eGSE Case Study: TPPL Batteries Bolster American's eGSE Seeking a longer lifespan from its fleet of electric burden carriers, American Airlines found its solution after trialing thin plate pure lead technology. A pioneer in electrification of ground support equipment (GSE), American Airlines started a push for battery-powered ramp vehicles in 1996. Today, the carrier remains committed to converting from internal combustion vehicles to electric vehicles to reduce expenses and lower emissions. American's commitment to going electric now includes experimentation with advanced battery technologies that can cut costs further and All photos courtesy of EnerSys 34 GROUND SUPPORT WORLDWIDE AUGUST 2020 have a greater environmental impact over conventional lead acid batteries. In 2015, American faced chronic battery failures in its electric burden carrier fleet. The vehicles were serving as both personnel carriers in the terminal and maintenance carts on the ramp. The lead acid batteries powering them were failing in less than a year - often in as little as six to nine months. Needing a more robust battery solution, American tested a technology that had proven successful in its baggage carts - thin plate pure lead (TPPL) NexSys PURE batteries from EnerSys. As a result, the carrier ultimately found a battery that could last as long as four to six years.
