In concept, Energybus is similar to the USB interface used on computers. Every USB-compliant device can be linked to any other via “Plug & Play”. What makes this possible is standardised specifications for the data and power connections, and also a unified connector standard.

EnergyBus is an open standard and purpose-made bus system for the electrical components in Light Electric Vehicles (LEVs) such as pedelecs, e-bikes, e-scooters, and also for energy management systems. It is based on the automotive CAN standard. The EneryBus protocol has been specifically designed to meet the requirements of light electric vehicles, and accordingly prioritises processing of system data, data packet transfer and on defining hardware such as connectors, cables etc. This means that manufacturers benefit from a standardised, closely defined developer toolkit. The standardisation allows all manufacturer of LEVs to use the same charging Infrastructure. Its communication IEC TS 61851-3-1/2/4/5/6/7 and connector systems IEC TS 62196-4 are published as IEC Technical specifications, which are referenced by EN Standards such as EN 50604-1:2016/A1:2021-07 and EN15194:2017+A1:2023.

The EnergyBus-M connector family which was first introduced in 2010 was sold by EnergyBus Member Rosenberger several million times in its Beta Version. The final IEC standardized version IEC TS 62196-4 Standrad Sheet 4-Ib available since 2012 is commercially in use since that time. The EnergyBus-NFC Connector Family which can be found in the IEC TS 62196-4 Standard Sheet 4-IIc has been introduced in 2015 as first prototypes and became commercially available in 2025 after several years of pilot series and trials.
