Battery Torture Chamber Electric car batteries will be critical in the renewable age. Car batteries fail for many reasons. This overview of electric car batteries and their problems will illuminate critical problems faced by electric car designers. Students can use the models built in Scratch and Java code (www.processing.org) to explore a simplifed lead acid and lithium ion battery under stress. This battery torture chamber will allow students to heat, shake, break, and destroy batteries using different methods. Students will better understand the basics of battery design by breaking them in this virtual cartoon world. Will electric car batteries survive repeated cycling proposed to balance power grids?
