| Résumé : |
The transformation from the combustion to the electric engine entails several imponderabilities for the plastics industry. In part, electric drives have completely different material requirements which are becoming specifically evident with the increasing use of appropriate vehicles. The following article presents an overview of the most important changes. |
| Note de contenu : |
- Flame protection is required
- ID.2 reaches USD 100 per kWh
- Without halogens, phosphar and halides
- Reasons for electric breakdown
- Figure : In electric vehicles, the change in engine technology also entails new requirements for the plastic materials used
- Fig. 1 : Key components of the high voltage drive train system of a Chevrolet Bolt
- Fig. 2 : PA is a very suitable material also for EV applications. For instance, PA6 and PA66 are used in HV connectors, HV PA 4T busbars and contactors
- Fig. 3 : Terminal corrosion caused by outgassed heat stabilizers of migration of other ionic impurities in the plastic
- Fig. 4 : In order to increase the the voltage rather than the current
- Fig. 5 : The creep distance is often deliberately increased to prevent the flow of current between two contacts
- Fig. 6 : Comparison of different polymer classes by tracking resistance. Colors indicate respective mechanical strength
- Fig. 7 : Electric breakdown strength before aging at-elevated temperatures. Most polymers show a decline in breakdown strentgh at rising temperatures
- Fig. 8 : Electric breakdown strength after aging at elevated temperatures. The curves of the materials are similar before and after aging. As a result of aging, the dielectric strength decreases as expected
- Fig. 9 : DSM high-voltage material portfolio for high operating temperatures. Different materials are recommended depending on the temperature range
- Fig. 10 : Functional diagram of the powertrain in a battery electric vehicle. Electrification adds further components
- Table 1 DSM portfolio of compounds without critical halide salts or red phosphorous, which could lead to electro corrosion |
