1. A method for predicting the remaining life of a battery for a vehicle comprising:
- obtaining a value representative of the amount of remaining life for a battery in a new and fully charged state;
monitoring at least one parameter of the battery during use of the battery;
obtaining an acceleration factor for the at least one monitored parameter; and
estimating the amount of life lost from the battery utilizing the acceleration factor;
whereby the estimation of the amount of life lost utilizes historical information relating to the use of the battery.

Abstract
A method for predicting the remaining life of a battery for a vehicle includes obtaining a value representative of the amount of remaining life for a battery in a new and fully charged state and monitoring at least one parameter of the battery during use of the battery. The method also includes obtaining an acceleration factor based on the at least one monitored parameter and estimating the amount of life lost from the battery utilizing the acceleration factor.

20. A method for monitoring a battery comprising:
-
obtaining an estimate of the time that a new battery will deliver a sufficient amount of power for a vehicle application;
monitoring the battery during use;
determining the amount of time that the battery has been in a first state during the use;
obtaining an acceleration factor for the first state;
adjusting the amount of time that the battery has been in the first state utilizing the acceleration factor; and
subtracting the adjusted amount of time from the estimate to obtain an estimate of the remaining time that the battery will deliver a sufficient amount of power for a vehicle application. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method for monitoring a battery for a vehicle comprising:
-
obtaining an input signal representative of an estimate of the amount of life remaining for a new battery;
obtaining input signals during use of the battery that are representative of states of the battery;
determining the amount of time the battery is at a first state;
determining the amount of time the battery is at a second state;
obtaining a first acceleration factor for the first state and a second acceleration factor for the second state;
applying the first acceleration factor to the amount of time the battery is at the first state to provide a first adjusted amount of time;
applying the second acceleration factor to the amount of time the battery is at the second state to provide a second adjusted amount of time; and
subtracting the first adjusted amount of time and the second adjusted amount of time from the estimate to provide an adjusted estimate of the remaining life of the battery. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38)
