Lectron reveals automated manufacturing for EV charging gear

Lectron has opened its doors to reveal the sophisticated manufacturing processes behind the industry's most common electric vehicle accessories. As automakers transition toward NACS standards, the company produces a significant portion of the adapters and home charging units used by consumers today. A recent factory tour in southeast China showcased how automotive-grade quality control, including automated torque monitoring and rigorous environmental stress testing, ensures these components meet strict safety requirements for daily use.

According to Caranddriver, Lectron has provided a rare look into the industrial production of its electric vehicle charging equipment. While many consumers view adapters as simple cables, the company serves as a primary supplier for the vast majority of NACS and SAE conversion tools currently entering the market.

Automated assembly and component integration

The manufacturing process relies heavily on high-speed automation to ensure consistency across thousands of units. One of the most critical stages involves the production of printed circuit boards (PCBs), where specialized machinery affixes essential electrical components such as capacitors, resistors, and diodes in a matter of seconds.

This level of precision is required because Lectron must satisfy the rigorous vetting processes of multiple global automakers. CEO Christopher Maiwald noted that constant scrutiny from automotive engineers has forced the company to elevate its standards across all product lines, including their home charging hardware.

Automotive-grade quality control measures

The production line for the Nexus Level 2 home charger mirrors the assembly techniques found in traditional vehicle manufacturing plants. Key features of this process include:

  • Automated torque wrenches that tighten every fastener to a preset value, with data logged against each unit's unique serial number.
  • High-pressure air leak tests to verify waterproof integrity and ensure an IP67 rating for dust and water resistance.
  • Periodic validation testing where units are subjected to extreme heat, freezing temperatures, and physical impacts like being run over by a vehicle tire.
  • Durability is a core focus for the brand, with mechanical relays designed to last 30,000 cycles. The charging handles themselves are engineered to withstand 10,000 plug-in events, which equates to over 27 years of daily use. By utilizing these industrial methods, Lectron aims to provide hardware that can survive the demanding environments of home and public charging infrastructure.
