The Role of Oscillators in Modern Electric Vehicle Systems

The push towards electric vehicles (EVs) and autonomous driving technologies has stemmed from the progress in battery technology, enabling electric vehicles with the ability to improve fuel economy, lower fuel costs, and reduce emissions. As the electric vehicle industry continues to evolve, the need for reliable, high-performance frequency control products grows in tandem.

What Frequency Control Products are Suited for Electric Vehicles?

The integration of intelligent technologies and the widespread adoption of EVs has sparked a rising demand for advanced high-quality oscillators to meet the need for enhanced efficiency, durability, performance, and quality. A device that fulfills these requirements will earn an AEC-Q200 qualification. 

At Aker, we provide AEC-Q200 qualified crystal oscillators (XOs), making them key frequency control products to manage the sophisticated electrical systems that power EVs.  With the use of sensors to monitor voltage and current levels in battery packs, electric cars need highly accurate timing components to ensure efficient operation and reduce energy losses.

What Kind of Electric Vehicles are there? 

Crystal oscillators are used in many types of electrical vehicles including:

  • Energy Vehicles
  • Hybrid Energy Vehicles
  • Battery Electric Vehicles
  • Fuel Cell Electric Vehicles

 

What Key Features Do Oscillators Enable in Electric Vehicles?

  • Advanced Driver Assistance Systems (ADAS)XOs in ADAS technologies maintain stable clock frequencies to ensure accurate sensor data, enabling functions like speed measurement, obstacle detection, lane departure warnings, and adaptive cruise control.
  • Battery Management Systems (BMS): Oscillators ensure precise timing and synchronization in BMS, optimizing battery performance, safety, and lifespan while improving vehicle efficiency and range.
  • Electric Motor Control: In EVs, XOs provide precise timing for motor control, enabling accurate speed, torque, and power regulation for better performance and energy efficiency.
  • Charging Infrastructures: EV charging infrastructure includes AC slow charging (Levels 1 and 2) using on-board chargers (OBCs) and DC fast charging, which delivers higher power directly from the station. OBCs manage current and voltage based on battery data, while advanced bi-directional OBCs and traction inverters enhance efficiency by enabling energy recovery and grid interaction.
  • Navigation and Communication Systems: XOs ensure reliable GPS, telematics, V2V, and V2I communication by providing precise timing and signal synchronization for accurate navigation and connectivity.
