What are the characteristics of a good-quality lithium-ion battery charger?

1. Look at the charging speed of the charger. Common chargers use constant current charging. The charging speed is important and related to the current supplied 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-ion 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-ion battery. In general, the greater the charging current, the more heat that may be caused during the charging process, and the greater the damage to the battery's performance. 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 the energy input to the lithium-ion battery during charging is converted into the energy stored by the battery, and part of it is used for the side reactions inside the battery and converted into the heat during the charging process, so the charging efficiency It 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. Regarding the high-current fast charger, the charging method of the lithium-ion battery charger must be specially designed to improve the charging efficiency. 3. Look at the charging termination of the charger. The charger with low current control generally adopts the time control method. The greater the current supplied by the charger, the more complicated the charge termination control method, and the higher the cost and price. Regarding 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 have more performance on the charger and lithium-ion battery Get some understanding. 4. To judge the quality of the charger, the electric vehicle charger adopts positive and negative pulse technology, which can effectively prevent, inhibit 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 the functions of intelligent on-time protection, automatic temperature compensation, instantaneous impact protection of the power grid, super moisture and corrosion resistance, and so on. 5. Charging cable The charging cable is the same. 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.
