Overview
The Lifetime Power
®
Energy Harvesting Development Kit for Battery Charging is a complete
demonstration and development platform for wireless battery-charging over distance powered by RF
energy (radio waves). This kit features a THINERGY
®
Micro-Energy Cell (MEC) from Infinite Power
Solutions (IPS) which has an ultra-thin form factor and extremely low leakage.
Batteries are charged by the P2110CSR Powerharvester
®
Chipset Reference Design, which converts RF
energy, stores it into an intermediate capacitor, and then provides a pulsed, regulated voltage output
which provides charge current to the attached storage. In this kit, the TX91501 transmitter is the source
of RF energy at 915MHz, but other sources from 850-950 MHz can also be used for power.
A regulated load voltage is provided to power an application device, and the Texas Instruments eZ430-
RF2500 wireless development tool is included for demonstration purposes.
Note:
This kit is based on the P2110CSR Powerharvester. Powercast’s P1110 Powerharvester component also
charges batteries and the main differences are as follows:
Parameter
P1110
P2110CSR
Charging Method
Continuous
Pulsed / Intermittent
Output Voltage Range
1.8V - 4.2V
2V – 5.5V
Output Voltage
Output voltage floats with the
battery voltage until the
configured maximum output
voltage is reached
Fixed, regulated output voltage
Usage
Direct power OR
Battery-charging (direct
connection to typical battery)*
Pulsed power OR
Battery-charging (additional
circuitry typically required)
Operating / Charging Range
(with identical antennas)
Shorter – roughly half as far as
the P2110.
Longer – roughly twice as far as
the P1110.
* P1110 is NOT to be used with thin-film batteries like THINERGY that require a fixed charging voltage.
The P1110 Evaluation Board kit (P1110-EVB) is also available to charge batteries using the P1110. The
P1110-EVB will receive power from the transmitter included with the P2110-EVAL-01 or P2110-EVAL-02
development kits.
