What is a lithium battery charger?
We should pay attention to what aspects when in use?
Lithium battery charger is specially used for lithium ion battery charger.
Lithium ion battery of charger demand is higher, need protection circuit, so the lithium battery charger usually have higher precision of control, can carry on the constant current constant voltage to the lithium ion battery charging.
Lithium battery charger function characteristics of single section or 8.
Section 4 v double ideal lithium ion or lithium polymer battery charger control circuit;
Above 1 [
The precision of voltage;
The charging process, the user can change the charging current in advance;
Constant current charging, the charging current is adjustable;
Constant voltage charging process;
Automatic recharging process;
The temperature control in the process of charging.
LED charging status indication;
Battery is not normal detection;
Low power supply voltage, low power consumption of the sleep mode, the battery leakage current minimum;
Few peripheral components;
If your lithium battery, after full on the charger is Bai Chong.
But none of us there is no guarantee that the battery charge and discharge protection circuit will never change and quality according to the features of foolproof.
So your battery will be on the brink of danger for a long time.
This is another reason we object to a longer charge.
About lithium ion battery charge and discharge cycle experiment table, the cycle life of the data are listed as follows: cycle life,
A 1000 - cycle life,
200 times the DOD is the abbreviation of the depth of discharge.
From the table, but the depth of the number of charging and discharging, 10% DOD cycle life than 100% DOD much longer.
, of course, if the conversion to the actual charge relative to the total capacity: * 1000 * 200 = 200 = 100100%, 10% of the latter to fully charge and discharge is still relatively better.
But mainly embodied in the life of a lithium battery charge and discharge cycles, this cycle is an absolute concept, last time using 30% power, full of electricity, next time again USES 70% of its electricity, and full of electricity, this is just a charging cycle.
So follow the slogan of lithium battery inventor & other;
Use namely filling, namely, filling the box & throughout;
Methods use lithium battery.
Supernormal charging time and completely empty battery may result in excessive charging and discharging, to permanent damage across the electrodes of lithium ion battery, from molecular level, discharge will cause excessive release of lithium ion cathode carbon makes its layer structure appeared to collapse, excessive charging will take too much lithium ion shoehorned into the structure of cathode carbon, and makes some of the lithium ion can no longer be released.
This is also why often equipped with lithium ion battery charge and discharge control circuit.
Lithium ion batteries are generally management with a chip and charge control chip.
Which management chips have a series of register, capacity, temperature, ID, such as charging status, discharge times value.
These values in use will change gradually.
Use the & in the other
Use a month or so should all put a filling & throughout;
The main role should be fix improper in the register values, make battery charging control and nominal capacity consistent with actual situation of the battery.
Electricity statistical chips by recording discharge curve (
Voltage, current, time)
Can sample to calculate the capacity of the battery.
And lithium ion battery after repeated use, discharge curve is will change, if the chip has no chance to read the complete a discharge curve, the calculation of power that is not accurate.
So we need to deep filling to calibrate the battery chip.
Daily use the matters needing attention in the first three time charge completely unnecessary for exceptional time charging such as 12 hours to activate the battery, charging circuit had protection, with no use.
Often use should be avoided in the process of completely discharge (
Use the power to the black screen)
Placed for a long time not to use, or frequent or use after a period of time, is a full charge and discharge, the battery can use namely after filling, only after long time use need to do full charge and full discharge again again again.
If you want a battery need not, between the long suggest 40% charge to be placed, in order to protect the batteries.
Finally, mainly reflected in the life of a lithium battery charge and discharge cycles, this cycle is an absolute concept, last time using 30% power, full of electricity, next time again USES 70% of its electricity, and full of electricity, this is just a charging cycle.
Knowing more than lithium battery charger, are you some idea of lithium battery.
And need to find, lithium battery charger and so on electronic, our company is specialized is engaged in the lithium battery charger and electric car chargers, etc.
