How to choose a good quality lithium-ion battery charger?
1. Look at the charging speed of the charger
Common chargers use constant current charging mode, charging speed is important and lithium-ion battery charger supply current related. The higher 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-ion battery.
2. Look at the charging efficiency of the charger
The energy input to the lithium-ion battery during charging is not all converted into the energy stored in the battery, and part of the energy is respectively used for the side reaction inside the battery and converted into the heat in 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 the fast charger with a large current, the charging mode of the lithium-ion battery charger should be specially designed so as to improve the charging efficiency.
3. Look at the termination control of the charger
The charger with a low current generally adopts time control mode. The larger the current supplied by the charger, the more complex the charging termination control, and the higher the cost and price. Regarding the user, want to carry on the choice according to own actual situation.
4, judge the quality of the charger
A good electric car charger uses positive and negative pulse technology, which can effectively prevent, inhibit and eliminate battery vulcanization and polarization. The capacity of the new battery can be kept stable for a long time. Restore the capacity of the old battery which has been polarized and reduced incapacity, and effectively prolong the service life of the battery by 2-3 times. With intelligent time protection function, temperature automatic compensation function, power grid instantaneous impact protection, super moisture and corrosion prevention, and other functions.
5. Charging cable
The charging line is the same, it is best to choose the original or set of charging lines. If be similar charge line, should mark well above, lest get confused
