Lithium-ion Challenges for Lead Acid Replacement
Cost
– Mitigated lifetime use, as long as lead acid is utilized for deep
discharges
Electronics
– Battery must contain power electronics capable of high
discharges while managing for external shorts
– Safety for overcharge, overdischarge and over/under voltage
– Charge management/regulation to ensure proper system
function
