Stable thermal management for the e-car of the future

E-mobility is one of the major issues of the future and continues to gain significance with rising fuel prices, low-emission zones in cities, increasing volumes of traffic and the associated environmental impact. The automotive industry is still working intensively on solutions to familiar problems such as range and charge as well as cell fires, which are often associated with electric vehicles. The temperature control of accumulators and batteries is another challenge for which GVI® has the answer.

The GVI® structure, which can withstand high mechanical loads, makes it possible to realise lightweight construction designs. Weight, resources and costs are saved thanks to the complete integration of multi-stage thermal management in the multifunctional B:HOUSE® housing.

The stability, protection and controllability of the interior temperatures are reminiscent of a bee house in nature.

Crash-proof and vibration-resistant integration of multifunctional battery housings in modern electric vehicles

  • GVI® structures are high-strength and rigid – comparable to sandwich structures.
  • It is possible to completely encapsulate the battery thanks to the double-walled construction of thin stainless steel sheets.
  • The battery is securely protected against external influences. In the event of fire or damage to the cells, no ecologically harmful are released into the environment.
  • Battery cells and/or modules can be fixed vibration-proof in the multifunctional housing. Forces and moments are transmitted directly to the vehicle structure via the insulation on the outside of the housing without additional supporting elements. This also prevents thermal bridges.
  • The multifunctional B:HOUSE® housing can be designed as a component of the load-bearing vehicle structure.

Examples of use

GVI® battery housing for thermal management and crash safety

Effective thermal management is required for all battery systems, whether Li-ion or NaNiCl. GVI® technology is used to create multifunctional battery housings that enable both complete thermal management and crash-proof encapsulation of the battery. In this way, they make an active contribution to environmental protection – as well as to the safety of people and machines.

Effective GVI® insulation in the exhaust-gas system

Among other things, GVI® insulation serves to store heat in the catalytic converters of hybrid vehicles. The insulation is also ideal for reducing heat radiation near electronic components.

GVI® heat storage for engine preheating

There is also an increasing demand for highly effective, thin insulation for heat recovery systems on combustion engines in order to significantly improve performance. The same applies to the storage of sensitive heat, for example for heating the passenger compartment or preheating the engine.

The GVI® heat storage makes it possible, among other things, to store waste heat (engine oil/cooling water) and to achieve the lowest possible heat losses from the storage tank while at the same time achieving housing structures that can withstand high mechanical loads. This is also possible thanks to engine encapsulations with tailor-made shielding plates. In addition, a general improvement in exhaust gas emissions is achieved in the engine ignition phase.

All insulations can be designed to be adjustable to avoid overheating in case of need.
