Description
Technical field
The utility model relates to a kind of charging battery of electric vehicle device, especially a kind of not only can be at a slow speed but also the charging battery of electric vehicle device of quickly-chargeable.
Background technology
At present; The charging battery of electric vehicle device that generally uses in the society has varied; Single switch power supply formula charger commonly wherein, its operation principle is constant current, high constant voltage, low constant voltage syllogic charging basically, has power saving, advantage that cost is low; But the electric time that this charger fills is long, and service efficiency is low.Use the syllogic quick charger charging of big electric current; Electric current is big during charging, and it is high that cell voltage is floated, because quick charger has only a control chip constant current constant voltage; In case voltage floats high, reach charger soon and set the low constant-voltage phase of high constant voltage conversion.Because it is big more that the big more voltage of charging current floats, so the low constant-voltage phase of entering is fast more.The pressure value height that the charger that has is set the low constant-voltage phase of high constant voltage conversion will make battery heating, distortion, dehydration easily; Get into low constant-voltage phase; The low battery charge foot that helps of constant voltage value, battery is not easy the heating distortion, and constant voltage value height also can make the battery heating; Cause battery to be prone to dehydration, influence battery life.So, using big electric current syllogic quick charger charging, the big electric current of leading portion can be realized quick charge, but because voltage floats greatly, causes too fast entering to hang down constant-voltage phase, and the low constant voltage of back segment also needs the long period just can be full of.Therefore the charging interval is also longer.The high forced charge of charger constant voltage value that has, the unfavorable condition that makes battery heating, distortion, dehydration occur and overcharge easily.
Summary of the invention
The purpose of the utility model provides a kind ofly both can charge at a slow speed, quickly-chargeable again, but do not overcharge, owe to fill, be not easy to generate heat, dehydration, do not influence battery life, parallel charging battery of electric vehicle device that service efficiency is high.
For achieving the above object, the technical scheme of the utility model is:
A kind of parallel charging battery of electric vehicle device comprises the switch power supply type charger, it is characterized in that:
Described switch power supply type charger is several, is connected in parallel with input, the output of lead with several switch power supply type chargers, and input is connected with attaching plug, and output is connected with accessory power outlet.
On the power line between the power input of said switch power supply type charger, be provided with control switch, the charger that several are parallelly connected is divided into one section plurality of sections charger.
Described control switch is a driving switch, the charger of each section of gear control or plurality of sections.
The parallel charging battery of electric vehicle device of above structure can be realized fast or charging at a slow speed through regulation control switch or driving switch.The charger that drops into charging is few more, and the time of the shelves that charge the battery is long more, i.e. charging is slow, and corresponding gear is the trickle charge gear; Otherwise, being quick charge, corresponding gear is for fill gear soon.When this driving switch is adjusted to slow shelves and charges, have only the work of part switch power supply type charger, the charging interval is longer, and battery had been full of electricity when the rechargeable lamp of treating this part work charger became full green light by full red light.When driving switch was adjusted to fast shelves and charges, whole or most switch power supply type charger was devoted oneself to work, and gets into the big electric current quick charge phase I to high constant voltage second stage; Because large current charge voltage floats high; Reaching when high constant voltage is changeed low constant voltage value has the partial charging device just to get into low constant-voltage phase, so charging current also weakens thereupon, the battery floating voltage that has effectively reduced; Can keep a part of charger and be in high constant-voltage phase quick charge; Some charger gets into low constant-voltage phase again when arriving high constant voltage once more and change low constant voltage value, and the battery floating voltage descends again, and some charger is also in high constant-voltage phase quick charge.Be reciprocated to last according to this, all charger charging red lights become green light battery when all rechargeable lamps become green light one by one and have been full of electricity.Because charger does not add height constant voltage value and high constant voltage value, so battery is not easy heating, dehydration, overcharges and owes to fill, do not influence battery life.This parallel electric car charger charging is fast, efficient is high, is applicable to the charging of various battery of electric vehicle.
Description of drawings
Fig. 1 is the structural representation of the parallel charging battery of electric vehicle device of the utility model.
Fig. 2 is the structural representation that on the basis of Fig. 1, constitutes the multistage charger.
In the drawings, switch power supply type charger 1, control switch 2, lead 3, power input plug 4, charging accessory power outlet 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Shown in Figure 1; The structural representation of the parallel charging battery of electric vehicle device of the utility model can be known from figure, is connected in parallel with input, the output of lead 3 with a plurality of switch power supply type chargers 1; Input is connected with power input plug 4, and output is connected with accessory power outlet 5.Described switch power supply type charger 1 is a prior art products, and is on sale on the market.Between first and second charger 1 and power line, be provided with control switch 2, promptly when control switch 2 disconnected wanting, have only first charger 1 work, the charging current of output is little, and charging is slow; When connecting control switch 2, all charger 1 is all worked, the big charging of the charging current of output, and charging is fast.
Described switch power supply type charger 1 is a prior art products, and is on sale on the market.And, be not limited to syllogic Switching Power Supply charger.
Shown in Figure 2, be the structural representation that on the basis of Fig. 1, constitutes the multistage charger, from figure, can see; On two adjacent charger power cords in the middle of a plurality of parallel chargers 1; Be provided with control switch 2a again, the control switch 2 in Fig. 1 is divided into three sections with a plurality of parallel chargers 1.Certainly, all right this method is used control switch, and a plurality of parallel chargers 1 are divided into plurality of sections, and the switch of connection is many more, and the charger of input is many more, and it is fast more to charge; Otherwise it is slow more to charge.
Principle according to segmentation control; Control switch can adopt driving switch on sale on the market; Through one of several gears control, several or whole charger 1 work, with realize filling at a slow speed, middling speed is filled and the charging rate of each grade such as quick charge, adapts to the requirement of different battery charge.
