| therefore shortening its lifetime and even causing hazardous situations. This requires the adoption of a proper BMS to maintain the states of each cell of the battery within its safe and reliable operating range. In addition to its primary function of battery protection, a BMS should estimate the battery status to predict the actual amount of energy that can still be delivered to the load. | therefore shortening its lifetime and even causing hazardous situations.
