Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1. Only over-charge and over-discharge protection can be realized.
Positive and Negative Terminals: The positive terminal of the first battery cell is connected to the negative terminal of the second cell, and so on, until the positive terminal of the fourth cell is connected to the negative terminal of the battery pack. Balance Wires: The BMS also requires connection to the balance wires of each battery cell.
A protection device must be sized properly so that the energy flowing from the batteries during the failure will not cause damage to the batteries or other components along the short circuit path. The protection must clear the fault in less than 100 milliseconds. The impedance of the line is mainly resistance and inductance.
The selected protection device must trip in case of a fault in less than 100 ms. In case the fault current provided by the battery does not allow for the finding of protection devices, such as a Circuit Breaker or fuse, that meets the derating criteria stated in point B, it is hence possible to increase the multiplier up to 0.7.
Hardware-type protection board: Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1.
The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
