• Battery Cycling
  

  Lithium Ion is becoming the technology choice for HEV, PHEV, as well as many stationary applications. With such large battery packs it is important to understand how the individual cells and packs will behave in a variety of scenarios. One of the main drawbacks for Lithium Ion cell technology is the potential for thermal runaway more

• Bearing grease selection

  Rolling-element bearings are used for the precise guidance of moving parts. Frictional losses are extremely small because the bearings rest on rolling elements, enabling very heavy loads to be adsorbed. Rolling-element bearings may be lubricated with greases or oils depending on the point of use. Lubrication is necessary to prevent direct metallic contact between rolling elements and bearing rings, thereby preventing wear due to welding, friction, material fatigue or corrosion more

• Battery Safety (thermal runaway)
  

  Lithium ion battery technology offers many advantages in portable power application but one major concern is safety – thermal runaway of the device in both normal and abusive situations. In the following article, it will be shown that by means of adiabatic calorimetry, it is not only possible to test single components but also complete lithium ion batteries. From this information batteries can be evaluated for their hazards potential, but more importantly, these tests can be used to design inherently safer cells, providing key design information during the development process – reducing development costs and increasing product safety more
