Stamping Parts for EV Charger Enclosures

Stamping parts are indispensable for manufacturing enclosures of electric vehicle (EV) chargers—both residential Level 2 chargers and public DC fast chargers—providing the weather resistance, impact protection, and electrical safety required for outdoor and semi-outdoor use. EV charger enclosures must shield internal electrical components (circuit boards, cables, connectors) from rain, snow, dust, UV rays, and potential impacts (e.g., from vehicles or vandalism), while also meeting strict safety standards (IP65/IP67 ratings for water/dust resistance). Stamping parts, produced from materials like stainless steel (for corrosion resistance) or galvanized steel (for cost-effectiveness), excel in these high-demand applications.

The stamping process creates key enclosure components: main casing bodies (with sealed edges to prevent water ingress), front access doors (with gasketed seals and secure latches), and mounting brackets (for attaching chargers to walls or poles). For example, stamped stainless steel casing bodies feature a one-piece design (via deep drawing, a stamping technique) that minimizes seams—reducing points of water entry, while the surface is polished to resist fingerprint smudges and ease cleaning. Stamped galvanized steel mounting brackets have reinforced holes for secure installation, ensuring the charger remains stable even in high winds. Stamping also enables the creation of vent holes (with protective grilles) to allow heat dissipation from internal components, preventing overheating during long charging sessions.

Electrical safety is a top priority: stamping parts are designed with precise clearances between metal components and internal wiring, complying with IEC and UL standards to prevent short circuits. Additionally, the durability of stamped enclosures ensures chargers have a long service life (10+ years) in outdoor environments, reducing maintenance costs for charging network operators. Whether used in a home’s garage (Level 2 charger) or a highway rest stop (DC fast charger), stamping parts for EV charger enclosures deliver the protection, safety, and longevity needed to support the growing EV infrastructure.
