What is overvoltage protection in battery management systems?
Understanding Overvoltage Protection in Battery Management Systems Overvoltage protection is a safety mechanism that prevents a battery from being charged beyond its maximum voltage rating. This is crucial because excessive voltage can lead to overheating, reduced battery life, or even catastrophic failure such as thermal runaway.
What causes a battery to overvoltage?
Major challenges to both the battery and the system it powers can be the result of deviations from this range, either too high (overvoltage) or too low (undervoltage). During charging or the system’s break down, the condition of overvoltage arises in which the battery accepts more energy than its capacity.
