Silicon carbide has a wide range of applications in the field of new energy vehicles, and the following are its main application areas:

Motor controllers

Improved efficiency: The high electron mobility and low on-resistance characteristics of silicon carbide devices allow them to operate at higher frequencies, significantly reducing switching losses, thereby improving the efficiency of motor controllers. For example, under the same power output, motor controllers using silicon carbide devices can achieve an efficiency increase of about 5%-10% compared to traditional silicon-based devices, which means that new energy vehicles can travel longer distances on the same battery charge.

Reduced size: Due to the higher power density of silicon carbide devices, which can withstand higher currents and voltages, smaller silicon carbide chips can be used in the design of motor controllers to achieve the same power output, effectively reducing the size and weight of the motor controller, saving more space for new energy vehicles, and contributing to lightweight vehicle design, enhancing vehicle performance and energy efficiency.
On-board chargers and charging piles

Achieving fast charging: Silicon carbide devices can withstand high voltages and high currents, and have low conduction losses and high switching frequency characteristics, making them very suitable for use in on-board chargers and charging piles. During the fast charging process, silicon carbide devices can quickly transfer electrical energy from the grid to the vehicle's battery, achieving high-efficiency energy conversion, thereby significantly shortening charging time. For example, on-board chargers and charging piles using silicon carbide devices can significantly increase charging power, supporting higher charging currents and voltages, greatly reducing the charging time for new energy vehicles and improving user convenience.

Increased power density and reliability: The high thermal conductivity of silicon carbide helps with heat dissipation, allowing chargers and charging piles to maintain lower temperatures during high-power operation, improving system stability and reliability, and extending the lifespan of the equipment. At the same time, its high power density characteristics also allow chargers and charging piles to be smaller and lighter, making them easier to install and use, especially suitable for space-limited locations, such as public charging piles in urban areas.
Power control units

Optimized energy management: Silicon carbide devices used in the power control units of new energy vehicles can achieve more efficient and precise energy management. They can quickly control the energy flow between the battery and the motor, adjusting the motor's power output in real-time according to the vehicle's driving status and the driver's needs, thereby improving the overall energy utilization and working efficiency of the vehicle, further enhancing the range and performance of new energy vehicles.

Enhanced system stability: The high-temperature stability and high-frequency operating capability of silicon carbide devices allow them to operate stably in power control units, reducing performance fluctuations caused by temperature changes and high-frequency switching, enhancing the overall stability and reliability of the system, ensuring that new energy vehicles can operate normally under various complex conditions.
Regenerative braking systems

Improved recovery efficiency: During the regenerative braking process, silicon carbide devices can quickly convert the mechanical energy generated during braking into electrical energy and efficiently store it back in the battery. Their high conversion efficiency and fast response characteristics can maximize the recovery of braking energy, improving the energy reuse efficiency, thereby further enhancing the energy utilization efficiency and range of new energy vehicles.
Automotive lighting

High brightness and high efficiency: Silicon carbide-based LED lighting systems have higher luminous efficacy and better thermal management capabilities. Compared to traditional silicon-based LEDs, they can emit brighter light while consuming less energy, improving the energy efficiency and lifespan of automotive lighting systems, providing brighter and clearer lighting effects for new energy vehicles, which helps enhance driving safety.
Sensors and actuators

Enhanced reliability: Automotive sensors and actuators often need to operate under harsh environmental conditions, such as high temperatures, high pressures, and high humidity. The high voltage resistance and high-temperature stability of silicon carbide materials enable them to operate stably under these harsh conditions, improving the reliability and accuracy of sensors and actuators, ensuring that various control systems in vehicles can accurately perceive and respond to external information, ensuring safe driving and normal operation of the vehicle.
