Abstract
A lithium-based battery system for a vehicle includes a plurality of lithium battery cells arranged in series that provide energy to propel the vehicle. Each of the battery cells includes a first terminal, a second terminal, a plurality of lithium battery elements arranged in parallel, a plurality of disconnect switches, and a shunt switch. Each of the battery elements includes a first terminal and a second terminal. The first terminal of each of the battery elements is connected to the first terminal of the battery cell. The second terminal of each of the battery elements is connected to the second terminal of the battery cell via a corresponding one of the disconnect switches. The shunt switch is connected between the first and second terminals of the battery cell. A control module selectively opens and closes the shunt switches and the disconnect switches.
