Efficient Fast Charging of Electric Vehicles: Charging Connectors with SMA Technology

Fast-charging technologies are reaching their limits due to increasing charging power and thermal losses, necessitating complex cooling systems. Innovative charging connectors featuring shape memory alloys (SMA) solve this problem by actively increasing the contact normal force, which reduces contact resistance and thermal losses. The energy-self-sufficient SMA technology reacts autonomously to temperature changes, thereby minimizing the required cooling capacity, increasing energy efficiency, lowering maintenance costs, and extending the service life of the connectors – contributing to a more sustainable charging infrastructure.
