Product introduction 

Change the way of energy supply of metro engineering vehicle, and driving the traction motor by battery stored energy, to achieve the purposes of no emissions, low noise pollution and long mileage. 

Product characteristics 

Double power supply, when the traction battery is used for power supply, it can ensure the normal operation of metro engineering vehicle under the condition of no electricity in the third track;

The battery can be charged in two ways by third rail or ground power supply. The charging time is short and is 30 minutes. 

The battery has a sustainable high power output and energy recovery when braking; 

The battery has an average service life of 8-10 years, which is characterized by no fuel consumption and smoke emission, low noise, high efficiency and simple maintenance.
