Product overview
The BEU8635-24 balances and monitors lithium-ion cells in one series-connected 24-cell battery. Bilateral DC-DC converters connect the cells to a common share bus, redistributing charge so each cell approaches the average of the others. Cell-voltage and total-battery-voltage monitoring support telemetry and status reporting. Discrete outputs indicate critical voltage conditions so the surrounding system can stop charging or shed loads. MIL-STD-1553B telemetry supports data logging and monitoring.
