Along with advancements in EV technology to help sustain a cleaner future, Audi is looking to once again go the extra step. Audi recently filed a patent for a fast charging station that integrates a “CO2 collector” to reduce greenhouse gases.
How it works
Ambient air flows through a filter powered by a blower motor. The filter then adsorbs a portion of the carbon dioxide. Once the adsorption capacity of the filter is exhausted (full), the filter is then heated to release the remaining bound carbon dioxide. The heat used for the filter is waste heat utilized from the fast charger while a vehicle is charging. As you may know, fast charging generates large amounts of wasted heat. For example, at 350kw of charging power, up to 37 kW of waste heat is produced. This waste heat is then removed from the electric vehicle’s batteries and transferred to the charging station.
With over 130,000 public charging stations in the US, This can be a huge step towards a cleaner future and a massive win for Audi.
