Problems solved by technology

However, this invention does not involve the energy optimization management strategy for fuel cell vehicles. Unlike engines, fuel cells cannot be frequently started and stopped during work, and have more stringent constraints. Compared with gasoline-electric hybrid vehicles, fuel cell vehicles Energy management design is more difficult

[0008] To sum up, although the currently published patents have involved some fuel cell vehicle energy management solutions, they are basically based on rule-based design methods, and it is difficult to obtain optimal fuel economy. Economical, the algorithm to be used has a large amount of calculation, and the complete working condition information needs to be known in advance, and it can only be calculated offline
