The temperature class for battery off-gas explosion proof equipment is recommended to be T2 according to the IEC 60079 standard. The gas group is identified as Group IIC according to the IEC 60079-20-1 standard.
According to the IEC 60079 standard, the temperature class for battery off-gas explosion proof equipment is recommended to be T2. The gas group is identified as Group IIC according to the IEC 60079-20-1 standard. Table 4-2 lists the MESG values of identified battery gases and the MESG value of the combined battery gas.
When the gasses produced from a lithium-ion battery are combusted rather than accumulating, the explosion risk goes down substantially. Limiting the oxygen to the fire will reduce the chance of prolonged combustion with lower temperatures. However, the off-gassing and hence the explosion risk increases.
The temperature class for battery off-gas explosion-proof equipment is recommended to be T2. The specific gas group for explosion-proof equipment is classified according to their maximum experimental safe gaps (MESG), as defined in IEC 60079-20-1. For battery off-gas, the temperature class is T2.
The explosion pressure limit is set to 0.5 barg. Above this pressure, the bulkheads will be damaged. With a ventilation rate of 6 ACH, it should be sufficient to avoid such pressure if 350 liters of battery gas is released in the room, which corresponds to a cell or module of 115-175Ah.
Battery cells cannot be explosion proof. However, equipment installed around high gas concentrations, such as the extraction fan of the battery system or battery room, can pose a high threat. Figure 4-1 shows the different Temperature Class categories and indicates the dependency on ignition temperature for determination.
