Positioned as a B-class plug-in hybrid SUV, the Song Ultra DM-i is officially launched, featuring a smart cockpit, long range, spacious interior, and comfortable configurations.
BYD says this is the first Dynasty model equipped with the “DiDiXia” intelligent agent system. Unlike traditional passive voice assistants, the system is an AI agent with proactive interaction capabilities, offering personalized greetings, content recommendations, and voice interaction based on user habits. Users can complete tasks like finding restaurants, booking tickets, and streaming shows via natural language — even without remembering exact song or show names, fuzzy descriptions are enough to search. BYD says the system emphasizes “technology actively adapting to people,” lowering the barrier to smart features, and will be rolled out to select existing EV models via OTA updates.
In terms of range and efficiency, the new car features BYD’s 5th-generation DM technology, delivering a maximum CLTC pure electric range of 310 km and a combined range of up to 1,845 km. Depleted-battery fuel consumption is just 3.3L/100km, virtually eliminating range anxiety for long trips.
The powertrain pairs a 1.5L engine with an electric motor in a plug-in hybrid setup, producing 70 kW from the engine and 175 kW from the motor, balancing smooth driving with strong acceleration. The vehicle also features the YunNian-C intelligent damping body control system and TBC high-speed tire blowout stability system — both class-exclusive — maximizing ride quality and safety.
On configuration, the Song Ultra DM-i boasts 43 “class-leading” features, including a 16-speaker “Sky Sound” audio system and bed mode. Over 100 features come standard across all trims, with even the entry model offering 7 airbags, panoramic sunroof, electric sunshade, power tailgate, 19-inch wheels, 15.6-inch central touchscreen, power front seats, wireless charging, and a dashcam — strong value for money.
The lineup includes 5 variants: 310 km Excellence, 310 km Transcendence, 310 km Leadership, 205 km Transcendence, and 205 km Leadership. The 310 km Leadership trim, priced at 139,900 RMB, marks the first time a B-class plug-in hybrid SUV with 310 km pure electric range has entered the 130,000 RMB segment. The vehicle also supports an optional “God’s Eye B ADAS LiDAR Edition,” providing dual coverage for parking and urban navigation to meet advanced smart driving demands.
……………………………………………………Electrostatic Protection Knowledge……………………………………………………
Electrostatic discharge (ESD) and electrical surges are common transient high-voltage phenomena in automotive electrical systems. They are capable of damaging sensitive electronic components, triggering system failures, and even posing serious safety hazards. To address this, TVS (Transient Voltage Suppression) diodes and ESD (Electrostatic Discharge) protection components have been developed. As specially designed protection devices, their primary role is to safeguard automotive electronic equipment from such electrical shocks. TVS & ESD components, through their extremely fast response speed, clamp transient overvoltages to a safe level and divert the surge current to ground, thereby providing effective protection for downstream circuitry.
Within the automotive electronic architecture, TVS & ESD components are crucial for ensuring the stable operation of internal precision systems. As modern vehicles integrate a large number of control units and sensors that are highly sensitive to electrical interference, these components must be deployed at multiple critical nodes to build a comprehensive protection network. The protected systems cover all areas, from the powertrain to in-vehicle infotainment.
Specifically, TVS & ESD components in automobiles serve the following primary protective functions:
- Communication Bus Protection: Communication buses such as CAN, LIN, Automotive Ethernet, and RS232/485, which act as the vehicle’s “neural network,” are highly susceptible to interference from ESD and surges. TVS & ESD components ensure the integrity and stability of data transmission, preventing communication errors or interruptions.
- Core Safety System Protection: Core safety systems that are directly related to driving safety—such as the powertrain, Battery Management System (BMS), braking system, and radar—must rely on TVS & ESD components for protection to prevent critical functional failures caused by electrical interference.
- Interface and Peripheral Protection: External connection points like charging ports, keyless entry receivers, side-view cameras, and other cameras are primary pathways for ESD intrusion. TVS & ESD components can effectively block these paths, preventing damage to internal circuitry during connection events.
- Lighting and Display System Protection: In-vehicle display navigation and lighting systems also require protection to avoid damage such as burnt-out LEDs, display malfunctions, or permanent failure caused by transient high voltages.
In summary, TVS & ESD components play an indispensable role in ensuring the reliability of automotive electronic systems, reducing the total cost of ownership, and safeguarding the safety of drivers and passengers. As the level of automotive electronics and intelligence continues to increase, the proper deployment of these protection components has become a key element in enhancing overall vehicle quality and building user trust.
