EnergyBus defines the key interfaces

- within the vehicle, and to the charging infrastructure



EnergyBus is based around a number of standards relevant to manufacturers and suppliers of LEVs and components. The international standard IEC TS 61851-3 sets out the requirements for charging interfaces for vehicle and component manufacturers, and this allows them to ensure that their products can access public charging infrastructure. In the future it should be possible to charge any LEV battery, anywhere. 

For batteries, the standard EN 50604-1 applies at the European level.


The master plug

EnergyBus has condensed the wide variety of existing charging systems into a single plug family, delivering a functional, safety-certifiable charging standard for the LEV sector. Three variations of the plug are specifically designed to meet the requirements of different vehicle types, and are based around the IEC DIN 62196-4 standard:


Lock plug: electronic theft protection with no charging function


Charge-lock plug: 60V with electronic theft protection


Charge-lock plug: 120V with electronic theft protection


Charging socket for all plug types


The licensing model

The EnergyBus technology (protocol and plug geometry) is licensed by EnergyBus Operations GmbH. New products are tested by EnergyBus GmbH and issued with a unique identification number (EnergyBus ID). Products which pass the EnergyBus conformity test pay a small license fee to EnergyBus Operations GmbH. Products which have been tested are identifiable via their EnergyBus ID, and are compatible with the EnergyBus system.



This standardisation of the interface enables components, vehicles and infrastructure to form an interchangeable, open system. Components can be used in a variety of different vehicles, reducing their costs through economies of scale. More efficient system integration is made possible by the predefined interfaces – shortening development times and reducing development costs.



Individual components, system parts or software applications can be easily exchanged or added. Such flexible and swappable product ranges and systems are not only more environmentally friendly, they also deliver long-term planning security for decision-makers and manufacturers.
