Traction Li-ion accumulator 28V/40Ah with internal protecting and control circuits Kovář, Robert ; Pazdera, Ivo (referee) ; Vorel, Pavel (advisor) This work is a design and construction solution for an inteligent charger of Li-Ion battery system.The system consists of an accumulator, built out of individual cells (serial-parallel sequence), protective and monitoring circuits and charger with control circuits. These control circuits of this charger collaborate with monitoring circuits. The base of this charger is a switching source (singlemode buck converter with transformer).The charger allows to supply relatively high power while sustaining small dimensions.(20A with 28V that´s 560W) Use of DC/DC converter is a base of charger and also delivers other benefits, such as high efficiency and easy control of output current.
