Degree :
To develop the battery algorithms – SOC, SOH and SOF configurable for battery chemistry and vehicle configuration,
studied common parameters which are same over the battery chemistry and vehicle configuration.
For Various battery chemistries, battery characterisation tests procedures recommended by international test standards
are almost same, even the parameters which are related to estimate SOC, SOH algorithm are also remain same. Example:
Battery capacity, OCV vs SOC characteristics, hysteresis characteristics, Resistance trend etc.
Battery algorithm directly uses these parameters and operating limits of the batteries as input to estimate the algorithm.
Methods being used in the algorithm for various chemistry is also same but the conditions, set point and look-up tables
makes the algorithm to respond in different way for various battery chemistries. Example: SOC algorithm – basic
common methods are used for many battery chemistries like Coulomb Counting, Direct and Book-keeping Combination,
Resistance based OCV estimation, SOC correction from OCV etc., SOH algorithm is estimated
