The electric compressor controller drives the rotation of the scroll compressor motor to achieve the compression of refrigerant gas and refrigerant flow. This product is mainly used in new energy vehicles
The electric compressor controller improves refrigeration efficiency, control accuracy, reduces energy consumption and noise through the following characteristics:
The use of weak magnetic control technology effectively expands the maximum speed of the compressor, thereby significantly improving the overall refrigeration efficiency. This technology not only enhances refrigeration performance, but also improves the energy efficiency ratio of the entire machine.
By introducing harmonic injection algorithm, the system can effectively cancel out some noise during operation, achieving a quieter operating environment.
Low power and sleep mode: The system places special emphasis on energy efficiency, has the characteristic of low power consumption, and supports standby and sleep modes to further reduce energy consumption.
It is designed to adapt to various voltage platforms and different displacement requirements. In addition, through the design of integrated heaters, the dual functions of refrigeration and heating are achieved, increasing the flexibility and practicality of applications.
The solution is suitable for 400/800VDC voltage platforms and mainstream compressor displacements in the market, while it also compatible with SPM and IPM types of permanent magnet synchronous motors, covering a wide range of application needs.
In terms of hardware, the scheme adopts a high-voltage side single MCU combined with a split type IGBT, providing strong control capabilities for the system. On the software side, the FOC algorithm is used, supplemented by dead zone compensation and weak magnetic control strategies, to ensure precise control of the compressor and improve overall performance and reliability.
The controller adopts advanced AUTOSAR open system architecture, it provides high flexibility and scalability. This architecture supports seamless integration of various modules and applications, making it easy for the system to adapt to constantly changing technological requirements.
The controller provides OTA (Over The Air) technical support, allowing software updates to be made wirelessly. This not only improves maintenance efficiency, but also ensures that the system can receive the latest functional improvements and security updates in a timely manner.
The system supports Unified Diagnostic Services (UDS) and integrates application code. This feature enables the system to diagnose and troubleshoot more effectively, while facilitating application updates and management.
The system design follows the ISO 26262 ASIL B safety standard, ensuring high security performance. Compliance with this standard means that the system has reached industry-leading levels in reliability and safety.
The system supports LIN and CAN communication protocols, making communication with other in vehicle systems more efficient and reliable. This enhances the interoperability of the system and provides a foundation for more complex vehicle network integration.
The system design also includes the option of integrating a heater, which not only provides cooling function but also enables heating. This dual functional design greatly enhances the practicality and application range of the device.
