Specifically, energy storage device 11 can be the arbitrary device for being used to store electric energy in the prior art.Preferably, this reality
Applying the energy storage device 11 in example is supercapacitor device.Supercapacitor device is a kind of electrochemical element, and thermal energy storage process is simultaneously
Do not chemically react, and thermal energy storage process is reversible, thus supercapacitor device repeated charge can achieve it is hundreds of thousands of
It is secondary, and not will cause environmental pollution.In addition, supercapacitor device have very high power density, be battery 10 to
100 times, it is suitable for short time high-power output, charging rate is fast, mode is simple, can use large current charge, can be tens
It is quick charge truly second to charging process is completed in several minutes.In further example, it is with energy storage device 11
The power supply system of super-capacitor device is mounted in for overhead rail train.There is power supply unit in each station setting, each
Rolling stock section is also equipped with power supply unit.When overhead rail train operation, every station just utilizes the power supply unit at station to be
Super-capacitor device charges so that super-capacitor device storage completely guarantees the electric energy at least one station of overhead rail train operation；When
When overhead rail train returns to rolling stock section, the power supply unit using rolling stock section is that super-capacitor device charges so that super capacitor fills
Set the electric energy that storage completely guarantees at least one station of overhead rail train operation.Using the power supply system of super-capacitor device, in the air
Track train permutation vehicle electric energy is charged to 100% from 0% and is no more than 30 seconds, and charging current will not cause impact shadow to periphery power grid
It rings, charging and discharging energy conversion efficiency is not less than 90%, and the recovery efficiency for the renewable sources of energy that the train braking of recycling generates is not low

14 first receive the second work of the first work state information of energy storage device 11 acquired in monitoring device 13, accumulator plant 12
Status information, then control device 14 using inner setting algorithm to the first work state information, the second work state information into
Row Data Analysis Services determine whether the current working status of energy storage device 11 meets to column according to the result of Data Analysis Services
The setting condition that the electrical equipment 15 of vehicle is powered, and the current of accumulator plant 12 is determined according to the result of Data Analysis Services
Whether working condition meets the setting condition powered to the electrical equipment 15 of train.For example, such as supercapacitor device
Energy storage device 11 power supply line may be caused biggish electric arc occur, and then burn out electricity consumption if its discharge current is excessive
At this moment equipment 15 controls and determines that supercapacitor device is in improper work according to the discharge current in the first work state information
Make state, and the connection circuit of cutting supercapacitor device and electrical equipment 15, enabling battery to electrical equipment 15 into
Row power supply, guarantees the redundancy of power supply system of train 1.For example, the energy storage device 11 of such as supercapacitor device, if
The temperature of supercapacitor device is excessively high, will seriously affect the service life of supercapacitor device, at this moment control device 14
Determine that supercapacitor device is in abnormal operating state, and the super electricity of cutting according to the temperature in the first work state information
The connection circuit of case and electrical equipment 15 enables accumulator plant 12 and is powered to electrical equipment 15, guarantees train
The redundancy of power supply system 1.Similarly, when control device 14 determines that accumulator plant 12 is according to the second work state information
Abnormal operating state, and the connection circuit of cutting accumulator plant 12 and electrical equipment 15,11 pairs of energy storage device of enabling with
