Loss reduction by optimised power intake |
 |
evaluated |
 |
|
|
| Some electric vehicles are equipped with a control tool regulating the power intake according to distance from substation. The system aims at avoiding negative effects on power electronics through high currents. As a side effect catenary losses are reduced.

Impacts on energy efficiency:
|
| |
|
|
|
Energy efficiency potential for single vehicle: < 2% |
| |
|
|
|
Energy efficiency potential throughout fleet: < 1% |
| |
|
|
|
|
No data on saving effect are available. Given that catenary losses account for about 10% of the energy drawn from substations, and the fact that the control tool regulates the current only within a small range, the overall saving potential will be less than 2%. |
