Currently, most of the commercially available hybrid transit city buses have a series hybrid powertrain topology. The series topology is probably the easiest solution to hybridize a city bus (Ehsani et al., 2010).This is because all the traction power is produced only by an electric motor or by several electric motors and the engine-generator (gen
