1. A vehicle comprising:
- a battery; and
at least one control module configured to apply a generally constant current to the battery for a period of time, to measure a response voltage of the battery to the applied current, to determine battery impedance parameters based on at least one of the applied current, period of time, and response voltage, and to determine a degradation condition of the battery based on the battery impedance parameters.

Abstract
A method for diagnosing a battery may include applying a generally constant current to the battery for a period of time, measuring a response voltage of the battery to the applied current, determining battery impedance parameters based on at least one of the applied current, period of time, and response voltage, and determining a degradation condition of the battery based on the battery impedance parameters.
