Traction equipment is cooled by ventilation to prevent over-heating. The energy needed for ventilation can be substantially reduced by demand-controlled operation, i.e. by controlling ventilation power (e.g. the speed of the mechanical fans) according to actual cooling demand of the motor (or other traction equipment). The technology is wide-spread but not a standard yet.

Demand-operated ventilation is a feature of many but not all modern electric vehicles. In MU stock the main obstacle is additional cost and complexity due to the required separate auxiliary inverter. However, LCC are likely to be in favour of demand-operated ventilation even in MUs. |
