A boost-topology battery charger powered from a solar panel Download White Paper 185Ko

Solar charging of batteries has recently become very popular. A solar cell's typical voltage is 0.7 V. Many panels have eight cells in series and are therefore capable of producing 5.6 V at most. This voltage is adequate for charging a single Li-ion battery, such as that used in cell phones, to 4.2 V with a buck or step-down charger. However, using the same panel to charge a multicell Li-ion battery like that used in laptop computers requires a boost or step-up charger. This paper identifies the key concerns in implementing such a modification and provides a design example that uses the Texas Instruments bq24650 solar battery charger.

This month, Cherry is giving away five of its Energy Harvesting Evaluation kits, worth over 266 Euros each, for EETimes Europe's readers to win. Cherry's energy harvesting technology benefit mostly applications where a complex wire assembly and/or batteries would be inappropriate.

The required RF-energy is created by the mechanical actuation of the switch and the data is transmitted wirelessly using RF-technology. The technology is very easy to install, fit and forget, with two standardised package versions for industrial applications: a rocker switch for actuation by hand and a snap-action switch for mechanical actuation.
