In the competitive race of new energy vehicle technology, the electric drive system remains a crucial battlefield determining overall vehicle performance. As a leading enterprise in the new energy sector, VREMT's SiC electric drive technology has long been recognized by the industry. Its self-developed SiC four-motor distributed drive system has redefined the technological limits of quad-motor electric drives.
Traditional silicon-based IGBT devices have become inadequate in the new energy vehicle field, whereas VREMT's motor controllers utilize silicon carbide (SiC) materials, known for their excellent thermal conductivity and low loss characteristics, as the "secret weapon" for electric drive upgrades. This SiC electric drive not only enhances the vehicle's range but also improves the efficiency, stability, and safety of the electric drive system. The application of SiC technology allows the motor controller to operate stably in high-temperature and high-voltage environments, providing users with more powerful power output and a smoother driving experience.
In VREMT's SiC quad-motor electric drive system, dual motor control integration technology, through innovative designs like common bus capacitors, shared housing, and common filters, reduces the controller volume by 20% and boosts power density to 47.3kW/L. This deep integration not only frees up more space in the vehicle but also achieves high-precision calibration of dual motor dynamic torque, delivering silky smooth power response.
Unlike conventional single or dual motor layouts, VREMT's quad-motor electric drive system is a "power magician." Through a dual-sampling dual-update motor control strategy, VREMT can perform two samplings within one control cycle, quickly responding to motor state changes and reducing torque fluctuations. Additionally, the application of flux estimation technology optimizes the motor's magnetic circuit design, reducing magnetic saturation and losses, further enhancing system stability.
While pursuing extreme performance, VREMT has built multiple safety barriers for the electric drive SiC electric drive system. In terms of electromagnetic compatibility (EMC), VREMT has effectively reduced electromagnetic interference through low stray inductance optimization design and multi-layer EMC protection technology, enhancing the system's overall performance and reliability. The powerful redundancy processing capability of the multi-core main control chip can monitor the SiC electric drive system status in real-time, detect and identify potential faults, ensuring functional and information safety of the system. These intelligent protection measures provide users with a safer travel experience.
It is well known that high-performance batteries are the energy source for electric drive systems, converting stored electrical energy into mechanical energy, jointly determining the power performance and range of electric vehicles. VREMT's high-performance batteries, with their outstanding energy and power density, provide strong power support for the electric drive system. From SiC electric drive to quad-motor electric drive collaborative control, VREMT uses cutting-edge technology to interpret the evolution direction of new energy vehicles. The deep integration of its high-performance batteries and electric drive systems not only enhances vehicle energy efficiency but also provides a stronger power base for intelligent driving.
In the future, VREMT will continue to lead with technological innovation, committed to the deep integration of the three-electric system and the entire vehicle system. Through a self-research and self-production strategy, it will promote the large-scale application of SiC electric drives, quad-motor electric drives, high-performance batteries, and EV batteries, bringing users a more efficient and safer driving experience. At the same time, VREMT will continue to copyright the development philosophy of innovation, pragmatism, and efficiency, continuously enhancing its technical level to contribute to building a green, low-carbon, and sustainable ecological environment.
