The "Heart" of New Energy Vehicles, Dilong DCDC Converter
Jul 22,2024 | Dilong Charger
In the onboard power system of new energy vehicles, the DC/DC converter is responsible for converting the vehicle's DC power into DC power of different voltage levels to meet the power needs of various onboard devices.
Unlike traditional fuel vehicles, electric vehicles have two types of batteries: high-voltage power batteries and low-voltage batteries. The power battery is the core driving force of the vehicle, charged through an external power source, and stores high-voltage direct current. It cannot be directly used by low-voltage systems such as vehicle lighting, entertainment, and meters. Therefore, a DC/DC converter is required to convert high-voltage direct current into 12V, 24V, or 48V low-voltage direct current to provide electrical energy for the vehicle's low-voltage system.
Based on more than 20 years of R&D and production experience of the Dilong Group, as well as multiple advanced technologies, the Dilong onboard DC/DC converter has achieved small size, high efficiency, excellent electromagnetic compatibility and heat dissipation performance, making it an ideal choice for new energy vehicle power systems.
The Dilong onboard DC/DC converter has multiple power models to meet the needs of different vehicle models for products of different power levels. With lightweight design, high conversion efficiency, high stability, and comprehensive safety protection features, it provides a stable, reliable, and efficient solution for the power supply system of new energy vehicles.
Dilong onboard DC/DC converter has the following core functional advantages: Wide voltage input range: It has a wide voltage input adaptability and can operate stably in different power supply environments; High conversion efficiency: reduces energy loss, extends the service life of the vehicle power system, and improves energy efficiency; Small size&lightweight: Adopting lightweight design to improve energy efficiency, easy installation and layout; All digital control: achieve precise control and efficient operation, improve system response speed and stability; Shielding and anti-interference capability: Ensure stable operation of the system in complex electromagnetic environments; Electromagnetic compatibility: Reduce interference with other electronic devices and ensure the overall coordinated operation of the system; Support CAN communication: capable of data exchange and collaborative work with other onboard electronic devices; High reliability: equipped with comprehensive protection mechanisms and fault self recovery functions, safe and stable.
The key indicators and characteristics of EV onboard DC/DC converters, such as conversion efficiency, power level, volume and weight, electrical safety performance, heat dissipation performance, electromagnetic compatibility, and reliability, not only directly determine the performance of the product itself, but also relate to the stability and reliability of the vehicle power system.
