First Claim
Patent Images
1. A method of determining the kind of a given battery in an automotive vehicle, the method comprising:
- obtaining a first set of battery parameters corresponding to the given battery;
comparing the first set to predetermined sets of known battery parameters respectively corresponding to known batteries to obtain respective comparison values for each of the known batteries, the comparison value of each known battery indicating an amount of matching between the first set and the set of known battery parameters corresponding to the known battery, wherein each known battery has at least one characteristic; and
determining the kind of the given battery to be of the same kind as the known battery associated with the comparison value having the largest amount of matching and thereby determining a characteristic of the given battery to be same as the characteristic of the known battery.

Abstract
A method and system is disclosed for determining the kind of a battery in an automotive vehicle. Based on obtaining a set of battery parameters corresponding to the battery in the automotive vehicle, the set of battery parameters is compared to a number of predetermined sets of known battery parameters to obtain respective comparison values. Based on at least one of the comparison values, the kind of battery in the vehicle is determined to be of the same type and capacity as a known kind of battery that corresponds to one of the predetermined sets of known battery parameters.

15. A method of determining the kind of a given battery in an automotive vehicle, the method comprising:
-
obtaining a first set of battery parameters corresponding to the given battery based on the voltage, current, and temperature levels of the given battery during at least two states of the given battery; comparing the first set to predetermined sets of known battery parameters to obtain respective comparison values, the predetermined sets respectively corresponding to known batteries having at least one characteristic, and the comparison values indicating an amount of matching between the first and predetermined sets; and determining the kind of the given battery to have the same characteristic as the known battery associated with the comparison value having the largest amount of matching and thereby determining a characteristic of the given battery to be same as the characteristic of the known battery.

16. A system for determining the kind of a given battery in an automotive vehicle, the system comprising:
-
a voltage sensor for generating a voltage signal indicative of a voltage level across the given battery; a current sensor for generating a current signal indicative of a current level flowing from the given battery; a temperature sensor for generating a temperature signal indicative of a temperature level of the given battery; and at least one computer-based controller including a processor operable to execute software instructions, a computer memory operable to store software instructions accessible by the processor, and a set of software instructions stored in the memory to obtain a first set of battery parameters corresponding to the given battery; to compare the first set to predetermined sets of known battery parameters respectively corresponding to known batteries to obtain respective comparison values for each of the known batteries, the comparison value of each known battery indicating an amount of matching between the first set and the set of known battery parameters corresponding to the known battery, wherein each known battery has at least one characteristic; and to determine the kind of the given battery to be of the same kind as the known battery associated with the comparison value having the largest amount of matching and thereby determining a characteristic of the given battery to be same as the characteristic of the known battery. - View Dependent Claims (17, 18, 19, 20)
