2 / 89 page AS8506 – 2 ams Datasheet, Confidential:2013-Sep [1-00] G e n e ral D e sc rip t ion Key Benefits & Features The benefits and features of AS8506, Battery Cell Monitor and Balancer IC are listed below: Figure 1: Added Value of using AS8506 Applications The applications of AS8506 include: • The AS8506 is ideal for simultaneous cell monitoring and cell balancing in stacked energy storage systems. Current levels in the 100 mA range enables to compensate accumulative SOC mismatch over the entire cell pack. • Typical applications are - Li-Ion batteries up to 200 cells for electric vehicles, - Energy storage systems to buffer energy from PV panels or for emergency power supplies, - Battery management for e-scooters and e-bikes, - Li-Ion or ultra capacitor based board net battery management systems in the 12V/48V domain, for handheld applications like power tools, laptops and in general all Li-Ion battery powered systems. Benefits Features Reduce filter / synchronization effort. Acquired data have same time stamp to inherently generate accurate comparison results independent from load transients. Simultaneous cell voltage capture for safe operating area (SOA) monitoring and balancing. Strongly reduces data communication and data processing and thereby improves EMC robustness. Autonomous balancing and SOA monitoring. To compensate accumulative charge differences only. This mitigates cases of occasional wrong balance decisions due to flat OCV characteristic or mismatch in cell temperature Autonomous passive balancing in the 100 mA range Intrinsic inter module balancing through charge redistribution, efficiency improvement in case of leakage path due to defect induced leakage in particular cells. Option for active charge balancing with very few external components. For OCV capture, cell impedance calculation, diagnosis Absolute cell voltage read out, read out of two temperature sensors. Small form factor, low BOM 40-pin MLF (6x6) package, very low number of external components. |
