As batteries can store a huge amount of energy, so sudden discharge or fault can result in catastrophic failures. By handling and maintaining the battery’s functional factors, and protective mechanisms, avert these unsafe operations and prevent dangers such as overcharging, overheating, and short circuits.
Over years batteries have been a very crucial part of our life. Be it a watch,a mobile phone or even a trimmer they are widely used in various devices where supply of DC current is required. As the demand for electric vehicles increases and a wide range of battery packs being used there has been a need of a Battery Management System.
This type of protection for batteries is generally part of the battery management systems. Batteries are electro-chemical products, and hence they are typically sensitive to temperature. In general, heightened temperatures for long times can cause permanent and fatal damage to their cells. This is true for all battery chemistries.
This protection is implemented using a circuit that continuously monitors the battery terminal voltage and battery current draw while it is being discharged, thereby estimating its depth of discharge (DoD) or state of charge (SoC).
Not only is a BMS important in indicating the health of a battery, but it also functions to protect the battery while in operation. Each battery cell and chemistry has voltage, temperature, and current range within which it can safely operate. When a cell drops below or exceeds these ranges, it can be detected and controlled by the BMS.
Some protections are required during the charging process, while others make sense only during the discharge process. Thus, some protections are implemented as part of the charger, while others are implemented as part of the battery management system that oversees the charging and discharging process of the battery.
