .

When properly selected (material and topology) and sized (area exposed to temperature gradients), a TEG combined with our state of the art energy harvesting PMICs will recharge the batteries of your IoT applications from hot or cold sources.

Using e-peas’ thermic energy harvesting, you will avoid typical operating costs associated with battery replacement.
