Abstract
An apparatus is provided for testing a first storage battery in a bank of storage batteries, the bank formed of at least two storage batteries electrically coupled together. The apparatus includes a first Kelvin connection configured to couple to the bank of storage batteries, the first Kelvin connection including a first and second electrical connection and a second Kelvin connection configured to couple to the bank of storage batteries, the second Kelvin connection including a first and a second electrical connection, the first and second Kelvin connections configured to couple across at least the first battery. A time varying forcing function source is configured to apply a forcing function between the first electrical connection of the first Kelvin connection and the first electrical connection of the second Kelvin connection. A voltage sensor is configured to sense a voltage between the second electrical connection of the first Kelvin connection and the second electrical connection of the second Kelvin connection and provide a sensed voltage output which is at least partially a function of the forcing function. A current sensor senses an electrical current in the bank of stora…
