Abstract
The invention discloses a small electric car distributed power and electrical system. The small electric car distributed power and electrical system comprises an emergency stop switch, a plurality of motor controllers, a DC/DC convertor, a direct current contactor, a plurality of hub motors and a battery, wherein the emergency stop switch is arranged to control battery power output; the multiple hub motors are suspended on rear driving car wheels of an electric car independently; each hub motor is controlled by the corresponding motor controller; the DC/DC convertor converts battery end voltage into low voltage; and the direct current contactor supplies the low voltage to the motor controllers. Through the small electric car distributed power and electrical system, the safety and stability of the small electric car are improved.
Description
Technical field
The present invention relates to a kind of small-sized electric vehicle distributed-power and electrical system.
Background technology
As low-carbon economy becomes the theme of China's economic development, electric automobile is used as new forms of energy strategy and intelligent grid
Important component part, and one of emerging strategic industries that State Council determines, will become Chinese Automobile Industry ' from now on and
The emphasis of energy industry development.Shandong Province's small-sized electric vehicle production and marketing in 2015 reaches 37.15 ten thousand, grows beyond within continuous 3 years
50% national production and marketing breaks through 500,000.Small-sized electric vehicle possesses the low advantage with energy efficient of price, meets town and country vast
The needs of masses' trip, it is contemplated that Shandong Province's small-sized electric vehicle production and marketing in 2016 will increase by more than 50%.
The expansion of market scale proposes new challenge to the small-sized electric vehicle industry in the whole nation.At present, it is small-sized on market
Electric automobile quality is uneven, and security performance is low.
The content of the invention
The present invention is in order to solve the above problems, it is proposed that a kind of small-sized electric vehicle distributed-power and electrical system, this
Invention is driven to small-sized electric vehicle using multiple motors and electric machine controller, improve small-sized electric vehicle safety and
Stability.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of small-sized electric vehicle distributed-power and electrical system, including emergency stop switch, multiple electric machine controllers, DC/
DC transducers, D.C. contactor, multiple wheel hub motors and battery, wherein, the emergency stop switch is configured to control battery power
Output, the plurality of wheel hub motor, in electric automobile driving moment, each wheel hub motor is by a motor control for independent suspension
Device is controlled, and the battery terminal voltage is converted to low pressure by the DC/DC transducers, and low pressure is supplied institute by the D.C. contactor
State electric machine controller.
The electric machine controller and wheel hub motor are arranged on wheel hub, all-wheel drive.
The DC/DC transducers are arranged on vehicle body front side or rear side.
The D.C. contactor is arranged on battery case both sides.
Distributed-power and electrical system, safety and stability, when one or several electrical faults, other non-faulty motors can
Continue to drive to repair location and overhauled.
Small-sized electric vehicle, refers to low-speed small electric automobile on market, the compact simplicity of this electric automobile, travel speed
It is not high, it is easy to ride instead of walk in city.Multiple motors are installed on wheel hub, improve vehicle body stability and safety.Small-sized electric vehicle point
Cloth dynamical system instead of the change speed gear box of orthodox car, directly drive hub rotation.
Beneficial effects of the present invention are：
(1) improve the safety and stability of small-sized electric vehicle.
(2) In-wheel motor driving, complete vehicle structure are simple.
Description of the drawings
Fig. 1 is the population structure schematic diagram of the present invention.
System structure schematic diagrams of the Fig. 2 for the present embodiment.
Specific embodiment：
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
A kind of small-sized electric vehicle distributed-power and electrical system, including 2 or 4 wheel hub motors, set of cells, with electricity
The equal electric machine controller of machine quantity, DC/DC transducers, emergency stop switch, D.C. contactor；
The emergency stop switch, in emergency circumstances cutting off battery power output；
The plurality of electric machine controller, for controlling correspondence wheel hub motor；
The DC/DC transducers, for being converted to the low pressure used by electrical equipment on car by battery terminal voltage；
The D.C. contactor, powers for controlled motor controller.
The plurality of wheel hub motor, in small-sized electric vehicle driving moment, wheel hub motor independent suspension；
The battery, provides power supply for small-sized electric vehicle and drives power.
Although the above-mentioned accompanying drawing that combines is described to the specific embodiment of the present invention, not to present invention protection model
The restriction enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
The various modifications made by needing to pay creative work or deformation are still within protection scope of the present invention.
