Description
Technical field
The present invention relates to battery charger, more specifically be meant a kind of charger, this charger can be tested when charging voltage, current value in good time.
Background technology
Many known, battery uses more and more universal as a kind of storing mode of the energy.But the manufacturing materials of battery such as nickel, very big to the influence of environment every materials such as, mercury, a button cell can pollute 600,000 premium on currency, but has produced the chargeable battery that repeated multiple times is used thus.The generation of chargeable battery is promoted the effect of adding fuel to the flames of having played for mobile product, and as the frequent electric motor car that uses of people, computer, mobile phone, electric tool etc., matching used with chargeable battery is exactly charger.
Charging process is preferably under the state of constant voltage, constant current carries out, otherwise will influence the performance of rechargeable battery, the most common as charging shorten service time once, life-span of battery reduces, particularly outstanding be that the show label of charger shows that battery finished charging but can not use or the like normally, inconvenience has been with in daily use.The charge condition of charger mainly relies on all kinds of indicator lights to show at present, voltage in the time of can not reacting charging very accurately, the actual conditions of electric current.
The utility model content
The technical problem that the utility model solves provides a kind of charger, can show charging current and charging voltage in the charging process of charger in real time.
For solving above-mentioned technical problem, the utility model is achieved by the following technical programs:
A kind of charger, the rectification unit that comprises charger, the power input of rectification unit receives the power output end output DC of alternating current, rectification unit, also comprise indicating member, the power input of described indicating member is connected with the power output end of rectification unit, and described indicating member comprises voltage indicating section and electric current indicating section.
Described voltage indicating section comprises voltmeter, voltmeter reversing switch.
Described electric current indicating section comprises ammeter, ammeter reversing switch.
Described voltage indicating range 0～100V, electric current indicating range 0～20A.
The interface that the power supply input of described indicating member, output dispose several specifications.
Adopt charger of the present utility model, by the real-time charging voltage value of voltage indicating section acquisition wherein, by the real-time charging current value of electric current indicating section acquisition wherein.This apparatus structure is simple, and is easy to operate, and the scope of application is wide.
Description of drawings
Fig. 1 is the operation principle schematic block diagram of a kind of charger of the utility model;
Fig. 2 is the electric principle schematic of the indicating member among Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of charger as shown in Figure 1 and Figure 2, the rectification unit that comprises charger, the power input of rectification unit receives the power output end output DC of alternating current, rectification unit, also comprise indicating member, the power input of described indicating member is connected with the power output end of rectification unit, and described indicating member comprises voltage indicating section and electric current indicating section.The voltage indicating section comprises voltmeter 4, voltmeter reversing switch 2, and the electric current indicating section comprises ammeter 5, ammeter reversing switch 3.Wherein the voltage indicating range is 0～100V, and the electric current indicating range is 0～20A.The interface that the power supply input of indicating member, output dispose several specifications respectively.
During use, the power output end of charger rectification unit is connected with the power input of indicating member, be connected in parallel on the voltage readings that the voltmeter 4 on the power line 1 shows under the current charger Light Condition this moment, if, then stir voltmeter reversing switch 2 and adjust voltmeter 4 polarity for negative.Disconnect the charger power supply, the input of rechargeable battery is connected on the power line 1, this moment, voltmeter 4 showed the current voltage readings of rechargeable batteries, if for negative, illustrate that rechargeable battery polarity is opposite with charger polarity, adjusted the polarity of rechargeable battery then.Connect the power supply of charger once more, watch the ammeter 5 of connecting with power line, if ammeter 5 readings are negative then stir ammeter reversing switch 3 and adjust the ammeter direction, make ammeter 5 show the normal current reading, the numerical value of voltage, electric current when this moment, voltmeter 4 and ammeter 5 respectively online demonstrations were charged.
Bring in the output that substitutes rectification unit, the numerical value of voltage, electric current under the then online demonstration rechargeable battery discharge condition with the input of discharge equipment.
At the input of indicating member, the interface that output disposes several specifications respectively, can play the effect of interface conversion to carrying out charge and discharge between the unmatched equipment of port.
