In the above-described embodiments, multiple valuation time period can be comprised in tou power price table, each valuation time period prestores a tou power price, the all valuation time periods fallen in the time range of discharge and recharge are read from tou power price table, and read the tou power price prestored in each valuation time period, can calculate the discharge and recharge electricity price of electric automobile according to the tou power price that the valuation time period is corresponding, result of calculation is more accurate.
According to the above embodiment of the present invention, the discharge and recharge electricity price using tou power price and electricity to calculate electric automobile can comprise: the charge value obtaining electricity each valuation time period corresponding; Use the charge value of each valuation time period and tou power price to be weighted, obtain the discharge and recharge electricity price of electric automobile.
Particularly, after obtaining the charge value of the electricity of electric automobile under charge and discharge mode each valuation time period corresponding, the charge value of each valuation time period is multiplied with tou power price, obtain the discharge and recharge electricity price in each valuation time period, by the discharge and recharge electricity price in each valuation time period is added the discharge and recharge electricity price that can obtain electric automobile.
By the above embodiment of the present invention, calculate discharge and recharge electricity price according to each valuation time period fallen in the time range of discharge and recharge, the discharge and recharge electricity price of the electric automobile calculated more accurately rationally.
In an optional embodiment of the present invention, the tou power price table in electricity rate table set can be obtained by the tou power price table of Resident Electricity Price.
Such as, tou power price can be determined at Different periods by 0.8 times of Resident Electricity Price corresponding to this period.Table 1 comprises Resident Electricity Price, according to 0.8 times of Resident Electricity Price the first charging electricity price (tou power price namely in above-described embodiment) determined, electric automobile hundred kilometers cost and fuel vehicle hundred kilometers cost.
Wherein, electric automobile be full of electricity by single after electricity be 56kWh calculate, this electricity can make electric automobile during traveling 300 km, then electric automobile hundred kilometers of power consumption are about 19kWh, then can calculate electric automobile hundred kilometers cost by tou power price and hundred kilometers of power consumption; Regular fuel automobile is by traveling hundred kilometers of oil consumptions about 8 liters calculating, and by the calculation of price of up-to-date 97# gasoline, fuel-engined vehicle hundred kilometers of costs are 58.88 yuan.
As shown in table 1, is divided into the first period, the second period and the 3rd period the time of one day (24 hours), each period corresponding first charging electricity price all different.
Table 1
And for example, the second charging electricity price of the first period can be determined by 1.2 times of the first period Resident Electricity Price in the first period, determine the second charging electricity price of the second period in the second period by 1 times of the second period Resident Electricity Price, and determine the second charging electricity price of the 3rd period in the 3rd period by 0.8 times of the 3rd period Resident Electricity Price.Table 2 comprise Resident Electricity Price, according to Resident Electricity Price determination second charging electricity price (tou power price namely in above-described embodiment), electric automobile hundred kilometers spend and fuel vehicle hundred kilometers cost.
Table 2
For another example, on the basis of table 2, increase electric discharge electricity price, as determined the electric discharge electricity price of the first period in the first period by 1.5 times of the first period Resident Electricity Price, determine the electric discharge electricity price of the second period in the second period by 1 times of the second period Resident Electricity Price, and determine the electric discharge electricity price of the 3rd period in the 3rd period by 0.6 times of the 3rd period Resident Electricity Price.Table 3 comprise Resident Electricity Price, according to Resident Electricity Price determination second charging electricity price, according to the determination of Resident Electricity Price electric discharge electricity price, electric automobile hundred kilometers cost and fuel vehicle hundred kilometers cost.
Table 3
The first above-mentioned period can be 9:00-12:00 and 17:00-22:00; Second period can be 8:00-9:00,12:00-17:00 and 22:00-23:00; 3rd period can be 23:00-24:00 and 24:00-8:00.
