Description
Technical field
The invention belongs to wireless charging technical fields, more particularly it relates to which a kind of Electric Transit station console is outstanding
Hanging wireless charging system can carry out the charging of short time high-power wireless to the electric bus for resting in platform.
Technical background
With the aggravation of global warming, energy-saving and emission-reduction have become whole world focus of attention problem, traditional
Fuel power public transport can no longer meet the needs of energy-saving and emission-reduction, and discharge can be greatly reduced very in electrodynamic type new energy bus
To zero-emission is realized, energy-saving and emission-reduction are not only improved, operation cost can also be effectively reduced, it has also become the optimal selection of public transit system,
There is huge development potentiality at home.According to the relevent statistics, about 220-280 kilometers of each bus daily travel of China, disappears
Fuel oil about 90-120 liter is consumed, the oil consumption and discharge of 30 private cars are equivalent to, if using electric vehicle, carbon dioxide discharge-reduction 44
Ton or so.In addition, electric vehicle replaces engine using motor, almost noiseless, advantageously reduces the noise pollution in city.
Existing electric bus uses lithium ion battery substantially.Lithium ion battery have safe and reliable, operating voltage is high,
The advantages that memory-less effect, but its energy density is still lower, causes electric vehicle single charge continual mileage shorter, it is public in order to reach
The longer vehicle line of vehicle is handed over, generally requires large-capacity battery pack, weight generally at one ton or so, greatly reduces public transport garage
Sail efficiency.More importantly battery group cycle life is generally lower, and cycle life is at 1000 times or so.
Existing electric bus charging is charged using wired substantially, is divided into trickle charge and fast charge two ways.Trickle charge side
Formula needs Public Transit Bus Stopping to carry out long-time charging in bus charging station.Meet mileage travelled to fill primary electricity daily to want
It asks it is necessary at least load the battery of 220 kilowatt hours, about 3100 kilograms.For few packed battery, mitigates car body weight, just will appear
Two cars are when an automobile-used phenomenon in some demonstrative projects, that is, run in shifts for two cars one day, and common limited charging
The quantity stood is increased as the quantity of electric bus increases, and needs to occupy a large amount of urban land.Fast charge mode by
Very big in the charging current of demand, a charging station opens charger, and power may reach " megawatt " grade, needs training special
Operator, increase charging cost, in addition charging operations are also abnormally dangerous.In addition, being put completely since battery pack is substantially at
Electricity condition can shorten the service life of lithium battery.
Wireless charging, also referred to as induction charging are using near-field sensing, that is, inductive coupling, by power supply unit (charging
Device) device of electricity consumption is transmitted its energy to, which charges to battery using the energy received, and operates simultaneously for itself
It is used.Due to transmitting energy between charger and power device with inductive coupling, do not run wires between the two, therefore charge
Device and the device of electricity consumption can accomplish that no conductive junction point is exposed, safety more more convenient than wired charging.Secondly, carrying out wireless
Charging is automatic charging, does not need operator, can be avoided the risk of electric shock.Again, wireless charging electrical component is without exposed,
It will not be eroded by the water and oxygen in the air；The presence of contactless also therefore not has mechanical mill when connecting and separating
Undermine the loss that arcing etc. is made into.
But the major part of induction type wireless charger is transmitting coil and receiving coil.Transmitting and receiving coil it
Between have very big air gap, the generally equivalent to distance of public transport vehicle chassis 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.Energy transmission medium of the electromagnetic field as induction type wireless charging system can generate whirlpool to the metal on ground
Effect is flowed, metal is directly heated, the risk with fire.Such as a piece of masking foil is fallen under automobile chassis, it is high-power
The magnetic field that wireless charging system generates generates rapidly high current on tinfoil paper, and ignite masking foil.In order to eliminate the gold to fall to the ground
Belong to (such as coin, chewing gum packing paper, pop can etc.) bring fire hazard, induction wireless charging system is usual
It can be equipped with metal detection device, considerably increase design cost.The electromagnetic wave for the high frequency that electric car uses to tissue with
And nervous centralis has injury.International unionized radio protective committee International Commission on Non-
Ionizing Radiation Protection (ICNIRP) has stringent rule in the radiation intensity of high-frequency electromagnetic off field to human body
It is fixed.For high-power electric bus wireless charging, need to be shielded with metal plate.But since vehicle base space is limited, no
Conducive to the design of shielding harness.Furthermore toy when electromagnetic field of high frequency is for charging under chassis, such as cat, dog, snake etc.,
Even more there is fatal harm.In addition, wireless charging not can solve demand and battery of the electric bus to large-capacity battery pack
Service life short problem.
In conclusion electric bus charging disadvantage includes: that 1. battery volume weights are big, bus running efficiency is reduced.
2. battery life is shorter.For the wireless charging of electric bus, disadvantage includes: that the transmission range on 1. ground identity distance chassis is big,
Efficiency of transmission is lower；2. ground metal object has fire hazard；3. individually designed metal detection device is needed, it is at high cost；4.
Vehicle base space is limited, and the shielding harness design difficulty of electromagnetic field increases.
