Abstract
Time domain battery usage data of a battery of an electrified powertrain of a vehicle in terms of average SOC, DOD and a set including average current flow rate and average battery temperature for each charge-discharge full cycle and half cycle of the battery during a use period are used to identify a location in a 3-D storage matrix (of fixed size and predetermined discretization levels for each dimension) in memory of an electronic control unit and a count in that location incremented. In an aspect, the charge-discharge full cycles and half cycles are identified using four-point rainflow cycle counting.
