What is the impact of charging and discharging lithium-ion battery packs without protective plates

If there is no protective plate for lithium-ion battery packs, the life of lithium-ion batteries will not only be affected, but the serious point will also present a dangerous environment. A lighter environment will damage the battery and affect its service life. In severe cases, it will cause the battery to swell. In severe cases, it will cause leakage, stress, explosion or fire. The lithium-ion battery pack protection board is to protect the charging and discharging of series-connected lithium-ion battery packs. When fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (generally ±20mV), realize the equal charge of the individual cells of the battery pack, and effectively improve the charging result under the series charging method. At the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single battery in the battery pack, so as to protect and prolong the service life of the battery. Under-voltage protection makes every single cell battery protect against battery damage due to over-discharge during discharge. How to activate the protective plate of the lithium-ion battery pack? At this moment, not all lithium-ion battery pack protection boards have to be activated, but some protection ICs need to be activated, and this is the old IC essentials, the old IC essentials. This is why this is done to make the protection board not work. Reduce the electrostatic discharge energy so that the lithium-ion battery can be stored longer. This is the reason why the address is designed to be activated by charging. If the protection board is activated due to current limiting and may be activated after the load is completely disconnected, it will be difficult for the contest, but you can also short-circuit B- (battery negative) and P- (discharge negative). , Care will be released, remember not to carry a large load when short-circuiting, otherwise it will cause a lot of sparks. The basic reason is that after care, a large voltage difference will be formed at both ends of the discharge MOS, and short-circuiting will discharge The DS level of MOS is directly reset to 0V, and now the protection is released.
