What are the three components integrated in new energy vehicles?
2 Answers
Motor, reducer, and motor controller. The following are the reliability technical requirements for the three-in-one system in new energy vehicles: 1. Requirement 1: Random vibration, maximum root mean square acceleration: 21.4m/s2, 10 hours per direction; 2. Requirement 2: Sine random vibration - sine (100Hz-440Hz), maximum acceleration: 50m/s2; Test frequency range: 10Hz to 100Hz, 33 hours per direction; 3. Requirement 3: Sine random vibration - random, maximum root mean square acceleration: 68.7m/s2, 33 hours per direction; 4. Requirement 4: All vibration tests must be completed under high/low temperature cycling conditions.
I'm quite curious about the three-in-one system in new energy vehicles, which essentially integrates three key components: the motor, motor controller, and gear reducer. This design makes the entire drive system more compact and lightweight. With reduced vehicle weight, energy consumption is lower, resulting in faster acceleration and quieter operation. From my experience in car enthusiasm, the three-in-one system isn't just a technical upgrade—it also lowers manufacturing and maintenance costs. Manufacturers save on materials, and it's more convenient for us owners when replacing parts. In traditional electric vehicles, these components are separate and prone to issues, but integration improves reliability and optimizes battery range. Of course, this trend is common in new brands like BYD or Tesla, and may incorporate more functions in the future to truly achieve high efficiency and energy savings. When I tinker with cars in my garage, I always enjoy dissecting such details, believing it makes a significant contribution to environmental protection.
