P2110-EVAL-02 Lifetime Power Energy Harvesting Development Kit for Battery Charging Users Manual - featuring THINERGY Micro-Energy Cell 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. Powercasts 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 Fixed, regulated output voltage battery voltage until the configured maximum output voltage is reached Usage Direct power OR Pulsed power OR Battery-charging (direct Battery-charging (additional connection to typical battery)* circuitry typically required) Operating / Charging Range Shorter roughly half as far as Longer roughly twice as far as (with identical antennas) the P2110. 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.
