Introduction to battery pack terminology

It means that when the battery is charging and the cell voltage reaches the IC preset parameters, the IC starts the protection function and controls the MOS to turn off the charger's power supply, so that the cell stops charging. Over-discharge protection means that when the battery is discharging, when the battery cell voltage reaches the IC preset parameters, the IC starts the protection function, controls the MOS to turn off, and stops the battery cell from discharging. Over-current protection Over-current refers to the fact that when the battery is discharged, the current is very large, or an abnormality causes a large current, the IC chip will start the over-current protection, control the MOS to turn off, so that the battery cell stops discharging. Short-circuit protection The short-circuit protection principle is the same as the ground current, the overcurrent is very large or even the short circuit state. The typical characteristic of thermistor is that it is sensitive to temperature and exhibits different resistance values u200bu200bat different temperatures. The resistance value of a positive temperature coefficient thermistor (PTC) is higher when the temperature is higher, and the resistance value of a negative temperature coefficient thermistor (NTC) is lower when the temperature is higher. The working current refers to the power consumption current of the client's host under normal conditions. (This current should not exceed the normal discharge current of the battery). The maximum working discharge current refers to the power consumption current of the client's host when it is turned on to the maximum. Peak or instantaneous discharge current refers to the highest point (or instantaneous or lasting several seconds) power consumption of the client's host caused by some unspecified factors, but this current value may be greater than the maximum operating current, or it can be less than the maximum operating current. If it is less than, it can be ignored. If it is greater than, then pay attention. The discharge capacity of a nominal capacity battery at 0.2C discharge, in mAh. The average voltage of the battery during the whole process of discharge at a nominal voltage of 0.2C, in mV. The internal resistance refers to the resistance that the current flows through the battery when the battery is working, and the unit is m.
