Separates EV01, EV02, EV03 and variant evidence.
Connector project selection
EV High-Voltage Connectors
Compare EV01, EV02 and EV03 product selection points for an automotive high-voltage connector RFQ. Ratings, qualification and availability must be confirmed for the selected configuration.
Selection priorities
Define the key engineering inputs
Working voltage and dielectric withstand are different fields.
Catalog current values are configuration-dependent.
Define power, protective earth, control and communication circuits.
Needed for contact, seal, crimp and derating review.
Distinguish crimp, busbar, through-hole and mounting needs.
State the required High Voltage Interlock architecture; no current product implementation is presumed.
Define mated/unmated IP, temperature, fluids, salt fog, vibration and shock.
Project fit
Application and configuration review
The product source catalog presents EV01 for push-pull high-voltage power connections, EV02 for battery and battery-swap interfaces, and EV03 for AC and DC vehicle charging connections.
This category draft helps a buyer separate interface type, circuit allocation, termination, cable, movement, environment and documentation inputs before selecting a series for review.
Define the system’s rated working voltage and isolation requirement separately from dielectric withstand. The product EV01 value of 3,000 VAC and EV02 values of 4,000/1,500 VAC are dielectric-withstand values, not rated working voltages.
Engineering conversation
Translate the requirement into a configuration
HVIL, shielding, conductor size, temperature rise, derating, ingress protection, mating duty, interface drawings and material or automotive-compliance documents must be stated as requirements and confirmed for the selected configuration.
The source catalog provides contact-layout, termination, selected current or terminal-table values, environmental values, material descriptions and drawing references for the three product series.
Use the EV01, EV02 and EV03 series pages as separate evidence records: EV01 focuses on a push-pull power interface, EV02 on guided battery or power-control mating, and EV03 on charging-interface configurations.

Frequently asked questions
Plan the next engineering step
Is dielectric withstand the same as rated working voltage?
No. Dielectric withstand is a separate test value.
Which series should be reviewed first?
Use EV01 for a push-pull power-interface review, EV02 for a guided battery or battery-swap interface review, and EV03 for an AC/DC charging-interface review. The complete current part number and drawing still require confirmation.
Does the category page confirm HVIL, shielding or automotive qualification?
No. HVIL, shielding, temperature rise, derating and automotive or material-compliance coverage are requirements to confirm for the selected configuration.
Can values be combined across EV01, EV02, EV03 or their variants?
No. Contact layouts, current values, dielectric withstand, cable options and variant drawings remain separated until the exact current configuration is confirmed.
Does a product catalog establish availability, price or export eligibility?
No. Availability, configuration, documentation, commercial terms and export eligibility are confirmed case by case after the requirement is identified.
