In our days there are a lot of electronic products, and these electronic products are inseparable from the battery, such as mobile phones, electric vehicles, cameras are inseparable from the battery. Today, most industry batteries are lithium batteries. And different categories of lithium battery voltage plea are not the same. And the common lithium battery is 12V lithium battery, 24V lithium battery, 48V lithium battery.
48 volt lithium battery application method
1. How to charge the new battery, in the use of lithium batteries should pay attention to is that the battery is placed for a period of time, then enters the hibernation state, at this time the capacity is lower than the normal value, the use of time is also shortened.
But lithium battery is very simple activation, only after 3-5 normal charge and discharge cycles can activate the battery, restore the normal capacity. Because of the nature of lithium batteries, they have virtually no memory effect. Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process.
On the lithium battery "activation" problem, many say: charging time must exceed 12 hours, repeat three times, in order to activate the battery. This "the first three charges to charge more than 12 hours", notably from nickel batteries (such as nickel cadmium and nickel hydride) continued to say. So this statement, can be said at first is misrepresentation. Lithium battery and nickel battery charging and discharging characteristics have a very big difference, and can be very clear to inform us, I have looked up all the strict formal skills of materials are stressed that over charge and over discharge will cause great harm to lithium batteries, especially liquid lithium ion batteries. Therefore, it is best to charge in accordance with the standard time and standard method of charging, especially do not stop more than 12 hours of super long charging (charger flash full can).
In addition, lithium-ion batteries or chargers will automatically stop charging when the battery is full, and there is no "trickle" charge that lasts for more than 10 hours, as nickel chargers call it. That is to say, suppose your lithium battery after full, put on the charger is also empty charge. And none of us can ensure that the characteristics of the battery charge and discharge maintenance circuit will never change and the quality of the full certainty, so your battery will be in a dangerous marginal hesitation for a long time. This is another reason why we oppose long charge.
In addition, can not ignore another aspect is the same lithium battery is not suitable for too much discharge, too much discharge to the same lithium battery is also very unfavorable.
2. When should the initial charge be in normal use
Often can see this statement, because the number of charge and discharge is limited, so should be the mobile phone battery electricity as far as possible to use up and then charge, in fact, the life of lithium battery has nothing to do with this. The following can be an example of a lithium ion battery charging and discharging cycle test table, on the cycle life of the data listed as follows: cycle life (10%DOD) : "1000 times, cycle life (100%DOD) :" 200 times. DOD is the abbreviation of discharge depth. The rechargeable times are related to the discharge depth, and the cycle life at 10%DOD is much longer than that at 100%DOD. Of course, assume that the relative total capacity of practice charging: 10%*1000= 100,100 %*200=200, the latter is still better to intact charge and discharge, but in front of the netizen that to do some correction: Under normal conditions, you should have stored in accordance with the remaining battery power used up and then charge the rope ruler, but assuming that your battery in your estimate of the second day is impossible to adhere to the day, you should be timely preliminary charging, of course, you assume that you are willing to carry the charger to the office and when another matter.
The ruler, which uses up the battery to recharge, is not meant to take you to extremes. As popular as long charging is the saying "try to drain your battery". The practice was actually done on nickel batteries to prevent the memory effect from taking hold, and unfortunately it has also spread to lithium-ion batteries. In the past, there was an example of an automatic shutdown that was still used without charging after the mobile phone battery was reported to be too low. Results in this example, the mobile phone in the later charging and boot were not responsive, had to be sent to the customer service overhaul. This is because the battery due to excessive discharge caused by the voltage is too low, so that it does not have the normal charging and boot conditions.
Personal initiative mobile phone lithium ion battery do not charge too full also do not use no electricity, battery did not run out of electricity on the charge, will not cause harm to the battery, charging to 2-3 hours is appropriate, not necessarily full. But should be every 3-4 months or so, the lithium battery to stop 1-2 times full of good electricity (normal charging time) and discharge.
Lithium-ion batteries that are not used for a long time should be stored in a cool and drab center, with a semi-electric condition (70-80% of the full power, assuming that your mobile phone is fully charged when it flashes 4 grids, then 3 grids), it is best that the full power storage is dangerous and the battery will be damaged, no power storage battery will be destroyed. Check to see if you need a refill every 3-6 months.
Lithium ion battery according to the electrolyte can be divided into liquid lithium ion battery and polymer lithium ion battery, polymer lithium ion battery electrolyte is colloidal, will not be active, so there is no leakage problem, more safe.
