Summary of the invention
The utility model provides a kind of above-mentioned all dissimilar civilian use electric cars all to be suitable for charger, claims civilian use electric car global function charger, because it is the product that caters to the market demand development, thereby market potential must be arranged, and corresponding also must have larger economic benefit.
For reaching above-mentioned purpose, the technical problem that needs solution or overcome is: make a transformer, its primary voltage is that alternating current 220V, rated power are 120W, secondary voltage is respectively and exchanges 12V, exchanges 24V, exchanges 36V, exchanges 48V and exchanges 60V, this transformer is made, and is that the utility model core technology is crucial.
In sum, the technical solution of the utility model is: input and output circuit are arranged, and during charging, input circuit is by current-limiting resistance R
1With indicator light X
1In parallelly be composed in series with safety box R, K switch and alternating current 220V power supply with power transformer is elementary after series connection, output circuit is by current-limiting resistance R again
2, indicator light X
2Connect with the shunt circuit that battery E and filter capacitor C form again with power rectifier diode D parallel connection after series connection, then be composed in series with the lead-out terminal that exchanges 12V, interchange 24V, interchange 36V, interchange 48V and interchange 60V.
Description of drawings
Fig. 1 is the utility model way circuit figure.In figure, the E representative is recharged the civilian use electric car battery of above-mentioned three types.
Embodiment
According to the above, make a transformer, be that core technology of the present utility model is crucial.Be produced as follows: my patent No. is the power transformer (calling former transformer in the following text) of 200920268824.1 Full automatic universal emergency lights, and performance is very stable, and we as foundation, make new transformer with it.Known former primary power, voltage, coil turn, wire diameter are respectively 5W, alternating current 220V, 2181 circles, 0.12mm, and new transformer requires elementary power 120W, alternating current 220V, 2181 circles of being followed successively by, and wire diameter is made as D
2, according to electrotechnics, can utilize following formula to try to achieve:
Central P

1Be followed successively by 5W, 12V, 120 circles, 0.46mm, new transformer secondary output requires to be followed successively by power 120W, 60V electrical safety voltage, 600 circles, wire diameter and is made as D
2', utilize above-mentioned same equation to try to achieve D
2' ≈ 1.0mm.Like this, newly transformer just can have been worked it out.Because new transformer secondary output is comprised of 5 identical coils, obvious secondary 120W power and interchange 60V voltage are uniformly distributed on 5 coils, each coil has 24W power and exchanges 12V voltage, like this on the summit of 1,2,3,4 and 5 coil namely 1,2,3,4 and be followed successively by 24W and 12V, 48W and 24V, 72W and 36V, 96W and 48V, 120W and 60V with obtaining respectively power and direct voltage during 5 chargings after rectification.
According to power, voltage, current formula P=IU as can be known above-mentioned various charge condition charging rated current be 2A, meet battery charge or discharge electric current and mustn't surpass the 2.16A requirement, reach thus us and want the target that reaches.
Below in conjunction with Fig. 1, from embodiment, the utility model is discussed further.Input circuit and output circuit are arranged, and during charging, input circuit is by current-limiting resistance R
1With indicator light X
1The series connection after with power transformer elementary in parallel again with safety box R, K switch
1, the alternating current 220V power supply is composed in series; Output circuit is by current-limiting resistance R
2, indicator light X
2Connect with the shunt circuit that battery E and filter capacitor C form again with power rectifier diode D parallel connection after series connection, then be composed in series with the lead-out terminal that exchanges 12V, interchange 24V, interchange 36V, interchange 48V and interchange 60V.
Closed K, alternating current process safety box R one tunnel is through R
1Make X
1Luminous, expression has alternating current to exist, another road through power transformer elementary make secondary 1,2,3,4 and 5 each produce the voltages that exchange 12V, exchange 24V, exchange 36V, exchange 48V and exchange 60V, during charging, if central certain a bit to the E charging, alternating current one tunnel is through resistance R
2And indicator light X
2, X
2Luminous, table charges, when 1,2,3,4 and 5 certain some interchanges of output after rectification with battery E no-voltage, this moment, charging stopped, indicator light X
2Extinguish.Because battery discharge can not discharge, thereby a point voltage is always arranged when beginning to charge, offset power transformer secondary generation DC charging voltage and make charging current forever less than rated current 2A.In addition, because the alternating current voltage identical with the battery rated voltage charges to E, so overcharge never, make battery life elongated.The utility model can be done dissimilar and the automobile-used family charging of different brands civilian use electric is used, and also can fix or the use of awaiting orders of mobile civilian use electric car maintenance station.
