For the newly purchased lithium battery electric car, many users are concerned about how long it takes to charge for the first time. This is not only related to the efficiency of the battery, but also closely related to the life of the battery. Below, we will discuss in detail the correct way to charge the lithium battery for the first time and its precautions.

First of all, regarding the first charging time of lithium batteries, different batteries and chargers may vary. Generally speaking, it is recommended to control the charging time between 6 to 10 hours. This is because new batteries have a higher electrical capacity and may reduce their cycle life if the charging time is insufficient. However, care also needs to be taken not to overcharge, as a full charge can usually be achieved in about 8 hours and should not exceed a maximum of 12 hours, otherwise battery life will be affected.

Secondly, a suitable charging environment should be chosen when charging. Lithium batteries will produce chemical reactions when charging, especially its highly active cathode materials and organic electrolyte may trigger violent side reactions when heated. Therefore, make sure to choose a well-ventilated, cool and moderate temperature place for charging to ensure the heat dissipation effect. At the same time, avoid charging in extreme environments such as high temperatures, strong sunlight or rain to ensure safety.

Furthermore, it is important to use a charger that is compatible with the battery specifications. Three-stage chargers are often recommended for electric vehicles, with a charging process that includes constant-current, constant-voltage and trickle-current stages, which helps to extend battery life. Avoid incompatible chargers, such as lead-acid battery chargers, to eliminate circuit safety hazards.

There are also some additional precautions. For example, after riding, the battery should be allowed to cool down for half an hour before charging; when charging, the battery end plug should be connected before turning on the power; for batteries that are not used for a long period of time, it is recommended that they be charged one to two times a month to maintain their power status; and charging the battery in a timely manner when about 20% of the battery power is left in the charge, to avoid deep discharging the battery, and so on.

By reasonably planning the charging time, choosing the appropriate charging environment and using a matching charger, we can effectively improve the performance of lithium batteries and extend their service life. I hope this article can help you better understand the knowledge of lithium battery charging.
