This is a game-changer for all those who complain about how long it takes to charge electric cars. High-performance charging stations that work with direct current (DC) and several hundred kilowatts are attractive for public charging stations and gas stations that want to offer a solution for electric cars.
A family going on holiday will no longer ask if an electric car makes sense or if the time needed to charge the battery will make the travel time too long. Now, stopping off at a highway charging station makes no difference to the total time.
Heat is generated wherever so much electricity flows. This heat must be dissipated in order to prevent the charging station from overheating and damaging sensitive electronic components. An effective intake air system is therefore necessary for models with high nominal power. Charging stations with an effective intake air system offer operators a huge advantage: more vehicles can be charged at a station in the same period of time, which allows greater revenue.
However, there is a certain risk associated with cooling charging stations using air. Air can contain fine dust and organic materials such as rust, tire debris, soil particles, pollen, leaves, and tiny insect parts, which can get inside the charging station. These can damage the sensitive electronic components if they are allowed to accumulate on them. If moisture penetrates into the charging station, components can also corrode, causing short circuits.
In order to protect the electronic components and optimize the availability of the charging stations, Freudenberg Filtration Technologies has developed special filter panels, some using the P15/500 S filter medium. A high-performance nonwoven (Filter Class ISO Coarse 75%) is welded into the frame to provide a dustproof seal and ensure stability as well as reliable protection from dust, dirt particles, and water droplets. When using these filters, charging stations can achieve a protection class of IP 54. The filter medium’s progressive structure and high dust holding capacity result in an exceptionally long service life.
The filter panels are designed in such a way as to allow flexible adaptation to the dimensions of the ventilation space. The filter element is extremely stable and so only requires minimal mounting to be installed in the charging station. In most cases, a slide-in rail or clamps is all that is required to fasten it in place. Maintenance is also simple and requires no expert knowledge. These factors also make it easy to change the filter and reduce maintenance costs.
To achieve reliable operation for the charging stations, the filter panels should be changed once or twice a year — depending on the ambient air quality. On roads subject to heavy traffic or in rural areas, it is sensible to change the filter towards the end of the pollen season.
The new filter elements provide the perfect protection for sensitive electronic components and minimize the risk of downtime.
