Power Storage Applications in Automotives
Power applications in automotives are dynamically experiencing changes and improvements. One of the benefits of slimming down the vehicle body weight is less power energy consumption. Getting more kilometers out of the same amount of energy can be possible by fully exploiting the technology available in the market. A multitude of innovative concepts, technologies and materials are in the market and are used in the vehicles and transport carriers today. The relative high costs associated hindered the development and implementation of advanced materials and production technologies.
Potential novel materials applications have large scope, but the focus on two issues:
- The development of innovative materials for batteries based on nanotechnology
- The development of new light weight materials and respective technologies for vehicle applications.
We already discussed reducing structural weight in Automotives Body Weight Reduction that discussed on different materials role in reduction of body weight of automotives. While, innovative automotive electrochemical storage applications based on nanotechnology technical content and scope is:
Ford has come up with volume production plans for large-capacity Li-ion rechargeable batteries that are being made targeting electric vehicles and other applications in automobiles. As per Ford, Li-Ion batteries are the obvious energy storage option for PHEV with 50% less weight and 30% less volume with
- High degree of application compatibility
- Well resolved SOC
- Historic research focus on high energy
- Reasonable power-to-energy ratio design flexibility
- Wider range of electrode material choices
- Long term cost potential
Lithium Ion Technology is one of the satisfactory methods that still most car manufacturers would agree for long distance EV use. Energy and power density, cost and safety improvements are needed at a higher ratio. The developmental projects shall solely address the development of innovative materials and technologies for battery components, material architectures and systems for automotive electrochemical storage at cell level within a responsible, sustainable and environmental-friendly approach looking at the entire life cycle. The affect of the battery properties at the nanoscale across a full cell includes modelling and simulation. The focus is on innovative technologies, architectures and chemistries and should address the issues like:
- performance, safety, recyclability and cost
- Potential capability for fast charging without significant life reduction
- Effect of bi-directional flow at charge stations
- Availability of other associated materials
- Eco-design and the environmental impact by material production
- Characterization, standardization and synergies with other applications.
Proof of concept in terms of product or process is encouraged as is participation from the manufacturing industrial sector within strong interdisciplinary consortia.
Globally many events take place on the power applications in automobiles and the industry members are thriving to bring a breakthrough in the technology.
