Several wiring methods of lithium battery protection plate

The lithium battery protective plate is the series lithium battery pack the charge and discharge protection;On a full charge can ensure each monomer battery between the voltage difference is less than the set value (plus or minus 20 mv) commonly, realize each battery monomer battery charge, effectively improve the serial charging mode of charging effect;At the same time detection of every single battery in the battery pack, overvoltage, undervoltage, over current, short circuit, over temperature condition, protect and extend the service life of the battery;Under-voltage protection makes every single battery in discharge to avoid when using battery damaged because of over discharge.

Finished products of lithium battery mainly has two parts, and protection of lithium battery core board, lithium battery core is mainly composed of positive plate, diaphragm, negative plate, electrolyte composition;Positive plate, diaphragm, negative plate coil or cascade, packing and infusion liquid electrolyte, after packaging made from batteries, lithium battery protection board a lot of people don't know, the effect of lithium battery protection board, just as its name implies is to protect lithium batteries, lithium battery protection board's role is to protect the battery but put, but filling, but flow, and the output short circuit protection.

The connecting way of lithium battery protection board

Lithium battery protection board has two kinds of design methods, respectively is the positive plate and negative plate, the principles and purposes are the same, but the device does not support by software to modify the positive and negative protection board Settings, so only through a physical connection to determine right protection way, the software used at the same time is also different, respectively introduce two kinds of protection plate under the connecting method and operation method.

Lithium battery protection board several connection methods is introduced

Battery protection board connection protection plate is usually used with the cathode plate with the mouth, the cathode plate mouth, the anode with three mouth board, other ways differ a tautology, detailed as follows:

1, the negative plate mouth connection mode, the attachment order please refer to the table below.

Lithium battery protection board several connection methods is introduced

2, negative plate connection mode with the mouth, the attachment order please refer to the table below.

Lithium battery protection board several connection methods is introduced

3, are connecting plate with the mouth, the attachment order please refer to the table below.

Lithium battery protection board several connection methods is introduced

Battery protection board in the process of test on non-standard battery equipment from time to tome a lot of connection methods, also to test the connection was familiar, simple process is as follows:

1, place the equipment in the relative levels of the desktop, and smooth degree of adjustment equipment, make it smooth;

2, to ensure that the equipment using the environment humidity in 30-50% range, high humidity prone to casing leakage, electric shock accidents.

3, access to the appropriate power supply (AC220V / 0.1 A), open the total equipment power button, the button open their power supply module

4, check whether the device is able to normal display and normal test.

Lithium battery protection board several connection methods

There are someLithium ion batteriesThird line is the temperature protection, some are battery information check line (such as changed the original battery to prompt alarm).Lithium ion batteries are + battery protection board.3 lines will only appear on the protection board, the battery will never only two wires.There are two kinds of lithium ion battery, obvious 3.7 V is iron and aluminum phosphate, can be in directly.

Replacement is very simple is cathode) (note:

1: the battery packaging tear down, and then soldering iron to separate and battery protection board.

2: the same then pulled down your new battery protection board, the battery from the protection of the old board.
