BYD officially launched the Denza Z9S, positioned as a “tech luxury intelligent sedan,” available in three trims: the Flash Charging Premium, Flash Charging Flagship, and Yi-San Flash Charging Performance. The vehicle features an original “Elegant Pose” design with a “meteorite” front face and rear tail, offered in seven exterior colors and three interior options. The cabin is equipped with dual zero-gravity seats, Nappa leather, and a luxurious wide rear armrest, highlighting a premium quality.

In terms of performance and range, the Denza Z9S is built on the e³ platform and equipped with the second-generation Blade Battery. It achieves a CLTC range of 1,100 km, breaking the record for mass-produced pure electric vehicles globally. Paired with flash charging technology, it claims to charge sufficiently in 5 minutes and fully in 9 minutes. The powertrain offers high and low output versions; the low-output version peaks at 320 kW, while the high-output version rises to 370 kW, delivering a combined horsepower of 1,210 Ps. The car accelerates from 0-100 km/h in just 2.68 seconds and debuts a “novice drift mode,” with performance claims surpassing million-dollar supercars.

Regarding chassis and safety, the Z9S features 10° split rear-wheel steering and the DiSus-A intelligent air body control system, supporting Road Preview 2.0 for a balance of agile handling and ride comfort. The body utilizes a high-strength hot-formed steel cage structure, with high-strength steel and aluminum alloy accounting for 91.1% of the composition. The torsional stiffness reaches 45,036 N·m/deg, meeting C-NCAP five-star standards.

Intelligent features include the standard God’s Eye 5.0 advanced driver assistance system (ADAS), featuring city navigation and intelligent parking. The interior debuts the “Diva” intelligent partner and a 15.6-inch smart ecosystem screen. It is the first globally to support Apple CarPicture-in-picture mode, seamlessly integrating all mainstream phone brands including Huawei, Apple, Xiaomi, and others for full-scenario phone-vehicle connectivity. Dimensions-wise, the low-power version measures 5,090×1,980×1,510 mm, while the high-power version stands at 5,090×1,980×1,490 mm, with both versions having a top speed of 250 km/h.

……………………………………………………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:

1. 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.
2. 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.
3. 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.
4. 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.
