Abstract
A method and circuit for balancing energy levels among first and second battery groups within a battery pack are provided. The first and second battery groups are connected across a first current bus that may, for example, provide power for an electric motor of an electric vehicle. The first battery group is also connected across a second current bus that may, for example, provide current to vehicle electrical systems such as lighting systems. The method includes the steps of generating a first state of charge value indicative of a first energy level in the first battery group and generating a second state of charge value indicative of a second energy level in the second battery group. The method also includes the step of controlling the first energy level responsive to the first and second state of charge values.
