The TeleEV Guide to DC Fast Charging and CCS Compatibility

As electric vehicles (EVs) continue to dominate the roads, the demand for efficient and rapid charging infrastructure has become increasingly evident. While home charging remains prevalent, the limitations of residential electricity supply necessitate faster solutions for on-the-go charging. Enter DC fast charging, a technology designed to meet the high-speed charging demands of EV drivers between stops.

Understanding DC Fast Charging:

DC fast charging, or direct current fast charging, stands as a crucial solution for electric vehicles requiring rapid charging on the road. In contrast to standard AC charging suitable for overnight use at home, DC fast charging is tailored for quick top-ups during your journeys. The fundamental process involves the following key steps:

  1. Conversion to DC: DC fast charging stations provide a direct current (DC) supply, matching the electricity stored in EV batteries. The vehicle's onboard charger then converts this DC power into a form suitable for battery charging.

  2. High Charging Power: DC fast chargers deliver significantly higher charging power compared to their AC counterparts. This elevated power enables swift charging rates, allowing substantial range additions in a short time.

  3. Wide Compatibility: With compatibility for connectors like CCS or CHAdeMO, DC fast charging accommodates a broad range of electric vehicles, promoting accessibility and convenience.

  4. Charging Speed: Charging speed varies based on the station's power rating and the EV's capabilities. Top-tier stations can charge a compatible EV from 10% to 80% in under 30 minutes.

CCS: Empowering Electric Vehicles with Versatile Charging:

CCS, or Combined Charging System, emerges as a standardized fast charging system for electric vehicles, incorporating both AC and DC charging capabilities. Noteworthy features of CCS include:

  1. Charging Power: The charging power provided by CCS charging stations ranges from 50 kW to 350 kW or more. Higher power levels result in faster charging, a crucial consideration for modern EVs equipped to handle elevated charging powers.

  2. Vehicle Compatibility: The charging speed also hinges on the compatibility of the EV model. Newer models are designed to maximize available power, ensuring optimal charging rates.

  3. State of Charge (SoC): Charging speed is influenced by the state of charge of the EV battery. Faster charging typically occurs when the battery is at a lower SoC.

  4. Temperature: Extreme temperatures can impact charging efficiency, with lower or higher temperatures potentially leading to slower charging rates.

CCS Charging Times – A General Overview:

For a glimpse into charging times with a 350 kW CCS charger, here are approximate times for various EVs:

  • Tesla Model 3: 20-30 minutes for an 80% charge.
  • Ford Mustang Mach-E: Approximately 20-30 minutes for 80% charge.
  • Audi e-tron: 30-40 minutes to reach an 80% charge.

These times are estimates and may vary based on factors such as charging power, vehicle compatibility, state of charge, and temperature conditions.

CCS Compatibility Beyond Boundaries:

While Tesla EVs enjoy exclusive access to the Supercharger network, CCS-compatible models can leverage third-party adapters like the TeleEV CCS to Tesla EV Adapter. This adapter boasts a charging rate of up to 150 kWh, with a maximum rating of 500V and 300A.

For non-Tesla owners seeking access to Superchargers, Tesla's introduction of the Magic Dock, along with third-party adapters like the TeleEV Vortex Plug, has expanded access to over 12,000 Tesla Superchargers nationwide for NACS-compliant carmakers like Hyundai, BMW, Toyota, and Kia.

In the evolving landscape of electric vehicle charging, embracing technologies like DC fast charging and ensuring compatibility with systems like CCS are pivotal steps toward a seamless and efficient charging experience. With solutions like the TeleEV adapters, the future of electric mobility is charged with innovation and accessibility.
