Battery.Parameters

Define battery equivalent circuit parameters

Description

Use the Battery.Parameters object to define the battery equivalent circuit parameters. Battery.Parameters objects are contained in the Battery.PulseSequence and Battery.Pulse objects. The pulse sequence estimation sets some of the Battery.Parameters properties. You can override the properties by manually setting the properties. The number of pulses, N, in the dataset determines the length of each array.

Creation

Syntax

paramObj = Battery.Parameters

Description

MATLAB creates a paramObj = Battery.Parameters object that defines the battery equivalent circuit parameters.
