The pin P1.4 of the single-chip microcomputer is used for detecting floating charge signals transmitted from the floating charge light emitting diode of the charger through an optical coupler, once the pin P1.4 detects a floating charge signal, floating charge timing is started after 15 seconds when then floating charge signal can still be detected, and after 2-hour floating charge, the pin P1.7 of the single-chip microcomputer is disconnected from the 220 v commercial power of the charger through the optical silicon controlled rectifier and the silicon controlled rectifier. The intelligent charger controller has the advantages that the circuit design is simple, the charging device can be controlled, charging can be performed safely and effectively, the damage of the battery due to over charging can be avoided, and the electric energy is also greatly saved.

Description

The electric car charger intelligent controller

Technical field:

The utility model relates to automatic control equipment, relates in particular to the electric car charger intelligent controller.

Background technology:

Commercially available charger charges to secondary cell now, on the one hand on the pole plate of storage battery, can produce accumulation because of current density excessive, the acid strength difference is increased relatively and produce polarization and react, accumulator plate is passivated, and reduce the respond of pole plate step by step, directly have influence on the charging and discharging capabilities of battery, and the internal resistance of pole plate is increased, influence the cycle charge-discharge effective degree of battery, shorten the useful life of battery.Especially now just be in the operating state of charging after the commercially available charging device energized, although there is a charger to add the trickle circuit, to being protected to some extent towards battery, the circuit of charging still is in the state of work always, and its power consumption remains considerable waste.Charger charged 2 hours by 100 watts of calculating every day more, with 1 degree electricity, with more than 70 degree electricity, wasted surprising more than 1 year more than 5 days.

The utility model content:

The purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of electric car charger intelligent controller is provided, can control charging device safety and charging effectively, can disconnect AC power by light-operated silicon control controllable silicon, charger is quit work, prevent to prolong the useful life of battery because of overcharging the damage battery.

Electric car charger intelligent controller described in the utility model, 220 volts of civil powers are exported the power supply of 5 volts of direct currents as each element through 1 step-down of resistance R 1 capacitor C through bridge rectifier D1 rectification, capacitor C 2 filtering, voltage-stabiliser tube D2 voltage stabilizing.The light-emitting diode DS1 that the P1.3 pin of single-chip microcomputer connects after the energized is bright, press the button S1 that is connected with the P1.6 pin of single-chip microcomputer, the electric motor intelligent controller is started working, light-emitting diode DS1 is every light on and off in 1 second 1 time, the P1.5 pin of single-chip microcomputer is controlled through light-operated silicon, and controllable silicon is connected 220 volts of line chargers of charger and started working.The P1.4 pin of single-chip microcomputer detects the floating charge signal that is sent through the light idol by charger floating charge light-emitting diode at any time, in a single day the P1.4 pin detects the floating charge signal, still can detect floating charge signal floating charge timing after 15 seconds begins, light-emitting diode DS1 is every light on and off in 4 seconds 1 time, the P1.7 pin of floating charge single-chip microcomputer after 2 hours is through light-operated silicon, controllable silicon disconnects 220 volts of civil powers of charger, at this moment light-emitting diode DS1 Chang Liang, standby power has only=0.357 watt of 0.07X1 microfarad X5.1 volt, can avoid overcharge of a battery like this, prolong the useful life of storage battery, can also saves energy.

When connecting 220 volts civil powers by software programming, the pulsating voltage when avoiding plug insertion socket in 3 seconds of delay time, detection floating charge signal begin the floating charge timing after 15 seconds can prevent the false floating charge signal that causes owing to malfunction or external interference like this.There is the serial ports memory to be connected to P3.0, the P3.1 pin of single-chip microcomputer in the electric motor intelligent controller, the data power down of storage can be preserved 100 years, memory cell can be carried out write operation 1,000,000 times, charger has a power failure in charging process, can write down the state before charger has a power failure automatically, be in constant current, constant voltage, or floating charge state.If floating charge state, floating charge how long also floating residue how long, timing floating charge of remaining time of floating charge when having a power failure during incoming call, be in after charging finishes the holding state intelligent controller note automatically this state in the middle of this no matter how long no matter the incoming call how many times charger that has a power failure does not recharge.Do not bring into use storage battery if charging finishes to pull out attaching plug, the electric weight that detects 15 seconds storage batterys when recharge next time does not earlier reach floating charge state and begins charging from constant current, constant voltage.

Operation principle of the present utility model: after the charger energized, indicator light LED0 is bright, delays time three seconds, after waiting to stablize, the bright flicker of going out 1 second in 1 second of indicator light LED0, single-chip microcomputer P1.4 pin output low level, by the conducting of light-operated silicon MOC3023 control controllable silicon, charger is normally started working.When charger begins floating charge, single-chip microcomputer P1.3 pin detects charger floating charge signal, the single-chip microcomputer timing begins, the best floating charge time that the utility model is set is 2 hours, after 2 hours, and single-chip microcomputer P1.4 pin output high level, disconnect the 220V alternating current by light-operated silicon MOC3023 control controllable silicon, charger quits work, and prevents to overcharge the damage battery, prolongs battery useful life.

When single-chip microcomputer P1.3 pin detects charger floating charge signal, misoperation occurs, adopt three detections, delayed time five seconds at every turn, after confirming at last to produce the floating charge signal really, just begin the floating charge timing in order to prevent external interference.In order to prevent to have a power failure in the charging process, the user who has goes on business several days after filling electricity with, even a week, battery may be filled badly first, has second caused a large amount of energy wastes.Controller tape storage M24C02 of the present utility model can preserve the running status before having a power failure after the power failure, the state before can recovering automatically behind the incoming call to send a telegram here is constant current, constant voltage charge or floating charge that is:, if floating charge, how much floating charge time also has.

Electric car charger intelligent controller described in the utility model, circuit design is simple, can control charging device safety and charging effectively, can disconnect AC power by light-operated silicon control controllable silicon, charger is quit work, prevent to prolong the useful life of battery, also can save electric energy in large quantities because of overcharging the damage battery.
