Description
Technical field
The invention belongs to energy resource supply or the complementary technology field of electric vehicle, particularly a kind of isolation trailing type
Wireless power supply and its application in tramcar electric power system and charging system for electric automobile.
Background technology
In recent years, the growing good life of the people needs the contradiction between uneven insufficient development increasingly prominent
Go out, such as in city, people need facility of going on a journey, it is desirable to it is urban, with fresh air, but a large amount of uses of fuel oil private car
Traffic congestion and pollution from exhaust emission are brought again.Alleviate these contradictions need it is multi-pronged, in traffic and energy technology aspect, then
It is to greatly develop public transport and vehicle energy oil changes electricity, all kinds are built in each city according to itself scale and development are expected
Public transport, for example build the subway system of the Urban Underground operation of large conveying quantity, and the street iron run in the street of middle freight volume
System（Tramcar）And at least busy enjoys the bus system of Exclusive Right of Way, wherein tramcar system is because of the city of capacity
Scale strong adaptability, it is environmental using electric energy and increasingly favored by Urban Traffic Planning person.
Known in the industry, tramcar tradition power supply is to be contacted directly with special aerial cable by pantograph in vehicle roof
Access electricity, exposed aerial cable aesthetic property belongs to different people, different views, but the tunnel that has built up of modern city and overpass headroom
May not enough and on street largely mark card holders, the intensive structures such as video monitoring also increase contact net bring it is latent
In danger, partly such as business prosperously, cultural attractions block be even more the presence that can not put up with aerial cable, more typhoon disaster weather
City and have that city contact net damage probability caused by accumulated snow is big, therefore by low-floor and it is handsome in appearance characterized by modern times have
Rail electric car overhead contact line supplier case traditional when rising again is not fond of, generally only exists in such as rolling stock section's indoor maintenance
The suburb in the city that workshop or part weather are adapted to.As alternate modification, the tramcar electric energy acquisition side of current state-of-the-art technology
Formula have precharge energy storage and or sudden strain of a muscle of entering the station fill energy storage pattern, also there is terrestrial segment directly to power or ground induction charging scheme.Enter
Patent " the ground confession of super capacitor energy-storage type tramcar of the energy storage scheme referring to Application No. CN201610630273 is filled in sudden strain of a muscle of standing
Technology disclosed in electric system ", this technology is that vehicle sets adaptation to dodge the battery such as super capacitance cell filled, when electric car enters the station
It will be contacted with the charging contacts for being arranged on station ceiling or vehicle bottom by electrical contact, entered using the of short duration time for the people that stops to receive or discharge passengers
Row electric energy supplements and stored the electric energy for arriving next station enough.Terrestrial segment power taking scheme is referring to Application No.
Surface power supply technology disclosed in CN201310712092 patent " self-insulating Modularized power supply connection ", by supply line
It is each self-insulating and treating to have inside the used time electric part to be arrived to outside isolated insulation using the collector shoe of vehicle bottom to be divided into many sections
The activation of collector shoe upper magnet is arranged on behind position or the module that vehicle bottom is in corresponding to signal control in place is sent using vehicle
Inner body is mobile and is conducted to external metallization conduction, therefore just obtains electric energy with the collector shoe of external metal contact.In addition
Also ground carries out the scheme of wireless charging in trial operation by induction coil：Using magnanimity coil along the square staggered superposition of track
It is disposed to extend, when tramcar passes through and the interactive identification of electric power system signal is to determine which group coil as charge coil, is constantly sentenced
The coil that disconnected and switching is actually charged.
The electric energy supply scheme of above-mentioned electric car has some shortcomings, for example energy supply technology is filled in sudden strain of a muscle of entering the station, because what adaptation sudden strain of a muscle was filled surpasses
Level capacitor type battery energy density is too low, so the low-floor tramcar of kind application typically can be huge multiple in car body top setting
Miscellaneous composite battery group, account for very much volume and tie up payload（Generally weigh hundreds of kilograms）And cause vehicle's center of gravity higher, electricity
What instantaneous super large power consumption when overhead cost and charging are paid in environmental protection when maintenance cost, the battery in pond are eliminated was brought to power network rushes
Super-large current when hitting, charging is with about（Charged in 20 ~ 30 seconds electric currents with up to 1500A ~ 2400A even more highs）Big electricity
High temperature that stream is brought accelerates insulating part aging to be required for extra input and persistence maintenance expense, and road delays too long i.e. between two stations
Summer is set also to disable air-conditioning, or even electric energy exhausts and has to seek roadside assistance, these are all bad Consumer's Experiences；Super large
The electromagnetic field that current strap is come to the baby in the driver and conductor and passenger of this work, pregnant woman for a long time and is mounted with artificial cochlea
Or the health hazards risk that the specific crowd of pacemaker is brought needs prudent management and control, therefore the electric energy supplement mode dodged and filled that enters the station
Bring urban while also bring many challenges；For the terrestrial segment power taking scheme of current techniques, either vehicle
In place magnet attraction or electric signal triggering carry out Partial panel galvanization power supply, collector shoe friction advance bring wear away, conductive mould
The failure risk that labyrinth, the tie point of magnanimity are brought inside block brings higher cost, to Construction Party and operation side's band
Carry out pressure.Current tramcar wireless power technology is brought without other surface power supply technology " conductive channel " abrasion problems,
But because electric car needs to advance at a relatively high speed, the density and implementation cost of coil staggered superposition and charge efficiency direct correlation, sea
The shortcomings that cost and fault rate and not high obvious energy conversion efficiency that amount coil and electric contact are brought.
In electric automobile field, contact charging is to forbid to use outside current main-stream but rainy day room, and this gives people's trip band
It is inconvenient to come, and in addition to the secondary cost bought of battery, electrically-charging equipment is few to be inconvenient to be the more peddling less selling weight of ev industry
Reason is wanted, if but charging pile stands in great numbers and necessarily also extinguished cheerfulness and enthusiasm in each parking lot.Therefore outer the stops establishment wireless charging facility indoors,
Make full use of vehicle guard station down time, it is not necessary to deliberately operation plug charging plug, it is round-the-clock to open the wireless of charging
Charge mode is the most basic form of following electric car electric energy supplement；And to periphery electromagnetic environmental impact minimum, charge efficiency
Highest wireless charging scheme is the electricity reception coil in each parking stall vehicle bottom with being arranged at the charge coil on ground closely
Face, current techniques will need to rely on vehicle up to this mesh and move face repeatedly, or move movable " charging pad " and remove face vehicle
Electricity reception coil, this experience can not actually promote.To solve this problem, as patent No. CN201580064426- " is used to run
Electric energy induction type is transferred to the method and system of the charging station of the vehicle with accumulator " disclosed one kind wishes that vehicle is big
A series of method for causing to stop to adjust by the coil and electronics that set redundancy afterwards in place is led to obtain " more rational charge position "
The complexity of coil and circuit is caused and has wasted.
