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.
