CCS2 Charging Standard

The Combined Charging System (CCS) is a fast charging standard for electric vehicles that combines AC and DC charging into a single connector. CCS2 is widely considered the global standard for DC fast charging, and has been adopted by most major automakers in Europe, Australia, South America and South Africa etc..
CCS2 offers two key advantages compared to other charging standards:
- Combines AC and DC charging in one connector: The single CCS2 connector supports both slower Level 2 AC charging up to 22 kW, as well as high-power DC fast charging up to 350 kW. This eliminates the need for separate AC and DC charge ports.
- High power DC fast charging: CCS2 supports charging at up to 350 kW or even higher, allowing an EV battery pack to charge from 10% to 80% in around 15-30 minutes. This enables long distance travel by providing quick charging stops.

Power up Electric Truck with CCS Type 2 Charging Socket

“Our team is currently working on developing an electric truck prototype for the year 2024. We are currently in search of a "Charging Socket" for our prototype. Upon reviewing your products on your website, our team has taken an interest in them.”
Case Study: Prototype Electric Truck
An exciting prototype electric truck currently under development is using the DC 300A CCS Type 2 charging socket. This heavy-duty electric truck is designed for long haul transport and needs to charge quickly during short rest stops.
The engineers selected the CCS2 standard for its high power capacity and wide industry adoption. The DC pins allow for quick charging, while the AC pins provide a fallback charging option.
During prototype testing, Guchen CCS type 2 socket has performed well in harsh driving conditions and repeated charging cycles. The latching mechanism and rugged housing protect the contacts from vibration, dirt, and weather.
So far, the electric truck successfully meets range targets thanks to its powerful battery pack and fast 300A charging. The CCS2 socket plays a key role by enabling high-speed charging at terminals equipped with CCS2. This electric truck could transform long-haul transportation when put into full production.

The CCS Type 2 DC charging socket provides several key benefits for electric truck charging:
- High power delivery & faster charging times
With support for up to 500A charging, this socket enables much faster charging compared to lower amperage alternatives. This helps reduce downtime when charging electric truck fleets.
- CCS standard compatibility
The socket uses the Combined Charging System (CCS) connector type, which is becoming the dominant DC fast charging standard globally. This ensures compatibility with many existing and future charging stations.
- Rugged durability
Electric truck charging ports experience significant wear and tear. This socket is designed to withstand vibration, shocks, and weather elements to provide maximum uptime.

The Future

The future looks bright for advancements in electric truck charging technology. As more manufacturers begin producing electric trucks, there will be greater demand for higher powered DC fast charging stations. This will drive innovation to create chargers that can deliver higher charging power to minimize charging times. We'll also see new EV connector designs that are optimized for high-power charging and can withstand daily heavy use.
The CCS2 female and male connectors are likely to remain the standard, but may evolve to handle greater amperages. Liquid-cooled cables and connectors will help prevent overheating during ultra-fast charging sessions.
Charging networks will expand dramatically to support long-haul electric trucking. Chargers will need to be located at strategic intervals along major highways and transport routes. This infrastructure build-out will be key to enabling widespread adoption.
Battery technology improvements will also allow electric trucks to travel farther between charges. New battery chemistries, cell designs, and advanced cooling systems will increase range and cycle life.
Overall, electric truck charging is poised to improve by leaps and bounds. The next decade will see major progress as manufacturers and charging networks invest heavily to electrify commercial transport. This will reduce operating costs, improve efficiency, and provide environmental benefits over diesel trucks.
