Electric Vehicles Compatible with Fast Charging Networks
CCS Chargers - The Ultimate Guide
Introduction
While most electric vehicle (EV) chargingabout 80%happens at home, Combined Charging System (CCS) chargers play a vital role in providing quick top-ups during long road trips. In a vast country like the US, the ability to rapidly charge an EV is essential, especially for covering long distances. The CCS charging infrastructure enables fast charging and makes electric vehicles more practical for such journeys.
When the industry developed the CCS standard, the goal was to have a single connector type for both AC and DC charging. This universal connector was intended to be used by all EV manufacturers, promoting compatibility across the EV charging ecosystem.
Chapter 1: Understanding CCS Chargers
What is CCS (Combined Charging System)?
The CCS is a standardized system designed for fast-charging electric vehicles. It brings together alternating current (AC) and direct current (DC) charging into a single connector, ensuring compatibility with a wide range of EVs. CCS uses the Level 2 charger as its base, adding two extra DC power lines which enable it to carry a higher voltage compared to the regular connector. If you're using a standard Type 2 charger, the bottom two holes on the connector remain unused because they're only for the CCS plug.
In the US, CCS connectors are the primary high-speed chargers found in public charging stations. In a fast-paced country, the need for quick on-the-road top-ups has never been more apparent. According to S&P Global Mobility, there are currently around 20,000 fast charging ports nationwide, which is not enough to cater to the growing EV market share for new vehicles. By 2030, it's estimated that EVs will account for 40% of cars on the road, which translates to approximately 28.3 million EVs in operation.
Analysts predict that around 172,000 DC EV chargers will be needed to meet the charging demands by the same year. This means the US must quadruple this number between 2022 and 2025 to meet the immediate charging needs. By 2027, about 109,000 fast chargers will need to be deployed across the country to keep up with the escalating demand for electric car and charging points.
