Abstract
The invention discloses an electric and oil-electric hybrid vehicle driving and sustaining two-level battery power supply system, which comprises a battery pack and an energy storage device, wherein the energy storage device is used for supplying a large driving current in short time; the battery pack and the energy storage device are connected in parallel to supply power to the outside; and the battery pack can charge the energy storage device. By adoption of the technical scheme, the problems of large current required by driving of a vehicle and power supplying during normal running can be solved just by combining the conventional ordinary batteries.
Description
Technical field
The present invention relates to that a kind of electronic, oil electric mixed dynamic automobile drives, continuation of the journey two-stage battery power supply system; Relate to particularly that a kind of electronic, oil electric mixed dynamic automobile drives, continuation of the journey two-stage battery power supply system, the problem of supplying power when required big electric current and cruising when it can solve automobile simultaneously and drives.
Background technology
Along with people's is to the pay attention to day by day of environmental problem, and various new-energy automobiles continue to bring out out, and this will play important effect to the crux problem that solves china natural resources relative shortage and lot of consumption.Wherein hybrid vehicle relies on its fuel-economy performance high, and the superior advantage of rideability, is more and more accepted by masses.Though the engine of hybrid vehicle will use fuel oil,, can reduce oil consumption because the auxiliary of electro-motor arranged; Briefly; Compare with onesize automobile exactly, fuel cost can reduce relatively, the more important thing is that it has alleviated the pollution to surrounding environment greatly.
But hybrid vehicle need provide a big drive current at short notice when starting, and all very high for the production and the requirement of this battery, the cost of battery management system also can correspondingly increase.To the problems referred to above, we adopt the classification electric power system to solve the big electric current required when driving and the power supply of cruising, in the useful life that can improve battery greatly, also reduce volume of battery simultaneously, and reduce cost.
Summary of the invention
Technical problem to be solved by this invention is; Provide that a kind of electronic, oil electric mixed dynamic automobile drives, continuation of the journey two-stage battery power supply system; Its need carry out certain combination to existing common batteries, the required big electric current and the powerup issue of cruising in the time of just can solving automobile and drive.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of electronic, the oil electric mixed dynamic automobile drives, continuation of the journey two-stage battery power supply system, comprising: battery pack; The constant current control unit is used to guarantee that battery pack externally provides constant current; Energy storage device is used for providing at short notice a big drive current; Wherein, the parallelly connected externally power supply of battery pack with energy storage device, battery pack can be charged to energy storage device.
The energy density of the energy storage device that preferably, described electronic, oil electric mixed dynamic automobile drives, continuation of the journey two-stage battery power supply system adopts is lower than battery pack but its power-discharging density is higher than battery pack.
Preferably, said battery pack is made up of lithium ion battery.
Preferably, said energy storage device is that lead-acid battery, Ni-MH battery, nickel-cadmium cell, super capacitor are a kind of in farad capacitor or the dynamic lithium battery.
Advantage of the present invention is; Disclosed electronic, oil electric mixed dynamic automobile drives, continuation of the journey two-stage battery power supply system adopts the parallelly connected externally power supply with energy storage device of battery pack; Battery pack can be charged to energy storage device, and energy storage device can provide a big drive current at short notice, therefore; Only need carry out certain combination the problem of supplying power when required big electric current and cruising in the time of just can solving automobile and drive to existing common batteries.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain:
Fig. 1 is electronic for the present invention, the oil electric mixed dynamic automobile drives, the overall structure sketch map of continuation of the journey two-stage battery power supply system.
Embodiment
For further disclosing technical scheme of the present invention, convenient your auditor's censorship is described with reference to the accompanying drawings execution mode of the present invention now:
Like Fig. 1, for electronic, the oil electric mixed dynamic automobile that the present invention set forth drives, the overall structure sketch map of continuation of the journey two-stage battery power supply system, wherein, comprising: battery pack 4 is used for the power supply of automobile normal running; Constant current control unit 3 is used to guarantee that battery pack 4 externally provides constant current; Energy storage device 2 is used for providing at short notice a big drive current; Wherein, battery pack 4 and energy storage device 2 parallelly connected externally power supplies, battery pack 4 can be charged to energy storage device 2 when idle; The energy density of energy storage device 2 is lower than battery pack 4 but its power-discharging density is higher than battery pack 4.
Said battery pack 4 is made up of lithium ion battery; Said energy storage device 2 is a kind of in farad capacitor or the dynamic lithium battery for lead-acid battery, Ni-MH battery, nickel-cadmium cell, super capacitor.
Followingly working condition of the present invention is described with reference to Fig. 1:
At first, battery pack 4 and energy storage device 2 are charged, when automobile start, pass through supply line's 1 driven in common automobile after charging electricity by battery pack 4 and energy storage device 2; Behind the automobile start since the energy density of energy storage device 2 power-discharging density is greater than battery pack 2 less than battery pack 4, so the electric energy that stores in the energy storage device 2 can be exhausted very soon; After battery pack 4 and energy storage device 2 stop the automobile power supply, begin energy storage device 2 is charged with energy storage device 2 parallel battery 2, prepare against the usefulness of driven in common automobile once more.
More than, basic design of the present invention and basic principle have been set forth through introduction to listed execution mode.But the present invention never is limited to above-mentioned listed execution mode; Every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on technical scheme of the present invention of change; Such as; Under the situation identical with connected mode of the present invention, just use dissimilar battery pack 4 instead and realize such scheme with energy storage device 2, all should belong to protection scope of the present invention.
