Abstract
This paper proposes new solar battery chargers for NiMH batteries. First, it is shown that existing charge-control methods can fail when charging by solar arrays in changing environmental conditions. This article discusses the reasons for the failure and introduces new voltage and temperature-based charge- control techniques. To increase charge speed, a maximum power point tracker is also implemented within the micro-controller of the proposed charger.
