To reach future objectives on energy consumption and emissions attention recently shifted towards hybrid electric vehicles (HEV). Specific power needs for HEVs are more demanding than battery electric vehicles: a power-to-energy-ratio of 20-30 instead of 1 for BEVs. No low cost batteries are now available meeting this demands. Also there is a strong need for more electric power in vehicles: shifting from 12V to 36V, best served with a high specific power battery. Hence the main objective of this project is to develop a compact bi-polar lead acid battery for HEVs and Starter-Alternator applications, with a specific power of 600W/kg.
Further objectives are a weight reduction of 75% compared to conventional lead acid, a maximum (dis) charging time of 30 seconds during peak power, a life time of 5 years, an operation temperature of -15 to +40 degrees Celsius and a maximum price of 1500 Euro.
