Abstract
In accordance with one illustrative embodiment, a system for determining a self-discharge current characteristic of a storage cell (or a bank of storage cells) includes a voltage source, first and second voltage measurement circuits, a current measurement circuit, and a processor. The voltage source provides a potentiostat voltage to the storage cell coupled to the system. The first voltage measurement circuit provides a first voltage resolution for measuring an open circuit voltage across a pair of terminals of the storage cell. The second voltage measurement circuit provides a second voltage resolution that is significantly higher than the first voltage resolution for measuring a terminal voltage at one of the pair of terminals of the storage cell. The processor executes a test procedure by using the voltage source, the first and second voltage measurement circuits, and the current measurement circuit, to determine the self-discharge leakage current characteristic of the storage cell.
