How to activate the lithium-ion battery in starving?

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. After a few months, I will find that the car is dead and charging. Don't go in.

The charger is inserted, but it has always been a green light, even if it is 24 hours to plug it or 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 is the usual battery is "starved". The voltage of this battery block is generally around 5.

6V, which will not exceed 6V. About such a battery, most is a battery. But change a set of batteries It is a little regret, especially the battery that has just been warranty, and the five more ways to rescue most of this "starving" battery.

Notice is that most of them are not 100 Piece. First, series of LEDs. A normal voltage 12 volt battery is connected in series.

For example, the original car is a battery of 48V-20AH, then we will join a 12V-20AH battery. One piece of electricity is fully The 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 in, insert the charger, the charger is a red light. At this time, it can be charged in.

When the charger is turned to the green light, take the other series-connected battery. Then it will be charged. Second, Parallel law.

This method is slightly troublesome. Such as a vehicle It turned out to be 48V-20AH batteries, and we will join a group of 48V-20AH batteries. Everyone understands the voltage across the parallel circuit is equal, high voltage ends flow into low voltage ends.

This approach is also a lot of batteries. The dealer can use the way to test the battery that is completely uncharacted. Then charge the purpose of charging.

This principle keeps a battery, the principle is similar. It is also the same voltage to increase the voltage. Third, low voltage charging method The small model of the charger is charged.

For example, it is a set of 60V-20AH batteries, then we charge with 48V-20AH charger. In this case, it can be charged in it. The principle is also Similar to the first, the voltage of the charging voltage to the battery is closer to the voltage.

Fourth, single battery charging method. A single battery is charged with a 12 volt motorcycle charger, which can activate the battery, but this charging Slow, usually more than 7 hours, battery voltage will rise slowly to 12V. If all single charge take time.

Five, special charger method. Tianneng charger is automatically identified, regardless of battery voltage, no matter How many volts have a set of battery voltages, they can automatically identify the voltage, he can charge it. For example, the original car is 60V-20AH battery, now 30V can not be charged inside.

As the voltage increases, it is fully adapted to a higher order voltage, and then charge the battery. Tai Bell, Green Jia Electric Motor, Jin Peng tricycle is equipped with this brand of charger In addition, how to activate the lithium-ion battery "starve"? 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 supply, there is a "design capacity", which is tightly followed by "complete charging capacity", if two items If the value is the same, it will see the "battery loss" item below to 0%; generally, the battery "complete charging capacity" that has just been stored or long-term place is less than "design capacity", at this time Will see that the battery loss is 1%.

It means that the battery is not "completely filled". We must "completely charge and discharge" (completely disconnected after full discharge 12 hours to or above) benefit 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, some old technology batteries, such as NIMH to be activated.

Lithium ion battery theory is It is intensified because it is to form a layer of SEI in the negative electrode. But this process has actually completed in the processing detection phase. Personally think that consumers have such services to the battery's misunderstanding.

Your mobile phone battery is "hungry" If you can't open the machine, you can't advance it. First, the so-called starry death is a phenomenon that the battery has no longer charges or low power is low. Then there is two ways to activate: First, use universal charge for 20 minutes or so, you can activate it.

2 is to mobile phone The repair shop has a more professional voltage slightly higher than the 12 volt power supply to activate. Dething is to put the power supply positive and negative poles for dozens of seconds or even a few minutes to give it power, and open it! Finally, you can charge it with the same direct charge after activation. If you have a clear impact on your life, you will not be understood with the instrument.

Activated, black line connecting battery negative electrode, red connecting battery positive electrode, charging voltage reaches 3.8V, can be used, using a lithium ion battery, the first use does not charge 12 hours, this is not necessary!.
