Electric Vehicle Development

During the last years, electric vehicles have suddenly become more and more interesting and meanwhile all automobile manufacturers focus their attention on their development. The new understanding of mobility has resulted in new challenges for vehicle construction and their accomplishment requires a lot of capacity building and a large quantity of innovative energy.

In our function as a leading service provider for development we concentrate on the new technologies of electromobility and support our customers with proven expertise and considerable practical experience.

Benchmark & Concept Design

At the beginning of a carefully targeted electric vehicle development stands a far-sighted concept design with an eye to the future.

 

Architecture & Specification

Based on our customer’s requests we give a detailed and precise explanation of how we can meet the requirements placed on the planned product and how we are able to realise them in a cost-effective way.

Simulation

The use of simulation technologies makes it possible to clearly reduce development costs. The modelling of technical systems like Powertrain, energy flow or driving dynamics reduces the development time, because at an early stage of the development process tests can already be run and improvements be introduced.

Powertrain Control & Software

Today, software design constitutes a large part of the vehicle development process. The systems become more and more interconnected. In order to operate electric vehicles the use of sophisticated software is absolutely essential.

Battery Pack

Energy storage is one key to e-mobility. The development of a suitable battery pack constitutes a great challenge in many respects. The cell, packaging and climate control have to be tailored to the particular electric vehicle.

High Voltage & Integration

Developing electric vehicles entails new challenges which require innovative technical solutions. One of the most important subjects is the power supply by means of a high-voltage battery pack. In this regard, safety is the most important aspect. A specific design of the high-voltage architecture is the basis for an appropriate wiring, the use of the correct power distribution unit and an efficient EMC concept. Furthermore, it is necessary to choose and integrate suitable hardware components.

Low Voltage & Interface

Besides the alternative type of drive, an electric vehicle also offers the opportunity to take a fresh look at the electrical system architecture. Developing a concept car means operating standard components with new functions and voltage distributions. For example, using an existing relay and fuse box does not represent an optimal solution. Moreover, interfaces for the new technology are missing.

Testing

Extensive testing is necessary to guarantee functionality, safety and durability of the designed product. In order to avoid that deficiencies are discovered only at the end of the development and then lead to an unnecessary increase of costs, specific tests are run after each stage of development. Based on the V-Model, all stages of development – from modular software tests (SiL) to final vehicle tests – are carefully completed.

Prototype Build

Prototype build signifies the completion of the first development cycle. This decisive stage of concept development reveals the excellence and quality of the entire preparatory work. It becomes evident whether components and systems harmonize and if the targeted result will really be achieved.
