Objectives and problems to be solved: The objective of the " ABLE " project is to develop a new advanced small and compact 12V <=100Ah VRLA (Valve Regulated Lead Acid Battery) especially designed for renewable energy applications like small and medium size PV systems. The final target is to reach higher cost effectiveness of PV systems and very significant exploitation cost reduction of such installations. The main R&D orientation is to promote very high battery reliability (without maintenance) leading to life time more than 15 years (5000 cycles @50% discharge) and to reach a higher energy efficiency for improvement of service to end user during low irradiation periods. Description of work: The Innovation in the project is based on innovative battery design using new collectors and new electrolytes and active materials formulations. The direct integration of sensors and electronic components in the battery will be performed in order to allow a better management of batteries, anti fraudulent utilisation and high adaptability to various PV systems. The concept is a "plug and play" battery with modular parallel association depending on the capacity of the PV system using tele diagnostic or teleprocessing. The " ABLE " project milestones are to reach the targeted technical battery performances (reliability and lifetime) on a complete PV systems of different types and size; to solve problems related to integration of an electronic device in the battery and to succeed in reaching low manufacturing cost objectives. The partnership of this project joins the forces of: - a battery manufacturer, - an electronic and PV systems manufacturer, to design and prototype the electronic device and to fit out its systems with the batteries, - a laboratory with skills in electrochemistry for power sources, - a public organisation and an energy research foundation to test prototype batteries at laboratory scale and PV systems using new batteries. Expected results and exploitation plans: This product should present near the same investment cost than conventional batteries using tubular technology (150 EUR/kWh) but will provide very significant exploitation cost reduction of PV installations (more than factor 2). The results will lead to assess the difference between real and expected performances and the possibilities of improving the technique. Finally chances of success of industrialisation (costs, performance, manufacturing process) will be evaluated.
