The alternator produces power to overcome the load which is connected to the alternator.

from the battery to the alternator

Efficiency of the high efficient alternator

This amount of power is equal to the alternator voltage (V) times the alternator current (I).

Efficiency of the high efficient alternator

ω Rotational speed of the alternator (rad. s–1

from the alternator to the fuse or circuit breaker box

The high efficient alternator to be implemented in vehicles

The alternator is to be directly linked to the torque meter and to the shaft of the drive train.

The alternator transfers the mechanical power of the brushless motor into electrical power.

The average efficiency of the alternator is to be calculated by means of formula .

The alternator is to be loaded with a battery and an electronic load.

At each speed the alternator is charged at 50 % of the maximum load.

Where the Valeo EG Alternator is fitted to an existing vehicle type, the baseline technology should be the alternator of the most recent version of that type placed on the market.

The standard deviation of the efficiency value of the alternator (ΔηΑ) is calculated by the following formula
