How to choose a good quality lithium battery charger?
1. Look at the charging speed of the charger
Common chargers use constant current charging, and the charging speed is mainly related to the current provided by the charger. The greater the charging current, the faster the charging speed. In addition to the charging speed, the charging time depends on the capacity of the lithium battery.
It should be noted that the higher the charging current, the higher the quality requirements for the internal system design of the charger and lithium battery. In general, the higher the charging current, the more heat that may be caused during the charging process, and the greater the damage to the performance of the battery. Inferior chargers and batteries are prone to liquid leakage and other safety performance problems during high-current fast charging.
2. Look at the charging efficiency of the charger
Not all of the energy input to the lithium battery during charging is converted into the energy stored by the battery, and part of it is used for side reactions inside the battery and converted into heat during the charging process, so the charging efficiency is always less than 100%.
When charging, the charging current should be controlled within a certain range. If the charging current is too large or too small, the charging efficiency will be reduced. For high-current fast chargers, it is also necessary to specially design the charging method of the lithium battery charger in order to improve the charging efficiency.
3. Look at the charge termination control of the charger
Low-current chargers generally use time control. The greater the current provided by the charger, the more complicated the charge termination control method, and the higher the cost and price. For users, they should choose according to their actual situation.
If the battery capacity used is not very high, or the charging speed is not particularly important, you can choose an ordinary charger; if it is necessary to choose a faster charger with a higher price, it is best to pay more attention to the performance of the charger and lithium battery Some understanding.
4. Judge the quality of the charger
A good charger adopts positive and negative pulse technology, which can effectively prevent, suppress, and eliminate the vulcanization and polarization of the battery. The capacity of the new battery can be kept stable for a long time; the capacity of the old battery that has been polarized and the capacity has been reduced can be restored, and the service life of the battery can be effectively extended by 2 to 3 times. It has an intelligent timing protection function, automatic temperature compensation function, power grid instantaneous impact protection, super moisture and corrosion resistance, and other functions.
5. Charging cable
The same applies to the charging cable. It is best to use the original or set charging cable. If it is a similar charging cable, it should be marked on it to avoid confusion.
