Battery systems

Type of test: 

Assem­bly inspec­tion of lithi­um-ion batteries. 

 

Chal­lenge:

Due to pro­duc­tion or assem­bly errors, the con­tact, insu­la­tion and elec­trolyte foil is dam­aged in some batteries.

 

Pos­si­ble consequences:

A short cir­cuit can be the result. This can lead to a high ther­mal reac­tion of the elec­trolyte. The result­ing out­gassing caus­es the bat­tery to swell exter­nal­ly. Inflat­ed, deformed, out­gassed lithi­um-con­tain­ing bat­ter­ies can lead to explo­sions and fires.

 

Advan­tages of CT testing:

  • Dis­man­tling of bat­ter­ies in small devices is not nec­es­sary for the test. The devices can there­fore be used imme­di­ate­ly after the test
  • By sort­ing out defec­tive bat­ter­ies, high­er qual­i­ty can be guar­an­teed, and pre­ven­tion against legal dis­putes and neg­a­tive press in case of a fire can be operated

Automated inspection of hairpins

Challenge:

The stability of the hairpin joint is crucial for the reliability of electrically powered vehicles. Laser welding can be carried out according to different principles. However, this can affect the quality of the joint by process fluctuations resulting in undesired deviations.

Possible consequences:
Due to ambiguity in the quality of joints, high
failure rates can occur.

Advantages of a CT inspection:

  • Quality feedback within minutes
  • Statistically evaluable results thanks to Microvista's automatic analysis: 40 stators/day inspected
  • Only 165 €/part including an informative report.

Pore analysis of a cylinder head

Challenge:

In order to achieve the highest possible ranges as well as low emissions, lightweight construction continues to be a primary goal in vehicle construction, regardless of the type of drive. Light metal casting is characterised by its ability to produce complex parts with a high degree of automation and recyclability. However, high technological demands are placed on the components, including mechanical load-bearing capacity under more complex stresses and simultaneous mass reduction.

Potential consequences:

A cylinder with poor quality leads to damage to the cooling system and ultimately to engine failure.

 

Advantages of a CT inspection:

  • Visualisation of pores in the cylinder head and colour classification of the pores according to their volume is possible.
  •  The exact position of each pore and thus the potential risk it poses can be determined.
Testing of wall thicknesses of an exhaust manifold.

Challenge:

The exhaust manifold is one of the most heavily loaded components of an engine. For this reason, the actual and desired condition of the wall thickness should be compared. Only with a sufficient wall thickness can the manifold withstand the shock-like inflow of exhaust gases and the resulting pressure front, as well as the many heating and cooling cycles in the long term.  

Possible consequences of undetected deviations:

The notch effect of blowholes can cause a crack in the manifold. Partial breakthroughs can also occur if the wall thickness is too small. This leads to a change in the pressure conditions in the manifold, which reduces engine performance and, at the same time, increases fuel consumption. In addition, there is a high noise level from the direction of the engine and a clearly perceptible exhaust smell in the interior.

Advantages of a CT inspection:

  • Fast and automatic detection of relevant quality defects 
  • Avoidance of scrap refinement 
  • Detection of defect focal points through statistical evaluation of the results.

Assembly inspection of lithium-ion batteries.

Challenge:

Due to production or assembly errors, the contact, insulation and electrolyte foil is damaged in some batteries.

Possible consequences:

A short circuit can be the result. This can lead to a high thermal reaction of the electrolyte. The resulting outgassing causes the battery to swell externally. Inflated, deformed, outgassed lithium-containing batteries can lead to explosions and fires.

Advantages of CT testing:

  • Dismantling of batteries in small devices is not necessary for the test. The devices can therefore be used immediately after the test
  • By sorting out defective batteries, higher quality can be guaranteed, and prevention against legal disputes and negative press in case of a fire can be operated

Comprehensive inspection of an aluminium wheel carrier with complex bionic structure.

Challenge:

Additive manufacturing requires carefully set process parameters that are optimised in iterative steps during the product development process. Fast and comprehensive feedback on product quality is of paramount importance for shortening the development phase.

Possible consequences of undetected defects:

Missing and insufficiently validated process quality can result in high reject rates. Especially with regard to safety-relevant parts of the chassis, additional risks arise that can lead to component failure and create the risk of an accident.

Advantages of CT inspection:

  • Shortened development cycles
  • Addressing risks identified by FMEA
  • Reduction of required expensive prototypes through non-destructive testing for a variety of features.

Assembly inspection of medical devices

Challenge:

To detect malfunctions, damage or collisions that cannot be traced after disassembly of the medical device. 

Possible consequences:

Blockages can cause some devices to malfunction during use.

Advantages of a CT scan:
Complete digitisation takes place without the application of force during the measurement, which makes it possible to measure, analyse as well as subsequently process filigree and soft components. The inspection takes place quickly and reliably in the assembled state. During the evaluation, the movements in the component can be recorded, whereby the blockage can be found.
