We protect charging solutions for electric vehicles
The urgent need to globally expand the charging infrastructure for electric vehicles is a critical issue. According to the Joint Office of Energy and Transportation, there were approximately 180,000 electric vehicle charging ports in the United States in early 2024. The International Energy Agency reported that new electric car registrations reached 1.4 million in 2023, representing a significant increase of more than 40 percent compared to 2022. This means that it’s vital for both existing and future charging stations to function reliably. To help address this, MANN+HUMMEL develops advanced filtration solutions for e-mobility that protect the cooling units of charging stations from everyday wear and tear. Our filtration concepts, available for both air-cooled and liquid-cooled charging stations, offer excellent filtration performance combined with highest energy efficiency. By implementing these intelligent filtration solutions, we contribute to the creation of a reliable and robust charging infrastructure.
Air filters for fast charging stations (DC)
An electric charging station's performance depends heavily on the effectiveness of its cooling system. Charging electric cars at DC (direct current) stations generates significant heat. To dissipate this heat, many manufacturers rely on air cooling. To ensure proper functioning of direct current charging stations, it’s essential to prevent dust and dirt particles from entering the interior of the station. Classic filter mats are commonly used for this purpose. While their low filtration efficiency generally increases dust holding capacity, it comes at the cost of high particle penetration (especially fine dust) and significant pressure loss. The consequences are wear and tear, increased maintenance effort, higher risk of failure, and greater energy costs.
MANN+HUMMEL's air filter elements provide many advantages that make them the leading solution for charging stations:
- Optimum filtration of pollutants
- Enhanced protection of electronic components
- Excellent noise reduction
- Highest filtration efficiency
- Increased cooling capacity
- Prevention of system shutdowns
- Reduced maintenance time for filter changes
- Smart service concepts
- Customizable installation concepts
- Bespoke design optimizations
- An extensive portfolio of filter media
Ion exchange filters for liquid-cooled fast charging stations
In liquid-cooled charging stations, our IonFree ion exchangers ensure greater safety. They help protect electric car charging stations from short circuits, are easily adaptable, and enable efficient maintenance of fast chargers with liquid cooling. Their highly innovative features include:
- Ion exchange technology ensuring low conductivity of the coolant
- High-quality ion exchange resin enabling superior capacity and purity
- Various sizes, installation positions, connection types, and orientations allowing seamless integration into nearly any installation space
- No loss of high-quality coolant, as only the filter cartridge needs to be replaced
Further smart and sustainable solutions for charging stations
Consultation, service, and sustainability all play an essential role in the expansion of the charging infrastructure for electromobility. Intelligent digital solutions are similarly crucial when it comes to helping shape the clean mobility of the future. Manufacturers can always safely rely on MANN+HUMMEL's Digital Solutions and sustainability approach.
Our digital solutions for charging stations streamline thermal management. Thanks to their predictive maintenance system, they also enable maintenance teams to replace filters at the optimal time. This innovation also helps specify new filter requirements based on current outdoor air conditions. This provides our customers with both substantial cost and logistical advantages.
From recycling production waste and used filters to implementing software tools for life cycle analysis and reducing CO2 emissions with energy-efficient filters - our dedicated approach to sustainability enables environmentally friendly charging and cooling solutions for electromobility.
