Explore our flagship CCS2 charging cable series — engineered for seamless battery pack and module connections across EV, energy storage, and industrial applications.
The Combined Charging System Type 2 (CCS2) charging cable is the European and globally adopted standard for DC fast charging of electric vehicles and battery-based energy systems. Defined under IEC 62196-3, the CCS2 connector integrates both AC and DC power delivery through a single, unified interface — making it the backbone of modern EV charging infrastructure and advanced battery module interconnection.
In the context of battery pack and module connections, CCS2 cables serve a dual role: they enable rapid energy transfer from charging stations to EV battery packs, and they function as critical internal harness elements within battery management systems (BMS), linking individual cell modules, thermal management units, and monitoring electronics. This makes the CCS2 charging cable not just a user-facing charging tool, but an engineering-critical component inside next-generation battery architectures.
SANCO's CCS2 charging cable lineup is designed with industrial-grade copper conductors, high-temperature silicone or TPE insulation, and precision-molded connectors that ensure minimal resistance, superior thermal stability, and long service life — even under the demanding cycles of commercial fleet charging or stationary energy storage dispatch.
Modern battery packs for electric vehicles, grid-scale energy storage systems (ESS), and industrial UPS platforms demand cable assemblies that can handle voltages up to 1000V DC and currents exceeding 500A. SANCO's CCS2 charging cables are engineered to meet these parameters with robust shielding against electromagnetic interference (EMI), flexible yet durable jacket materials, and locking mechanisms that guarantee secure mating even under vibration and thermal cycling.
The Cell Contact System (CCS) — a distinct but related technology — refers to the integrated harness assemblies that physically connect individual battery cells within a module. These CCS assemblies incorporate voltage sensing wires, temperature sensor leads, and current-carrying busbars into a single compact structure. SANCO manufactures both CCS charging cables for external charging interfaces and CCS internal harnesses for battery module integration, offering customers a complete connectivity solution from the charging port to the cell level.
Rated voltage up to 1000V DC · Current capacity up to 500A · Operating temperature -40°C to +125°C · IEC 62196-3 compliant · EMI shielded · IP67/IP69K sealing available · RoHS & REACH compliant materials

The CCS2 charging cable market is at the center of the global energy transition. Here's what's shaping demand in 2024 and beyond.
Global EV sales surpassed 14 million units in 2023, with Europe and Asia-Pacific leading CCS2 adoption. Regulatory mandates — including the EU's Alternative Fuels Infrastructure Regulation (AFIR) — require CCS2 as the mandatory DC fast-charging standard at public charging stations, creating massive demand for high-quality CCS2 cable assemblies from OEMs, charging network operators, and fleet managers.
Leading battery manufacturers including CATL, BYD, LG Energy Solution, and Panasonic are increasingly integrating Cell Contact System (CCS) harnesses directly into module assembly lines. This shift from discrete wiring to integrated CCS assemblies reduces weight, improves thermal management, and accelerates production throughput — driving demand for precision CCS cable suppliers like SANCO.
The transition from 400V to 800V battery architectures — pioneered by Porsche Taycan, Hyundai Ioniq 6, and Kia EV6 — demands CCS2 cables rated for higher voltages and capable of handling charging currents above 350A. This trend is pushing cable manufacturers to develop new conductor materials, insulation systems, and connector designs that maintain safety and performance at unprecedented power levels.
Utility-scale battery energy storage systems (BESS) are being deployed globally to support renewable energy integration. These systems use CCS2-compatible cable assemblies for inter-module connections, rack-to-rack wiring, and grid interface connections. The BESS market is projected to exceed $120 billion by 2030, representing a significant growth opportunity for CCS2 cable manufacturers with industrial-grade product lines.
Electric buses, heavy-duty trucks, and logistics vehicles require high-capacity CCS2 charging cables capable of 150kW to 350kW charging sessions. Fleet operators demand cables with enhanced durability, IP69K sealing, and extended service intervals. SANCO's industrial CCS2 cable series addresses these requirements with reinforced outer jackets, strain relief systems, and high-cycle connector mechanisms.
Industry consortia and regulatory bodies are converging on CCS2 as the universal DC fast-charging standard. The adoption of ISO 15118-20 for Plug & Charge (PnC) communication and bidirectional V2G (Vehicle-to-Grid) charging is further elevating the technical requirements for CCS2 cable assemblies, including enhanced signal integrity, additional pilot conductor specifications, and thermal monitoring integration.
CCS2 charging cables for battery pack and module connections are deployed across a wide spectrum of industries and use cases.
In passenger electric vehicles, CCS2 cables connect the vehicle's onboard charger and DC-DC converter to the high-voltage battery pack. Internally, CCS harness assemblies link individual cell groups within each module, carrying voltage and temperature signals to the BMS. SANCO's CCS assemblies are designed to fit within the tight spatial constraints of modern skateboard-platform battery architectures, with flat cable routing, integrated connectors, and vibration-resistant terminations.
In containerized BESS installations, CCS2 cable assemblies serve as the primary interconnect between battery racks, power conversion systems (PCS), and grid connection points. These applications demand cables rated for continuous high-current operation, UV resistance for outdoor installations, and flame-retardant properties for safety compliance. SANCO supplies custom-length CCS2 assemblies with industrial-grade connectors for BESS integrators worldwide.
Modern hybrid and battery-electric rail vehicles use high-voltage battery modules for traction energy storage and regenerative braking. CCS2 cables in these applications must withstand mechanical shock, high-frequency vibration, and wide temperature swings. SANCO's rail-grade CCS2 cable assemblies are qualified to EN 50343 and EN 50155 railway standards, ensuring reliable performance across the full operational lifecycle of rolling stock.
Public charging stations deploying CCS2 connectors require tethered cables that combine flexibility for user convenience with the durability to withstand thousands of daily connect/disconnect cycles. SANCO's CCS2 tethered cable assemblies feature high-flex TPE outer jackets, anti-kink strain relief, and gold-plated contact surfaces that maintain low contact resistance over the cable's service life — critical for station operators seeking to minimize maintenance costs and maximize uptime.
Vehicle-to-Grid (V2G) and Vehicle-to-Load (V2L) technologies require CCS2 cables capable of bidirectional power flow, with additional signal conductors for ISO 15118 communication protocols. SANCO's CCS2 cable assemblies for V2G applications incorporate all required pilot conductors, proximity detection wires, and communication shielding to support both charging and discharging modes — enabling EVs to serve as mobile energy assets for homes, businesses, and grid stabilization.
Battery pack manufacturers require specialized CCS2 cable assemblies for end-of-line testing, formation cycling, and quality validation of finished battery packs.
