Hardware quality engineering
EMVcon Inc. ensures hardware design and manufacturing quality, ensuring that engineering and manufacturing processes are performed correctly using adequately designed equipment, materials, and processes. The hardware quality engineering (HQE) team works closely with the design team, mechanical, electrical/electronics, and software, as well as the quality assurance team. The HQE team not only makes corrections in the tools, materials, and processes but actively mimics the design. The HEQ team seamlessly collaborates with the factory automation team to develop the right equipment to ensure manufacturing quality.
Software quality engineering
In accordance with the HQE, automotive battery pack systems are highly dependent on the BMS software quality to maximize the cell lifetime and ensure safety. BMS software quality can never be compromised at the cost of design and validation. EMVcon Inc. software quality engineering team develops versatile in-house software platforms and tools that ensure both performance and reliability of the software. EMVcon Inc.'s SQE team completely understands hardware design from chips to systems.
Factory automation engineering
EMVcon Inc. builds the most important manufacturing equipment in-house. This maximizes the manufacturing quality as well as minimizes cost overhead to penetrate new and emerging markets.
