Technical and economic assessments of electrochemical energy storage systems: Volume 8, Reliability assessment of battery systems: Final report, September 1978-May 1985

Typical performance indices used for conventional generating units are modified so that only unavailability due to equipment failures, and not due to battery charging, is considered. It is concluded that battery system reliability is high and should not be a major consideration in the choice of converter configuration, and that battery system cost could be reduced by reducing component redundancy in the balance of plant.
