China Youth Daily Client News (China Youth Daily, China Youth Network reporter Wang Jinghui) Today, as the new energy vehicle industry is booming, technological innovation has become a key force in promoting the industry's progress. Not long ago, BYD released the fifth-generation DM technology, marking another breakthrough in the field of plug-in hybrid vehicles.
From August 8th to 10th, BYD held a fifth-generation DM technology analysis meeting in Beijing. Senior engineers from BYD Automotive New Technology Research Institute comprehensively analyzed the technical innovations of the fifth-generation DM, which attracted a lot of attention.
"The fifth-generation DM technology has achieved a thermal efficiency of 46.06% for mass-produced engines. Under NEDC conditions, the fuel consumption per 100 kilometers is only 2.9L, and the comprehensive cruising range reaches 2,100 kilometers." BYD engineers told reporters that the reason why the fifth-generation DM technology has achieved such outstanding results is inseparable from the strong technical support behind it.
Specifically, the EHS electric hybrid system not only improves the power density through its ultimate structural design, but also significantly reduces the loss in the energy flow path, with an overall operating efficiency of up to 92%. The blade battery dedicated to plug-in hybrids has achieved a significant increase in energy density while ensuring safety, providing a solid guarantee for the vehicle's long cruising range.
The reporter learned that in addition to the electric-based power structure, another highlight of the fifth-generation DM technology is the full-temperature vehicle thermal management structure. This structure integrates the three major systems of front cabin thermal management, battery thermal management, and cabin thermal management into a whole, allowing the various systems to work together efficiently.
"In high temperature environments, this architecture can save up to 10% of energy consumption; in low temperature environments, it can save up to 8% of energy consumption. This comprehensive energy-saving design not only allows the vehicle to maintain optimal performance in different environments, but also greatly improves driving comfort." The above engineer told reporters.
At the event, BYD also conducted a test of the fuel consumption of Qin L DM-i and Haibao 06 DM-i per 100 kilometers. The final test results showed that the fuel consumption of both models was less than 2.7L per 100 kilometers, which once again confirmed the strength of the fifth-generation DM technology.
