The CCS2 European standard DC gun complies with the IEC 62196-1-2014 and IEC 61851-2015 standards. It uses ultrasonic terminal welding technology to reduce the contact resistance to almost zero. This lowers the temperature rise during charging and makes it safer and more durable. The product has a rated current of 300A and a maximum current of 500A. It does not need an extra cooling source as it is air-cooled naturally.
