Electric Insulation Coordination to Prevent Electric Arcs in Lithium-ion Batteries

Abstract:
Battery systems, particularly those for electric vehicles, uses a simple electrical architecture with few components. The battery management system (BMS) is often considered as the key component for safety. Literature and our own experience tend to prove that multiple insulation defects for example due to coolant leakage is often the initial cause of batteries fires. Batteries, such as lithium-ion technology ones, for example, have specific risks. It is necessary to design electric architecture and electric insulation coordination in accordance.
