Abstract
The utility model relates to an energy storing system of a small-sized electric vehicle, which comprises a power supply, a controlling panel, a converting/controlling device and a motor, wherein the power supply is a super capacitor set which is formed by that at least two simplex capacitors which are provided with integrated voltage equalizing circuits are connected in series / parallel; the super capacitor set is connected with the converting/controlling device through the controlling panel; the converting/controlling device is respectively connected with the super capacitor set and the motor. The utility model solves the problem that the energy storing system has long charging time, short circulating service life, high cost of use and maintenance and low capacity usage ratio; the utility model is suitable for small-sized electric vehicles such as a freight vehicle in a stop, a tourism vehicle, a golf vehicle, a sport vehicles in a ball field, etc.
Description
One, technical field:
The utility model relates to a kind of electric vehicle power system, particularly a kind of closed-centre system that is applied to small-sized electric car.
Two, background technology:
As everyone knows, the gordian technique of the restriction electric vehicle marketization is power supply.Storage battery is because unit volume energy stored height becomes the first-selected object of vehicle design.Yet, the deadly defect of storage battery is its horsepower output deficiency, because at some special occasions (for example under the abominable condition of service such as vehicle launch, climbing), short time, high-power output was essential, and concerning storage battery, under this condition, have to stand the impact of unconventional big multiplying power discharging, this is to being that the battery of mechanism is fatal with the Faradic electricity charge transfer reaction: because course of reaction must be followed mass-transfer reaction, battery age will sharply descend, and be difficult to satisfy the requirement of designer to battery cycle life.And for small-sized electric vehicles such as station transport truck, tour bus, Caddy, court moving vehicles, though storage battery can satisfy the peak power of vehicle to power supply in design, volume will be too huge, and storage battery cost proportion increases.And because peak power is only used at special occasions, this certainly will cause the energy dissipation of storage battery.Battery charge overlong time in addition is usually above 30 minutes.
Three, utility model content:
Technical problem to be solved in the utility model is: the automobile-used capacity usage ratio height of a kind of small-sized electric is provided, recycles the closed-centre system of long, exportable different capacity of life-span.
The utility model is achieved like this: it comprise power supply, control panel, conversion controller, motor, it is characterized in that: the power supply electrochemical capacitance group that the monomer electric capacity series/parallel of being furnished with integrated voltage balance circuit is formed of serving as reasons at least two, described electrochemical capacitance group by control panel with the conversion controller be connected, described conversion controller be connected with described electrochemical capacitance group, motor respectively.
Adopt the utility model, each electrically-charged time is decreased to 10～15 minutes, has realized promptly filling promptly using; Electrochemical capacitance was hit very for a short time when needs such as vehicle launch were high-power, have long life, complete non-maintaining characteristics, had exempted the increase that the user changes the use cost that battery brings; When vehicle is in brake and stops zero load, energy can be reclaimed, thereby be improved energy utilization ratio, really realize energy-conservation.
Four, description of drawings:
Accompanying drawing the utility model energy storage principle figure
Five, the specific embodiment:
With reference to the accompanying drawings, in the closed-centre system of small-sized electric car, the electrochemical capacitance group by control panel and conversion controller is connected, change controller be connected with motor M, electrochemical capacitance group respectively, the electrochemical capacitance group is made up of at least two monomer electric capacity series/parallels of being furnished with integrated voltage balance circuit.When battery-driven car on flat road during cruising, the electrochemical capacitance group is in conventional discharge regime, control panel instant recording and feed back situations such as electricity consumption and load.When battery-driven car in brake or stop when unloaded, conversion/controller is converted to electric energy with the mechanical energy of motor, and is stored in the electrochemical capacitance group; When battery-driven car startup and acceleration, the electrochemical capacitance group can provide the power density of 1000～1500W/kg, and the conversion/controller output stable energy by being attached thereto, and quickens to rotate with drive motor M, and pick-up time is 2～4 seconds.Adopt a kind of small-sized electric car of the present utility model, its oad is 3760 * 1470 * 1860mm
3The operating voltage range of the electrochemical capacitance group of its outfit is 36～54V, electrostatic capacity is 10000F, and wherein monomer electric capacity can be the combination of nickel oxide/carbon mixed type electrochemical capacitance or carbon/carbon double electrode layer electrochemical capacitance or nickel oxide/carbon ultracapacitor and carbon/carbon double electrode layer electrochemical capacitance.Equip the battery-driven car of this electrochemical capacitance group, speed per hour 20km/h, 40 kilometers of continual mileages, 20%, charging duration of hill climbing ability only need 10～15 minutes.
Claims (2)
1, a kind of closed-centre system of small-sized electric car, comprise power supply, control panel, conversion controller, motor, it is characterized in that: the power supply electrochemical capacitance group that the monomer electric capacity series/parallel of being furnished with integrated voltage balance circuit is formed of serving as reasons at least two, described electrochemical capacitance group by control panel with the conversion controller be connected, described conversion controller be connected with described electrochemical capacitance group, motor respectively.
