The quality of the charger directly determines the service life of the lithium battery, so it is very important to choose a good quality charger. How to choose the charger? Is there any method? Pay attention to Lithium Electric Magong and share it with you. The output voltage of the charger must be matched according to your battery, and this must be grasped accurately. How to choose a good quality lithium battery charger?
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 larger the charging current, the faster the charging speed. The length of the charging time is not only related to the charging speed, but also depends on the capacity of the lithium battery.
It should be noted that the larger the charging current, the higher the internal system design quality requirements of the charger and lithium battery. In general, the larger the charging current, the more heat may be caused during the charging process, and the greater the damage to the battery performance may be. Poor quality chargers and batteries are prone to leakage and other safety performance problems when charging quickly with high current.
Look at the charging efficiency of the charger
During charging, not all the energy input to the lithium battery is converted into the energy stored in the battery. Some of it is used for the side reactions inside the battery and converted into heat during the charging process, so the charging efficiency is always less than 100%.
During 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, the charging method of the lithium battery charger needs to be specially designed to improve the charging efficiency.
Look at the charging termination control of the charger
Chargers with low current generally use time control. The larger the current provided by the charger, the more complex the charging termination control method, the higher the cost and price. For users, they should make choices based on 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 high-priced fast charger, learn more about the performance of the charger and lithium battery.
Judge the quality of the charger
A good electric vehicle charger uses positive and negative pulse technology, which can effectively prevent, inhibit and eliminate battery sulfation and polarization. It can keep the capacity of new batteries stable for a long time; it can restore the capacity of old batteries that have been polarized and have decreased in capacity, effectively extending the battery life by 2 to 3 times. It has intelligent timing protection, automatic temperature compensation, instantaneous power grid impact protection, super moisture and corrosion resistance, and other functions.
Charging cable
The same is true for charging cables. Choose original or packaged charging cables. If they are similar charging cables, they should be marked on them to avoid confusion.
The above is the selection method of lithium battery chargers. It should be noted that the charging process of lithium-ion batteries is completely different from that of nickel-cadmium and nickel-metal hydride batteries. It is a complex electrochemical reaction process. Therefore, a dedicated charger is required for charging.
