Abstract:
1. A vehicle system comprising: a battery pack comprising a plurality of subdivisions; a measurement system communicatively coupled to the battery pack configured to determine a first plurality of subdivision electrical parameters, each subdivision electrical parameter of the first plurality of electrical parameters being associated with one subdivision of the plurality of subdivisions; a calculation system communicatively coupled to the measurement system configured to calculate a plurality of derivative values over a first portion of a life of the battery pack based upon the first plurality of subdivision electrical parameters, to calculate a first summation value based on the plurality of derivative values and to calculate a second summation value based on a plurality of derivative values associated with a second electrical parameter over the first portion of the life of the battery pack; and a battery control system communicatively coupled to the calculation system, the battery control system configured to generate a command configured to control an aspect of an operation of the battery pack, the control command being generated at least in part based upon the first summation value and the second summation value.
