Electrified drives help to reduce CO2 emissions during driving and to decrease air pollution caused by pollutants such as NOX and particulate matter. The resulting increase in the importance of alternative drives is currently accelerating the development of new filter applications at MANN+HUMMEL.
In battery electric vehicles, the battery system is the most valuable component. In particular, lithium-ion cells with high storage capacity can only be operated in a narrow temperature window. Increased temperatures lead to premature loss of performance, strong overheating leads even to the destruction of the battery cell. The right heating and cooling strategy when charging and driving is therefore crucial for the system durability. In addition, electric motors and power electronics must also be cooled. Besides the protection against overheating, it is important to ensure, for example, that there are no large pressure differences between the environment and the inside of the battery system and that no condensate from the humidity in the battery system occurs, which can lead to short circuits. For this purpose, MANN+HUMMEL offers numerous filtration solutions that reliably protect the battery system:
