How to choose a good quality lithium-ion battery charger? The quality of the charger has determined the length of the life of the lithium-ion battery, so selecting a quality charger is very important. The output voltage of the charger must be matched according to your battery, this must grasp accurate. How to choose a good quality lithium-ion battery charger? 1.
The larger the charging current, the faster the charging speed is. The length of charging time is related to the speed of charging, and also look at the capacity of lithium-ion batteries. It should be noted that the larger the charging current, the higher the design quality requirements for the internal system design of the charger and lithium-ion battery.
In general, the larger the charging current, the more fever during charging, the greater damage to the performance of the battery. Quality Purifier Charger and Battery Easy to have a safe performance such as leakage liquid when it is rapidly charged. 2 Always less than 100%.
When charging, the charging current should be controlled within a certain range, and the charging current is too large or too small, which will reduce charging efficiency. Regarding the fast charger of the large current, it is necessary to perform a special design of the charging method of the lithium ion battery charger to improve charging efficiency. 3.
Watch the charger of the charger to terminate the charger of the small current generally use time control method. The larger the current supply of charger, the more complex the charging termination control method, the higher the cost and price. For the user, to choose according to your own actual situation.
If the battery capacity used is not very high, or the charging speed does not particularly value, a general charge can be selected; if necessary, there is a need to choose a fast charger, it is best to have more performance of the charger and lithium-ion battery. Have some understanding. 4.
Judging the electric vehicle charger of the charger quality is a positive and negative pulse technology, which can effectively guard, inhibit, eliminate the vulcanization of the battery, and the polarization. The new battery capacity can be maintained longer and stable; it is polarized, the capacity of the old battery capacity is restored, and the battery life is prolonged 2 to 3 times the battery life. Have intelligent on time protection, temperature automatic compensation function, grid instant impact protection, super anti-tide preventive corrosion resistance, etc.
5, charging wire charging line is also the same, it is best to use the original or suite charging cable. If it is a similar charging cable, it should be logified above to avoid mixing. Lithium-ion battery charging system pays attention to the input source: Many uses extremely cheap wall adapters as input power.
Its output voltage is important to rely on the AC input voltage and load current flowing from wall adapter. Rate and accuracy of constant current charging: Specific use topology selection may be determined by charging current. Many large constant current chargers or multi-section battery charging use use switching charging processing methods to achieve higher efficiency and prevent excessive heat.
The stability accuracy of the output voltage: In order to use the battery capacity as much as possible, the output voltage regulator accuracy is very critical. Small amplitude decline in output voltage accuracy can also cause a significant reduction in lithium-ion battery capacity. However, due to safety and reliability, the output voltage cannot be set high at will.
Battery temperature monitoring: Under normal circumstances, the temperature range at 0 ¡ã C to 45 ¡ã C during charging of the lithium ion battery. Charging battery can cause battery overheating in this temperature range. In the charging cycle, the pressure rise in the battery will also cause the battery to expand.
Temperature and pressure pen. The above is the choice of lithium-ion battery charger. To note that the charging process of the lithium-ion battery is completely different from the charging process of nickel-cadmium and nickel-hydrogen batteries.
It is a complex electrochemical reaction process. So to configure a dedicated charger for charging.
