◉    Service Background

The battery pack, which charges, stores and supplies energy for electric vehicles, is animportant component which must meet the requirements of various electromagnetic environments.

The necessary test requirements are as below:

• CISPR 25 Conducted emissions Voltage method,Current probe method
• CISPR 25 Radiated emissions
• ISO 11452-4 Bulk current injection (BCI)
• ISO 11452-2 Absorber-lined shielded enclosure (RI Immunity)
• ISO 7637
• Magnetic Field emissions
• Magnetic Field Immunity
• ESD
• EFT Immunity
• Surge

◉    Test Site Introduction

In 2017, CTI Electronic Technology Division established an Automotive Electronic Components Testing Laboratory in Ningbo. Then in 2019, expanded its scale in another more comprehensive laboratory in Kunshan, which not only obtained CNAS accreditation in early 2020，but also incorporated an all-new design and materials to better provide a unique, high quality testing environment.

• Its U-shaped design allows for easy maneuver of forklifts and bulky samples, enhancing the turn-over rate of test items. Forklifts can enter the laboratories directly and is also very convenient for heavy samples such as new energy battery packs.
• Uses electric sliding doors and elevation platforms，flooring can withstand weight up to 2000kg/m²
• The floor is laid with highly corrosion-resistant and scratch-resistant hot-dip coated steel sheet with a coating layer of zinc, aluminum and magnesium (ZAM plates).
• Equipped with 1000V/400A and 1000V/200Apower distribution cabinets，which can be used to power new energy samples and loads during testing
• Uses imported high-quality ferrite and absorbing cotton with good fire resistance and not easily breakable or deformed.
• The temperature can be set directly to the circulating cooling water, convenient for heat dissipation for new energy samples and loads.
• Equipped with 3m*2.5m testing tables which can withstand up to 1000kg，convenient for testing larger new energy products.
• Handheld transmitter for immunity tests has a variety of single-point testing antennas which can also be used for testing on single frequency points.
• Testing Fixtures are safe, reliable and highly sensitive, customized antenna clip is convenient to operate, move and store.
• The control room has a high-definition display which can monitor the dark chambers，and is installed with high-definition cameras and a voice interaction system, allowing clients to communicate directly with the engineers during debugging and modifications based on real-time data.

CTI Automotive Electronic Components Testing Laboratory provides testing services in traditional automobile parts, new energy automobile parts, and railway. In addition, it also provides clients an all-new testing environment with comprehensive technical support and high-quality service to accelerate the marketing of their products at a perfect time.
