Electrostatic Discharge: What is Electrostatic Discharge?
Electrostatic and magnetic lines of flux exist in every circuit. If board routing encloses large loop areas, the conducting paths will enclose more of the magnetic flux, which, in turn, will induce current in the loop due to the loop acting as an antenna. This loop current will cause interfering fields that will affect components in the circuit.
Incipient short-circuit fault diagnosis of lithium-ion batteries
Battery short-circuit (external or internal) is a major concern as it is usually a precursor to thermal runaway. Hard short-circuit (mΩ magnitude) will almost instantly lead to fire or explosion [11]. But in case of soft short-circuit (100/10/1 Ω) the thermal drift is going to be progressive.
