3Ccar has 48 companions from 14 completely different nations engaged on ICs for EVs.
By 2030, 50% of newly registered automobiles shall be electrically powered, linked or automated.
This requires a brand new system strategy in car structure to assist electromobility and automated driving.
In 2014 standard vehicles have been already outfitted with between 70 and 100 linked ECUs, and this determine was attributable to rise pushed by rising calls for for environmental compatibility, effectivity, security and comfort.
The 3Ccar challenge had a finances of €54 million. It kicked off in 2015 and ran for 41 months.
The eleven German companions’ overriding purpose was to scale back complexity, whereas on the similar time enhancing the reliability of electrical and automatic automobiles.
To this finish, 3Ccar developed a brand new system strategy that reorganizes car structure into car domains.
These domains allow useful and task-oriented coordination. The reduces complexity regardless of rising necessities, considerably simplifying the event of autonomous electrical automobiles.
The person Engine Management Items (ECUs) are built-in into the respective domains, from the place functionalities akin to steering, brakes and drive are managed. This entails using a small variety of highly effective area controllers. These are based mostly on multi-core automotive processors, such because the AURIX™ microcontrollers already provided by Infineon. The standard powertrain, for instance, has a site of its personal. In addition to controlling complexity, the smaller variety of ECUs and the upper degree of integration additionally enhance robustness.
The good battery
So far, the appreciable quantity of cabling in automotive batteries has meant excessive prices and a low degree of reliability. Working along with the Fraunhofer Institutes IISB and IPA, 3Ccar developed a brand new, modular and versatile idea for future batteries for use in electrical and hybrid automobiles. The sensors and digital elements are built-in with the battery cell community as an alternative of at battery pack degree. This can be a utterly new strategy that simplifies battery administration and, additional down the road, may also provide the choice of manufacturing “Sensible Batteries Made in Europe” at a aggressive worth. The system has fewer particular person elements, making it much less liable to errors and therefore boosting the robustness of the car structure.
Security shut-off for gasoline cells
With assist from Infineon, Daimler, Fraunhofer IISB and Lange Aviation, 3Ccar developed a brand new security shut-off for discharging gasoline cells. In comparison with rival merchandise out there right this moment, this shut-off is extra compact and will be reused. Whereas current ideas can solely be used as soon as, since they’re destroyed by the activation course of, the brand new improvement can short-circuit the gasoline cells in a focused method and launch them once more a number of occasions over.
The drive motor
Along with Siemens, 3Ccar has developed an electrical drive that includes a better energy density than comparable merchandise. Its compact construction means excessive car efficiency is feasible even with difficult house constraints. As well as, the brand new drive motor can be extra environment friendly and dependable.
Routing for e-vehicles
The Amberg-Weiden College of Utilized Sciences developed particular vehicle-to-network communication (V2N) for electrical automobiles. The purpose was to develop a fundamental service that may take over the whole route planning course of. A server-based system for route planning in street networks was deployed and mixed with data on charging stations. This server-controlled routing system made it potential to find out optimized routes particularly suited to electrical automobiles.
