Description
B60L covers the complete electrical propulsion systems for vehicles, including motor control, power distribution, and energy storage technologies for electric and hybrid vehicles. The subclass encompasses auxiliary power supply systems for non-propulsion functions, electrodynamic braking mechanisms applicable across all vehicle types, and magnetic suspension or levitation systems. It also includes monitoring and diagnostic systems for operating parameters of electrically-propelled vehicles and safety mechanisms specific to electrical vehicle systems. This classification excludes non-electrical propulsion systems (covered in other B60 subclasses) and general electrical safety devices not specific to vehicle applications.
