Description
Technical field：
Electric automobile energy saving technical field is the utility model is related to, more particularly to a kind of brake energy recovering system.
Background technology：
On electric automobile, when motor does not operate battery, the inertia of automobile make wheel drive motor (now into
For generator) rotate and generate electricity as power battery charging, and caused electric current easily reaches during electric vehicle brake
Higher value, in the range of about hundreds of peaces, this is more much bigger than the absorbent charging current of electrokinetic cell institute.If electrokinetic cell
In the case of undercharge, caused electric energy will make electrokinetic cell inadequately charge during electric braking, can so damage dynamic
Power battery simultaneously greatly reduces its life expectancy；In addition, when electrokinetic cell is close to its maximum charge amount, produced by during electric braking
Electric energy electrokinetic cell will be made to overcharge.So if this charging process is not controlled by, will necessarily have a strong impact on dynamic
The performance of power battery, or even directly damage electrokinetic cell.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form
Technology.
Utility model content：
The purpose of this utility model is to provide a kind of brake energy recovering system, above-mentioned of the prior art so as to overcome
Defect.
To achieve the above object, the utility model provides a kind of brake energy recovering system, including：BMS components, generate electricity
Machine, brake monitor, motor；The BMS components include electrokinetic cell, super capacitor, the electrokinetic cell, super capacitor difference
By circuit and motor connection, powered for motor；The generator is connected by circuit with super capacitor, the brake monitor
Including electric brake, mechanical brake, the electric brake is connected by circuit with generator；When electric brake starts, hair
Motor work is charged for super capacitor.
Compared with prior art, the utility model has the advantages that：
The addition of super capacitor during effectively improving electric vehicle brake caused high current it is uncomfortable to electrokinetic cell
The problem of locality is charged or overcharged, while also solve the problems, such as electrokinetic cell heavy-current discharge during startup, so as to significantly
Extend the service life of electrokinetic cell.The recycling of energy is more the increase in the endurance of electric car.
Brief description of the drawings：
Fig. 1 is the utility model brake energy recovering system structural representation；
Reference is：1-BMS components, 2- generators, 3- brake monitors, 4- motors；The super electricity of 5- electrokinetic cells, 6-
Hold；7- electric brakes, 8- mechanical brakes.
Embodiment：
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in figure 1, a kind of brake energy recovering system, including：BMS components 1, generator 2, brake monitor 3, motor
4；The BMS components 1 include electrokinetic cell 5, super capacitor 6, and the electrokinetic cell 5, super capacitor 6 pass through circuit and electricity respectively
Machine 4 connects, and is powered for motor 4；The generator 2 is connected by circuit with super capacitor 6, and the brake monitor 3 includes electricity
Brake 7, mechanical brake 8, the electric brake 7 are connected by circuit with generator 2；When electric brake 7 starts, generate electricity
The work of machine 2 is charged for super capacitor 6.
During automobile normal running, the bio-occlusion motor 4 of electrokinetic cell 5 is powered, and drives vehicle forward, now generator 2
Idle running does not generate electricity；When needing to slow down or braking, electrokinetic cell 5 stops powering to motor 4, but because vehicle inertia drags
Dynamic motor 4 remains in operation, and now electric brake 7 starts in brake monitor 3, and generator 2 works, and starts to generate electricity, the work of generator 2
One and motor racing electromagnetic torque in opposite direction can be produced after work, kinematic system is acted on, vehicle is reduced speed now, simultaneously
The electricity of generator 2 can be stored in super capacitor 6.Caused high current is to power during effectively improving electric vehicle brake
The problem of battery 5 inadequately charges or overcharged.
During automobile starting, super capacitor 6 is that motor 4 is powered, and electrokinetic cell 5 is used as auxiliary power supply, is moved when solving startup
The problem of power 5 heavy-current discharge of battery, so as to substantially prolongs the service life of electrokinetic cell 5.
The foregoing description to specific illustrative embodiment of the present utility model is to illustrate and the purpose of illustration.These
Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explain certain principles of the present utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the present utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shape
Formula is limited.
