Is it possible to protect the lithium-ion battery pack?

Regarding the idea that some people will present the lithium-ion battery pack without protecting the board, the big reason is the presentation of the lithium iron phosphate battery. Because of the news that the lithium iron phosphate battery pack is not afraid of overcharging or over-discharging, the argument that lithium-ion batteries can be used without a protective plate has emerged. However, up to now, there have been no battery manufacturers that really claim not to use protective plates. Li-ion battery pack protection board is to protect the charging and discharging of series-connected lithium-ion battery packs. When the battery is fully charged, it can ensure that the voltage difference between the individual cells is less than the set value, realize the equal charge of the individual cells of the battery pack, and effectively improve the charging result under the series charging method. When the lithium-ion battery is completely immune to overcharge, over-discharge, etc., when the lithium-ion battery can completely replace the protective plate in the design of the lithium-ion battery itself, the lithium-ion battery can or does not need the protective plate, but at this stage, Lithium-ion battery packs should be protected as usual. Although, the protection board will damage the battery if the protection board is not well designed. Therefore, when purchasing lithium-ion battery packs, it is most inconvenient to purchase lithium-ion batteries produced by regular manufacturers. In this case, the quality of lithium-ion batteries is more guaranteed. If the lithium-ion battery pack does not need to protect the board, for some electric vehicle users who do not pay attention to the daily care of the battery, the service life of the battery will be greatly reduced, and more obstacles will also appear, leading to some dangerous environments. In the process of using lithium-ion batteries, each time it is overcharged, over-discharged, or short-circuited, the battery life will be eliminated. In severe cases, the battery is directly scrapped! Generally, the overcharge voltage of a single-cell lithium-ion battery cannot be higher than 4.25V, the overdischarge voltage cannot be higher than 2.75V, and the maximum charge and discharge current is 1C (C implies the battery capacity, such as the battery is 1200mAh, 1C charge and discharge The current is 1.2A). If there is no protective plate, directly short-circuit the lithium-ion battery pack and overcharge it will cause the battery to bulge. In severe cases, it will leak, squeeze, explode or catch fire.
