Huawei's DE-i range extender generator technology is very similar to BYD's Xiaoyun generator technology. Do BYD and Huawei have any patent authorization or technology exchange on this range extender technology? If there is any technology exchange, what kind of exchange is it?

BYD: Hello! The Xiaoyun-plug-in hybrid 1.5L high-efficiency engine is specially designed for DM-i super hybrid technology. It is developed with the goal of achieving ultra-low fuel consumption, with a thermal efficiency of up to 43%, making it the world's most thermally efficient mass-produced gasoline engine. This engine is not only super fuel-efficient and easily meets the "National VI b" emission standards, but also provides smooth and quiet driving enjoyment with its excellent NVH performance. Behind the ultra-high thermal efficiency, it has an ultra-high compression ratio of 15.5, an increased stroke-bore ratio, an Atkinson cycle, an EGR exhaust gas recirculation system, a series of friction reduction measures, and an optimized engine control system for high thermal efficiency goals. Thank you for your attention to the company!
