Abstract
The invention discloses a kind of alternating-current charging pile charge control methods, opened loop control is carried out to charging pile output electric current, pass through the method for size duty ratio cycle alternation, regulate and control charging pile and exports electric current, large current charge for a period of time after, the charging for carrying out one section of smaller current, loops back and forth like this, and avoids pipette tips from generating heat because of high current accumulation work and jumps rifle.The present invention is alternately controlled by size duty ratio, in the case where neither reducing peak charging current nor significantly reducing mean charging current, alternating-current charging pile fever is effectively reduced and jumps rifle probability, it is ensured that charging pile safe and stable operation.
Description
Technical field
The present invention relates to electric vehicle charging technique field, specifically a kind of alternating-current charging pile charge control method.
Background technique
In recent years, with the development of new-energy automobile and its mating industry, Quantity is continuous throughout the country for charging pile
Increase, following some technical problems also gradually expose.Alternating-current charging pile by duty ratio due to only regulating and controlling charging electricity
Stream, and the corresponding 63A charging gun platform design capacity of national standard is insufficient, contact surface is small to be caused to be easy fever, and has therefore been caused a lot of
Accident.The pipette tips of some producer's productions joined temperature control control switch for safety grounds, and this measure cannot technically solve to send out
Heat problem instead results in frequent jump rifle event.
Summary of the invention
The purpose of the present invention is to provide a kind of alternating-current charging pile charge control methods, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the present invention provides the following technical solutions：
A kind of alternating-current charging pile charge control method, includes the following steps：
S101, when starting is charged, with big space rate D1 control high current I1 to charging batteries of electric automobile, and it is certain to continue charging
Duration th；
After S102, th, switches to small duty ratio D2 and control small charging current I2, the duration tl for charging certain；
S103 judges whether battery of electric vehicle is fully charged, if battery capacity underfill, returns to step S101, if electric vehicle is electric
Pond is fully charged, then terminates to charge.
As a further solution of the present invention：Big space rate D1 >=0.87,10min≤th≤20min.
As a further solution of the present invention：0.85 < D2 < D1, and tl≤th.
As a further solution of the present invention：Tl+th=T, D1=th/T, D2=tl/T, the T value of each circulation are steady state value
Or decrement value.
Compared with prior art, the beneficial effects of the invention are as follows：Present invention employs variable duty cycles to regulate and control charging current side
Case is alternately regulated and controled, opened loop control by size duty ratio D1, D2, without detecting pipette tips end temperature feedback signal, directly with charging
Stake control program calling and controlling size duty ratio D1, D2, by the control of alternately duration, is come to control different charging currents I1, I2
Control charging pipette tips temperature rise occurs to reduce and jump rifle event.
Detailed description of the invention
Fig. 1 is logic timing figure of the invention.
Fig. 2 is flow chart of the method for the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1~2 are please referred to, a kind of alternating-current charging pile charge control method includes the following steps：
S101, when starting is charged, with big space rate D1 control high current I1 to charging batteries of electric automobile, and it is certain to continue charging
Duration th, wherein big space rate D1 >=0.87, it is sufficiently high to control charging current peak value, meet customer need, 10min≤
th≤20min；
After S102, th, switches to small duty ratio D2 and control small charging current I2, the duration tl for charging certain, 0.85
The small duty ratio D2 < D1 of <, and tl≤th, I2 < I1；
Whether fully charged S103 judges battery of electric vehicle, if not having, repeatedly step S101 and S102, until battery of electric vehicle
It is fully charged, terminate.
The T value of tl+th=T, D1=th/T, D2=tl/T, each circulation can be steady state value, can also gradually successively decrease.
The present invention is with open loop control mode, without detecting pipette tips end temperature feedback signal, directly controls program with charging pile
Regulate and control size duty ratio D1, D2, to control different charging currents I1, I2, achievees the effect that control charging pipette tips temperature rise.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter

Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
