Abstract

The present application provides a battery management system for a lithium sulphur cell. The battery management system comprises a charging module configured to charge a lithium sulphur cell; and a logical module configured to control the charging module to charge the lithium sulphur cell to a shuttle reduction state of charge. The shuttle reduction state of charge is equal to or lower than a predetermined shuttle state of charge at which a first derivative of a state of charge of the lithium sulphur cell during charging with respect to one of time or charge is within a predetermined first derivative threshold of zero and at which a second derivative of the state of charge of the lithium sulphur cell during charging with respect to one of time or charge is within a predetermined second derivative threshold of zero at the same value of time or charge at which the first derivative is within the predetermined first derivative threshold of zero.
