Lithium-ion battery protective plate Introduction Lithium ion battery protective plate is a charge and discharge protection of a series lithium ion battery pack; the voltage difference between each unit cell can be guaranteed to be less than the set value (general 20mV), and realize battery packs. Each of the unit cells, effectively improved the charging effect of the series charge mode; while detecting overpressure, undervoltage, overcurrent, short-circuit, overall temperature, protection, and extension of battery in the battery pack. Life; undervoltage protection makes each single battery while preventing battery due to over-discharging.

The finished lithium ion battery composition has two major parts, lithium-ion battery cores and protective plates, and lithium-ion battery cores are important consisting of positive electrode plates, diaphragms, negative electrode plates, electrolytes; positive plates, diaphragms, negative electrode plates or laminated, packaging, Infusion electrolyte, after encapsulation, the use of the battery, the use of lithium-ion battery protection plates don't know, the lithium-ion battery protective plate, as the name is to protect the lithium-ion battery, the use of lithium-ion battery protection board is to protect the battery But put, but filling, but flow, there is an output short circuit protection. Lithium-ion battery protective plates The lithium ion battery protective plate has two design methods, which are the same positive electrode plate, the negative electrode plate, the principle and the purpose, but the device does not support the modification of the positive and negative protector by software. Set, so it can only be determined by physical correct connection, and the software used is also different, and the connection method and operation method of the two protective plates are described below.

The connection method of the battery protective plate is generally used by the protective plate. There are three kinds of negative electrode panels, negative electrode plates, and the positive electrode panel, and other methods will not be described in detail, as follows: During the process, the battery protective board is in non-standard There are many connection methods when tested on the battery device, and it is also worth mentioning that the test connection is familiar. The simple process is as follows: 1.

Place the device on a relatively horizontal desktop, and adjust the station's stability, so that the equipment is guaranteed The use of environmental humidity is 30 ~ 50%, and the humidity is too high. The case leakage occurs, an electric shock accident; 3, access the appropriate power supply (AC220V / 0.1A), turn on the total equipment power button, open the respective power module button 4, check Whether the device can be displayed normally and normal test.

Several lithium-ion battery protectors Some lithium ion batteries are the third temperature protection line, and some are battery information check lines (for example, for non-original batteries to prompt alarm). Lithium-ion battery is battery + protector. The 3 line will only appear on the protector, the battery is only 2 lines.

There are 2 kinds of lithium-ion batteries, which is apparent from 3.7V, is non-ferrite aluminum, which can be directly changed. Replacement is simple (pay attention to positive and negative): 1: Remove the packaging of the original battery, then the soldering iron separate the protective board and battery.

2: Similarly, remove your new battery's protector, connect the battery to the old protector. .
