I represent the operating current of the battery. • U and the battery operating potential by V represent the open circuit potential. • T represents the operating temperature of the battery. These variables describe the relationship between current, potential, and temperature in the battery''s performance.
The operation of a battery inherently generates heat, and the efficiency of the battery operation is profoundly influenced by its thermal environment. Furthermore, excessive heat can be detrimental, potentially leading to a hazardous state known as thermal runaway, which can result in battery malfunction or even fires.
A BMS helps mitigate this risk by monitoring the temperature of the battery and taking corrective measures if the temperature exceeds its safe operating range. 4.5 The Protection of Short Circuit: To protect the battery from short circuits, the Battery Management System (BMS) continuously monitors the voltage and current level, among …
