Details

Description: The BVSA is designed to give an early warning for cells, in a battery system, that are performing different from the other cells. The battery system being monitored must consist of two equal blocks coupled in series with an accessible centerpoint. Operation: The measuring system is based on a comparison of the voltage from the two blocks. Over the lifetime they are charged and discharged equally and the voltage will, within close limits, be the same as long as all cells in both blocks are healthy. At the end of the lifetime, or if a cell is shorted, the two blocks will perform different. The BVSA will sense the difference in performance and the internal relay will give an early warning by dropping out. Information about which battery block that is defect is indicated by the LEDs on the front. In order to prevent false alarm the BVSA includes a timing function. Application: Detection of an early failure in battery cells within a battery system. For a complete monitoring system the BVSA can be used together with a standard battery voltage monitoring relay - type BMCD (HI/LOW)
