Main features

With the strong development of the electric drive car in the automotive sector, the market demand for containers suitable to host testing activities is growing, and in particular:

  • Containerized walk-in Climatic chambers for testing lithium batteries.
  • Container for the storage of lithium batteries.
  • Container for testing electric traction vehicles.

SITAL is able to offer containers complete with low and high temperature air conditioning systems, sized in relation to the different testing needs. There is also povided a safety system in compliance with the hazard levels defined by the EUCAR consortium, as per opposite table.

The containerized walk in climatic chambers relized by SITAL are particularly suitable for outdoor installations and are provided with CE certification according to the Machinery

EUCAR Consortium – Lithium batteries hazard levels

Hazard Level Description Criteria for Severity Classification & Effects
0
No Effect
No effect. No loss of functionality
1
Reversible Loss of Function
No defect; no leakage; no venting, fire, or flame; no rupture; no explosion; no exothermic reaction or thermal runaway. Temporary loss of battery functionally. Resetting of protective device needed.
2
Irreversible defect/damage
No leakage; no venting, fire, or flame; no rupture; no explosion; no exothermic reaction or thermal runaway. RESS irreversibly damage. Repair needed.
3
Leakage Δ mass < 50%
No venting, fire, or flame; no rupture; no explosion. Weight loss < 50% of electrolyte weight. Light smoke (electrolyte=solvent+salt).
4
Leakage Δ mass ≥ 50% Fire or Flame
No fire or flame; no rupture; no explosion. Weight loss ≥ 50% of electrolyte weight. Heavy smoke (electrolyte=solvent+salt).
5
Fire or Flame
No rupture; no explosion (i.e. no flying parts)
6
Rupture
No explosion. RESS could disintegrate but slowly without flying parts of high thermal or kinetic energy.
7
Explosion
Explosion (i.e. disintegration of the RESS with externally damaging thermal & kinetic forces). Exposure to toxic substances in excess of OSHA limits.

Directive and REI 120 certification. In particular, SITAL uses its own production doors, opportunely designed in order to ensure the double requirement:

  • REI 120 certification
  • A thermal transmittance value suitable for the extreme temperatures of use

It is possible to use treatments or materials suitable for resisting the corrosive actions of internal and external agents:

  • For the internal surfaces: AISI 316 stainless steel cladding
  • For external surfaces: painting cycle in class C5M, according to ISO 12944-5 or, alternatively, use of stainless steel.
