Low Cost. Life Changing. Lead Carbon.
There are several words you can associate with the technology behind our LC demonstration programs, but the most important aspect of this system is its potential to revolutionize the automotive and energy storage industries at minimal cost to the producer. The concept of combining carbon-enhanced lead-acid – or “lead carbon” – batteries with other bolt-on performance-enhancing features, such as electric superchargers and integrated starter generators, can actually help to provide a more efficient and cost-effective, yet still “fun to drive,” automotive system. In addition, the LC battery technology is being developed to power the next generation of energy storage applications, including load-leveling and smart grid support.
What makes Lead Carbon batteries different from conventional lead-acid batteries?
Quite simply, lead carbon batteries provide better performance in partial state-of-charge operations, making them optimal for applications requiring high-rate charging and recharging.
In hybrid electric vehicle operation, the battery has to remain at partial state-of-charge in order to receive and deliver frequent pulses of discharge and recharge current. Experience has shown that conventional lead-acid batteries quickly lose capacity under such conditions because of sulfation in the negative plates.
ALABC research has shown that the addition of certain types and amounts of carbon to the negative plate can inhibit this sulfation and thus allow these Lead Carbon batteries to function well in this application.
The LC SuperHybrid Concept: Optimizing Engine Technology to Deliver ‘More from Less’
In 2011, ALABC showcased this technology through a unique demonstration concept called the LC SuperHybrid. Based on a 1.4 liter Volkswagen Passat, the LC SuperHybrid combines next-generation lead carbon batteries with an electric super charger and a belt-driven integrated starter generator to enhance performance, extend mileage and lower emissions at an affordable cost. The demonstration was conceptualized in partnership with automotive component supplier Controlled Power Technologies, powered by Exide Orbital lead-carbon batteries, and designed and developed by automotive system producer AVL Schrick, with the help of other Tier 1 OEM suppliers, such as Valeo, Provector, and Mubea.
Designed in both 12V and 48V architectures, the LC SuperHybrid keeps CO2 emissions low while generating a very high torque, demonstrating that downsizing a conventional engine in this manner can have a significant environmental impact without minimizing the driving experience.
This concept has been further realized in partnerships with other OEMs like Hyundai/Kia and Ford Motor Company to develop other demonstrations like the Optima T-Hybrid and the ADEPT, which have been on display at several high-profile automotive industry events and exhibitions.
