Abstract
The utility model relates to the field of power electronic techniques and discloses a charging and billing device for an electric automobile. An intelligent terminal is embedded in charging facilities and comprises a processor I, a communication unit and a consumption processing unit. When the electric automobile is charged, accurate charging can be realized more scientifically and errors are reduced. The charging and billing device realizes accurate charging and saves the time at the same time. Moreover, by pertinently conducting relatively independent design on functions, the charging and billing device for the electric automobile guarantees the charging to be accurate, authoritative, safe and reliable, and facilitates energy saving and environmental protection.
Description
Technical field:
The utility model relates to the power technology field, is specifically related to a kind of charging accounting device that is used for electric automobile.
Background technology:
Along with the power automation degree constantly promotes, the supporting safe and reliable electricity consumption consuming method of electricity consumption facility has been proposed, guarantee requirement to the credibility of the accuracy of customer consumption and charge.The existing real-time electricity consumption charging method that is used at present on the electric automobile has generally adopted dependence metering outfit and general purpose controller to calculate the method for consumption information jointly.The drawback of this method is the part that the processing of consumption information belongs to the whole procedure flow process, and accuracy and reliability can't ensure, belong to a kind of " valuation " basically, and be extremely unreasonable, is unfavorable for energy-conserving and environment-protective.
The utility model content:
To the deficiency of prior art, the utility model provides a kind of charging accounting device that is used for electric automobile, solves present charging electric vehicle real-time consumption link and can't guarantee accuracy and reliability problems.
A kind of charging accounting device that is used for electric automobile that the utility model provides, its improvements are that said device comprises intelligent terminal, said intelligent terminal comprises processor I, communication unit and consumption processing unit; Said processor is connected with said consumption processing unit through said communication unit.
The charging accounting device of first preferred version that the utility model provides, its improvements are that said consumption processing unit comprises processor II, intelligent electric meter and storer; Said processor II is connected with said storer with said intelligent electric meter respectively.
The charging accounting device of second preferred version that the utility model provides, its improvements are that the model of said processor I is MCF52259.
The charging accounting device of the 3rd preferred version that the utility model provides, its improvements are that the model of said processor II is STM32F103.
With the prior art ratio, the beneficial effect of the utility model is:
The utility model realize the electricity consumption facility reliably, charge credibly, avoid the dispute that aspect electricity cost, produces.
The utility model realization of science metering of accurately charging has more reduced error.
When the utility model is realized accurate meterage, saved the time.
The utility model carries out the relatively independent design on the function targetedly, guarantees accurate, authoritative, the safety, reliable of charge metering, and helps energy-conserving and environment-protective.
Description of drawings
The intelligent terminal structural representation that Fig. 1 provides for the utility model.
The structural representation of the consumption processing unit that Fig. 2 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further to specify.
As shown in Figure 1, the intelligent terminal of present embodiment comprises processor I, communication unit and consumption processing unit; Said processor is connected with said consumption processing unit through said communication unit.
Processor I is used for reception/transmission information and shows, also according to the signal of said consumption processing unit, control is power supply externally.
Communication unit is connected between processor I and the consumption processing unit, plays communication role.
Consumption processing unit structural representation is as shown in Figure 2, and it carries out the power consumption metering and electricity cost is calculated, judges accounts information and account amount information, and provide corresponding signal, and processor I is according to this corresponding signal, and control is power supply externally; The consumption processing unit comprises processor II, intelligent electric meter and storer.Processor II is connected through communication interface with storer with intelligent electric meter respectively.Processor II is used to handle the intelligent electric meter number of degrees, adjusts the electricity charge that the user charges and uses; Storer is used for recording user password, accounts information; Intelligent electric meter is used to provide and measures the result accurately.
Concrete, a kind of as above-mentioned said practical approach that gets charging accounting device comprises the steps:
1) at the said intelligent terminal of the inner installation of charging electric vehicle facility;
2) user will consume password and input to said intelligent terminal;
3) the said processor I of said intelligent terminal receives said consumption encrypted message, and said consumption encrypted message is sent to said consumption processing unit through said communication unit;
4) the said consumption processing unit said consumption encrypted message that will receive is checked, if said consumption encrypted message is wrong, said consumption processing unit output is ceased and desisted order, and said processor I stops externally power supply and shows that input has false information according to ceasing and desisting order; If said consumption encrypted message correctly then carries out step 5);
5) said processor II checks the user account amount of money, if the account insufficient in amount that need supplement with money, said consumption processing unit output is ceased and desisted order, and said processor I stops externally power supply and shows that input has false information according to ceasing and desisting order; If said account amount of money abundance is then carried out step 6).
6) said consumption processing unit output startup command, said processor I obtains startup command through communication unit, and the account amount of money that the needs that provide according to the user are supplemented with money is exported corresponding electric weight.
Wherein, processor carries out information interaction with the consumption processing unit through communication unit, and both sides follow the communication protocol of agreement alternately.
The consumption processing unit is unique unit that consumption information is handled that carries out, and also is unique unit of importing with the process user accounts information that receives.After processor I obtains signal through communication unit, only after getting access to the account legal information, just carry out the electric weight transmission.
Should be noted that at last: combine the foregoing description only explain the utility model technical scheme but not to its restriction.Under the those of ordinary skill in field be to be understood that: those skilled in the art can make amendment or are equal to replacement the embodiment of the utility model, but these modifications or change are all among the claim protection domain that application is awaited the reply.
