Description
Technical field
The present invention relates to the aerator field, specifically, relate to a kind of intelligence and repair Charging Instrument.
Background technology
Charger is a kind of equipment that alternating current is converted to low-voltage DC.Mainly there is following deficiency in charger commonly used at present, lacks the battery repair function, because the ambient temperature difference forms the phenomenon that overcharges or owe to fill through regular meeting to battery, also has the lower shortcoming of energy conversion efficiency.
Summary of the invention
The purpose of this invention is to provide and a kind ofly have battery repair function, energy conversion efficiency height, and the intelligence that can prevent to owe to fill and overcharge phenomenon is repaired Charging Instrument.
The technical scheme that realizes above-mentioned purpose is: a kind of intelligence is repaired Charging Instrument; comprise battery pack; also comprise single-chip microcomputer; auxiliary power; full-bridge DC/DC converter; restoration switch; thermistor; voltage and current sampling circuit; relay output protection circuit and nixie display are formed; auxiliary power provides power supply for single-chip microcomputer; the output of single-chip microcomputer is electrically connected with the input of full-bridge DC/DC converter and relay output protection circuit respectively; the output of full-bridge DC/DC converter is electrically connected with the input of relay output protection circuit; restoration switch is connected with 9 pin of single-chip microcomputer; voltage is connected with 2 pin with 1 pin of single-chip microcomputer with current sampling circuit; thermistor is connected with 18 pin of single-chip microcomputer; pwm control circuit is connected with 13 pin of single-chip microcomputer; the output of single-chip microcomputer also is electrically connected with nixie display; the output of relay output protection circuit is electrically connected with voltage and current sampling circuit, and another output on the relay output protection circuit connects battery pack.
After adopting technique scheme, be connected with restoration switch on the single-chip microcomputer, whether connection by switch can determine whether to enable the battery repair function, owing to be connected with thermistor on the single-chip microcomputer, single-chip microcomputer is converted into temperature by the voltage that detects on the thermistor, thereby according to the charging voltage (the temperature high voltage is low, temperature low-voltage height) of temperature automatic setting battery, thus can prevent that single voltage charging instrument from causing because the environment difference overcharges or owes to fill phenomenon to what battery formed.Owing to adopted full-bridge DC/DC converter, and adopted Single-chip Controlling, improved the energy conversion efficiency of Charging Instrument greatly, can reach about 87%, can save the energy of a large amount of electricity charge and maintenance for the user.

Embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
Shown in Fig. 1 ~ 4; a kind of intelligence is repaired Charging Instrument; comprise battery pack; also comprise single-chip microcomputer; auxiliary power; full-bridge DC/DC converter; restoration switch; thermistor; voltage and current sampling circuit; relay output protection circuit and nixie display are formed; auxiliary power provides power supply for single-chip microcomputer; the output of single-chip microcomputer is electrically connected with the input of full-bridge DC/DC converter and relay output protection circuit respectively; the output of full-bridge DC/DC converter is electrically connected with the input of relay output protection circuit; restoration switch is connected with 9 pin of single-chip microcomputer; voltage is connected with 2 pin with 1 pin of single-chip microcomputer with current sampling circuit; thermistor is connected with 18 pin of single-chip microcomputer; the output of single-chip microcomputer also is electrically connected with nixie display; the output of relay output protection circuit is electrically connected with voltage and current sampling circuit, and another output on the relay output protection circuit connects battery pack.The model of single-chip microcomputer is EM78P259.
Operation principle of the present invention is as follows:
The battery repair function: connect 9 pin of single-chip microcomputer by a restoration switch, whether the connection by switch determines whether to enable the battery repair function.(repair function: after judging abundance, the red led on the Charging Instrument can not convert blue lamp to, but keep certain electric current battery is repaired charging).
Temperature sampling: 18 pin that connect single-chip microcomputer by thermistor, single-chip microcomputer is converted into temperature by the voltage that detects on the thermistor, thereby (the temperature high voltage is low according to the charging voltage of temperature automatic setting battery, temperature low-voltage height), can prevent that single voltage charging instrument from causing because the environment difference overcharges or owes to fill phenomenon to what battery formed.
PWM control: 13 pin output pwm signals by single-chip microcomputer go to control charging current, make charging current more accurate.
Electric current and voltage detects: cell voltage is added to 1 pin of single-chip microcomputer by electric resistance partial pressure, and current signal is by putting 2 pin that are added to single-chip microcomputer after fortune LM358-2 amplifies; When single-chip microcomputer detects that 1 pin has positive voltage and drives the relay adhesive to battery charge in normal range (NR) the time, begin simultaneously to carry out that charging current detects and show current cell voltage and charging current and charged state (red light is bright) on charactron; If detect less than charging current or current/voltage, relay disconnects, with protection Charging Instrument and battery pack.In charging process, regularly turn-off output, so that accurately measure cell voltage.
Detection is finished in charging: adopt state-of-the-art negative deltaV method, and the actual conditions of voltage and current cooperate PWM to control to guarantee the battery can be sufficient and don't overcharge.(after judging abundance, the Charging Instrument indicator light is transformed into blue lamp by red, and charging current diminishes, and safeguards charging.）
