EV (Electric Vehicle) Industry FAQ

This FAQ is designed to support sourcing decisions for electric vehicle (EV) and e-mobility applications, focusing on connectors, cables, wire harnesses, and related components used in automotive-grade systems.

1. What EV applications do you support?

We support a wide range of electric vehicle and e-mobility applications, including:

• Battery packs and battery modules

• Battery Management Systems (BMS)

• Power Distribution Units (PDU)

• On-board chargers (OBC)

• Inverters and motor control units (MCU)

• High-voltage junction boxes (HVJB)

• Signal and control harnesses

Our products are suitable for both passenger EVs and commercial electric vehicles.

2. What types of connectors are available for EV applications?

We supply connectors commonly used in EV systems, such as:

• High-voltage and high-current power connectors

• Signal and low-voltage connectors

• Shielded connectors for EMC-sensitive areas

• Automotive-grade wire-to-board and wire-to-wire connectors

Available brands include TE Connectivity, Amphenol, Molex, JST, Hirose, Sumitomo, as well as qualified alternative manufacturers.

3. Do you support high-voltage EV systems?

Yes.

We can support components suitable for high-voltage EV architectures, typically ranging from 400V to 800V systems. Products can be selected based on:

• Voltage and current rating

• Insulation and creepage requirements

• Temperature resistance

• Mechanical robustness

Please provide system specifications for confirmation.

4. Can you supply EV wire harnesses or custom cable assemblies?

Yes.

We support custom EV wire harnesses and cable assemblies, including:

• High-voltage battery cables

• Shielded motor and inverter cables

• Signal and control harnesses

• Prototype and low-volume production

BOMs, drawings, or sample references are welcome for quotation.

5. Are your products compliant with automotive standards?

Components supplied for EV applications can support requirements related to:

• Automotive-grade reliability

• Temperature and vibration resistance

• EMI / EMC performance

• Automotive electrical safety standards

Specific certifications or compliance requirements should be confirmed based on the selected part number.

6. Can you provide alternative parts if original brands have long lead times?

Yes.

When original branded connectors or cables have extended lead times, we can propose compatible alternative solutions with:

• Equivalent electrical and mechanical performance

• Proven usage in EV or automotive applications

• More flexible lead times

All alternatives are provided for customer evaluation and approval.

7. Are samples available for EV projects?

Samples may be available depending on the part number and project stage.

For custom EV harness or cable projects, samples can be prepared after technical confirmation. Please indicate sample requirements in your RFQ.

8. What information is required to quote an EV project?

To provide an accurate quotation, we recommend including:

• Manufacturer part number or complete BOM

• Quantity and estimated annual demand

• EV subsystem (battery, inverter, OBC, etc.)

• Voltage and current rating

• Operating environment and temperature range

Supporting drawings and datasheets help accelerate the quotation process.

9. Do you support prototype and pilot production?

Yes.

We support prototype, pilot, and low-volume production stages, helping customers transition from development to mass production.

10. Which markets do you serve for EV-related projects?

We primarily serve customers in Europe and North America, including:

• EV OEMs and Tier 1 / Tier 2 suppliers

• Powertrain and battery system manufacturers

• Automotive engineering and development companies
