When higher than the calculated electrical current is drawn from the battery, the condition of over-current arises. An abrupt surge in the system’s power demand, short circuits, and faults in electrical load can contribute to the rise in this condition.
From a performance viewpoint, due to the elevated stress on the electrochemical elements, quick over-current conditions can decay battery life which leads to capacity loss and a drop in whole battery health. Multiple protection mechanisms are deployed in a BMS to reduce the challenges linked with over-current scenarios.
Similarly, during a high-load function, over-current protection strives to keep the current within the protected limit, however, during the same high-load function, under-voltage protection makes sure that the battery does not get discharged.
To safely operate such a battery, the discharge current rate and battery voltage level must be monitored. Undervoltage protection is crucial when using lithium-ion batteries because if the battery is discharged below its rated value, the battery will become damaged and potentially pose a safety hazard.
In addition to undervoltage protection, it is important to ensure that the battery is discharging a safe current value. Combining undervoltage protection and overcurrent protection will ensure safe operation of the 48-V battery. For this design, a 48-V, 20-Ah lithium-ion battery was selected.
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.
