Description

A kind of quick charge device

Technical field

The present invention relates to a kind of quick charge device, belong to charging method and charging device class.

Background technology

Commercially available chewing gum battery charger, it is design according to the capacitance of different batteries and respectively, divide with the charging current size, general with " 10 multiplying power " of battery capacity 10% as the charging current size, then need charge about 15 hours, with the value of battery capacity 30% " 30 multiplying power ", then need charge about 5 hours as the charging current size.Because the difference of battery capacity, so the scope of application of charger is also different.But existing charger often has only two grades of charge modes: standard 10 multiplying power charge modes and quick 30 multiplying power charge modes, the suitable rechargeable battery capacity of these two kinds of chargers has five kinds of 500mAh, 650mAh, 700mAh, 1200mAh and 1400mAh at present.

Known in addition battery charging mode according to user has constant current charge, constant voltage charge, constant current constant voltage mixed mode, charge and discharge the charging modes put and the simplest " tradition charging " mode etc.Its characteristics separately are as follows:

1, constant current charge mode: it avoids the battery heating too high to utilize the mode of control charging current, but battery heating phenomenon is still relatively more serious.

2, constant voltage charging method: its cost is low, realize easily, but it is serious to be recharged the heating situation of battery.

3, constant current constant voltage mixed charged mode: its effect is between the two above-mentioned, and the heating situation too.

4, charge and discharge the charging modes of putting: make rechargeable battery heating, utilize the heating temp that reduces rechargeable battery at discharge regime, the heating temp of battery too high purpose not when reaching charging.

5, the simplest " tradition charging " mode: after the mode with rectification of only being meant converts alternating current to Rectified alternating current, directly charge, voltage swing, current strength all change with the interior change that is recharged battery, its cost is minimum, control circuit is simple, but maximum shortcoming: battery heating situation is the most serious, thereby also maximum to the damage that is recharged battery.

According to the concern of the inventor to above-mentioned various chargers and charging modes, existing various charger and charging method, the phenomenon that makes the battery heating when being charged, battery is all arranged, the utmost point can make the electrolyte liquefaction in the chewing gum battery that is recharged like this, because the effective charging of battery under different temperatures also can be had any different; If particularly chewing gum battery temperature is too high, the explosion or the damage of battery can take place when serious, also can shorten battery useful life generally speaking.

Therefore, can effectively overcome the rechargeable battery heating for the user provides a kind of, can be a kind of expectation of producer and user finish charging purpose New-type charge device more satisfactoryly again.

Summary of the invention

Purpose of the present invention: aim to provide a kind of brand-new charging device and charging method, wish that it not only reaches desirable charging effect, and in the process of charging, can avoid being recharged harm phenomenons such as the heating in pond and even explosion.

This quick charge device is made up of charger box 1, battery carrier 2, rectifier charging circuit plate 3 etc., it is characterized in that: described battery carrier 2 is provided with the cpu heat 6 and the copper 7 batteries cooling grooves 4 of forming of rising as high as the banks that mate with the chewing gum battery.

Described copper rising as high as the banks 7 is to be combined through hinge by two copper lids, and the surface of its groove lid is consistent with the shell of chewing gum battery and identical.

Described semiconductor cooler 5, the electronic transformer that its working power adopts cold light source to use, input voltage 220VAC, output voltage 12VAC be through the Schottky diode rectification, after the electrochemical capacitor filtering directly for the semiconductor cooler electric current of working.

Described semiconductor cooler 5 is close to copper 7 the outside of rising as high as the banks, and described cpu heat 6 is frame face thereon then.

This quick charge device according to above technical scheme proposition, owing to set up a low temperature, heat sink in the outside that is recharged battery, therefore so in the process of battery charge, can control the heating temp of chewing gum battery effectively, can prevent effectively very that rechargeable battery from answering the high temperature heating and generation that the electrolyte liquefaction that causes and battery explosion endanger phenomenon.

Description of drawings

Accompanying drawing 1 is a structural representation of the present invention;

Accompanying drawing 2 is the semiconductor cooler fundamental diagram.

Among the figure 1, charger box 2, battery carrier 3, rectifier charging circuit plate combination 4, battery cooling groove 5, semiconductor cooler 6, cpu heat 7, copper rising as high as the banks.

Embodiment

This quick charge device as shown in the figure is actually a kind of inventive improvements to existing congenerous chewing gum charger, this improvement be mainly reflected in following some:

1. on described battery carrier 2, be provided with one and rise as high as the banks 7, allow it become the heat radiation media with the copper of chewing gum battery coupling;

2. at the copper additional cooling device of forming by semiconductor cooler 5 and cpu heat 6 outside 7 of rising as high as the banks.

Making test and the detection done in this quick charge device through the inventor shows: adopting " tradition charging " mode (i.e. the most serious charging modes of heating), when using technical scheme of the present invention, under the large current charge state, its used time of charging can reduce to original sixth, as seen adopting under the low-temperature condition the chewing gum battery charge, is a kind of scientific and reasonable trial.Also can estimate simultaneously this kind mode is used for effect that alternate manners such as constant current charge, constant voltage charge, constant current constant voltage mixing charge to rechargeable battery can be better.
