Description
Technical field
The present invention relates to the battery of electric vehicle system that a kind of battery increases journey.
Background technology
The appearance of battery-driven car is early than fuel-engined vehicle, but because the reasons such as its mileages of continuation is short, charging is inconvenient are not popularized so far yet.At present, due to factors such as oil crises, environmental pollutions, new-energy automobile is all being greatly developed in countries in the world, and the pure electric vehicle of zero-emission is one of new-energy automobile of giving priority to.
The advantage of pure electric vehicle is apparent: zero-emission, and over-the-road expense is low, and noise is little, natural automatic catch, acceleration capability is good etc.But major defect is: mileages of continuation is short, and charging is inconvenient, on the high side etc.About solving mileages of continuation and charging problem, many modes that solve of attempting are arranged at present, there is larger dispute, still without gratifying solution.
One of solution is the energy density that increases substantially battery.Electrochemical system for electrokinetic cell mainly contains LiFePO4, ternary material, LiMn2O4 etc. at present.Still there is certain problem at present in the high temperature cyclic performance of LiMn2O4, and also there is hidden danger in the safety performance of ternary material, and present stage most widely used LiFePO4 have the problem that energy density is slightly low.That is to say, solve the short problem of battery-driven car mileages of continuation by the energy density that improves significantly battery at short notice and still have very large difficulty.
As if lithium titanate battery can fast charge, also can solve the problem that mileages of continuation is short and charging is inconvenient of pure electric vehicle.But the energy density of lithium titanate battery is too low, fast charge simultaneously is too large again to the impact of electrical network, so scheme is also undesirable.
Also having a kind of is exactly to change power mode: utilize the quick-replaceable battery to solve the mileages of continuation problem of pure electric vehicle.But this pattern, due to reasons such as electrical changing station laid down cost are too high, the plugging mode design is unreasonable, the manned vehicle structural change is too large, promotes effect unsatisfactory.
Utilize fuel engines to battery charged (being referred to as extended-range electric vehicle) be also a kind of method that solves pure electric vehicle mileages of continuation problem.But this method and technology is too complicated, and the car load cost is high, simultaneously neither zero-emission, so neither a kind of desirable solution.
Summary of the invention
The technical problem to be solved in the present invention is to provide the battery of electric vehicle system that a kind of battery increases journey.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of battery increases the battery of electric vehicle system of journey, comprise the main battery module, increase journey battery module, electric machine controller and shifter, the main battery module with increase the journey battery module and be connected with electric machine controller respectively by shifter.
As preferably, the main battery module comprises master battery pack and corresponding dynamic wire harness and signal wire harness; Master battery pack and corresponding dynamic wire harness and signal wire harness form one independently drive energy system is provided.
Preferred as another, increase the journey battery module and comprise auxiliary battery banks and corresponding dynamic wire harness and signal wire harness; Auxiliary battery banks and corresponding dynamic wire harness and signal wire harness form another independently drive energy system is provided.
As further preferred, shifter is automatic switching control equipment; Automatic switching control equipment comprises master switching switch and auxiliary control change-over switch; Automatic switching control equipment directly is connected the dynamic wire harness cathode output end of main battery module, the dynamic wire harness cathode output end parallel connection that increases the journey battery module afterwards with electric machine controller cathode output end mouth; The dynamic wire harness cathode output end of main battery module, the dynamic wire harness cathode output end that increases the journey battery module are connected with electric machine controller cathode output end mouth with the auxiliary control change-over switch by master control respectively; The master switching switch is controlled its break-make by main system CCU; The auxiliary control change-over switch is controlled its break-make by increasing journey system CCU; Automatic switching control equipment is switching main battery module and the signal wire harness that increases the journey battery module in switching main battery module and the dynamic wire harness that increases the journey battery module.
Also have one preferably, shifter is manual switching device; But manual switching device is by the plug switching main battery module of plug and increases the positive-negative input end that the journey battery module is connected respectively to electric machine controller.
The invention has the beneficial effects as follows:
Adopt battery to increase the novel concept of journey, designed rational battery module and failure-free connection and switching mode fast, thereby really solved the mileages of continuation problem of battery-driven car, for road has been paved in the real marketization of pure electric vehicle.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the catenation principle figure that battery of the present invention increases the battery of electric vehicle system embodiment of journey.
Fig. 2 is the control principle drawing that battery of the present invention increases the battery of electric vehicle system embodiment of journey.
The specific embodiment
As shown in Fig. 1, the electrical source of power of battery-driven car is by the main battery module and increase the journey battery module and form, the basic configuration module that wherein the main battery module is battery-driven car, by scattering device at vehicle body main power source battery separately in series, for the daily basic use of battery-driven car; The apolegamy module that to increase the journey battery module be battery-driven car or increase the journey module, by scattering device at vehicle body auxiliary power-supply battery separately in series, in the situation that the main battery module has consumed electricity to the battery-driven car power supply, realize increasing the purpose of the mileages of continuation of battery-driven car.Above-mentioned main battery module and increase the journey battery module and be connected respectively to the positive-negative input end of electric machine controller by shifter.
As shown in Figure 2, when controller for electric vehicle monitors the main battery module, consumed when electricity, output signal, now start to start and increase the journey battery module and power to battery-driven car.Its handoff procedure can complete by intelligent automatic switching control equipment.Increase the journey battery module and comprise auxiliary battery banks and corresponding power line and signal wire (SW), wherein the corresponding wire harness of power line, signal wire (SW) and vehicle body can carry out fast and reliable and patches, make increase the journey battery module can the fast and reliable replacing.Consumed when electricity increasing the journey battery module, what can fast speed more renew increases the journey battery module, to reach the purpose that increases the battery-driven car course continuation mileage.
