Mechanical Design of Energy Storage Modules & Cabinets
Design mechanical structure of supercapacitor modules including cell fixation, busbar insulation isolation, end plate/side plate selection, and fastening solutions.
Design indoor and outdoor cabinets, CBU (Capacitor backup unit) slide-in chassis, and standard rack-mounted energy storage cabinets, meeting ingress protection (e.g., IP20/IP54), cooling duct requirements, and mechanical load specifications.
Lead material selection for structural parts, mastering characteristics and application scenarios of common metals (galvanized steel, cold-rolled steel, aluminum alloy) and insulating materials (PC/ABS, PP).
Electrical-Structural Layout & Integration
High-voltage side: Structural layout, clearance and creepage distance design for main circuit busbars and high-voltage connectors, ensuring current-carrying capacity and electrical clearance comply with safety standards.
Low-voltage side: Routing and fixation planning for CMS (Capacitor Management System) boards, voltage/current/temperature sampling harnesses (FPC/wire harness), avoiding signal interference and abrasion.
Topology optimization: Plan high-voltage and low-voltage separation inside the cabinet, properly arrange main circuit, control/protection circuit, and communication circuit, resolve EMC shielding issues.
Thermal Management & Safety Design
Collaborate with thermal simulation engineer on air duct or liquid cooling plate structural design; optimize heat dissipation structure for high-rate charge/discharge characteristics of supercapacitor.
Implement preventive safety concepts: directional exhaust channels, and mechanical mounting interfaces for aerosol fire suppression systems.
Standards Compliance & Validation
Familiar with and apply national standards, IEC and UL standards structural safety design.
Lead prototype assembly and debugging, resolve structural interference, vibration, sealing failure issues during production and testing; output 2D/3D engineering drawings and BOM.
Requirements
Education: Bachelor's degree or above in Mechanical Design, Mechatronics, Materials Engineering or related fields.
Experience: 10+ years in energy storage, industrial power supply. Must have actual mass production project experience in supercapacitor or battery modules/cabinets and systems.
Software: Proficient in 2D and 3D modeling such as Autocad and Solidworks, and basic FEA (Finite Element Analysis).
Materials & Processes: Deep understanding of sheet metal fabrication, injection molding, and die-casting; familiar with withstand voltage and flame retardancy (UL94-V0) requirements for insulating materials.
Electrical knowledge: Able to read electrical schematics, clearly understand physical isolation requirements between main circuit current flow and control circuit signals. Capable of manually calculating creepage distance and electrical clearance.
Plus Items: Experience in AI server backup power units, high-power pulse power supply, or grid frequency regulation energy storage projects.
