What is A DC EV Charger Station and How To Use It?

8 6 月, 2023

In everyday life, cars have a crucial impact on people, such as travel, transportation of goods, etc. Moreover, these new energy vehicles must be charged in time to maintain regular order, so whether the charging station achieves fast charging is always a concern.

To meet people’s needs, the DC EV charger was born, but many people need clarification on what it is and what is the charging principle; This article is about the DC EV charger for a detailed explanation, take a look at it.

What is a DC EV charger station?

A DC EV charger station, or a DC fast charging station, refers to a facility or location that houses multiple DC fast chargers for electric vehicles. It typically consists of several charging units or charging points installed in a designated area. These charging units are designed to provide high-power DC charging directly to electric vehicles, allowing for rapid charging times.

Its infrastructure includes power distribution systems, transformers, and other equipment necessary to handle the high-power demands of fast charging. It also incorporates communication systems to facilitate the interaction between the chargers and the vehicles, ensuring a safe and efficient charging process.

The DC EV charger station is a smart choice for people who want to charge quickly.

How to use the DC EV station?

Suppose you need to learn how to use the DC EV charger station. Here’s a step-by-step overview of how a typical DC EV charger works.

1. Vehicle connection

The EV owner connects their vehicle to the DC EV charger using the appropriate charging cable and connector. The charger is designed to be compatible with different charging standards, such as CCS (Combined Charging System) or Tesla Supercharger.

2. Authentication and payment

Some DC EV chargers may require authentication before initiating the charging session. This can be done using an RFID card, smartphone app, or other means of identification. Payment for the charging session may also be required, depending on the charger’s operation and payment model.

3. Power conversion

There are power electronics within the DC EV charger that convert the alternating current (AC) power from the electrical grid into a high-power DC suitable for charging EV batteries. This conversion process typically involves rectifiers, inverters, transformers, and other components to achieve the desired DC power output.

4. Battery communication

The DC EV charger communicates with the electric vehicle’s battery management system (BMS) to ensure safe and efficient charging. This communication allows the charger to monitor the battery’s state of charge, temperature, and other parameters. It also enables the charger to adjust the charging parameters based on the vehicle’s requirements and battery condition.

5. Charging process

The DC EV charger delivers a high-power DC directly to the EV’s battery. This bypasses the onboard charger in the vehicle, allowing for faster charging speeds compared to standard AC charging. Depending on the charger’s power output and the vehicle’s charging capabilities, DC fast chargers typically provide charging rates ranging from 30 kW to 360 kW or even higher.

6. Charging completion and disconnection

Once the charging session is complete, the charger sends a signal to the EV to indicate that the charging process has finished. The EV owner can then disconnect the charging cable from the vehicle.

When to use the DC EV charger station?

DC fast charging stations are typically used when fast charging is required or preferred. Here are some scenarios for you:

1. Long-distance travel

When embarking on a road trip or traveling to a destination beyond the EV’s range, DC fast chargers offer quick and convenient charging.

2. High-traffic areas

DC fast chargers are commonly installed in busy urban areas, shopping centers, and other locations with high EV usage.

3. Inter-city travel

DC EV charger stations strategically placed along highways and major travel routes provide essential infrastructure for inter-city travel.

4. Commercial fleet charging

Businesses operating electric vehicle fleets, such as delivery services or ride-sharing companies, benefit from the fast charging capabilities of DC EV chargers.

5. High-power charging needs

EVs with larger battery capacities or high-performance models often require the higher power output provided by DC fast chargers.

DC EV charger stations optimize charging convenience and accessibility, ensuring EV owners have reliable and efficient charging options for their electric vehicles in various situations.

What is the type of DC EV charger station?

DC EV charger stations typically come in different types or standards, each using a specific connector and protocol for charging. The main types of DC EV charger stations include:

  1. CHAdeMO

CHAdeMO is a DC fast-charging standard primarily used by Japanese and Korean automakers. It features a unique connector design and is compatible with vehicles such as Nissan LEAF, Mitsubishi i-MiEV, and Kia Soul EV.

2. CCS (Combined Charging System)

CCS is a combined AC and DC charging standard widely adopted by many automakers, especially in North America and Europe. It combines a standard AC charging connector with two additional DC charging pins. As a result, CCS allows for both AC and DC charging, providing flexibility for different charging needs.

3. Tesla Supercharger

Tesla Supercharger stations are proprietary charging stations designed explicitly for Tesla electric vehicles. They utilize a unique connector and protocol compatible with Tesla vehicles, enabling high-speed DC charging for Tesla models.

4. GB/T

GB/T, or Guobiao, is China’s DC fast charging standard. Chinese automakers primarily use it, supporting AC and DC charging with a standardized connector.

These are the main types of DC EV charger stations, each with its connector and protocol. However, some charging stations may support multiple standards, providing compatibility with different EV models and allowing more EV owners to utilize the charging infrastructure.

What size DC charger stations should you get?

DC charger stations size

It is difficult to define its size, but there are several factors that you need to consider when determining the size or capacity of a DC fast charger station. I list them below.

1. Charging Power

The size of the DC fast charger station should be able to deliver the charging power required by the electric vehicles (EVs) it will serve. Different EV models have varying charging capabilities, so it is essential to consider the maximum charging power they can accept.

2. Charging Speed Requirement

Determine the desired charging speed based on your needs. A larger-capacity charger station with higher power output may be suitable if you expect a high volume of EV users or want to minimize charging time.

3. Charging Demand

Assess the expected demand for charging at the location where the charger station will be installed. Consider factors such as the number of EVs expected to charge simultaneously and the charging patterns of the users. This will help determine the number of charging points and the overall capacity required.

4. Cost and Budget

Consider the charger station installation and operation budget. Higher-capacity charger stations generally come with higher costs in terms of equipment and electrical infrastructure requirements.

How long does it take to charge an electric car with Level 3 charging?

The time required to charge a car using a DC EV charger depends on several factors, including the car’s battery capacity and the power of the charger being used.

Generally, most DC EV chargers can charge an electric car up to 80% of its battery capacity within 30 minutes. However, the actual charging time can still vary based on the specific electric vehicle and charger.

Some electric cars may have higher charging rates and power capabilities, resulting in faster charging speeds. Additionally, certain electric vehicles may have charging limitations imposed by their battery management systems to protect the battery’s lifespan.

To accurately estimate the charging time, it is recommended to refer to the charging specifications of your electric vehicle and the capabilities of the charger being used. Or consulting us to get the exact answer.
