According to an embodiment of the present disclosure, a power conversion device included in a power system may include a conversion circuit configured to transform a direct current (DC) voltage output from batteries, and a balancing circuit connected to a ...

A cell balancing current control device and method for a battery pack are capable of reflecting a resistance value depending on a length of a flat cable which connects each cell of a multi-series battery and a battery management system (BMS) (that is, cell...

A converter system, e.g., for vehicle-to-vehicle charging, includes galvanically-isolated modular first and second converters having the same maximum voltage rating, a direct current (DC) voltage bus interconnecting the converters, and an electronic contro...

An apparatus and method of balancing cells in a battery using an isolated power supply and pairs of switches to direct power to cells at a lower state of charge to bring them into balance with cells at a higher state of charge.
