battery_charging: Charging time of a lithium-ion battery.

In industRial: Data, Functions and Support Materials from the Book "industRial Data Science"

Description

A data set with charging time in hours required to recharge a lithium-ion battery based on a full factorial design of experiment with four variables (A, B, C, D) coded as +/- 1. Design effects are coded as numerical variables in order to allow to build models without coding the contrasts and then to make predictions on a continuous range from -1 to +1.

A

Variable A (numerical)

B

Variable B (numerical)

C

Variable B (numerical)

D

Variable B (numerical)

Replicate

The independent repeat of each unique factor combination.

charging_time

Battery charging time [h]

Usage

battery_charging

Format

A tibble with 32 observations on 6 variables.

Source

Original data set.

# Building a linear model:
battery_lm <- lm(
    formula = charging_time ~ A * B * C, 
    data = battery_charging
)
summary(battery_lm)
