Abstract
The utility model discloses an electric vehicle automatic power-off charging device, comprising a charger YC, wherein the charger YC comprises 220V AC power supply input ends 1 and 2, 12V fan power supply interfaces 3 and 4, and output ends 5 and 6, the AC power supply input ends 1 and 2, a starting switch K and an AC power supply input interface P1 form a charger YC input loop, the output ends 5 and 6 and a charger output interface P2 form a charger YC output loop, the 12V fan power supply interfaces 3 and 4 are connected with a relay J, the relay J comprises two normally open contacts, one normally open contact is connected to the charger YC input loop, the other normally open contact is connected to the charger YC output loop. The electric vehicle automatic power-off charging device of the utility model, on one hand, protects safety of a storage battery to prolong a service life of the storage battery, on the other hand, disconnects an input power supply to save electric energy.
Description
Technical field
The utility model relates to a kind of auto-breaking charging device, is specially a kind of electric motor car auto-breaking charging device.
Background technology
The charging of electric bike battery is charged with charger.Charger in the market does not all have automatic circuit break function, is full of after electricity at storage battery, and charger can not auto-breaking, still has one part of current to be filled with storage battery, and this one part of current is very large to the harm of storage battery.For a long time, will make the too early dehydration of storage battery, reduce the useful life of storage battery.
Summary of the invention
The utility model has solved the deficiencies in the prior art, and a kind of making electric motor car auto-breaking charging device is simply and easily provided.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of electric motor car auto-breaking charging device, comprise charger YC, described charger YC comprises 220V ac power input end 1, 2, 12V fan power supply interface 3, 4, output 5, 6, described ac power input end 1, 2, starting switch K, AC power input interface P1 composition charger YC input circuit, described output 5, 6 form charger YC output loop with charger output interface P2, at described 12V fan power supply interface 3, on 4, connect relay J, described relay J comprises two normally opened contacts, a normally opened contact is connected on described charger YC input circuit, another normally opened contact is connected on described charger YC output loop.
Further, the normally opened contact one end on described charger YC input circuit is connected to starting switch K one end, and the other end is connected between the other end and ac power input end 2 of starting switch K; Chang Kaikai contact on described charger YC output loop is connected between output 5 and output interface P2.
The utility model utilizes the 12V power supply of charger fan to drive a 12V relay, and relay is two loops of control inputs output respectively.Be full of after electricity on storage battery, the 12V power supply of charger fan disappears, and relay has just disconnected two loops of input and output.So just realize storage battery and be full of the electricity object of auto-breaking afterwards, protected on the one hand the safety of storage battery, extended the useful life of storage battery, disconnected on the other hand input power and saved electric energy.
Brief description of the drawings
Fig. 1 the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of electric motor car auto-breaking charging device, comprise charger YC, described charger YC comprises 220V ac power input end 1, 2, 12V fan power supply interface 3, 4, output 5, 6, described ac power input end 1, 2, starting switch K, AC power input interface P1 composition charger YC input circuit, described output 5, 6 form charger YC output loop with charger output interface P2, at described 12V fan power supply interface 3, on 4, connect relay J, described relay J comprises two normally opened contacts, a normally opened contact is connected on described charger YC input circuit, another normally opened contact is connected on described charger YC output loop.
Further, the normally opened contact one end on described charger YC input circuit is connected to starting switch K one end, and the other end is connected between the other end and ac power input end 2 of starting switch K; Chang Kaikai contact on described charger YC output loop is connected between output 5 and output interface P2.
As shown in Figure 1, the utility model operation principle is as follows:
When the utility model charging, press starting switch K, 220V AC power is input to the ac power input end 1 of charger YC by K switch, 2, charger is started working, fan entry into service, the fan power supply interface 3 of charger, the 12V power drives relay J adhesive of 4 outputs, two contact conductings, at this moment decontrol after starting switch K, 220V AC power continues to be input to the ac power input end 1 of charger YC by a contact of relay, 2, charger YC output 5, 6 by another contact of relay, charge to electromobile battery through output interface P2 again.
When electromobile battery is full of after electricity, charger fan shuts down, the 12V power supply of fan power supply interface 3,4 outputs of charger YC disappears, relay J disconnects, because two contacts of relay J are serially connected in respectively in the input and output loop of charger, disconnect the input and output loop of charger.Charger quits work completely, and the electricity of storage battery also can reverse flow not got back in charger, can not lose electric energy.
