As new energy vehicles become increasingly popular, EV chargers, serving as their indispensable gas stations, play an essential role in daily use. However, when faced with a wide range of single-port and dual-port EV chargers on the market, many car owners may feel confused: What are the differences between them? How can you make a wise choice based on your own needs? This article provides a detailed explanation of the differences between single-port and dual-port EV chargers, as well as their respective advantages and applicable scenarios, to help you navigate the charging process of new energy vehicles with greater ease.
A single-port EV charger, as the name implies, refers to a charger with only one charging connector. It typically provides charging services for one new energy vehicle, and its charging power corresponds to the maximum output power of the device. This type of charger features a simple structure, easy installation, and relatively low cost, making it suitable for household users or locations with low charging demand.
A dual-port EV charger is equipped with two independent charging connectors and can charge two new energy vehicles simultaneously. Its charging power is the sum of the output power of the two charging connectors, but when charging two vehicles at the same time, the maximum output power of each connector is equally divided from the device's total output capacity.
The original intention behind the design of dual-port EV chargers is to meet the need for simultaneous charging of multiple vehicles and to improve the utilization efficiency of chargers. They are particularly suitable for public locations such as residential parking lots, shopping malls, and company campuses.
Now that we have established a basic understanding of single-port and dual-port EV chargers, we must delve into a crucial question: What are the main differences between these two types of chargers? These differences are far from negligible; they largely determine charging performance, applicable scenarios, cost-effectiveness, and many other key factors.
A single-port EV charger delivers its full output power to one new energy vehicle, enabling fast charging. For example, a 14 kW single-port charger can use its full power to charge one vehicle, resulting in higher charging speed.
A dual-port EV charger, however, divides its power when charging two vehicles simultaneously. For instance, for a 14 kW dual-port charger, each vehicle theoretically receives 7 kW when both are charging at the same time (actual values may vary slightly depending on the battery state). Therefore, if only one vehicle needs charging, a single-port charger will charge faster.
However, the advantage of dual-port chargers lies in their ability to charge two vehicles at once, greatly improving overall efficiency. For example, if your household has two electric vehicles or if a residential parking lot needs to serve multiple vehicles, a dual-port charger can charge more cars within the same time frame and reduce waiting time.
Single-port EV chargers are more suitable for household users. If your home has only one electric vehicle or low charging demand, a single-port charger, with its simple installation, low cost, and ease of use, is more than sufficient.
Additionally, single-port chargers are intuitive to operate, making them ideal for users who are not very familiar with technology. For example, in older residential complexes with tight parking spaces, installing a single-port charger can save space while meeting daily charging needs.
Dual-port EV chargers are better suited for public locations such as residential parking lots, shopping malls, and company campuses. These places typically require charging support for multiple vehicles. Dual-port chargers can serve two vehicles simultaneously, improving utilization efficiency and reducing queue time.
For example, in shopping mall parking lots, customers can charge two vehicles at the same time while shopping, significantly improving convenience.
In terms of cost, although dual-port EV chargers are more expensive per unit, the overall site construction cost is lower. For example, a dual-port charger requires only one set of cables and one electricity meter, while two single-port chargers require two sets.
Over the long term, maintenance costs for dual-port chargers are also lower because the number of devices is cut in half.
However, for household use, the single-port EV charger still offers better cost-effectiveness.
Dual-port EV chargers usually come with more intelligent features, for example, activation via mobile app, card swiping, plug-and-charge functionality, and real-time display of charging status. Some dual-port chargers support 4G connectivity and OTA remote upgrades, with protection ratings of up to IP54 for dust and water resistance, making them suitable for outdoor use.
These smart features not only enhance user experience but also facilitate management and maintenance.
Single-port EV chargers, while simpler in function, offer more straightforward operation, ideal for users unfamiliar with technology. Many single-port models include simple displays and physical buttons, allowing users to complete charging steps easily.
Many car owners worry that when a dual-port EV charger charges two vehicles simultaneously, a power-grabbing phenomenon may occur, resulting in slower charging. In fact, such concerns are unnecessary. Dual-port EV chargers are designed to efficiently meet multi-vehicle charging needs, rather than to create power competition between vehicles.
An AC dual-port EV charger is not two independent charging devices stuffed into one housing; rather, it is a complete charging system paired with two control modules. These two modules operate under the same standards and correspond to the two charging connectors.
During charging, if both connectors are working simultaneously, their voltage and maximum current are generally the same. Conversely, if only one connector is in use, the system does not double up its power.
In other words: When one vehicle uses a dual-port EV charger, both modules operate together, and the current is divided by two. When two vehicles charge at the same time, the current is multiplied by two, but each car receives half. As long as the two vehicles have charging components that follow the same standards, they will receive the same charging speed even when sharing one charger.
Of course, if the vehicles differ, their charging component standards may differ as well. This can lead to differences in charging speed when both use the charger simultaneously, creating a situation where one charges faster and the other slower, resulting in different currents. This may give the impression of power grabbing.
Some chargers also allocate power based on preset rules, where the vehicle that begins charging first receives more power, or dynamic allocation, distributing more power to the vehicle with lower battery level.
Choosing between a single-port or a dual-port EV charger requires a comprehensive evaluation of your actual needs, usage scenarios, and budget.
If your home has only one electric vehicle or low charging demand, a single-port EV charger is a good choice. It is easy to install, cost-effective, and sufficient for daily charging needs. Additionally, its straightforward operation makes it suitable for users who are not tech-savvy.
If you manage public areas such as residential parking lots, shopping malls, or company campuses, dual-port EV chargers are more suitable. They can charge two vehicles at once, improving utilization and reducing waiting time. Though the unit price is higher, overall site construction and long-term maintenance costs are lower.
If you need advanced smart functions, such as mobile app activation, card charging, plug-and-charge, real-time monitoring, 4G connectivity, or OTA upgrades, a dual-port EV charger is a better option. Its IP54 protection makes it suitable for outdoor environments as well.
If you have a limited budget, a single-port EV charger offers better cost-effectiveness due to its simplicity, easy installation, and lower overall cost. If your budget is ample, a dual-port EV charger, despite its higher unit price, offers lower overall construction and maintenance costs and may be more economical in the long run.
Both single-port and dual-port EV chargers have their own advantages and are suitable for different usage scenarios and demands. Single-port EV chargers feature simple structures, easy installation, and low cost, ideal for household users. Dual-port EV chargers can charge two vehicles simultaneously, improving utilization and making them suitable for public locations. Choosing the EV charger that best suits your needs requires considering your actual usage, environment, and budget. As new energy vehicles become increasingly common, EV chargers, an essential supporting facility, are also evolving. In the future, EV chargers will become more intelligent, efficient, and convenient, providing stronger support for the development of new energy vehicles. Whether you are a household user or a public facility manager, choosing the right EV charger will make your EV charging experience smoother. In short, both single-port and dual-port EV chargers have their strengths. Selecting the one that fits your needs will make charging easier and more efficient. We hope this article helps you make a wise choice on your journey toward new energy vehicle charging.
