Abstract: Coolants based on alkylene glycols or derivatives thereof are useful for cooling systems in electric vehicles having fuel cells and/or batteries, preferably for motor vehicles, particularly preferably for passenger cars and commercial vehicles (known as light and heavy duty vehicles). The coolants contain additional corrosion inhibitors for improved corrosion protection in addition to specific azole derivatives.
