Overview

The energy management manages the provision (supply) and consumption (budget) of electrical energy. It controls all the measures that assure the mobility of the vehicle and guarantee that all the consumers receive a stable supply of electrical energy according to requirements. The aim is efficient use of energy.

Versions of on-board electrical system:

12 V on-board electrical system

The 12 V on-board electrical system supplies the electrical consumers of different systems, such as  interior lighting, exterior lighting or engine management, with electrical energy. The main components of the 12 V on-board electrical system are the 12 V on-board electrical system battery, the alternator (vehicles with 12 V alternator) or the DC/DC converter (vehicles with 48 V technology, hybrid vehicles, electric vehicles) and the energy management control system.

48 V on-board electrical system (vehicles with 48 V technology)

The 48 V on-board electrical system supplies all 48 V consumer (consumers with high energy requirement) with electrical energy. It also provides electrical energy for starting the combustion engine with the starter-alternator. The main components of the 48 V on-board electrical system are the 48 V battery, the DC/DC converter (energy transfer), the powertrain control unit (traction management control) and the starter-alternator.

High-voltage on-board electrical system (hybrid vehicles, electric vehicles)

The high-voltage on-board electrical system makes it possible to operate the electric machine for the electric drive. The high-voltage on-board electrical system provides electrical energy to electrical consumers with high energy demands, e.g.  the electrical refrigerant compressor or high-voltage PTC heater. The main components of the high-voltage on-board electrical system are the high-voltage battery, the DC/DC converter (energy transfer), the electric machine and the battery management system control unit (energy management).
