A lithium ion battery charger based on a partially concentrated photovoltaic device

Abstract

With the increase of electronic gadgets each may hold globally and the increase in usages, charging of the lithium ion batteries is increasing in demand as well. With the introduction of external battery power banks, more electricity is used as they require AC power source to charge.

This trend of using high capacity battery banks made the demand of electricity higher as it

continues. With the global oil reserve slowly depletes and burning of oil being the primary

energy source used for electricity generation, alternative source of energy have been explored

such as solar, wind, tidal and nuclear to produce electricity. On top of that, the combustion of

fossil fuel causes pollution and will continue to worsen global warming.

For situations where AC power is not readily available and for electricity cost saving purpose, it

is useful to devise a solar based battery charger. Out in the market there are already solar

chargers, but this design will be based on a concentrated solar photovoltaic device with an

optical concentrator to charge the battery.
