Description
Technical field
The present invention relates to a kind of intelligent charger, particularly relate to a kind of intelligent charger that lead acid accumulator is charged.
Background technology
Electric motor car itself does not discharge pernicious gas air being had to pollution, less relative to orthodox car to environmental impact, and its prospect is extensively had an optimistic view of, and obtains the favor of people.Electric motor car uses lead acid accumulator as power resources, this lead acid accumulator have good invertibity, voltage characteristic steadily, the advantage such as long service life.But find through market survey, do not reach the useful life of design the useful life of existing lead acid accumulator, reason is that the charger of existing lead acid accumulator has a serious impact the useful life to lead acid accumulator.At present, the charger charging method of conventional lead acid accumulator comprises: constant current charge method, constant voltage charge method, two-stage mise-a-la-masse method and pulsation mise-a-la-masse method.When adopting constant voltage charge method, because lead acid accumulator voltage loss is many, at the charging initial stage, voltage difference between lead acid accumulator and charger is larger, make charging current also larger, thus causing lead acid battery charge too fast, battery generates heat in a large number so that swelling appears in lead acid accumulator, and then has had a strong impact on the useful life of lead acid accumulator.When adopting constant current charge method, lead acid battery charge initial stage and latter stage of charging are all charge with constant electric current.Phase after charging, due to the rising of lead acid accumulator electromotive force, big current is used to charge with regard to not needing.If continue to adopt big current to charge, the unnecessary electricity of constant current charge will be used to electrolyte, makes the two poles of the earth of lead acid accumulator produce bubble.Long-Time Service will make the electrolyte of lead acid accumulator tail off, and solidification phenomenon appears in the two poles of the earth, thus reduces the useful life of lead acid accumulator.Two-stage mise-a-la-masse method combines constant current charge method and constant voltage charge method, use early stage use constant voltage charge method to charge to lead acid accumulator in constant current charge method later stage, this kind of granting is better than above-mentioned two kinds of methods, but the conversion between charging modes is wayward, and the storage battery of initial charge storage battery and Long-Time Service should not be used for.Pulsation mise-a-la-masse method more can extend the useful life of storage battery than aforementioned three kinds of methods, but the charging interval is long, and charge efficiency is not high.
In view of the above problems, be necessary to provide a kind of intelligent charger, to solve the problem.
Summary of the invention
For the deficiencies in the prior art, the technical problem that the present invention solves is to provide a kind of intelligent charger, this intelligent charger also switches charging modes accordingly by the magnitude of voltage and current value detecting battery to be charged, improve charge efficiency, extend battery, improve battery safety in utilization.
In order to solve the problems of the technologies described above, technical scheme of the present invention is achieved in that
A kind of intelligent charger, the detection module comprising charging module, the control module be connected with described charging module and be connected with described control module, described charging module comprises constant-current charging circuit, pulsation charging circuit and trickle charging circuit, described constant-current charging circuit, pulsation charging circuit and trickle charging circuit control by described control module, described detection module comprises voltage detection module and current detection module, and the magnitude of voltage detected and current value are transferred to described control module by described voltage detection module and described current detection module.
Further, described control module is single-chip microcomputer.
Further, described voltage detection module is voltage sensor.
Further, described current detection module is current sensor.
The invention has the beneficial effects as follows: compared to prior art, intelligent charger of the present invention also switches charging modes accordingly by the magnitude of voltage and current value detecting battery to be charged, improve charge efficiency, extend battery, improve battery safety in utilization.
Accompanying drawing explanation
Fig. 1 is the module diagram of intelligent charger of the present invention.
