BTUYDTUY CCS1-to-CCS2 EV Charging Adapter — DC 250A 1000V & AC J1772 32A, thermal safety

BTUYDTUY CCS1 to CCS2 Adapter is a dual-mode EV charging bridge that lets CCS2 vehicles accept CCS1 DC fast charging and Type 1 (J1772) AC charging—supporting up to 250A DC (1000V) and 32A AC (250V).

This compact, heavy-duty adapter removes a common compatibility obstacle for European CCS2 cars when using U.S. CCS1 stations or Type 1/J1772 chargers. Engineered for both DC and AC operation, it includes thermal safety monitoring, silver-plated contacts for low resistance, and a protective carrying case. It is a practical accessory for drivers who travel between different charging infrastructures or need flexible public charging options.

How does this adapter let my CCS2 vehicle use CCS1 fast chargers?

The adapter routes the CCS1 DC supply into a CCS2 inlet so a CCS2 vehicle can accept the DC fast charge from CCS1-equipped stations. Automatic switching ensures the correct pins are engaged for DC or AC sessions without manual reconfiguration.

• Supports DC charging at up to 250A and 1000V for high-power sessions.
• Automatically detects and switches between DC CCS1 and AC Type 1 (J1772) inputs.
• Designed to match CCS electrical pinouts and control signaling for safe power delivery.

What safety and durability features protect the adapter during use?

Safety is built into both the materials and control systems. The adapter monitors its internal temperature and suspends charging if thresholds are exceeded, restarting only after temperatures fall to safe levels and the vehicle re-establishes the charging handshake.

• Real-time temperature detection with automatic cut-off above 85°C and resume below 65°C.
• Silver-plated contacts for improved conductivity and a 0.15 mΩ contact resistance rating.
• V0 flame-retardant housing, anti-corrosion coating, and a rugged anti-impact carrying case.

Which charging modes and vehicles is this adapter compatible with?

The adapter works with DC CCS1 chargers and AC Type 1 (SAE J1772) plugs, enabling charging for CCS2 vehicles that otherwise could not accept those plug types. Compatibility depends on the vehicle’s onboard charging acceptance and local charging station capabilities.

• DC: CCS1 input to CCS2 vehicle inlet, up to 250A @ 1000V (peak capability).
• AC: Accepts Type 1/J1772 AC plugs and passes up to 32A @ 250V for AC charging.
• Check vehicle manufacturer specs for maximum allowable DC/AC current and software restrictions.

How should I install and care for the adapter to get reliable performance?

Installation is plug-and-play: insert the charging gun fully into the adapter, then connect the adapter to the vehicle’s CCS2 inlet. Regular inspection and proper storage extend service life; always follow station and vehicle guidance when initiating a charge.

• Ensure charging gun clicks fully into the adapter before starting a session.
• Store the adapter in the included anti-impact box when not in use to prevent physical damage.
• Inspect contacts and housing for debris or corrosion; clean per manufacturer recommendations.

Who is this for: The BTUYDTUY CCS1 to CCS2 Adapter is aimed at drivers of CCS2-equipped EVs who encounter CCS1 DC chargers or Type 1 AC points—frequent travelers between regions, fleet operators with mixed charging infrastructure, and EV owners seeking flexible public charging options. It is suitable for users who need durable, high-power bridging capability and integrated temperature protection; however, buyers should verify vehicle charging acceptance limits and local station compatibility before use.
