The article presents a break down of the battery-management system of the Chevrolet Volt car which drives safety in the multicell lithium-ion battery stack. Two key subsystems are revealed to be used by battery-monitoring boards to check cell health and send digital results to a host processor which orchestrates system operation. Li-ion cells are cited to be packaged in 96 battery-cell groups. The Volt is described to have a safe state of charge window of 58% to 65% depending on driving mode.
