Aging of lithium-ion batteries

BMS; Battery Monitoring System

The BMS, or battery management system, is an electronic device designed to manage and monitor the critical parameters of each cell in a rechargeable battery (voltage, current, temperature and state of charge), in order to guarantee performance and safety.

SOH; State Of Health

The SOH, or state of health, of a battery is a measure that reflects its overall condition and ability to store and deliver energy, or power, compared with its new condition.

SEI; Solid Electrolyte Interphase

The SEI, or solid electrolyte interphase, is a thin layer of solid material that forms spontaneously on the surface of the negative electrode of lithium-ion batteries during the first charging cycles, and plays a crucial role in their operation and long-term...
