How to Choose the Right Lithium Battery Charger

The quality of the lithium battery charger directly determines the service life of the lithium battery, so it is very important to choose a high-quality charger. The output voltage of the charger must match your battery and must be accurate.


Ⅰ. Charging speed of lithium battery charger


Ordinary 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 also depends on the capacity of the lithium battery.


It should be noted that the higher the charging current, the higher the quality requirements of the internal system design of the charger and lithium battery. Generally, the larger the charging current, the more heat may be generated during the charging process, and the greater the damage to the battery performance. Inferior chargers and batteries are prone to liquid leakage and other safety performance issues during high-current fast charging.


Ⅱ. Charging efficiency of lithium battery charger


Not all the energy input to the lithium battery during the charging process is converted into the energy stored in the battery, and part of the energy is used for side reactions inside the battery and converted to 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 decrease. For high power battery charger, it is also necessary to specifically design the charging method of the lithium battery charger to improve the charging efficiency.


Ⅲ. Check the charge termination control of the lithium battery charger


Low-current chargers usually 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, the choice should be based on the actual situation. There are many types of the battery, such as 36v 2a lithium battery charger and 15v 3a charger and so on. 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 use a charger and a lithium battery to understand the performance More information.


Ⅳ. Judge the quality of lithium battery charger


A good electric vehicle 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 reduced in capacity can be restored, and the service life of the battery can be effectively extended by 2 to 3 times. It has intelligent timing protection function, automatic temperature compensation function, power grid instantaneous impact protection, super moisture-proof and corrosion-resistant functions.


Ⅴ. Charging cable for lithium battery charger


The same is true for charging cables. It is best to use the original or already set charging cable. If it is a similar charging cable, it should be marked to avoid confusion.
