Background technology
The restriction wide variety of key factor of electric motor car is that electrical source of power energy density is relatively low at present.Due to car
The problems such as the installation dimension finite sum deadweight of load power supply so that it is efficiency is limited and distance travelled is short；Another factor
It is in vehicle travel process, to be only used for electric discharge at vehicle power, after electricity is exhausted, during stagnation of movement, is only used for charging,
And need the charging process of long period.
Currently employed dual power supply technology is to increase the auxiliary electricity of a super capacitor on the basis of main power source
Source, the shallow benefit when main power source in vehicle travel process discharges, improve main power source service efficiency and life-span,
And assist main power source to power to motor when accelerating or climb.Super capacitor auxiliary power system utilizes super electricity
Hold the advantage that power density is big, when vehicle touch at, can high-power charge so that it is can fill in the short time,
And in vehicle next one circulation driving cycle, the electricity being filled with is added in main power source；Meanwhile, electronic
Main power source can be assisted to power with the biggest discharge power supply when car accelerates so that the startup of electric motor car and acceleration
Make moderate progress.This dual power supply technology make use of the cushioning effect that the short time power electricity of accessory power supply imports,
Main power source small-power within the touch at time is mended electricity become in the long period stopped and in driving process
The small-power of section mends electricity, greatly improves the benefit electricity of main power source, adds in the traveling of vehicle operationally section
Journey.To vehicle after main power source electricity single sonorous stone the inoperative period charging, owing to the electricity of accessory power supply accounts for
The certain proportion of main power source, therefore the charging total amount of main power source is decreased by external charge device the most accordingly, residue
Electricity by accessory power supply complete charging.The time using external charge device is shortened accordingly.
Summary of the invention
It is narrower that the technical problem that present invention mainly solves is to provide a kind of most of the time power demand scope, little portion
The car having repeatedly touch at charge condition in moment significant power demand, and vehicle full-time employment period is had between timesharing
By power-supply system, it is possible to utilize of short duration charging to obtain bigger electricity, be stored in accessory power supply, and at vehicle row
During sailing, electricity in accessory power supply is added to active force power supply, or directly auxiliary equipment is powered, or must
Will time participate in main power source and power.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of power supply on vehicle system
System, including:
Carload controller, is monitored the state of main power source and each power device, judges and controls, and makes auxiliary electricity
Source and main power source, each power device form various collocation state；
One electrical source of power, mainly powers to drive system, can also absorb the feedback braking energy of described drive system,
Assist when needed and power to other auxiliary device vehicle-mounted, described electrical source of power has the first charging inlet, with
One ground charging device connects；Play a leading role in the feedback braking energy absorbing described drive system simultaneously；
One accumulation power supply, is mainly charged to described electrical source of power by DC/DC changer, supplies to other auxiliary device
Electricity, simultaneously the feedback braking energy of drive system described in assist absorption, participate in powering to drive system；
Described accumulation power supply is provided with the second charging inlet being connected with the second ground charging device；
Under the control of described entire car controller, described accumulation power supply can also realize assisting to described drive system
Power supply；
The capacity of described accumulation power supply is less than the capacity of described electrical source of power.
The reserve of electricity that power supply on vehicle system defined in above technical scheme can make full use of electrical source of power is big, suitable
In the feature powered to slowspeed machine；And accumulation power supply utilizes repeatedly, the high-power charging of short time, maximum
Limit ground obtains foreign aid's electricity, and gradation is auxiliary load supplying or charges in discharge process for electrical source of power, with
Extend after the most exogenous charging of main power source in the way activity duration, and, utilize repeatedly the brachymedial period to main electricity
The activation in source, extends its life-span.It addition, power supply on vehicle system can solve defined in above technical scheme
Existing two power supplys merge the problem working in motor, and at the different voltage platform power supplys merged in using
The problem brought when switching.According to long felt, no matter starting phase or normally travel the phase, it is all with main
Power supply is main load (motor) power supply, thus improves reliability.Accessory power supply be preferably auxiliary load (air-conditioning,
Power-assisted steering, electric inflation pump, blower fan, low-tension supply etc.) power supply, charge remaining as main power source.In braking
In the mode of energy back, in the system of the present invention, acceptable for main power source part is preferentially added to by feedback energy
On main power source (energy type), residue is added on auxiliary power supply (power-type).So main power source obtains suitable little energy
The activation of amount and benefit electricity, service life is longer, and capacity usage ratio is the highest.
The invention has the beneficial effects as follows: power supply on vehicle system of the present invention, increase accumulation power supply, on the one hand an energy
Enough in vehicle traveling process, electrical source of power is persistently charged, be effectively increased the capacity of electrical source of power, can protect simultaneously
Protect electrical source of power and effectively extend the life-span of electrical source of power；On the other hand the characteristic of accumulation power supply can be the biggest
Amount charging, is particularly well-suited to the meeting right place of bus, sanitation cart etc such as and carries out the vehicle of short time stop.
