Description

technical field [0001] The invention relates to the technical field of vehicle off-line detection, in particular to a 48V light hybrid vehicle off-line detection system and method. Background technique [0002] With the development of the automobile industry, the number of automobiles continues to increase. The automobile industry is facing challenges in many aspects such as energy and the environment. With the increasingly stringent regulations on emissions and fuel consumption, all passenger car companies must meet the average fuel consumption of 5L by 2020. All domestic OEMs are actively looking for solutions to meet the requirements of / 100km. Simply improving the fuel efficiency of the engine is basically difficult to meet these standards. Vehicle hybridization and pure electrification are the best technical routes. [0003] In 2011, Audi, BMW, Daimler, Porsche, and Volkswagen jointly launched a 48V system to meet the growing demand for vehicle loads, and also to meet t...
