Electric vehicles (EVs) are becoming more popular and affordable, thanks to advances in battery technology and environmental awareness. However, one of the challenges that EV owners face is finding a convenient and reliable way to charge their vehicles at home or on the go.
Most EVs come with a standard Level 1 charger, which plugs into a regular 120 V AC outlet and can deliver about 5 miles of range per hour of charging. This is fine for overnight or occasional charging, but it can be slow and inefficient for daily or long-distance driving.
That’s why many EV owners opt for a Level 2 charger, which requires a 240 V AC outlet and can deliver up to 25 miles of range per hour of charging. Level 2 chargers are faster, more energy-efficient, and more compatible with different EV models than Level 1 chargers.
However, not all Level 2 chargers are the same. There are different types of connectors, cables, and features that can affect the performance and convenience of charging your EV. In this article, we will review some of the latest developments and innovations in Level 2 charging cables, and how they can benefit EV owners and drivers.
What are Level 2 charging cables?
Level 2 charging cables are the cords that connect your EV to a Level 2 charging station, which can be installed at your home, workplace, or public location. Level 2 charging cables have two ends: one that plugs into the charging station, and one that plugs into your EV’s charging port.
The end that plugs into the charging station is usually a standard NEMA 14-50 plug, which can handle up to 50 amps of current. The end that plugs into your EV’s charging port can vary depending on the type of connector that your EV uses.
There are two main types of connectors that are used by most EVs in the U.S.: the J1772 connector and the NACS/CCS connector. The J1772 connector is a five-pin plug that can transfer both power and data between the EV and the charging station. The NACS/CCS connector is a seven-pin plug that can transfer both power and data, as well as support DC fast charging, which can deliver up to 80% of battery capacity in 30 minutes.
The type of connector that your EV uses depends on the make and model of your vehicle. Some examples of EVs that use the J1772 connector are the Chevrolet Bolt, the Nissan Leaf, and the Tesla Model 3 (with an adapter). Some examples of EVs that use the NACS/CCS connector are the Ford Mustang Mach-E, the Hyundai Kona Electric, and the Volkswagen ID.4.
The table below summarizes the main differences between the J1772 and the NACS/CCS connectors.
| Connector | Pins | Power | Data | DC Fast Charging |
|---|---|---|---|---|
| J1772 | 5 | AC | Yes | No |
| NACS/CCS | 7 | AC/DC | Yes | Yes |
What are the benefits of Level 2 charging cables?
Level 2 charging cables offer several benefits over Level 1 charging cables, such as:
- Faster charging: Level 2 charging cables can deliver up to 25 miles of range per hour of charging, compared to 5 miles of range per hour of charging for Level 1 cables. This means that you can fully charge your EV in a few hours, instead of overnight or longer.
- More energy-efficient: Level 2 charging cables can reduce the energy loss and heat generation that occur during the charging process, resulting in lower electricity bills and less environmental impact.
- More compatible: Level 2 charging cables can work with different types of EVs, as long as they have the same type of connector. This means that you can share your Level 2 charging station with other EV owners, or use public Level 2 charging stations without worrying about compatibility issues.
What are the latest innovations in Level 2 charging cables?
Level 2 charging cables are constantly evolving and improving, thanks to new technologies and features that enhance the charging experience. Some of the latest innovations in Level 2 charging cables are:
- Smart charging: Some Level 2 charging cables have built-in Wi-Fi or Bluetooth connectivity, which allows them to communicate with your smartphone, your EV, or your home network. This enables you to monitor and control your charging remotely, schedule your charging for off-peak hours, track your energy usage and costs, and receive alerts and notifications.
- Alexa and Google Home integration: Some Level 2 charging cables are compatible with voice assistants like Alexa and Google Home, which allows you to use voice commands to start, stop, or check your charging status, as well as access other features and functions.
- Universal compatibility: Some Level 2 charging cables are designed to work with both J1772 and NACS/CCS connectors, which means that they can charge any EV regardless of the type of connector. This eliminates the need for adapters or multiple cables, and increases the convenience and flexibility of charging your EV.
- UL certification: Some Level 2 charging cables are tested and certified by Underwriters Laboratories (UL), which is a global safety and quality organization. This means that they meet the highest standards of performance, reliability, and safety, and are suitable for use on UL-listed charging stations.
