Active cell balancing calibration: BayerRecent Research Landscape

Voltage imbalances between series-connected cells lead to premature pack degradation and reduced usable capacity. These innovations employ active charge redistribution to equalize state-of-charge and extend battery cycle life.

What technical problems is Bayer addressing in Active cell balancing calibration?

Undetected thermal management failure

(34)evidences

Inadequate monitoring of temperature and cooling system functionality leads to catastrophic cell failure. Early detection of thermal anomalies prevents hazardous energy release and battery degradation.

Inaccurate charge capacity estimation

(20)evidences

Voltage measurement errors and sensor drift lead to incorrect battery charge assessments. Reliable estimation prevents premature cell degradation and unexpected vehicle immobilization.

Undetected electrical insulation failure

(12)evidences

Undetected residual voltage and measurement errors in high-voltage systems pose safety risks and prevent accurate state-of-charge determination. Precise verification of voltage absence or presence ensures operational safety and prevents cell degradation during testing.

Inaccurate internal state estimation

(5)evidences

Uncertainty in real-time impedance and parameter values leads to inefficient charging and potential cell damage. Precise estimation prevents overstressing the battery and optimizes energy throughput.
