Abstract
The invention provides an electric car power system. The electric car power system comprises a power battery, a control system, a motor and a drive shaft, wherein the power battery and the motor are controlled by the control system. The electric car power system further comprises a metal air battery controlled by the control system. Both the power battery and the metal air battery can output power under the control of the control system. By the adoption of the electric car power system, the characteristics of short starting time of an ordinary power battery and high energy density of the metal air battery are combined, and therefore the defects that the power battery is low in energy density and therefore an electric car is short in driving range are remedied, and the defects that the metal air battery is low in power density and long in starting time can also be avoided.
Description
Technical field
The invention relates to the electric vehicle engineering field, and particularly about a kind of power system of electric automobile.
Background technology
It is power that electronlmobil refers to the vehicle power, travels with power wheel, meets the vehicle of arteries of communication, the every requirement of legislative control on safety.Because less to the relative orthodox car of environmental concerns, its prospect is extensively had an optimistic view of, but current techniques is still not exclusively ripe.
Power supply provides electric energy for the driving motor of electronlmobil, and electrical motor is converted into mechanical energy with the electric energy of power supply, by driving device or directly drive wheel and equipment.At present, most widely used power supply is lead-acid storage battery on the electronlmobil, but along with the development of electric vehicle engineering, lead-acid storage battery is because specific energy is lower, and charging rate is slower, and the life-span is shorter, is replaced by other storage battery gradually.The power supply that is developing mainly is lithium ion battery.
The energy density of metal-air battery has great advantage than lithium ion battery, can be good at solving the short shortcoming of existing electronlmobil continual mileage, lithium ion battery was obtained important breakthrough aspect energy density before, metal-air battery was a kind of comparatively ideal energy source of electronlmobil.But metal-air battery has significant deficiency in power density with above run up time, and the energy source as electronlmobil is difficult to meet the demands separately.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of power system of electric automobile, with common the electrokinetic cell short and high advantages of metal-air battery energy density run up time, it is low both can to have remedied the electrokinetic cell energy density, cause the short shortcoming of electronlmobil continual mileage, also can avoid the metal-air battery power density low, the shortcoming that run up time is long.
A kind of power system of electric automobile of the present invention, comprise electrokinetic cell, control system, motor, and axle drive shaft, described electrokinetic cell and motor are subjected to the control of described control system, described power system of electric automobile also comprises metal-air battery, described metal-air battery is subjected to the control of described control system, described electrokinetic cell and described metal-air battery all can be under the control of described control system horsepower output.
In one embodiment of the invention, aforesaid electrokinetic cell has charging inlet.
In one embodiment of the invention, aforesaid electrokinetic cell is lithium ion battery or Ni-MH battery.
In one embodiment of the invention, aforesaid metal-air battery is aluminium-air cell or zinc-air battery.
In one embodiment of the invention, aforesaid control system is the entire car controller of automobile.
In one embodiment of the invention, aforesaid axle drive shaft is propons or the back axle of automobile.
The invention has the beneficial effects as follows, adopt power system of electric automobile of the present invention, with common the electrokinetic cell short and high advantages of metal-air battery energy density run up time, it is low both can to have remedied the electrokinetic cell energy density, cause the short shortcoming of electronlmobil continual mileage, also can avoid the metal-air battery power density low, the shortcoming that run up time is long.Metal-air battery can directly provide parts as increasing the energy in journey stage, need not carry out the switching process of energy, the system effectiveness height; Because metal-air battery need not replenish fuel oil as the main energy output unit that increases the journey stage, really realized zero oil consumption.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification sheets, and for above and other objects of the present invention, feature and advantage can be become apparent, below especially exemplified by embodiment, and conjunction with figs., be described in detail as follows.
Description of drawings
Fig. 1 is the structural representation of the preferred embodiment of power system of electric automobile of the present invention.
The specific embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and the effect thereof of the power system of electric automobile that foundation the present invention is proposed are described in detail as follows:
Relevant aforementioned and other technology contents, characteristics and effect of the present invention can be known to present in the following detailed description that cooperates with reference to graphic preferred embodiment.By the explanation of the specific embodiment, when can being to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the present invention, yet appended graphic only provide with reference to the usefulness of explanation, the present invention is limited.
Please refer to shown in Figure 1ly, the power system of electric automobile of preferred embodiment of the present invention comprises electrokinetic cell 1, metal-air battery 2, control system 3, motor 4, and axle drive shaft 5.
Electrokinetic cell 1 has charging inlet 12, can be lithium ion battery or Ni-MH battery etc., as main power output block, guarantees the vehicle performance requirement.
Metal-air battery 2 can be aluminium-air cell or zinc-air battery etc., as increasing the Cheng Nengliang output block, and the car load operating needs when solving electrokinetic cell 1 electric weight deficiency.
Control system 3 can be the entire car controller of automobile.Electrokinetic cell 1, metal-air battery 2, and motor 4 all is controlled the control of system 3.
Axle drive shaft 5 can be the propons of automobile, also can be the back axle of automobile.
When the electronlmobil of the power system of electric automobile of using preferred embodiment of the present invention starts, by 1 power supply of control system 3 control electrokinetic cells, electronlmobil is started.After the startup, can adopt different control policies, both can be stopped power supply by control system 3 control electrokinetic cells 1, and by metal-air battery 2 power supplies, namely electrokinetic cell 1 is powered at starting state, and metal-air battery 2 be in normal motoring condition power supply; Also can continue power supply by control system 3 control electrokinetic cells 1, when the electric weight of electrokinetic cell 1 is not enough (but should note still need keeping start vehicle once more than needed electric weight), stopped power supply by control system 3 control electrokinetic cells 1, and by metal-air battery 2 power supplies.
