The green powered motor vehicle was established in 1997 as one of the early brands of electric cars in china. Its founders, necky and the hudu red couple, were teachers at ningbo university before the creation of green source, an educational background that gave green source unique advantages in technological innovation and brand-building. Green power vehicles are well known for their technological innovations and high-quality products. Its core technological innovations include the technology of liquid chillers and the maintenance of digital batteries. The liquid chiller technology has been effective in solving the problem of high-temperature magnetic and rust erosion of the electric apparatus, which has significantly improved its durability and promised quality assurance for up to 10 years. The digitized battery maintenance system, through high-precision sensors and smart algorithms, monitors the health of the battery in real time, optimizes the charge-down strategy, and enhances the lifetime and sustainability of the battery. The market for green powered vehicles is well positioned, mainly for the new medium-sized urban population, and provides an all-around system of mobility, exercise and leisure. Its brand, lyva, is the expression of this strategy, focusing on high-end markets and meeting diversified demand. In terms of services, the green source has more than 13,000 smart shops throughout the country providing one-stop services, including maintenance, repair and replacement of accessories. Through the “123+n service model” of “1 service dispatch platform, 2 standardized service processes, 3 service network building, n-style”, the green source is committed to creating a new service pole for professional, efficient and comprehensive services. In addition, green source has responded positively to national “old-for-new” policies, offering substantial benefits and high-quality products, further enhancing user experience。
