Application Cases | To create green power, it turns out that RFID can also do such a situation!

Standing on the bustling and noisy road, more and more green license plates flashed in front of our eyes from time to time. Nowadays, whether overseas or in China, new energy vehicles have become the trend of the future, for manufacturers and players in this track, one of the keys to winning the future new energy vehicle market is the technology research and development of new energy core components, especially the electric drive system, one of the new energy three-electric systems.

3-in-1 integration

The motor drive system of new energy vehicles composed of motors, reducers and motor controllers can be called the "heart" of electric vehicles, providing them with "whole body" power, and under the control of the driver, the energy of the power battery pack is efficiently converted into the kinetic energy of the wheels to drive the electric vehicle to run, or the kinetic energy on the wheels is fed back to the power battery pack. It is not difficult to see that the overall quality and safety of the electric drive system determine the performance of the entire new energy vehicle.

A leading enterprise in China's new energy vehicle motor and transmission system, it has long been committed to the core technology innovation of new energy vehicles, and provides customers with complete electric drive system solutions in the two major markets of passenger cars and commercial vehicles: including high power density water-cooled motors, oil-cooled motor systems, electromechanical coupled hybrid powertrains, special transmissions for new energy vehicles, and reducer assemblies.

The company's products have been successfully used by the world's largest passenger car and commercial vehicle companies, as well as a large number of high-end innovation pioneers in the automotive industry. Now, the company has launched a 3-in-1 electric drive project at its North American plant, which has laid an important stone block for the development of its entire overseas market.

In fact, the current electric drive system is developing in the direction of integration, high efficiency, miniaturization, light weight and low cost. The North American plant has achieved a total mass of about 95 kg, which is reduced by nearly 10 percent. The motor speed of the system has been increased from 120 r/min to 1, 600 r/min. Through this deep integration of the system, the coaxiality error of the motor and the reducer is eliminated, the structural stiffness of the assembly is improved, and the vibration and noise are reduced. When the efficiency of the reducer is increased by 1%, the cost is reduced by 10% to 15%.

RFID, creating green power

Three-in-one integration means a perfect parts assembly process, especially for the power core of new energy vehicles, to meet the quality requirements of the assembly process, especially through the traceability of the overall product assembly to meet the compliance requirements of new energy vehicles, it is particularly important.

At the North American plant, based on the trust in Balluff's RFID product technology, engineering implementation team and service quality, the Balluff RFID series was selected to document the motor assembly process, ensure process control quality, respond to product recalls, achieve product information traceability and ensure compliance with specifications and standards.

With the RFID solution consisting of an all-in-one RFID read/write head, a four-in-one RFID processor, an RFID read/write head, and an RFID tag code from Balluff, the entire assembly process parameters are automatically recorded, identified and archived.

Since the process parameters reflect the information of the assembly process, that is, the process steps to produce the desired product. Through the recording and identification of process parameters by RFID, assembly process control and process data archiving can be carried out easily, efficiently and error-free, so as to detect problems in time and start statistical process control of rework and work-in-progress.

RFID systems, on the other hand, keep track of each component used in the final assembly process by adding an additional step to save the lineage data as if it were archiving process data. By merging all component data and process information, the entire manufacturing process of a part is documented for future recall in the event of recalls, compensation, and violations.

The Balluff integrated RFID read/write head installed at an inclined angle of 45° well meets the requirements of medium and long-distance reading and writing and fast reading and writing in the case of a large number of metal parts on site, and at the same time, it can also connect multiple read/write heads with Balluff one-to-four RFID processors, which greatly simplifies the system and saves customer costs.

In addition, from design and implementation to after-sales, Balluff provides a full range of customer values, such as detailed installation guidance, product use training, and excellent service team support. It seems that Balluff's RFID solutions have really achieved such a situation for the assembly and production of electric drive systems for new energy vehicles.
