E-technology is the key to maintaining our mobility.
The drive train of e-vehicles is designed comple- tely differently compared to vehicles with internal combustion engines. Battery systems and electric motors are main components here, but com- ponents such as power electronics, alternator, cooler and possibly transmission also play a decisive role.
Only lithium ion batteries are currently installed in e-vehicles. They are impressive on account of their long life cycle and a large energy density. Thousands of lithium ion cells are concentrated in a battery block.
The electric motor as drive element plays a cen- tral role, although the term ‘electric motor’ is not quite correct, as the drive element can also be used as a generator and is also used accordingly in the recuperation.
The power electronics control the change in voltage in driving mode and charging mode. In this case, the electronics convert the electrical energy into the voltage level and waveform necessary for each consumer. A key feature is the high-voltage vehicle electrical system via which all components are connected to one another.
