Description
Technical field
The utility model relates to a kind of battery of electric vehicle tutoring systems.
Background technique
With the development of electric vehicle, the coordination problem of energy and environment has very big improvement, before the development of electric vehicle
Scape is very wide.But the development of electric vehicle receives the restriction of different factors, wherein crucial problem show the energy (
It is exactly battery) two aspects of itself and energy management.Energy problem, that is, battery itself performance capability problems, such as
Battery life, safety coefficient, consistency etc.；Energy management problem, that is, power battery problem of management, perfect battery management
System can not only allow user in time, understand battery status in detail, and can guarantee cell safety run.So, why
Sample preferably makes battery service user under conditions of existing battery performance, improve and optimization battery management system just at
Extremely urgent mission.
And the study of lithium battery management system is also fused in teaching, i.e. lithium battery management system simulated experiment.It is existing
Some lithium battery management system simulated experiments, directly will be electric using Circuit assembly battery pack as shown in Figure 1 during real training
After 11 parallel connection of pond, it is connect, is easy to appear in operation short with electric vehicle positive and negative electrode using positive lead 12, negative lead 13
Phenomena such as road, reversed positive and negative anodes and cause danger, or even cause battery explosion.
Utility model content
The technical problem to be solved by the utility model is to provide the battery of electric vehicle teaching systems that one kind can protect circuit
System.
The technical scheme adopted by the utility model is battery of electric vehicle tutoring system, including at least two electricity in parallel
Pond, the positive and negative electrode of battery couple positive lead, negative lead respectively, and positive lead, negative lead are separately connected electricity
Anode, the cathode of motor-car are in series with the first fuse on the positive lead of each battery, are parallel between positive lead
Battery parallel connection is formed single-stage battery pack by the setting of the second fuse, the first fuse, the second fuse, has both met electric vehicle electricity
The functional requirement of pond management system battery, and can prevent batteries in parallel connection from short cut with each other, is big caused by parallel circuit external short circuit
The failures such as electric current.
Further, the current rating of the first fuse is ten times of the second fuse, enables the first fuse
Prevent having high current ability to work while external positive and negative anodes short circuit, the second fuse can prevent battery in single-stage battery pack
It is short-circuit when internal parallel when battery pole back connection.
Further, be in series with diode between the first fuse and the interface of positive lead, diode it is specified
Current value is twice of the first fuse, prevents single-stage battery pack anti-inserted and occurs on high pressure Opposite side loading to single-stage battery pack,
With inverse inserting-preventing defencive function.
Further, the interface of positive lead, the respectively red isolation interface of interface of negative lead, black insulation
Interface prevents outside batteries positive and negative electrode reversed convenient for identification.
Further, battery outer surface is provided with insulating layer, prevents battery metal surface from short circuit occur, can be safer
Assembled battery group.
Further, the spacing difference energy between the spacing between the interface of positive lead and the interface of negative lead
It is reversed enough to more efficiently prevent from polarity.
The beneficial effects of the utility model are:
(1) the utility model can effectively prevent to get an electric shock in lithium battery management system simulated experiment process mesohigh, thus
Improve the safety of test.
(2) the utility model can effectively prevent battery short circuit during lithium battery management system simulated experiment, to mention
The high safety of test.
(3) battery polar is anti-inserted during the utility model can effectively prevent lithium battery management system simulated experiment, from
And improve the safety of test.
Detailed description of the invention
Fig. 1 is lithium battery management system simulated experiment battery connection circuitry figure in the prior art.
Fig. 2 is the utility model lithium battery management system simulated experiment battery connection circuitry figure.
In the figure, it is marked as 1- battery, 2- positive lead, 3- negative lead, the first fuse of 4-, 5- second insure
Silk, 6- diode, 11- battery, 12- positive lead, 13- negative lead.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Embodiment:
It is by taking the parallel circuit of two lithium batteries 1 as an example, two batteries 1 are in parallel as shown in Figure 2, on two batteries 1
Series connection one the first fuse, 4, diodes 6 connect second fuse 5 between the parallel circuit of two batteries 1, the
The load current value of one fuse 4 is 10A, and the load current value of the second fuse 5 is 1A, is inserted for 1 group of single-stage battery in order to prevent
Occurs high pressure Opposite side loading instead on 1 group of single-stage battery, the rated current of diode 6 is 20A.It is protected with inverse inserting-preventing, is
It prevents 1 metal surface of battery from short circuit occur, 1 outer surface of battery is provided with the insulating layer on cladding battery 1 surface, insulating layer
Material can choose polytetrafluoroethylene (PTFE).When actual fabrication, the first fuse 4, the second fuse 5, diode 6 are pressed into Fig. 2 first
Shown position is welded on the pedestal of battery 1, then with positive lead 2, negative lead 3 by diode 6, the first fuse
4, the second fuse 5 connects, and two anode interfaces, two cathode interfaces are had on 1 pedestal of battery, even by anode
Wiring 2, negative lead 3 are connected on positive and negative anodes interface, for the ease of identification, prevent polarity is reversed, positive and negative electrode interface point
Not Cai Yong red isolation interface, black isolation interface, and the spacing between two red isolation interfaces is less than two black isolation interfaces
Between spacing, finally the positive and negative anodes of positive and negative electrode interface and electric vehicle are connect with connecting line by battery placing battery pedestal again
Mouth is connected, and can be tested.Due to being connected using multistage lithium battery battery pack, voltage is lower than 80V, to ensure student oneself group
Safety when dress.
