Charging system.
Background technique
With becoming increasingly conspicuous for energy and environmental problem, the development of new-energy automobile receives more and more attention.For
Response environment problem, realizes the demand of energy-saving and emission-reduction, China starts to greatly develop electric car.Recently as new energy vapour
The ownership of vehicle continues to increase, and charging problems also receive more and more extensive attention.
The charging modes of electric car are broadly divided into two kinds: conduction-type charges and wireless charging.Conduction-type charging is also referred to as
Wired charging, basic thought are that electricity is taken from unidirectional or three-phase alternating-current supply or power grid, and alternating current is changed into directly by rectified device
Then galvanic electricity gives the power battery charging of electric car.Using machinery between charging gun and the charging equipment of electric car
It is connected, AC charging and DC charging can be divided into according to the charging of the different conduction-types of rectifier position, as depicted in figs. 1 and 2.
AC charging and DC charging are inherently wired chargings, because wired charging is using mechanical connection, institute
Inevitably there is mechanical friction between its charging interface, poor contact is caused, generates electric spark；Simultaneously interface it
Between the problems such as will appear infiltration, there are the security risks such as electric leakage.And these problems are not present in wireless charging technology.

Position, and then driver is prompted to realize positioning.Third is that using servo position control mechanism, it is mobile according to obtained location information
Charge coil realizes contraposition.
Wireless charging and its major defect of coil alignment technology are as follows:
1, existing wireless charging technology is mainly by the way of loose coupling, and charge efficiency is by the position of coil and apart from shadow
Sound is larger.And vehicle will necessarily have certain deviation in practical parking period, coil can not be aligned completely, meeting between coil
Certain dislocation is generated, if dislocation is more serious, charging may be cannot achieve.
2, using the Automatic Alignment System of camera, parking stall graticule is needed for camera to be installed on the outside of vehicle body and detect,
Need to carry out targeted design, and the interference vulnerable to ambient according to vehicle.
3, the system that function is automatically aligned to using coil, it is desirable that vehicle has automatic parking function or pacifies at charge coil
Servo position control mechanism is filled, not only will increase cost in this way, the presence of servo mechanism can also reduce the chassis space of vehicle.
4, using laser as signal emitting-source, the coil alignment system of position sensor can only obtain location information, no
The function of having auxiliary foreign matter and being detection.
