The present invention is described in further details with reference to the accompanying drawing.
Wireless charging Wireless Power Transfer, abbreviation WPT, referring to Fig. 1, wireless charging system is by ground
Component Ground Assembly and vehicle assembly Vehicle Assembly composition, terrestrial components Ground Assembly and vehicle
Component Vehicle Assembly distinguishes abbreviation GA and VA, and wireless charging WPT system can be by the energy transfer of power grid to vehicle
, to realize wireless charging function, wireless charging can be applied not only to kart shown in FIG. 1, moreover it is possible to be widely applied
In other electrified vehicles, such as bus, rail vehicle, steamer, aircraft etc..
The terrestrial components GA of wireless charging WPT system includes power factor corrector, inverter, filter, GA coil etc.,
Vehicle assembly VA includes filter, VA coil, rectifier, impedance transducer, Vehicular battery etc., please refers to Fig. 2 (partial circuit group
Part is not shown), Vehicular battery generates voltage and current appropriate and powers to vehicle, wherein being coupled to by the magnetic energy that GA coil generates
VA coil, thus realize power grid to vehicle energy transfer, it is important that GA determine have the vehicle of compatible VA in place and
Before appropriate preparatory condition, wireless charging WPT system does not start energy transfer.Wireless charging WPT system is passing through necessity
Safety and compliance check after, then carry out closed loop charging operations it is as follows:
A. wireless charging WPT system determines the electric current for needing to charge to battery in VA.
B. channel from VA is transmitted to GA by wireless communication for energy request.
C. GA identification request, electric power is extracted from power grid, sends it to GA coil.
D. GA coil is coupled to VA coil, is rectified and is handled in VA, and charges to battery.
E. it persistently carries out, until VA issues different energy level requests, the request including not needing energy.
Vehicle assembly VA is generally positioned at vehicle interior, referring to Fig. 3, the vehicle assembly of wireless charging WPT system VA
It sets in the middle part of vehicle, in this embodiment, the vehicle assembly VA in the middle part of vehicle receives the electric energy from power grid, is worth
It is noted that in other embodiments, the position vehicle assembly VA of wireless charging WPT system is also in front of vehicle,
Side, the position of vehicle assembly VA is mainly convenient convenient in a reasonable position and terrestrial components GA cooperation, so that vehicle
Electric energy can be obtained from power grid rapidly.
Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8 are please referred to, wireless charging WPT is to couple by magnetic energy by the energy in GA coil
It is transferred to VA coil, a changing magnetic field is generated in GA coil, changing magnetic field is converted to electricity by coupling by VA coil
Stream, the coil diameter coil diameter D of GA coil and VA coil may be different in actual conditions, GA coil and VA coil it
Between coil distance coil distance Z can also change.Due to the coil distance coil between GA coil and VA coil
Distance Z is different, and the magnetic field that only some GA coil generates can be absorbed by VA coil and be converted into electric energy.Entire
In the process, the magnetic flux that VA coil receives is bigger, then two coil couplings are better.As shown in figure 4, working as transmission coil system
600 is identical with 700 size of receiving coil system, and when the distance between coil is far smaller than coil diameter, will generate tight
Coupling, coupling is higher, and the efficiency that energy is transmitted between coil is higher, and can reduce the fever of leakage field and coil.As Fig. 5,
Shown in Fig. 6, when transmission coil system 600 and 700 size of receiving coil system have obvious gap or apart from it is far when, can generate
Loose coupling loosely coupled, in loosely coupled system, only fraction changing magnetic field can be received coil reception, this
It means that loosely coupled system can generate more electromagnetic leakages, therefore is not suitable for the applied field to EMI and EMF high request
Scape.
In tightly coupled system, since energy transmission is more efficient, generation heat is less, is suitble to require fever control
Higher equipment can also generate the small angle inclination of plane, as shown in Figure 7 between actual GA coil and VA coil.Actual GA
Relative rotation, dislocation can be also generated between coil and VA coil, as shown in Figure 8.Incline between GA coil and VA coil with angle
It tiltedly and situations such as rotary shifted is also the charged state that actual wireless charging process may occur.In actual wireless charging mistake
Cheng Zhong needs to carry out the calibration between GA coil and VA coil, keeps the electric energy transmission efficiency of its wireless charging WPT system optimal,
Actual offset of the coil calibration including x, y, Z-direction further includes x, y, Z-direction other than the offset calibration in X, Y and Z
The calibration of rotational misalignment, rolling are vehicles around the rotation of × axis, and pitching is rotation of the vehicle around Y-axis, and sideway is vehicle around × axis
Rotation.Generally GA coil can also be known as transmitting coil, VA coil is known as receiving coil, it can be convenient for preferably reason
Solution.
It is optimal the electric energy transmission efficiency of wireless charging WPT system, it is necessary to the transmitting to wireless charging WPT system
The energy transmission parameter of opposite position state is tested between coil system 600 and receiving coil system 700, is mainly had vertical
Straight distance change, the back and forth or left and right direction offset of horizontal direction, the deflection of vehicle body axis, body sway practical charging situation,
That is the wireless charging WPT system offset, inclination and the rotation position state that at least need to have X, Y, Z axis direction, could be closer to
Actual positional relationship during wireless charging between transmission coil system 600 and receiving coil system 700, relative to practical vehicle
Various charged states when carrying out wireless charging, it is also necessary to the various combined type location status between former-wound coil, thus
Test parameters of the vehicle when actual wireless charges.
How the service conditions such as physical location variation are simulated in testing to evaluate the performance of charging system and just fill to test
More stringent requirements are proposed for the design set, in order to solve it is in the prior art cannot completely simulating vehicle charging when receiving coil
Transmitting electric coil between change in location the problem of, mainly can not achieve vertical range variation, horizontal direction front and back or
Left and right directions deviates, vehicle body axis deflects, the actual conditions of body sway, and the present invention provides a kind of chargings of high-power wireless to survey
