Embodiment
In order to be better understood upon implementation process of the present utility model and implementation result, below with reference to accompanying drawing to this practicality
New specific implementation process is described in detail.
The utility model provides a kind of suspention small rail car electric power system, as shown in figure 1, including the wiping for providing alternating current
Line 20, the dolly driven on suspention track 30 by electric machine assembly is arranged at, dolly passes through the small suspension system 40 described in Fig. 1
Hang under track 30, and moved under the driving of electric machine assembly along track 30.The suspention track that the utility model is related to is small
Car provides region inner orbit for urban compact community and circulates traffic, and orbit suspended is each hung under track in certain altitude
Dolly is the suspention compartment for accommodating 1-5 people.
The electric machine assembly includes motor 72 and motor driver 71；The motor driver 71 passes through vehicle-mounted current-collector
10 to the power taking of trolley 20, as shown in Fig. 2 the output end of the current-collector 10 connects a constant current constant voltage dc source 50, it is described
The output end of the battery pack in parallel of dc source 50, the dc source 50 and battery pack connects motor by direct current supply line 90
Driver 71.
The pressure limiting of dc source 50 is less than cell voltage, such as less than cell voltage 5V or so, and it is specified that constant current is less than battery
Charging current.The power of dc source 50 driving power required when being traveled at the uniform speed slightly larger than small rail car, and add less than dolly
Required driving power when fast；The maximum discharge power of battery pack is more than required driving power when dolly accelerates, maximum charge power
The power that motor driver 71 conveys to direct current supply line during more than braking.
The battery pack includes battery protecting plate 61 and battery 62, and the battery 62 is chargeable lithium cell.
The limit value of voltage is less than the ceiling voltage that battery protecting plate can be born in direct current supply line 90, while is less than direct current
Power supply 50 reversely bears voltage.When charging current exceedes maximum license electric current, battery discharge current exceedes maximum discharge current,
When charging voltage exceedes situations such as maximum charging voltage and occurred, battery protecting plate 61 will use safeguard measure, protect battery not by
Damage.
Dc source 50 is charged using constant current mode to battery 62, when cell voltage reaches the voltage of dc source, electricity
Pond 62 does not recharge, and keeps certain remaining charging capacity, and at this moment battery should can absorb motor in a braking procedure and drive
The energy that device conveys to direct current supply line.
In direct current supply line 90 and motor driver 71 is connected to, when dolly travels at the uniform speed, Dc source power is more than dolly
Required power, dc source is powered to trolley driver, and when cell voltage is less than dc source pressure limiting, dc source is simultaneously right
Battery charges.
During Accelerating running, the electric current that constant current constant voltage dc source 50 is powered to dolly increases up to dc source Constant Electric Current
Stream, DC power output voltage drop to identical with cell voltage, and battery 62 enters discharge mode, battery and dc source parallel connection
Powered to motor driver 71.
When dolly retarding braking, motor driver 71 is raised in direct current supply line 90 to discharging in direct current supply line 90
Voltage, when the voltage in direct current supply line 90 is higher than dc source pressure limiting, dc source 50 enters reverse blocking state, battery
62 enter charge mode, absorb braking energy.
After battery 62 is charged to ceiling voltage, the charging current of battery 62 reduces, it is impossible to absorbs and is all transmitted back to direct current supply
Braking energy on line, the voltage in direct current supply line 90 continue to raise.Burnt to protect battery not to be reversed electric current, it is described
Dc source and a battery pack energy absorption device 80 also in parallel, voltage of the energy absorption device 80 in direct current supply line 90, which exceedes, to be inhaled
When energy device setting starts voltage, the energy in direct current supply line is consumed with form of thermal energy, until in direct current supply line 90

Dc source 50 has anti-reverse device, when voltage is higher than DC power output voltage in direct current supply line 90, prevents
Reversing device prevents current direction dc source.
The suspention small rail car electric power system that the utility model is realized, using the dc source of constant current constant voltage, when dolly needs
When wanting high current, output voltage reduces and arrives cell voltage, and battery parallel power supply, there is provided required power during acceleration；When needing electricity
Stream is when being less than dc source continuous current, dc source alone bear powered operation, reduces the working time of battery.Trolley is only
Power calculation capacity when needing to travel at the uniform speed by small rail car, the requirement to trolley load-bearing capacity, battery master can be reduced
The driving power of dolly is provided when accelerating, during trolley travelling, only few time participates in power supply, battery capacity
Demand is small, service life length.
Above by reference to preferred embodiment of the present utility model has been illustrated, not thereby limit to right of the present utility model
Scope.Those skilled in the art do not depart from any modification made in the scope of the utility model and essence, equivalent substitution and changed
Enter, all should be within interest field of the present utility model.
