2. Because there is a difference in charging speed between the fast charging head and the slow charging head.
The fast charging head can provide higher charging power, so electrical energy can be transferred to the battery faster, thereby reducing charging time.
The slow charging head has lower charging power and takes longer to complete the charging process. 3. There is a difference in the charging speed between the fast charging head and the slow charging head, so it is necessary to choose the appropriate charging method according to the specific situation in actual use.
If you need fast charging, you can choose fast charging head; If you have enough time, you can choose a slow charge head to reduce the loss of the battery. In addition, it is also necessary to consider whether the charging interface of the device is compatible with different types of charging heads.
Electric vehicle charging port is generally only one, of course, there are some cars will be equipped with fast and slow two ports, for the charging pile port is generally in line with the national standard, fast and slow gun head is the same.
