Bafang EMC Laboratory investment now up and running
After two years and a capital investment of more than ￥10 million (approximately €1.44 million), Bafang has successfully completed the building of an Electromagnetic Compatibility (EMC) laboratory in Suzhou, becoming one of the few companies in the global electric system industry to own such a facility.
Covering 120 square metres, the laboratory has both a Semi-Anechoic Chamber and an EM Shielding Chamber. The testing capabilities cover eBikes, civilian goods and components, and can fully meet the EMC testing requirements for motors, human-machine interfaces (HMIs), controllers, sensors, batteries, chargers and various other products.
The Bafang EMC laboratory will provide a large amount of test data support for future product projects and effectively achieve the key aims of “cost reduction, efficiency increase, and quality improvement”. The EMC Laboratory will also speed up overall project R&D progress and provide a solid foundation for R&D innovation.
The pricing reductions will come from costs related to EMC pre-compliance testing and components‘ CE certificating coming down.
In line with Bafang’s commitment to creating advanced laboratory facilities, in addition to the EMC laboratory, the Bafang Laboratory Centers also feature spaces dedicated to Environmental Reliability, Battery, Mechanical Reliability, Aging, Acoustics and more.
In explaining the investment and why it is a crucial piece of the eBike OEM’s puzzle, Bafang writes “Imagine that when you turn on a vacuum cleaner, the TV next to you becomes blurry. This phenomenon is called Electromagnetic Interference (EMI), occurring when a device conducts its voltage or current and influences other devices. In the process of product manufacturing, solving the EMI problem is a key task, and EMI interference will be exposed through EMC testing.
“An EMC laboratory can fully verify the immunity of a system‘s equipment in its electromagnetic environment, which could be also called electromagnetic sensitivity. In addition, an EMC lab can judge whether the system equipment causes EMI that is above a particular limit to other equipment.”
Based on the ISO17025 laboratory management standard, the Bafang EMC laboratory not only has comprehensive testing methods, but can also achieve mutual recognition of data with top laboratories in the world due to the advanced equipment within.
In the future, Bafang will strive to obtain laboratory qualifications accredited by the China National Accreditation Service for Conformity Assessment (CNAS), and continue to promote quality management to a new level.
