Substantially water-free antifreezes for cooling systems can be used as coolants and antifreezes without further dilution with water.

Antifreeze agents and coolants for fuel cells, storage batteries and batteries

Substantially water-free antifreezes and coolants are useful for cooling lithium rechargeable batteries.

Heat transfer liquid for cooling lithium storage batteries

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.

Coolant for cooling systems in electric vehicles having fuel cells and/or batteries containing azole derivatives and additional corrosion protectants

The present invention relates to coolants 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), based on alkylene glycols or derivatives thereof, which comprise additional corrosion inhibitors for improved corrosion protection in addition to specific azole derivatives.
