China takes much count of cleaning always, the exploitation of efficient automobile technology.Electric automobile is mainly containing fuel cell car, hybrid vehicle, 3 kinds of technology of pure electric automobile after being put into country's 863 great special projects aspect the car load exploitation.With respect to hybrid vehicle and fuel cell car, pure electric automobile has the advantage of self.Pure electric automobile replaces oil-burning machine with motor, and noise is low, pollution-free, and space that motor, oil plant and drive system account for less and weight can be in order to the demands of balancing battery; And because of using single electric energy, electric-control system is compared hybrid electric vehicle and is greatly simplified, and has reduced cost, but the also part price of balancing battery.And the battery of pure electric vehicle can utilize the cheapness " paddy " of electrical network to charge at night, and the peak-paddy that can stabilize electrical network is poor.For the car owner, utilize the cheapness " paddy " of count by time sharing, reduce operating cost.In a word, to the country, to electrical network, to environment, to the user, all be interests the more.
Now, along with the increasing of China to the pure electric automobile R﹠D intensity, China's pure electric automobile is very ripe technically.First pure electric automobile F3e of BYD development exposes in Beijing International Auto Show in 2006.It is introduced that the F3e F-Zero reaches 150 kilometers, the 0-100km/h accelerating time needed only 13.5 seconds, hundred kilometers power consumptions 12 degree, and once charging back distance travelled reaches 350 kilometers.Although China's pure electric automobile technology is very ripe, pure electric automobile industrialization, popularization widely also some concrete problem need to solve:
1, the charging difficulty is the greatest problem that the pure electric automobile industrialization faces.Can be full of 70% electricity in 10 minutes at electric automobile charging station, but the quick charge meeting reduces the useful life of battery, the consumer will check for the battery that has reduced useful life, can not accepted by consumers in general.And use the common power charging in family or parking lot, approximately wanted just can all be full of in 20 hours for 220 volts.
For solving the difficult problem of charging, pure electric automobile can be purchased the pattern that the process simulation of changing battery is built up the fair deal of finished product oil, promptly the motor vehicle energy is supplied with the electric automobile electrical changing station network system of trading system." fill " with " changing " replacement, give the third party charging work professional and that waste time and energy and bear.Just electric energy is not directly downloaded from electrical network and is sold to the pure electric automobile user, but through the aspect of power battery pack charging is sold.
2, the pattern that needs a kind of fair deal for this novel marketing method, need storage battery will measure and show use, the loss situation of energy clearly as the carrier of electric energy, thereby the electric automobile user is by paying power consumption, and charging station is by making the power consumption charge.
Summary of the invention
In view of the foregoing, the purpose of this utility model provides a kind of new-type pure electric automobile that meets and changes fast, the storage battery that makes power consumption accurately measure and to show.
The utility model achieves the above object by following structure: the utility model is a kind of intelligent accumulator of power consumption that shows, it is characterized in that embedding on the storage battery intensity amount, calculate, store and be shown in the intelligent apparatus of one, this intelligent apparatus is by current sampling circuit, the A/D change-over circuit, single chip circuit, LCD display and CAN bus module constitute, the output signal of current sampling circuit is delivered to the A/D change-over circuit, A/D change-over circuit signal output part is connected with singlechip chip, the single chip circuit signal output part is connected with the CAN bus module with LCD display respectively, the CAN bus module has the low electric weight indicator light of low electric weight alarm signal output ends and bridge panel board to be connected, and the CAN bus module is connected with showing the zero clearing operating key.
The operation principle that embeds the intelligent apparatus on the storage battery in the utility model is: singlechip chip is gathered current data by the Acquisition Circuit fixed number of times each second ground that makes power consumption, and it is averaged, obtain the average use electric current of each second, again the average current value of each second in the use form with integration is added up, obtain the ampere-hour number that storage battery accumulative total is used.Singlechip chip uses the ampere-hour number scale to record this accumulative total, and the driving LCD displays it.When electric weight was not enough, single-chip microcomputer was by the total line traffic control warning device of CAN driver.
Can be after charging station charges to used storage battery by the CAN bus with the zero clearing of power consumption that shows on the storage battery.
After the utility model is taked above technical measures, pure electric automobile with the power interface standardization of power accumulator, is consistent with the power interface of all pure electric automobile, and by smart circuit the power consumption of storage battery can be accurately measured and show.This measure not only makes the pure electric automobile makeup energy, it is more quick to change storage battery, and the power consumption of storage battery is come into plain view, and can not cause the dispute of any amount valency in the process of exchange.
The beneficial effects of the utility model are: solved pure electric automobile and replenished the problem that electric weight is measured in the novel trade mode of " filling " with " changing " replacement in the electric weight process with power accumulator, made the comprehensive market-oriented industrialization of pure electric automobile become possibility.
