The positive/negative pulse type intelligent charger is divided into a stabilized voltage supply circuit part, a single-chip microcomputer system circuit part and a positive/negative pulse control circuit part; the stabilized voltage supply circuit part takes electricity from a transformer, and after voltage stabilization, the electricity is provided for a single-chip microcomputer; the single-chip microcomputer and a battery voltage sampling circuit are arranged on the single-chip microcomputer system circuit part; and the positive/negative pulse control circuit receives a charging/discharging control signal of the single-chip microcomputer system circuit part, and transmits electric energy to a battery. Via a series of measures like trickle charging, positive/negative pulse charging, single-chip microcomputer intelligent calculation and the like, charging efficiency is improved, service lifetime of the battery is prolonged, and forced floating time can be easily set.
Description
Technical field
The utility model relates to the charger of electric vehicle, is applicable to the electric bicycle of various brands and model, can the intellectual monitoring charged state, and the protection storage battery, belong to electric motor car charging technique field.
Background technology
Current electric vehicle charger mainly contains following three kinds: 1, three-step charger is about to charging modes and is divided into constant current, constant voltage, floating charge three phases; The syllogic charging modes can meet the needs of the daily charging of electric motor car basically.2, with the charger of anti-reverse and timing function, when the electromobile battery reverse polarity connection, do not charged, prevented fault; Force to transfer floating charge state to after the charging upper limit time reaches, prevent from damaging lead acid accumulator.3, pulse charger, change the constant-voltage phase in three-step charger into the pulse charging mode, do not carry out temperature-compensating, and charging effect has lifting but be undesirable.
Prior art has following shortcoming: 1, three-step charger is the simplest, and cost is also minimum, yet this charging modes has problems, such as each producer's accumulator polarity difference, easily burns out charger; Can not timed and forced floating charge; Easily damage storage battery etc.Although 2, with anti-reverse, with the charger of timing function, can effectively prevent the fault occurred because polarity is different, and can force floating charge, thyristors or the relays of adopting are controlled more, influential or potential safety hazard arranged to electrical network.3, pulse charger has solved the problem of temperature rise aspect in the charging process, and charge efficiency increases simultaneously, but the charging interval can be longer.
The utility model content
In order to overcome the various defects of above-mentioned electric vehicle charger, the utility model provides a kind of positive negative pulse stuffing type Intelligent charger for electric bicycle, it has the intellectuality of height, can automatically according to the oneself state of storage battery, determine charging modes, charging voltage and the charging current of automatically regulating storage battery.
The utility model is that the technical scheme that its technical problem of solution adopts is: positive negative pulse stuffing type Intelligent charger for electric bicycle comprises transformer, the output of transformer is connected with the power input of positive negative pulse stuffing control circuit with the power input of voltage-stabilized power supply circuit respectively, the output of voltage-stabilized power supply circuit is connected with microcontroller system circuit, an output control terminal in microcontroller system circuit is connected with the charging circuit control end in the positive negative pulse stuffing control circuit, another output control terminal in microcontroller system circuit is connected with the discharge circuit control end in the positive negative pulse stuffing control circuit, the positive negative pulse stuffing control circuit is connected with storage battery, described microcontroller system circuit comprises single-chip microcomputer and battery tension sample circuit.
Technique scheme is following technical solution problem, alternating current becomes D.C. regulated power supply after transformer and voltage-stabilized power supply circuit, D.C. regulated power supply provides power supply for microcontroller system circuit, single-chip microcomputer judges whether overdischarge of storage battery by the battery tension sample circuit, for the storage battery of overdischarge, carries out trickle charge; When can bearing large electric current, storage battery enters again the constant current charge of conventional syllogic in the charging stage; Storage battery for not overdischarge carries out conventional constant current charge; Along with cell voltage rises, positive negative pulse stuffing control circuit of the present utility model produces the pulse current charge mode will replace the constant voltage charge of conventional syllogic in the charging stage; At storage battery, be full of after electricity or charging interval reach the floating charge start-up time arranged in single-chip microcomputer, for making up the storage battery self discharge, microcontroller system circuit sends control signal, controls the positive negative pulse stuffing control circuit storage battery is carried out to floating charge.
The control signal that the charging circuit of positive negative pulse stuffing control circuit and discharge circuit are sent by microcontroller system circuit is controlled, according to the charging interval of setting in Single Chip Microcomputer (SCM) program and discharge time, the positive negative pulse stuffing charging modes adopt charge-stop fill-discharge-stop the cyclic process of filling-charging, this charging modes makes and reduces gassing and reduce temperature rise in charging process, extending battery life, improve charge efficiency; The size of charging voltage during charging, determined by the controlled square wave of duty ratio of the output control terminal output of the charging signals of microcontroller system circuit.
The beneficial effects of the utility model are, by series of measures such as trickle charge, positive negative pulse stuffing charging and Intelligent Single-Chip Based computings, have shortened the charging interval, improve charge efficiency, and extending battery life, can arrange easily and force the floating charge time.
