How do you activate lithium-ion battery after a long time?

Not all the lithium battery protective plate needs to be activated, just some protection IC need to activate. The old IC solutions need to do so is to prevent the board working so as to reduce the battery self-discharging capacity. Therefore, the battery can store for longer time. This is why the design needs recharge activation.

The field effect transistor of lithium-ion battery is used as protection components. In order to ensure the battery is not re-engage when abnormal circuit and to special circuit design. The method is to protect the circuit control part of the power supply is in protecting use effect of tube at the back of the power supply, only after the normal conduction protecting tube circuit will work. So after the first use or have to protect, for subsequent circuit power disconnected, no power supply circuit, protect circuit is unable to work. The battery there would be no output. At this time, only will be connected to the battery charger, use the charger for protection circuit of power supply control circuit part, control part to work, the battery can be normal use.

If protection plate due to the current limiting protection, charging may need to activate or completely disconnect the load after activation, it would be relatively more troublesome, but can also be B - (battery) and P - (discharge) a touch nipple, protection would release, remember when a touch nipple remember don't bring big load (such as transfer has been screwed), otherwise it will spark may take great yo, the fundamental reason is to protect the discharge form a larger pressure difference on both ends of the MOS, after a touch nipple discharge is the MOS of the level directly reset to 0 v, D - S protection release at the moment.

Note: should be the most boards are common, even if some no, so touch don't cause the board damaged.

It is well known that the lithium battery is present in the new energy battery is used in various fields, but the protection of the lithium battery needs protection board a lot of people don't know, in the battery protection board plays a vital role, let's learn about the protective plate structure and the protection principle.

Protection board, there are two core components: a protection IC, and it is precisely the comparator to obtain reliable protection parameters. The other is a MOSFET series ACTS as a high-speed switch in the main discharge circuit, the protection action, IC by monitoring the battery voltage difference to control the MOS tube. Common protection board and resistor, capacitor, and auxiliary FUSE, PTC, NTC, ID, storage, etc. Protection board B +, B - answer the batteries the positive and negative, respectively. P +, P - is to protect the board output of the positive and negative, respectively. As shown in figure is a kind of protection board schematic diagram:

Why does some lithium-ion battery protective plate need to activate? How do you activate lithium battery protective plate?

Protection board will be on the battery overcharge protection, discharge protection, short circuit protection, over current protection and temperature protection.

Lithium-ion batteries in charging for constant current, constant voltage, at the beginning of the charge, for the constant current charge, as the charging process, voltage rises to a certain value, to a constant voltage charging, until the current more and more small. Battery charge in the process, if the charging circuit out of control, can make the voltage exceeds a certain value after continue to constant current charging, the battery voltage will continue to rise, will lead to cell damage or security problems. When battery protection board, protect board will start the overcharge protection function, and to cut off the MOS tube, recharging the battery pack is forbidden, to ensure the safety of the battery.

Other forms of protection by the same token, can monitor the battery protection board of happening, and take protective measures.

Lithium battery protection board is in tandem Lithium battery pack the charge and discharge protection; Between charged can ensure each monomer battery 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, under voltage, 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.

Put the power plug in, a day or so of time (not boot), see if I can activate themselves

For a long time how to activate the lithium battery

2.Take out the battery, battery has a button on the back and a few LED lights, three seconds or long press button (try), see if I can activate

For a long time how to activate the lithium battery

3.Are generally low voltage protection, protection board garbage universal charger to serve...If not using a mobile power supply leads are negative to the battery is the cathode by a few times can also be activated, good control of time not too long can also activate...After activating voltage can normal charging.

4.If you know the circuit, to find the external power charging, can look for a voltage between 11 V ~ 12.6 V power supply, current under 1000 ma. Is negative as shown in figure.

5.Lithium electricity place need to use the correct way to store for a long time.1, when placed over a long period of time, need to charge 2, every 3 to 6 months in charge, to continue to place 3, to be placed in a cool and dry environment, should not be in the damp heat environment.
