Low voltage does not mean low hazard! Even contact with extra low voltage below the limit value of 50 V AC or 120 V DC can cause accidents. In some critical work areas, it may be necessary to limit the voltage to lower than 24 V AC or 60 V DC, for example, in conductive or wet locations with restricted movement.
Fault mechanism study on Li-ion battery at over-discharge and its diagnosis approach
ICA curves could be obtained through a low-rate current charge/discharge which offers close-to-equilibrium condition to reduce the polarisation impact. A fixed voltage sample interval – 1 mV was selected in our work and further smoothing and noise suppression were achieved through a 5-point moving average, which was realised …
