Hybrid electric vehicle working mode

Hybrid electric vehicles have two basic working modes, namely series, parallel and series-parallel (or hybrid). The shortcomings of hybrid power-driven vehicles are: there are two sets of power, plus two sets of power management and control systems, the structure is complex, the technology is more difficult, and the price is higher. Due to the promotion of the "New Generation Automotive Partnership" (P NGV) plan, the three major U.S. automobile companies have screened and compared hundreds of plans for various unit technologies and different organizations, and believe that the use of hybrid power is to achieve 100 kilometers of mid-level cars. Feasible solutions to increase fuel consumption have therefore received greater attention. After years of research, hybrid electric vehicles have developed some successful examples.
