Advanced Battery Management for Hybrid Vehicles
Technology Description:
Eaton is developing advanced battery and vehicle systems models that will enable fast, accurate estimation of battery health and remaining life. The batteries used in hybrid vehicles are highly complex and require advanced management systems to maximize their performance. Eaton's battery models will be coupled with hybrid powertrain control and power management systems of the vehicle enabling a broader, more comprehensive vehicle management system for better optimization of battery life and fuel economy. Their design would reduce the sticker price of commercial hybrid vehicles, making them cost-competitive with non-hybrid vehicles.
Potential Impact:
If successful, Eaton's advanced battery management system would reduce system errors and achieve a 50% reduction in battery size without significantly impacting the battery lifetime or hybrid vehicle performance.
Security:
Advances in energy storage management could reduce the cost and increase the adoption of electric vehicles and renewable energy storage technologies, which in turn would reduce our nation's dependence on foreign sources of energy.
Environment:
Improving the reliability and safety of electric vehicles and renewable energy storage facilities would enable more widespread use of these technologies, resulting in a substantial reduction in carbon dioxide emissions.
Economy:
Enabling alternatives to conventional sources of energy could insulate consumers, businesses, and utilities from unexpected price swings.
