Working process of the present invention is following:
It is main that the power-supply system of the super capacitor battery-driven car based on RFID of the present invention adopts the lithium cell group, and super capacitor is auxilliary.Mix in the battery-driven car that uses at super capacitor and lithium cell group, charger adopts microcontroller chip, takes the pulse control mode charging; And utilize the Single-chip Controlling charging current, can reach efficient fast charge, when brake energy reclaims simultaneously; Energy all replenishes to super capacitor, in order to using next time.
The power of motor is mainly provided by battery pack and super capacitor jointly.Ultracapacitor quickens in the startup of battery-driven car, does work during upward slope, and battery pack is worked on mild road, and the two complements each other.Conversion between the two is to read the two electric current through being embedded in RFID label in the battery case, voltage, and information such as dump energy send to the RFID reader in the controller for electric vehicle with these information.Controller for electric vehicle receives relevant information; Starting, when the grade of quickening to go up a slope need switch to super capacitor, judging whether super capacitor has enough electric weight earlier; If have then switch to super capacitor work; If the electric weight of super capacitor is not enough, then continue by battery-powered, super capacitor carries out oneself's charging in the way that bicycle is advanced.
Compared with prior art, the present invention has following beneficial effect:
The hybrid power source that the power-supply system of the super capacitor battery-driven car based on RFID of the present invention has used lithium cell group and super capacitor to form; And realized the utilization of making a concerted effort of two power supplys through Based Intelligent Control; Increased the service life of power-supply system, actual application prospect is wide.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification sheets, below with preferred embodiment of the present invention and conjunction with figs. specify as after.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below with reference to accompanying drawing and combine embodiment, specify the present invention.
Referring to shown in Figure 1; A kind of power-supply system of the super capacitor battery-driven car based on RFID; It comprises that one is used to provide the lithium cell group 101 and of main power supply to be used to provide the super capacitor of accessory feed to form 102; Said lithium cell group 101 is formed 102 with said super capacitor and is formed a hybrid power source 1, and said hybrid power source 1 connection one is used to read said lithium cell group 101 and forms 102 electric current, the battery data acquisition module 2 of voltage and dump energy information with said super capacitor; Said battery data acquisition module 2 connects a RFID label 3, and the information that said battery data acquisition module 2 collects sends through said RFID label 3; Comprise that also one is used to drive, control the controller for electric vehicle 4 of motor rotation; Said controller for electric vehicle 4 comprises that one is used to judge the power information of hybrid power source and switches the control module 401 of primary and secondary power power supply, and said control module 401 is connected with one and is used to receive the RFID reader 402 from the information of said RFID label 3 transmissions.
Further, said controller for electric vehicle 4 also is connected with one and is mainly used in the display panel 5 that shows the speed of a motor vehicle and power supply situation.
The principle of work of present embodiment is following:
Controller for electric vehicle comes the moving velocity of control vehicle through the control motor speed.Present embodiment adds RFID reader 402 on the conventional electric-powered vehicle controller; Mainly be used for reading the electric current of lithium cell group and super capacitor in the battery case; Information such as dump energy are when the battery-driven car startup, in the time of upward slope or acceleration; Controller for electric vehicle 4 is through the electric current of the super capacitor 102 that reads; Information such as dump energy judge whether to switch, and having enough electric weight like super capacitor 102 is super capacitor 102 with current powershift then, otherwise still uses lithium cell group 101 as the dynamically working power supply.In addition, RFID label 3 sends to controller for electric vehicle 4 with the sequence number of lithium cell, and controller for electric vehicle 4 receives behind the lithium cell sequence number with self sequence number and is complementary, could drive motor after mating successfully.The control if battery-driven car is opened under improper situation; Controller for electric vehicle 4 can not wake the RFID label 3 in the battery case up; Under the unsuccessful situation of sequence numbers match, controller for electric vehicle 4 can't drive motor, and this method has improved the anti-theft effect of battery-driven car greatly.
After the sequence numbers match success of the sequence number of controller for electric vehicle 4 and lithium cell, controller for electric vehicle 4 drive motor normal operation.RFID label 3 in the RFID reader 402 timing wake-up battery cases in the controller for electric vehicle 4 reads the electric current of lithium cell group 101, voltage, and information such as dump energy, through the wireless display panel 5 of passing to headstock, the condition of service of prompting user battery.This wireless method makes that the design of line electricity motor-car is light and handy more flexibly.
When battery breaks down; The maintainer can read the relevant use information of battery through RFID reader 402, and like the battery first charge-discharge time, battery has discharged and recharged number of times; The battery current electric quantity; And records such as some basic fault information such as overcurrent, through these the record maintainer can judge which type of state this battery is in, be can keep in repair or service life to changing battery again.This method has avoided battery more being changed as waste product once using, and can reuse through simple maintenance at battery in some cases.Improved the mea life of battery so greatly, alleviated the pollution of battery to a certain extent environment.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
