Description
Technical field
The present invention relates to supply vehicle technical field, more particularly to a kind of mixed type UPS electricity for sharing pure electric chassis storage battery
Source car.
Background technology
With the rapid development of the national economy, to the power reguirements more and more higher of electric energy in daily production and living, it is traditional
Power supply vehicle of meet an emergency (vehicle-based generator set pattern) is gradually not applied for higher and higher electricity of protecting and required.It is on for guarantor protecting electricity
The continuity of testimony electricity, then occurs obvious power interruption recovering time interval if power-off occur and restarting generator；If order electricity
The generating set of source car is awaited orders in no-load running, then very big to unit self-inflicted injury；Even if to sacrifice the generating set life-span as generation
Valency makes unit is hot standby to await orders, and more than ten second time is generally required from zero load to full-load run, and it switchs automatic closing switching
In the presence of obvious instantaneous interruption, it is difficult to independently meet that guarantor's electricity of some high standards requires.For the UPS that solves the above problems
(Uninterruptible Power System/Uninterruptible Power Supply), i.e. uninterruptible power system
It is introduced into vehicle-mountedization, i.e. ups power car.UPS is that battery is connected with control main frame, will by modules such as main frame inverters
The direct current of battery is converted into civil power in system.When civil power input is normal, UPS will be supplied to load to make after civil power voltage stabilizing
With, while it also charges to self-contained battery；When commercial power interruption (forced outage), the direct current energy of battery is passed through inversion by UPS
The square normal load of device switch transition continues to supply alternating current, is raced against time for cut-in stand-by power supply, effect is not powered off so as to reach
Fruit, load normal work is maintained, it is without damage that protection loads soft and hardware.When protecting electric as shown in Figure 1 by ups system be serially connected in by
In the circuit of protection, AC power input is changed into dc source by rectifier.Inverter is by this dc source or from electricity
The dc source in pond is changed into exchange and is supplied to load.It is even several that a few minutes can be provided when mains failure by batteries
The back-up source of ten minutes.Transit time is provided for unit starting, while ups system has quality of power supply height, using energy-conservation
The advantages that environmentally friendly, taken action especially suitable for the important electricity of protecting such as large-scale cultural and sports activity, high-level meeting.Therefore ups power car is more next
More paid close attention to by relevant departments.
Current existing ups power car has two types, and one kind is pure ups power car, i.e., only carried on vehicle battery with
Ups system.The battery that this ups power car is commonly equipped with is relatively more, and the fully loaded preparation time of complete machine is long, and generally ten
More than a few minutes even one hour, this ups power car can individually be completed to protect electric work when protecting electric for low-power load, be not required to
Want the coordinating operation of generating set.But generally require for high power load and be used cooperatively with generating set, ups power car only rises
To the effect of transient power.As hybrid ups power car, this ups power car are provided with ups system and generator simultaneously
Group, the battery that the car is equipped with is less, and the fully loaded preparation time of complete machine is also shorter, generally a few minutes.UPS electricity in this vehicle
The transient power that source starts as generating set.Mixed type ups power car can also use the independent bringing onto load of generating set, as
Generator car use.For function advance and practicality, hybrid ups power car is wider than the pure ups power car scope of application,
Practicality is also higher, and vehicle is also more advanced in itself.
The either pure ups power car of existing ups power car or mixed type ups power car are with common two classes chassis
Ups system or unit is added to form.Because substantial amounts of battery is included in ups system, therefore this sample loading mode has the following disadvantages.
1st, the heavier-weight of battery, volume is larger, and the load distribution and general layout for vehicle are that have certain be stranded
It is difficult.Therefore, it is difficult to accomplish powerful ups power car to be limited by two class chassis by size and weight, or work it out
Supply vehicle volume ratio considerable influence trafficability limits the vehicle scope of application.
2nd, the quality of battery directly affects the stabilization of whole system in ups system, therefore battery price is often
Costly, under prior art conditions, battery needs regular charge and discharge maintenance maintenance.And power supply vehicle of meet an emergency belongs to and " maintained an army
Thousand, use military forces for the moment " rush repair equipment, power supply vehicle of meet an emergency belongs to idle state under normal circumstances, if battery is not busy for a long time
Putting then can " hungry to death ".For prolonging service life of battery, the discharge and recharge that ups power car must not irregularly carry out no practical use is protected
Support, not only increase workload, and waste the energy.
Electric chassis operation principle is power source of the battery as chassis, by motor control module to power at present
Motor is controlled, and motor control module changes the rotating speed of power motor by way of frequency modulation, realizes different travel speeds.
Battery is controlled by Battery control module simultaneously.Electric chassis has used more next as a kind of new energy chassis
It is more, but the technical bottleneck of battery still governs the further genralrlization of electric chassis, restraining factors be mainly reflected in
Lower two aspects：
1st, in order to ensure vehicle endurance and load capacity, chassis is needed to carry a large amount of batteries, and this is not only added
Chassis deadweight also takes up the valuable space in chassis both sides；
2nd, electric chassis charging must use special charging pile, and charging pile is expensive and not yet promotes the use of,
Only just have in highway or indivedual conditional units.Because above reason, electricity of the general unit to this energy-conserving and environment-protective
Hang back on dynamic chassis.
Ups power car and electric chassis have an identical characteristic, are exactly to provide energy using battery.And institute
The battery used is accumulation energy type battery.And the voltage range of battery is 350V-500V.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide one kind energy-conservation, efficient electric chassis ups power car, knot
The design feature of pure electric chassis and ups power car is closed, their advantages is given full play to and makes up shortcoming mutually, realize space, the energy
More reasonable disposition, simplify line service, improve operating efficiency, reduce energy loss.
Pure electric chassis is combined with ups power car has two schemes：
Scheme one：Exploitation electric chassis is matched according to ups power car accumulator capacity.
Scheme two：Exploitation ups power car is matched according to existing electric chassis accumulator capacity.
Because the battery brand and capacity of national relevant regulatory requirements electric chassis are to need to put on record and carry out accordingly
Form experiment.Need to re-start qualification test once battery brand or capacity is changed, this needs to spend substantial amounts of people
Power, material resources, financial resources.Chassis, which is individually developed, for this minority's product of ups power car is undoubtedly a kind of waste.So from this side
Scheme one is not so good as scheme two for face.
Because accumulator capacity is certain, if increase ups system load capacity, preparation time can accordingly reduce.
Ups system preparation time is such as improved, then load capacity can decline.It is not so good as mixing in view of the superiority of pure ups power car
Type ups power car.Therefore the present invention is using a kind of ups power car based on pure electric chassis.
In order to reach above-mentioned purpose, solution of the invention is：
