Xiaomi, the well-known consumer electronics manufacturer, recently held the EV Technology Launch, a conference in which he presented his five key technologies for his first car: electric drive, battery, die-cast manufacturing, intelligent cabin and intelligent driving. Among these, one of the most impressive was the presentation of its super-powerful, named engines Xiaomi HyperEngine V6s e V8s.
Xiaomi HyperEngine V6s and V8s: what we know about the brand's new engines
Xiaomi HyperEngine motors have been designed to bring high performance, energy efficiency and reliability to electric vehicles. These are permanent magnet synchronous motors, which exploit electromagnetic force to transform electrical energy into mechanical energy. Unlike internal combustion engines, electric motors do not need fuel, spark plugs, filters or lubricants, making them more environmentally friendly, quiet and less subject to wear.
Xiaomi has developed two types of HyperEngine engines: the V6s and the V8s. The V6s is the result of the collaboration between Xiaomi and Huichuan Technology, a company specializing in the production of electric motors. The V6s has a maximum power of 340kW a maximum torque of 510N·m and one maximum speed of 21.600 rpm. The V6s is suitable for medium-sized vehicles, such as SUVs and sedans.
Il V8s, on the other hand, is the first engine completely developed and produced by Xiaomi independently. The V8s is the most powerful and advanced engine in the HyperEngine range, with a maximum power of 425kW, a maximum torque of 635N·m and maximum speed of 27.200 rpm. The V8s challenges the global limit of engine speed and reaches the power density of 10,14kW/kg. The V8s is suitable for higher performance vehicles, such as coupes and sports cars.
Furthermore, to solve the problem of motor cooling, Xiaomi has redesigned the heat dissipation system and adopted a two-dimensional and three-dimensional oil cooling technology, which increased theheat dissipation efficiency of more than 50% and decreased the maximum temperature by 30°C. Furthermore, the stator and rotor have been completely redesigned, and the whole system is equipped with a self-developed SiC electronic control module, with a conversion efficiency of up to 99,85%.
Xiaomi HyperEngine V8s reportedly requested 155 patents throughout the entire research and development process, and has authorized 60 of them. The Xiaomi HyperEngines are intended to be mounted on Xiaomi electric vehicles, which are expected to be launched on the market by 2024.
