Example 12.4
Design the battery for an industrial application that requires 10 kWh energy in 1.5 h
for a dc load at 120 V three times daily for 250 days every year. The battery must be
completely recharged in 2.0 hours after each discharge. Use Li-ion cells in this exam-
ple, but the design process will be applicable to other electrochemistries as well. Use
the following Li-ion cell parameters: average discharge voltage 3.6 V, average charge
voltage 4.2 V, c/d ratio 1.1, trickle charge rate C/100, and average life 2000 cycles at
100% DoD. For reliability purposes, design the battery with two strings in par ...
