With the growing variety of electric models, from urban minivans to luxury SUVs to performance sports cars, electric vehicles have become the preferred choice for many people's daily commute. With this comes an increased demand for charging infrastructure, especially charging guns, which are key devices that connect the EV to the power source.
Choosing the right charging gun is crucial for EV users. The right charging gun not only ensures an efficient and safe charging process, but also significantly improves the ease of use and overall user experience of the EV.
1. Understand charging standards and types
Understanding the different charging standards and types is crucial, as they directly determine whether the charging gun is compatible with your EV. The main charging interface types currently on the market include:
- Type 1 (J1772): this is a single-phase charging interface used primarily in North America that supports AC charging.
- Type 2 (Mennekes): more common in Europe, this interface supports single-phase and three-phase AC charging, with some configurations also supporting DC charging.
- CHAdeMO: This is a type of connector used primarily for direct current (DC) fast charging, and is widely used in certain electric vehicles in Japan and other countries.
- CCS (Combined Charging System): Combining AC and DC charging, the European version of the CCS interface is based on Type 2, while the North American version is based on Type 1.
Different charging interface types mean different charging capabilities and compatibility. Knowing which charging interface type your EV supports is critical to choosing the right charging gun.
Additionally, the difference between AC (alternating current) and DC (direct current) charging methods is an important consideration:
- AC charging involves delivering alternating current directly to the vehicle's built-in charger, which converts the AC to DC to charge the battery. This method is typically used for slow charging in homes and offices.
- DC fast charging, on the other hand, delivers DC power directly to the EV's battery, bypassing the vehicle's built-in charger for faster charging, and is typically used at public charging stations.
2. Charging Speed (Power)
Charging speed, or power, is one of the key factors affecting charging time. The higher the power, the faster the charging speed. The power of a charging gun is usually measured in kilowatts (kW), with the following common power levels:
- 3.6 kW: This is the lower power level and is suitable for slow charging at night for use at home.
- 7.2 kW: This provides a medium charging speed, suitable for homes and public places, and can fully charge an EV in a few hours.
- 22 kW: This is the higher AC charging power level, which requires three-phase power support and can provide a considerable range for an EV in less than an hour.
Which power level you choose depends on your specific needs, including the maximum charging speed supported by your EV and where you typically charge (home, office or public charging station).
3. Cable Length
The choice of cable length should be based on the layout of the parking lot and charging points, as well as the intended usage scenario. Below are some considerations and recommendations to help choose the best cable length for your needs.
- Parking LotLayout: Consider which locations you will typically charge at - home, work, or public charging stations. Each location may have different parking configurations and charging station locations, requiring different cable lengths to ensure the charging gun can easily connect to the EV.
- Distance of common charging points: assess the average distance from a parking space to a charging point. In some cases, the charging station may be right next to your parking space, while in other cases, a longer cable may be needed to span a distance.
- Intended use scenarios: If you travel a lot or charge in unfamiliar locations, consider choosing a longer cable to accommodate a variety of different charging environments and layouts.
Choice of cable length
- Standard length: Most charging cables offer a standard length of around 4 to 5 meters (about 13 to 16 feet), which is usually sufficient for everyday charging at home and office locations.
- Extension cable: If you determine that you need more flexibility, or if your parking space is farther away from the charging station, choosing an extension cable (e.g., 7 meters or longer) may be more appropriate. Extension cables can cover more charging scenarios, especially in public charging stations or irregular parking lots.
Flexibility and cost
While longer cables offer greater flexibility, enabling charging in almost any situation, they can present additional cost and storage challenges. Longer cables are typically more expensive and require more space to store, especially in the trunk of a vehicle. Additionally, longer cables may be more difficult to manage when in use, adding to the difficulty of placement and keeping things tidy.
A highly durable charging gun ensures long-term reliability and performance, even under frequent use or adverse weather conditions. Below are key points related to durability and how to recognize and maintain a highly durable charging gun.
Materials and build quality
- Materials: High-quality charging guns are typically manufactured using materials that are resistant to wear and corrosion, such as reinforced plastics, stainless steel, or aluminum alloys. These materials are able to withstand the wear and tear of everyday use as well as unfavorable environmental conditions.
- Manufacturing Quality: Fine craftsmanship during the manufacturing process is also critical to the durability of a rechargeable gun. Precise assembly, solid connections and strict quality control ensure the long-term reliability of the charging gun.
- Weather Resistance: Charging guns need to be able to withstand a wide range of weather conditions, including extreme temperatures, humidity, rain, snow and UV exposure. Highly weatherproof charging guns are designed with proper sealing and protection against water and dust.
