Description
Technical field
The invention belongs to wireless charging technical field, more particularly it relates to a kind of Electric Transit station console hangs
Hanging wireless charging system, can carry out short time high-power wireless charging to the electric bus resting in platform.
Technical background
Along with the aggravation of global warming, energy-saving and emission-reduction have had become as whole world focus of attention problem, traditional
Fuel power public transport cannot meet the needs of energy-saving and emission-reduction, and electrodynamic type new forms of energy bus can be greatly reduced discharge very
To realizing zero-emission, not only improve energy-saving and emission-reduction, also can effectively cut operating costs, it has also become the optimum selection of public transit system,
There is huge development potentiality at home.According to the relevent statistics, China's each bus daily travel about 220-280 kilometer, disappear
Consumption fuel oil about 90-120 liter, is equivalent to oil consumption and the discharge of 30 private cars, if using electric motor car, carbon dioxide discharge-reduction is 44
About Dun.Additionally, electric motor car uses motor to replace electromotor, almost without noise, advantageously reduce the noise pollution in city.
Existing electric bus uses lithium ion battery substantially.Lithium ion battery have safe and reliable, running voltage is high,
The advantages such as memory-less effect, but its energy density is the most relatively low, causes electric motor car single charge continual mileage shorter, in order to reach public
Handing over the vehicle line that car is longer, generally require large-capacity battery pack, weight typically at about one ton, greatly reduces public transport garage
Sail efficiency.The more important thing is that battery cycle life in groups is the most relatively low, cycle life is at about 1000 times.
The charging of existing electric bus is basic uses wired charging, is divided into trickle charge and fills two ways soon.Trickle charge side
Formula needs Public Transit Bus Stopping to charge for a long time at bus charging station.In order to fill every day once electricity meet distance travelled want
Ask it is necessary at least load 220 kilowatt hours, the battery of about 3100 kilograms.For few packed battery, alleviate car body weight, arise that
In some demonstrative projects, two cars is when an automobile-used phenomenon, and namely two cars runs for one day in shifts, and common limited charging
The quantity stood is as the quantity of electric bus to be increased and increases, and needs to take substantial amounts of urban land.Fast charge mode by
Very big in the charging current of demand, charger opened by a charging station, and power, it is possible to reach " megawatt " level, needs training special
Operator, increase charging cost, additionally charging operations is the most abnormally dangerous.Put completely further, since set of cells is substantially at
Electricity condition, can shorten the life-span of lithium battery.
Wireless charging, also referred to as induction charging, be to utilize near field to sense, namely inductive, by power supply unit (charging
Device) transmit its energy to the device of electricity consumption, this device uses the energy received to charge battery, and operates for itself simultaneously
It is used.Owing to transmitting energy with inductive between charger and power device, do not run wires to, therefore charge
The device of device and electricity consumption can be accomplished to expose without conductive junction point, safety more more convenient than wired charging.Secondly, carry out wireless
Charging is automatic charging, it is not necessary to operator, can avoid the danger got an electric shock.Again, wireless charging electrical equipment without exposing,
Will not be corroded by the moisture in air, oxygen etc.；Contactless existence, also thus without having at the mechanical mill connected and when separating
Undermine the loss that arcing etc. is made.
But, the major part of vicarious wireless charger is transmitting coil and receiving coil.Launch and receiving coil it
Between have the biggest air gap, the generally equivalent to public transport vehicle chassis distance to ground, size of gaps is the loosely coupled transformer coefficient of coup
One of key factor.In order to reach the charge power of amount, need to increase the electric current in transmitting coil, thus the spoke of electromagnetic field
Penetrate increase.Electromagnetic field, as the energy transmission medium of vicarious wireless charging system, can produce whirlpool to ground metal
Stream effect, directly heats metal, has the risk of fire.The most a piece of masking foil drops under automobile chassis, high-power
The magnetic field that wireless charging system produces produces rapidly big electric current on tinfoil paper, and ignite masking foil.In order to eliminate the gold fallen to the ground
Belonging to the disaster hidden-trouble that (such as coin, chewing gum packing paper, pop can etc.) brings, induction wireless charging system is usual
Metal detection device can be equipped with, considerably increase design cost.Electric automobile use high frequency electromagnetic wave to tissue with
And nervus centralis all has injury.International unionized radio protective committee International Commission on Non-
Ionizing Radiation Protection (ICNIRP) has strict rule to human body in high-frequency electromagnetic radiant intensity after the match
Fixed.For high-power electric bus wireless charging, need to shield with metallic plate.But due to underbody limited space, no
It is beneficial to the design of shielding harness.In addition electromagnetic field of high frequency for charging time be positioned at the toy under chassis, such as cat, Canis familiaris L., Serpentis etc.,
There is fatal harm especially.It addition, wireless charging can not solve electric bus to the demand of large-capacity battery pack and battery
The problem that life-span is short.
In sum, electric bus charging shortcoming includes: 1. battery volume weight is big, reduces bus running efficiency.
2. battery life is shorter.For the wireless charging of electric bus, its shortcoming includes: 1. the transmission range on identity distance chassis is big,
Efficiency of transmission is relatively low；2. ground metal object has disaster hidden-trouble；3. needing individually designed metal detection device, cost is high；4.
Underbody limited space, the shielding harness design difficulty of electromagnetic field increases.
Summary of the invention
For overcoming above-mentioned electric bus charging shortcoming and the shortcoming of electric bus wireless charging, the present invention proposes one
