Electric Vehicle Chassis Design: Core Technologies and Development Trends
With growing environmental awareness, the electric vehicle (EV) industry is rapidly evolving. Unlike traditional internal combustion engine vehicles, EVs utilize clean energy sources such as electricity, with their core powertrain composed of the "three-electric systems" (battery, motor, and electronic control). Chassis design directly impacts vehicle safety and range performance.
As a critical structural component supporting key components, the chassis must prioritize battery safety.
- Adoption of lightweight materials (e.g., TRIP steel) to reduce energy consumption;
- Optimized battery placement (mostly under the chassis) to balance space and safety;
- A significant trend toward integration, where skateboard chassis integrates drive, control, and battery systems into a standalone module, enhancing design flexibility.
- Structural breakthroughs: Aluminum skateboard chassis enables decoupled body-chassis development, enhancing handling and maintenance convenience;
- Material upgrades: High-strength materials like TRIP steel reduce fuel consumption and emissions;
- Layout optimization: Hub motors reduce transmission losses, while gearless designs improve space utilization. Companies such as Tesla and BYD have achieved economies of scale through flat battery packs and unified architectures, though startups still face high-cost challenges.
- Optimizing power transmission paths while maintaining the basic structure of traditional chassis;
- Rationalizing the spatial layout of battery packs;
- Enhancing system stability through mechatronic integration.
With technological breakthroughs in solid-state batteries and other areas, electric chassis will further evolve toward intelligence and integration, becoming the critical foundation defining EV performance.
