The Difference Between Dual-Motor and Single-Motor in New Energy Vehicles
1 Answers
The difference between dual-motor and single-motor in new energy vehicles lies in their efficiency. Here are the specific details: 1. Dual-motor drive: There are mainly three methods. The first involves two motors with the same power being combined to achieve a multiple increase in torque and power. The second method uses two motors working in separate zones, with one responsible for front-wheel drive and the other for rear-wheel drive. The third method employs two single motors with different power outputs, where one controls the vehicle's operation at high speeds and the other manages low-speed operations, thereby improving work efficiency. 2. Single-motor drive: In the design of a single-motor system, the selected motor power is often larger to account for the vehicle's need to handle uphill climbs and complex road conditions. However, in practical applications, the motor often operates at low speeds, resulting in lower efficiency and significant energy waste. Dual-motor systems do not face this issue, as they use motors with different power outputs for low and high speeds, greatly improving energy utilization efficiency. Compared to single-motor systems, dual-motor systems are more energy-efficient and environmentally friendly, and they also significantly enhance the vehicle's range.
