Abstract: A system for actively controlling the charging profile of a battery uses a software-based alternator control unit to control the charging voltage. The system optimizes battery and alternator life. The system, on a dynamic basis, uses battery open-circuit voltage (OCV) to estimate battery state-of-charge (SOC). Also, the charging current of the battery is periodically estimated; this, after processing, provides an estimated SOC of the battery.
Abstract: A system for actively controlling the charging profile of a battery uses a software-based alternator control unit to control the charging voltage. The voltage applied to the battery is initially increased over normal values following battery discharge, to charge the battery back as fast as possible without damaging the battery or alternator. The voltage is then reduced to a normal charging level, and subsequently further reduced to a float level.
Abstract: Improved lead acid storage cell grid for a storage battery which includes a tab extending upwardly and at right angles from a slotted cell grid. A plurality of like polarity positive or negative interleaved battery grids in a cell are joined into combined tab buses which are then joined to adjacent battery cells to form an internal series connection of the battery cells, thus eliminating the requirement for a top bar current collector and intercell connector.
