In December 2015, the electric motor assisted Gree Group in providing a dedicated motor for its intelligent car wash machine (which does not require any cleaning, only requires 8 liters of water, saves 90% water, and washes a car well) with high temperature resistance (ambient temperature of 150 degrees Celsius), low temperature resistance (minus 40 degrees Celsius), environmental humidity of 90% rRH, and a service life of at least 5 years. After two years of joint research and development by nearly 50 engineers, it was successful in 2017. On February 2, 2019, which coincided with the 28th day of the twelfth lunar month, Ms. Dong personally held a new product launch event for the Gree intelligent car wash machine. The machine was successfully launched in bulk.
