NACS  stands for North American Charging Standard . It's a charging connector and protocol that Tesla developed and has recently opened up to other automakers in 2022. and standardized as SAE J3400 in late 2023 by SAE Internation.    This move is aimed at standardizing EV charging in North America especially in the US, and making it more accessible for EV owners.  NACS offers a streamlined and efficient charging solution for EVs.   Key Features of NACS: NACS Charge Port with Cable from Fiver 200A 250A 300A 350A NACS Connector from Fiver Single-Port Design: NACS utilizes a single port for both AC and DC charging, simplifying the charging process for EV owners. Higher Power Capacity: NACS supports higher power levels, enabling faster charging speeds compared to older standards. Improved Safety Features: The NACS standard incorporates advanced safety features, such as robust mechanical interlocks and robust electrical insulation. Enhanced User Experience:...

In the evolving landscape of electric vehicles (EVs), the North American Charging Standard (NACS) inlet has emerged as a significant development, offering compatibility for both AC and DC charging. This compatibility is achieved through a combination of carefully designed features and protocols. 1. Pinout and Contact Function Definitions NACS Inlet Pinout The NACS charge inlet has a specific pinout with defined contact functions that support both AC and DC charging. DC+/L1 and DC−/L2 : In DC charging, these are the positive and negative terminals for the DC voltage feed respectively. In AC charging, DC+/L1 serves as Line 1 in split-phase or sole line in single-phase, and DC−/L2 serves as Line 2 in split-phase or neutral in single-phase. Ground (G) : It provides a connection to earth and acts as a reference point for control signals in both AC and DC charging. Control Pilot (CP) : This contact enables digital communication between the charging system and vehicle. In DC charging, it tra...

    In the world of electric vehicles (EVs), the question of whether a NACS extension cable is safe is an important one.  Why you need a NACS Extension Cable 1. The Need for Extension Cables Often, EV owners find themselves in situations where the charger is just out of reach in a parking lot. An EV charging extension cable seems like a solution, but concerns about its safety arise.  2. Potential Risks with General Extension Cords   Using a regular extension cord for EV charging is generally not recommended by manufacturers. EVs have higher power requirements, and extension cords designed for lower-current appliances may not provide sufficient power. This can lead to issues such as: Fire Hazards: The high current demands of EVs can cause the insulation of an extension cord to melt, increasing the risk of fire. Even high-capacity extension cords are not designed for the prolonged, continuous use required for EV charging. Electric Shock Hazards: The increased curr...

The electric vehicle (EV) industry is in the midst of a technological revolution, and at the heart of this transformation is the need for faster, more efficient charging solutions. Enter the liquid cooled charging cable, a groundbreaking innovation that is redefining the landscape of high-amperage EV fast charging. This blog will delve into the significance of this technology and how it is shaping the future of electric vehicle charging. The Power of Liquid Cooling:   Traditionally, EV charging cables have relied on air cooling to manage heat generated during the charging process. However, as EVs demand higher amperage for faster charging, air cooling alone is no longer sufficient. Liquid cooled charging cables represent a quantum leap forward, utilizing a liquid coolant to dissipate heat more effectively, allowing for significantly higher power transfer without overheating.

  The following are the factors that affect the charging speed of electric vehicles: I. Vehicle-related factors 1. Battery capacity: - The larger the battery capacity, the longer the charging time usually takes. Just like a large water tank needs more time to be filled with water, a high-capacity battery needs to receive more electricity, resulting in an extended charging time. - For example, an electric vehicle equipped with an 80kWh battery will have a significantly longer charging time compared to a vehicle with a 40kWh battery under the same charging conditions. 2. Battery technology: - Different battery technologies have a significant impact on charging speed. Currently, lithium-ion batteries are the most commonly used battery type in electric vehicles, but different chemical compositions and structures of lithium-ion batteries can lead to differences in charging performance. - For example, Li Auto Mega adopts the  advanced  5C  CATL Kirin battery technolog...

  In order to figure out whether a NACS DC adapter will lower the charging speed or not, first we need to clarify the point what is a NACS Adapter. What is a NACS DC Adapter? A NACS DC adapter is a device that allows electric cars with CCS1 charing port to charge on Tesla Supercharger or DC fast charger with NACS connector . it helps the CCS1-equipped Vehicle owners to access the Supercharger networks easily.  In terms of its structure，the NACS DC Adapter, one end is a CCS1 female (connect to the CCS1 Vehicle), the other end is a NACS male end ( connect to the Tesla charging pile). In essence, it acts as a bridge between the two charging standards, enabling CCS-equipped vehicles to utilize Tesla's extensive Supercharger network. This is particularly useful for EV owners who may not have access to a large network of CCS charging stations in their area. Will a NACS to CCS1 Adapter  lower the Charging Speed? The answer is, Yes! A NACS to CCS1 adapter can potential...

  What is NACS Charging Standard? NACS is short for the  North American Charging Standard  (NACS), currently being standardized as SAE J3400. NACS is also known as the Tesla charging standard, as it was originally a proprietary design by Tesla. Now more and more EV manufacturer such as Ford, Volkswagen, GM and charging network operators are adopting this NACS   Charging standard. What is NACS Connecto r? NACS Connector  is a compact and versatile charging connector that can support both alternating current (AC) and direct current (DC) charging. With AC charging, NACS can provide up to 80 amps at 240 volts, which is suitable for residential and public level 2 charging stations.  With   DC Fast Charging , NACS can provide up to 500 amps at up to 1000 volts, which is comparable to the Combined Charging System (CCS) standard. NACS can also communicate with the charging station and the vehicle to adjust the charging power and state.  it has a buil...
