METHOD AND APPARATUS FOR CONTROLLING A DC/DC CONVERTER OF A BATTERY SYSTEM, AND COMPUTER PROGRAM PRODUCT

Abstract

A method for controlling a DC/DC converter of a battery system is disclosed. The method includes controlling the operating parameters of the DC/DC converter of the battery system based on the acquired stack current of the battery stack of the battery system, so as to regulate the phase current of the DC/DC converter. A first DC/DC conversion unit and a second DC/DC conversion unit are connected in parallel, in such a manner that: at least three operating intervals of the DC/DC converter are divided based on the acquired stack current of the battery stack, such that in each operating interval, the first DC/DC conversion unit and/or the second DC/DC conversion unit operate only in a single conduction mode, respectively. The conduction mode includes a continuous conduction mode and/or a discontinuous conduction mode. The method also includes, based on the conduction mode of the first DC/DC conversion unit and/or the second DC/DC conversion unit, selecting the first phase current of the first DC/DC conversion unit or the second phase current of the second DC/DC conversion unit as the AC injection current of the battery system.
