System Features
System Description
- The DC/DC converter is responsible for transforming the high voltage from the battery into low voltage. This facilitates the charging of the onboard battery while supplying a steady DC power source to low-voltage components.
- The DC/AC inverters convert the high-voltage battery’s direct current into three-phase alternating current. This conversion is essential for controlling vital vehicle systems such as the electric air compressor and power steering pump, ensuring the operation of air pressure and power steering functionalities.
- The PDU serves as a control hub for the vehicle’s power supply system. It manages tasks such as power distribution, current measurement, short circuit protection, charge and discharge control, pre-charging, manual emergency stop, and insulation detection.
- Integrated and lightweight design: this Auxiliary Inverter boasts a 4-in-1 integrated design, significantly reducing system weight and size. This approach not only offers a lightweight solution but also delivers substantial space, wiring, and cost savings for electric commercial vehicles.
- Versatile application: designed to excel across diverse work conditions, the Auxiliary Inverter operates flawlessly within a temperature range of -40°C to 60°C. With an IP67 rating, it proves suitable for electric commercial vehicles across various challenging environments.
- Quiet operation: engineered for minimal disruption, our Auxiliary Inverter operates at less than 42 dB, ensuring a tranquil driving experience for both drivers and passengers.
- Enhanced safety: rigorously tested for safety and reliability, our product has undergone a series of assessments including low temperature, high temperature, humidity, salt spray, vibration, mechanical strength, noise, insulation performance, and voltage withstand tests.
