Electromobility: Standards, Technical and Legal Information

Change to Electromobility and Autonomous Driving

The switch from combustion engines to electric drives and autonomous driving require new components. This has also changed the requirements for cables.

New laws and norms were necessary to regulate and standardize new forms of mobility.

Drive technologies for electric vehicles

Battery-electric vehicles ⇒ Power source: lithium battery (lithium-ion battery)

  • Electrical energy is converted into mechanical energy without CO2 emissions. Electrical energy, chemically stored in the battery, is made available to the electric motor. High-voltage battery mainly for the engine, low-voltage battery for smaller consumers, such as on-board electronics, radio, lighting; power supply for the components is regulated via the battery management system (BMS); use of high-voltage cables (such as LEONI Hivocar®)
  • Charging of the batteries via charging stations, various charging types (AC, DC) up to high power charging with special cables (HPC); charger for AC charging inside the vehicle (on-board charging), for DC charging in the station; charging port is the interface between the battery and the power source; special charging infrastructure required

Fuel cell vehicles ⇒ Power source: fuel cell, hydrogen technology

  • In the fuel cell, electrical energy is released from hydrogen and oxygen in a chemical reaction. The electricity is either converted directly into motion in the electric motor or temporarily stored in a battery.
  • Refuelling at hydrogen filling stations, which can basically be integrated into existing filling stations (e.g. H2 Mobility GmbH & Co. KG)

Hybrid vehicles ⇒ power source: combustion and electric motor connected by control unit

  • Full hybrid: can drive with either of the two drive types

    • Two-mode hybrid system: works like a continuously variable transmission

    • First mode: for low speeds and high loads. Combined operation (electric combustion engine) as well as purely battery-powered driving possible. During stop-and-go traffic, the internal combustion engine stays off

    • Second mode: for cross-country trips

  • Plug-in hybrid (also socket hybrid): The battery can be charged both via the internal combustion engine and on the power grid
