Power supply for metro engineering vehicle
Product introduction 

Provide two hybrid power supply modes including electricity + electricity and electricity + diesel to supply hybrid power to for metro engineering vehicle and provide energy recovery; Compared with traditional fuel powered power supply for metro engineering vehicle, it not only saves energy and protects environment, improves energy efficiency, but also ensures engineering vehicle safety under some special road conditions, such as tunnels, and improves safety and comfort. 

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.
