Abstract
The invention is the use, in an electric vehicle, of a fluid having a boiling point in the range of from 200° C. to 400° C. and a boiling range below 80° C., said fluid comprising more than 95% by weight isoparaffins and less than 3% by weight of naphthens, a biocarbon content of at least 95% by weight, containing less than 100 ppm by weight aromatics.
Claims15
Method for cooling components of an electric or a hybrid vehicle, said method comprising:
- using a fluid having a boiling point in the range of from 200° C. to 400° C. and a boiling range below 80° C., said fluid comprising more than 95% by weight isoparaffins and less than 3% by weight of naphthens, a biocarbon content of at least 95% by weight, containing less than 100 ppm by weight aromatics;
- wherein said components of the electric or hybrid vehicle comprise at least one of a motor, power electronics, a rotor of the motor, a stator of the motor, a battery, or a combination thereof.
Method for lubricating components of an electric or a hybrid vehicle, said method comprising:
- using a fluid having a boiling point in the range of from 200° C. to 400° C. and a boiling range below 80° C., said fluid comprising more than 95% by weight isoparaffins and less than 3% by weight of naphthens, a biocarbon content of at least 95% by weight, containing less than 100 ppm by weight aromatics;
- wherein said components of the electric or hybrid vehicle comprise at least one of a motor, bearings between a rotor and a stator of the motor, a reducer of the motor, a transmission, or a combination thereof.
