Vehicle charging stations are mainly divided into two categories: AC charging stations and DC charging stations. The core difference between these two types of charging stations lies in their charging speed. AC charging stations belong to slow charging, while DC charging stations can achieve fast charging. Specifically, it takes 7 to 10 hours for an AC charging station to fully charge the battery, while a DC charging station only takes 1 to 2 hours to complete the charging process.

However, in terms of charging time, DC charging stations do not always have an advantage. In practical applications, both types of charging stations have their own applicable scenarios. The AC charging station, as a representative of "slow charging", serves to provide AC power for the on-board charger of electric vehicles. It does not directly participate in the charging process, but plays the role of controlling the power supply and needs to be combined with the on-board charger to charge electric vehicles.

In contrast, DC charging stations, also known as "fast charging", can directly provide DC power to the power batteries of electric vehicles. Its input voltage and frequency meet the standards, and its output is adjustable DC power, which can meet the needs of fast charging. Due to the use of a three-phase four wire power supply, the DC charging station can provide sufficient power and a wide range of voltage and current adjustment, thereby achieving fast charging.

Introduction to 7Kw, 15Kw, and 20Kw portable DC charging stations

The portable DC charging station provides a convenient charging solution for electric vehicles with different power options of 7Kw, 15Kw, and 20Kw. This type of charging station can directly supply DC power to the power battery of electric vehicles. Its input voltage and frequency strictly follow the standards, and the output is adjustable DC power, perfectly meeting the fast charging needs. In addition, the portable design allows these charging stations to easily handle various situations, bringing great convenience to electric vehicle users.
