Are Ultracapacitors the Next Big Trend in Backup Generator Starting?

摘要

Among generator starting professionals, it is widely accepted that the most prevalent reason for generator set (genset) failure-to-start is issues with the lead-acid battery starting system. Service providers have said that approximately 80 percent of genset failures-to-start can be attributed to battery system failure resulting from poorly maintained batteries, charger failure, or cable and terminal corrosion. After several decades of these challenges, the genset industry is embarking on a new trend toward ultracapacitor-based starting systems, which offer advantages over traditionally used lead-acid battery-based starting systems.
