Xiaomi EV: Innovations Driving Energy Density and Efficiency

Xiaomi’s achievement in energy density and efficiency is attributed to several groundbreaking innovations:

Special Silicon Steel Sheet: The development of the industry’s highest strength special silicon steel sheet has been instrumental. Using a 0.2mm ultra-thin silicon steel sheet in the stator and a 0.35mm thin ultra-high-strength silicon steel sheet in the rotor reduces eddy-current losses at high frequencies, enhancing motor efficiency.

Hairpin Flat Wire Winding: The eight-layer hairpin flat wire winding in the stator, with a slot fill factor of up to 77%, allows for a smaller stator and generates a stronger magnetic field.Additionally, The rectangular shape of the hairpins, exceeding the conventional 45-50% fill factor, enables higher current capacity, improving efficiency and reducing heat generation.

Reduced Air Gap Limit: Xiaomi has successfully reduced the stator and rotor air gap limit to 1.3mm, minimizing the magnetic path reluctance originating from the air gap. A narrower air gap enhances the magnetic circuit, contributing to increased motor efficiency.

Patented Oil Cooling: The HyperEngine V8s incorporates patented oil cooling technology, enhancing heat dissipation and ensuring optimal temperature management. This not only improves efficiency but also enhances the reliability and lifespan of the motor.

AI Simulation Technology: Xiaomi leveraged AI simulation technology to optimize the design and performance of these electric motors, ensuring a holistic approach to efficiency and reliability.
