EPLAN Pro Panel Design Engineer – UL-Compliant DC Fast EV Chargers for USA (120–400 kW)

We are an EV DC fast charger manufacturer seeking an experienced EPLAN Pro Panel / Electrical Design Engineer with proven experience designing DC fast EV chargers for the US market, specifically for UL/ETL (NRTL) certification requirements. Our objective is to develop and optimize the complete electrical design, internal component layout, wiring and mechanical mounting arrangements of our 120–400 kW DC fast chargers to support successful UL/ETL certification in the United States. Scope of Work Electrical Design: Develop or revise electrical schematics, wiring diagrams, protection circuits and power distribution arrangements using EPLAN Electric P8. 3D Cabinet Design: Create or update detailed EPLAN Pro Panel 3D layouts showing exact component locations, dimensions and mounting arrangements. Power Components: Design placement and connections of MCCBs, contactors, DC fuses, busbars, power modules and protection devices. Control Components: Position controller PCBs, PLCs, communication modules, relays, power supplies and terminal blocks. Mechanical Layout: Optimize DIN rails, mounting plates, cable ducts, cooling systems, ventilation, cable routing and external connectors. UL Compliance: Review and optimize the design considering applicable US certification requirements, including UL 2202, UL 2231, UL 2251 and other applicable standards. Safety & Protection: Address electrical clearances, creepage distances, grounding/bonding, insulation, thermal management, component ratings and separation of AC/DC and control circuits. Manufacturing Documentation: Prepare detailed mounting drawings, drilling drawings, wiring schedules, terminal diagrams and BOM. Mandatory Experience Strong proficiency in EPLAN Electric P8 and EPLAN Pro Panel. Previous hands-on experience designing DC fast EV chargers for the US market. Practical involvement in UL/ETL certification projects for DC EV chargers, preferably UL 2202. Knowledge of US electrical safety requirements, UL-listed/recognized components, high-current DC systems and relevant NEC/NFPA requirements. Experience resolving design observations raised by UL, Intertek (ETL) or other NRTL certification bodies. Ability to work remotely using existing charger designs, photographs, component specifications and cabinet measurements. Resources Available We can provide existing electrical schematics, component lists, charger photographs, dimensional measurements and available CAD/EPLAN project files. Expected Deliverables Complete editable EPLAN Electric P8 and Pro Panel project files. Updated 3D cabinet assembly with accurate component placement. UL/ETL-oriented design review and compliance gap report. Detailed manufacturing and mounting drawings. Electrical wiring diagrams, terminal schedules and BOM. Recommendations for component changes required to support US certification. Acceptance Criteria The project will be considered complete when the agreed components are accurately represented, mechanical collision checks pass, the design matches verified cabinet dimensions, and all identified design issues affecting UL/ETL certification have been documented and addressed within the agreed scope. Final certification will remain subject to evaluation and testing by the applicable NRTL. Important – Before Applying Applicants must provide: Details of DC fast EV chargers previously designed, including power ratings. Specific experience with UL 2202 / ETL certification projects for the US market. Examples of previous EPLAN Pro Panel 3D cabinet designs. Details of any certification-related design modifications or NRTL observations successfully resolved. Estimated project cost and completion timeline. Preference will be given to engineers who have worked on DC fast chargers that successfully obtained UL/ETL certification in the United States. This assignment may lead to long-term engineering collaboration across our 120 kW, 240 kW, 300 kW, 360 kW and 400 kW charger models.
