As intelligent new energy vehicles become standard in the industry, the two-wheeled electric vehicle sector is also undergoing a profound technological revolution. High-end features such as voice interaction, automated driving assistance, intelligent navigation, and contactless unlocking are no longer exclusive to four-wheeled vehicles and are rapidly becoming commonplace in electric scooters. At industry exhibitions such as the South China International Electric Vehicle Show, models equipped with autonomous driving technology capable of handling complex road conditions have made their mark. Features such as Bluetooth unlocking, voice control, navigation projection, and assisted driving are becoming increasingly common in mass-produced models. The realization of these intelligent features relies heavily on the efficient, stable, and reliable power electronics core—power MOSFET devices.

 To precisely match the stringent demands for power devices in the intelligent upgrade of two-wheeled electric vehicles, VBsemi, a leading domestic power semiconductor manufacturer , has launched a series of high-performance, high-reliability, and low-power MOSFET products based on its profound technical accumulation. These products cover the entire application chain from core power systems to intelligent perception and interaction , providing a solid hardware foundation for the intelligent upgrade of two-wheeled electric vehicles.

 The demand for MOSFET upgrades in the intelligent core modules of two-wheeled electric vehicles

The explosive growth of intelligent functions has placed higher demands on power devices in the following key modules:

1. High-efficiency motor drive and power control: MOSFETs are required to have extremely low on-resistance (RDS(on)) to reduce losses, high switching speeds to enable precise PWM control (such as automatic speed regulation, hill assist, and energy recovery), and excellent heat dissipation capabilities to cope with continuous high-current operation.

2. Precision Battery Management System (BMS): MOSFETs are required to provide low-loss switching, precise current control, and high reliability in the charging and discharging paths, cell balancing , and other links to ensure battery safety (overcharge, over-discharge, short-circuit, and over-temperature protection) and maximize driving range.

3. Intelligent interaction and vehicle systems: DC-DC converters that power displays, voice modules, Bluetooth/WiFi modules, and various sensors (radar, cameras), require high-efficiency, low-noise, small-package MOSFETs, with a particular emphasis on low quiescent current to extend standby time.

4. Automated Driving Assistance Systems (ADAS): Radar, ultrasonic sensors, and control unit power supply and signal processing circuits require MOSFETs with high switching frequency, low Qg (gate charge), and excellent EMI performance to ensure fast sensor response and system stability.

5. Body control and comfort systems: Lighting control (such as automatic headlights), anti-theft locks, seat cushion sensing, keyless start, etc. require cost-effective, highly reliable, and easy-to-drive MOSFETs.
