Abstract Bringing new unknown technologies and unique features into a market is one option to acquire new customers. Today, some electric vehicle manufacturers follow this strategy to conquer a market (e.g. gullwing doors of Tesla Model X, carbon-fibercarbody with coach door entry of BWM i3). This represents a considerable risk for Original Equipment Manufacturers (OEM)s and their suppliers since the impact of a totally new and unknown technology with extra charge to the customers is unknown. On the other hand, a new car model with unique stunning features may lead to a severe buying interest. In this paper, a new assessment methodology for electric vehicle technology concepts is presented on the basis of the Quality Function Deployment (QFD) method. This methodology allows a technical-scientific assessment concepts including energy storage and powertrain in the early development phase and also a comparison of variants. The principle of this methodology is explained by the example of a battery charging station. Subsequently, the evaluation process for an innovative electric vehicle with two complementary energy storage devices (lithium-ion accumulator and an additional flywheel storage device) is outlined. Both or a single storage devices can be in operation with respect to the power requirement in a specific driving situation (acceleration, braking, steady drive). This hybrid storage concept is implemented in an electric scooter prototype and is in a status of road testing. The paper shows how the method for integrating customer requirements and new technical features can be used in a concept evaluation.
