Abstract
The invention discloses a kind of Novel motor controller low-tension supply electricity getting device, innovative point is：Including electric machine controller, permanent magnet synchronous motor, the small storage battery of low pressure and fairing；The advantage of the invention is that：Small storage battery takes the mode of electricity only to pass through Vehicular charger and takes electricity from high voltage power battery pack in pure electric automobile.Pure electric automobile is in high-speed cruising, motor speed is very high at this time, so the counter electromotive force of motor also can be very big, according to electric machine controller strategy, electric current must additionally be increased to weaken counter electromotive force just not will lead to motor out of control, i.e. so-called high speed weak magnetic control, the electric current additionally increased in this way is not only no in all senses to the dynamic property promotion of electric system, and also results in electric system temperature rise increase.It if counter electromotive force is exported by fairing to small storage battery, can charge to small storage battery, and can also be beneficial to weakening electric system temperature rise, increasing vehicle course continuation mileage.
Description
Technical field
The present invention relates to a kind of power supply electricity getting device, especially a kind of Novel motor controller low-tension supply electricity getting device.
Background technique
Currently, the small storage battery in conventional fuel oil car is that the small generator carried on vehicle in operation usually charges.
But in new-energy automobile, especially on pure electric automobile, due to the following aspects：a）Small storage battery use is too long；
B) when electrical equipment opens more on vehicle；Small storage battery feed is frequently resulted in, it could even be possible to it is low to will cause electric system report
Pressure under-voltage fault causes vehicle to cast anchor.
Summary of the invention
Novel motor controller low-tension supply electricity getting device simple, at low cost is connected it is an object of the invention to provide a kind of,
It solves one or more of the above-mentioned prior art problem.
In order to solve the above technical problems, the technical scheme is that：A kind of Novel motor controller low-tension supply takes electricity
Device, innovative point are：Including electric machine controller, permanent magnet synchronous motor, the small storage battery of low pressure and fairing；Motor control
Device is connected with magneto, and low pressure small machine is connected with electric machine controller, the series circuit of electric machine controller and magneto with
The series circuit of low pressure small machine and electric machine controller is mutually indepedent, the input terminal access electric machine controller and permanent magnetism of fairing
The series circuit of motor, the series circuit of output end access the low pressure small machine and electric machine controller of fairing.
In some embodiments, fairing is rectifier.
The advantage of the invention is that：Small storage battery takes the mode of electricity only to pass through Vehicular charger in pure electric automobile
（DCDC）Electricity is taken from high voltage power battery pack.For pure electric automobile in high-speed cruising, motor speed is very high at this time, so motor
Counter electromotive force also can be very big, according to electric machine controller strategy, it is necessary to which the additional electric current weakening counter electromotive force that increases just not will lead to electricity
Machine is out of control, i.e., so-called high speed weak magnetic control, the electric current additionally increased in this way does not only have the dynamic property promotion of electric system
In all senses, and electric system temperature rise increase is also resulted in.If counter electromotive force is passed through fairing（ACDC）It exports to small
Storage battery can charge to small storage battery, and can also be beneficial to weakening electric system temperature rise, increasing vehicle course continuation mileage.
Detailed description of the invention
Fig. 1 is a kind of line map of Novel motor controller low-tension supply electricity getting device of the present invention.
Specific embodiment
With reference to the accompanying drawings of the specification, the present invention is described in more detail.
A kind of Novel motor controller low-tension supply electricity getting device as shown in Figure 1, including electric machine controller 1, permanent magnetism are same
Walk motor 2, the small storage battery 3 of low pressure and fairing 4；Electric machine controller 1 is connected with magneto, low pressure small machine and motor control
Device 1 processed is connected, the series circuit of the series circuit and low pressure small machine and electric machine controller 1 of electric machine controller 1 and magneto
Independently of each other, the series circuit of input terminal the access electric machine controller 1 and magneto of fairing 4, the output of fairing 4
Terminate the series circuit into low pressure small machine and electric machine controller 1.
In some embodiments, fairing 4 is rectifier.
The advantage of the invention is that：Small storage battery takes the mode of electricity only to pass through Vehicular charger in pure electric automobile
（DCDC）Electricity is taken from high voltage power battery pack.For pure electric automobile in high-speed cruising, motor speed is very high at this time, so motor
Counter electromotive force also can be very big, according to 1 strategy of electric machine controller, it is necessary to which the additional electric current weakening counter electromotive force that increases just not will lead to electricity
Machine is out of control, i.e., so-called high speed weak magnetic control, the electric current additionally increased in this way does not only have the dynamic property promotion of electric system
In all senses, and electric system temperature rise increase is also resulted in.If counter electromotive force is passed through fairing 4（ACDC）It exports to small
Storage battery can charge to small storage battery, and can also be beneficial to weakening electric system temperature rise, increasing vehicle course continuation mileage.
The scope of the present invention is defined by the appended claims and its equivalents.The above is only the present invention
Preferred embodiment, it is noted that those skilled in the art, do not depart from the invention design premise
Under, some similar deformation and improvement can be made, within these also should be regarded as protection scope of the present invention.
