Why should we pass AEC-Q100 certification?

Wireless charging is a new form of mobile phone charging in recent years. Many owners of fuel cars will also buy a wireless charging car charger placed in the car for mobile phone convenient charging, a put charge without hands to plug the line. New energy vehicles have the advantage of being a late mover, that is to say, most of the new cars have been installed in front of wireless charging, mobile phones can be charged in the corresponding charging position, without plugging operation.

For the front installation of new energy vehicles, wireless charging is a wireless charging solution provided by wireless charging scheme manufacturers. Not only does the wireless charging system need to meet Qi certification, but the chips it uses also need to meet stringent hardware standards. Since the life cycle of the vehicle is 10-15 years, the reliability of the front-mounted wireless charging products and wireless charging scheme manufacturers have very high requirements.

The chip introduction of NuVolta has passed the certification:

NuVolta has been certified by AEC-Q100 are two intelligent full-bridge chips NU8015Q and NU8040Q for wireless charging emission, supporting 15W and 40W wireless charging output. Compared with the scheme of driver plus independent MOS tube, Vooda integrated power stage not only has the advantage of high integration, but also needs to carry out AEC-Q100 and AEC-Q101 tests respectively in the scheme of driver matching MOS tube. Vooda intelligent full bridge also has the advantage in cost.

Both NU8015Q and NU8040Q are intelligent control chips for wireless charging transmitter, which are integrated with full-bridge MOS tube and driver circuits. NU8015Q supports up to 15W wireless charging output and 4V-21V power supply voltage range. NU8040Q supports 40W wireless charging output, 4V-21V supply voltage range, and ambient temperature range from -40 ° C to 105 ° C.

The picture shows NVTREF8040Q, a reference design for car wireless charging launched by NuVolta based on NU8040Q integrated power class chip, which supports 50W wireless charging power and has an efficiency of up to 78%.

Gauge Level Reliability Test Report

The vehicle gauge level device reliability test report of Voda NU8015Q/NU8040Q integrated power level chip was issued by VESP Techonology Corp.

Gauge certification takes months and requires various tests on thousands of samples. Only through the vehicle gauge level test verification, the world famous car factory may choose. Therefore, the wireless charging manufacturers that can pass the vehicle gauge level certification are not only strong in R&D strength, but also in the leading position of the reliability of the devices.

AEC-Q100, the industry's most representative vehicle gauge keyword, is a specification designated by the American Automotive Electronics Association AEC. It is mainly a set of stress test standards designed for integrated circuit products of on-board applications. This specification is very important for improving product reliability and quality assurance. AEC-Q100 is to prevent all kinds of conditions or potential failure state, to carry out strict quality and reliability confirmation for each chip, especially to carry out standard specification testing of product function and performance.

The AEC-Q100 is more stringent than consumer and industrial electronic certification.

AEC-Q100 certification includes accelerated environmental reliability verification, accelerated life simulation reliability verification, package reliability verification, chip and wafer process reliability verification, electrical parameter verification and defect screening inspection. With quantitative data as the basis of product quality, the experiment simulates the specific use environment and specific specification function of the product within a given time, calculates the probability of the product to complete the work target, and uses quantitative data as the basis of product quality.

New Energy Vehicle Market Opportunities

Citing data from the China Association of Automobile Manufacturers, from January to October 2021, a total of 2.566 million new energy vehicles were produced, and a total of 2.542 million were sold, each of which has at least one wireless charger or two. With the wireless charging function being standard on mobile phones, wireless charging support has also become a standard feature of new energy vehicles, while traditional fuel vehicles are also increasing wireless charging support.
