<i /> Emergency charging system of accumulator battery electric train of subway
The possibility of charging the battery of the electric rolling stock of the Moscow Metro of models 81.765 / 766/767 and their modifications from an independent power source is analyzed. The use of an ultrahigh-energy pulse capacitor is proposed as an independent power source. The introduction of this combined power source will help maintain the operational state of on-board systems during the operation of electric rolling stock when the voltage on the battery is lower than 66V and there is no voltage of 825V on the contact rail.
