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...
