How to activate the lithium-ion battery of "starving to death"?

Many people have a bad habit, often do not pay the electric car battery on the home, the air switch does not turn off, put a few months without riding. When I came to ride a few months, I found that the car was out of electricity and charging. The charger is inserted, but it has always been a green light, even if it is in a 24-hour plug, it is also a green light, because the battery voltage is too low, the charger is too large to the charger output voltage, the charger is unable to heat the electric wire.

This situation is that the battery that is usually said is "starved". The voltage of this battery block battery is generally around 5.6V, which will not exceed 6V.

About such a battery, most is a battery changing battery. But change a set of batteries, it is a bit regret, especially the battery that has just been warranty. Here, the five more good ways are parsed, and most of the "starving" battery can save.

Not paying attention to most of it is not 100%. First, series method. A 12 volt battery of a normal voltage is connected in series on the entire group of batteries.

For example, the original car is a battery of 48V-20AH, then we will join a 12V-20AH battery in series. A full 12V battery voltage is about 13V, which can improve the voltage of the entire set of batteries after series, and then charge it with his original charger, which can be charged, after plugging in the charger, charger, charger Is a red light, at this time, you can enter the electricity. When the charger is turned to the green light, take the other series of batteries.

Then charge it properly. Second, Parallel Law. This method is slightly troublesome.

For example, the vehicle originally a battery of 48V-20AH, and we will join a group, 48V-20AH battery. Everyone understands that the voltage across the parallel circuit is equal, high voltage ends flow into low voltage ends. This approach is also the way many of the battery dealers in tested the complete battery.

Then charging can also achieve the purpose of charging. This principle keeps, in series, the principle is almost. Also upgraded the voltage of the whole group.

Third, low voltage charging method. Charging the small model of the charger. For example, it is a group of 60V-20AH batteries, then we charge with 48V-20AH chargers.

In this case, it can be charged. The principle is also similar to the first, and the voltage of the charging voltage and the battery is closer. Fourth, single battery charging method.

Charging a single battery with a 12 volt motorcycle charger, can activate the battery, but this charging is slow, it is generally charged for more than 7 hours, the battery voltage will rise slowly to 12V. If all the individual charges take time. V.

Special charger method. Tianneng charger is automatically identified by battery voltage, no matter how many volts of a set of battery voltages, you can automatically identify the voltage, he can charge it in. For example, the original car is a battery of 60V-20AH.

This is only 30V, which can be charged inside. As the voltage increases, it is also suitable for a higher level of voltage, and then charging the battery. Taiwan Bell, Green Jia Electric Motor, Jin Peng tricycle is equipped with this brand of charger.

In addition, how to activate the lithium-ion battery "starving"? Laptop battery or mobile phone battery battery activation is called "power ruler calibration" on the Lenovo power management software. When the PC is used to test the power, there is a "design capacity", which is tight with "complete charging capacity". If the two values ​​are the same, the "battery loss" item will be 0%; Generally, the "complete charging capacity" that has just been stored or long-term place is not in time is less than "design capacity".

At this time, it will see that the battery loss is 1%. It means that the battery is not "completely filled", we have to "completely charge and discharge" (completely charged 12 hours after full discharge, 12 hours to or above) is completely "developing" battery "potential". This complete charge and discharge process is called "activation battery", Lenovo ThinkPad and other power management software have a "power ruler calibration" function similar.

Personally think that some old technology batteries such as NIMH to activate. The lithium ion battery theory is to be activated because the protective layer of the SEI is formed on the negative electrode. But this process is actually already completed during the processing detection phase.

Personally, consumers have such services to the battery's misunderstanding. Your mobile phone battery is "hungry" dead, can't open the machine, do not advance, then active! First, the so-called starving is the phenomenon that the battery cannot be charged when the battery has no power or low power. Then there are two ways currently in the so-called activation: First, use universal charge for 20 minutes, you can activate it.

Second, there is a relatively professional voltage slightly higher than the 12 volt power supply to activate the mobile phone repair shop. Dething is to put the power supply positive and negative pole for dozens of seconds or even a few minutes to power it! Finally, after activation, you can charge it with the same direct charge, will not understand the life of life. Charge with instruments.

(If the above method is not, the battery is not faulty, it is necessary to activate the 'regulated power source', the black line connecting the battery negative electrode, the red connecting battery is 3.8V, that is, the charging voltage can be used, that is, the device of the lithium ion battery, It is not necessary to use it for the first time without charging for 12 hours.
