The world is rapidly accelerating development and release of new energy vehicles (NEVs). Since the construction of electric powertrains differs significantly from those of combustion engine vehicles, manufacturers and suppliers of the industry need to reinvent themselves to adapt the production and assembly of critical electric vehicle components. A major challenge in quality assurance in the new energy business is the need to meet the increased demand for precision – in other words: metrology is changing too.
ZEISS eMobility Solutions enables you to adopt to this change by providing multiple advanced technologies for quality assurance to ensure the reliability, efficiency and safety of your NEVs.
Batteries play an important role in the performance, range and longevity of an electric car. Safety, service life, performance and cost are essential to ensuring the success of battery technologies. These factors need to be addressed every step of the way, from R&D to quality control and production. It’s necessary to control and understand the properties of the battery down to the material, electrodes, cells, modules and tray level.
Electric motors are true powerhouses – compact and light, but still capable of high speeds and enormous torques, even at slow speeds. All components need to fi t together precisely for these motors to generate so much power with such little wear. One challenge posed by the latest generation of motors involves the precise production and assembly of the hairpins and stator, as well as the manufacture of the stacks in the stator and rotor.
Power electronics is the energy hub of every battery-electric, hybrid and fuel cell vehicle, as it controls the flow of power between the battery and the electric motor. To make electronic components more efficient and reliable, it’s essential to control the quality of semiconductors, printed circuit boards (PCBs) and finished modules across different length scales.
In a FCEV, the fuel cell system provides all of the energy needed to power
the electric motor. In the fuel cell stack many individual cells are arranged in series
and connected. The process to construct the fuel cell system
requires the highest quality standards in production and development of
each individual component.
Electric vehicles have very different powertrains – with either a single-speed or two-speed transmission instead of up to nine gears found in combustion engines. The engine and transmission share a housing – reducing the number of components and weight, but not the quality requirements. A number of measuring and inspection steps are needed to ensure top performance, low wear and tear, and quiet operation.
New Energy Vehicle parts are rarely produced in a single location. Yet measurement and inspection issues can pop up in any country and at any supplier. Our global network of application engineers and service are here to help solve your quality assurance challenges so you can keep traceability and quality at a consistently high level.
