Abstract

We use DSP to construct an intelligent Lithium-ion battery charging system. By adopting this intelligent charging system, we perform the data collection, calculation and peripheral circuit control for the battery charging status. According to the lithium-ion battery charging specifications, two hours are required for battery charging. A fuzzy controller constructed using the battery protection voltage and voltage difference among the batteries is used as the input variable to shorten the charging and equalizing time and assure that the battery will be operated within the safety voltage range.
