Description
Technical Field
The invention relates to the field of new energy automobiles, in particular to a new energy automobile battery replacement charging method.
Background
At present, new energy vehicles increasingly enter the public life, but the development of new energy electric vehicles is still restricted due to slow charging and inconvenient charging of the new energy vehicles at present. The new energy automobile power changing business is undoubtedly a technology for promoting the new energy automobile to replace the fuel oil automobile.
The existing charging mode for quickly changing the battery of the new energy automobile is mostly divided into two types: one is to calculate based on the electricity consumption of the user, i.e. the total charge is obtained by multiplying the electricity consumption of the user by the unit price electricity charge; the other method is to calculate the driving mileage of the vehicle, namely to multiply the driving mileage of the user by the unit price to obtain the total cost. Both of these charging methods have drawbacks and vulnerabilities.
In the method adopting the first mode and taking the electric quantity as the calculation basis: firstly, calculating the difference value of the electric quantity through the initial electric quantity and the electric quantity during charging, then multiplying the difference value by the unit price of the electric charge, and adding the service charge to obtain the battery replacement charge which is paid by the customer. However, when the method is used for charging, the interference caused by self-charging of the client cannot be avoided. The existing power-change electric vehicle is provided with an emergency charging function for the battery in order to avoid the embarrassing situation that the power of the battery is insufficient and the power-change station cannot be found, so that a user can charge the battery by himself. However, after the user charges, the electricity charge cannot be accurately calculated, meanwhile, the user self-charges and is influenced by the charging equipment, most of the existing charging equipment is a direct-current quick-charging pile instead of a slow-charging equipment suitable for replacing a battery, so that the battery is also lost in the charging process, the service life of the battery is influenced, and the loss cannot be made up.
The method adopting the second mode and taking the mileage as a calculation basis comprises the following steps: the mileage difference is calculated through the initial mileage and the mileage during charging, and the cost due to the customer is calculated according to the mileage difference before and after battery replacement. This approach has two vulnerabilities: firstly, a user can perform private scheduling, and the mileage on the electric vehicle is adjusted to obtain a small mileage so as to save the electric charge; in addition, if in the use process, the battery is also consumed under the condition of road condition congestion, but the driving mileage is not increased, and the air conditioner is started, so that the electricity consumption is caused, and the mileage does not increase.
Therefore, a reasonable charging mode is urgently needed to charge the charging for the power-change electric vehicle.
Disclosure of Invention
The invention aims to provide a new energy automobile battery replacement charging method to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
a new energy automobile battery replacement charging method is characterized in that:
the method comprises the following steps:
(1) detecting the current battery ratio of the battery, subtracting the current battery ratio from the total battery ratio to obtain the battery ratio of the user, and multiplying the battery ratio of the user by the unit price of electric quantity to obtain the electric charge, wherein the electric charge = (total battery ratio-battery ratio used) × the unit price of electric quantity;
(2) detecting whether the battery is overcharged by a user in the use, and if the battery is not overcharged, charging cost is set for reinforcing electric charge;
(3) if the user is detected to be overcharged in the step (2), the battery replacement cost is the sum of the electric charge plus the loss plus the fixed service cost, namely the battery replacement cost = the electric charge plus the loss plus the fixed service cost; the loss is the sum of a ratio of a battery consumed before the user is charged, a ratio of a battery charged by the user and a ratio of a battery consumed after the user is charged multiplied by a loss unit price, namely loss = (the ratio of the battery consumed before the user is charged + the ratio of the battery charged by the user + the ratio of the battery consumed after the user is charged) is the loss unit price, the ratio of the battery consumed before the user is charged = a total battery ratio-a battery ratio before the user is charged, the ratio of the battery charged by the user = a battery ratio after the user is charged-a battery ratio before the user is charged, and the ratio of the battery consumed after the user is charged = a battery ratio after the user is charged-a current battery ratio;
the unit price of the electric quantity is the actual unit price of the electric power consumption at the current position;
the fixed service charge = total price of the current power station changing equipment, depreciation rate and service life times of the power station changing equipment;
the loss unit price = charging module total price of the current power conversion station × [ depreciation rate ]/[ charging module service life times of the current power conversion station + battery pack total price ÷ [ battery pack capacity ]/[ battery pack service life times ].
Further, in step (1), the total mileage of the user in the month is detected, and if the total mileage of the user in the month is greater than the preferential mileage value, the electricity fee = (total battery ratio-used battery ratio) × electricity unit price = preferential proportion.
Compared with the prior art, the invention has the beneficial effects that:
the calculation of the battery replacement cost is not carried out only by using the electric quantity by the user or taking the driving mileage of the vehicle as a basis, but the final battery replacement cost is obtained by adding the loss to the electric charge calculated by using the electric quantity by the user, so that the error generated by calculating only by using the driving mileage is eliminated, and meanwhile, the loss cost of the battery for self-charging of the user is made up. The charging is reasonable, and meanwhile, the user is encouraged to change the battery in time when the battery is low in electric quantity, so that the battery is prevented from being lost due to self-charging, and the battery resource is wasted.
Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A new energy automobile battery replacement charging method comprises the following steps:
(1) detecting the current battery ratio of the battery, subtracting the current battery ratio from the total battery ratio to obtain the battery ratio of the user, and multiplying the battery ratio of the user by the unit price of electric quantity to obtain the electric charge, wherein the electric charge = (total battery ratio-battery ratio used) × the unit price of electric quantity;
(2) detecting whether the battery is overcharged by a user in the use, if not, charging fee is fixed service fee for reinforcing the electric charge;
(3) if the user is detected to be overcharged in the step (2), the battery replacement cost is the electricity charge plus the loss plus the fixed service cost, namely the battery replacement cost = the electricity charge plus the loss plus the fixed service cost; the loss is the sum of a ratio of a battery consumed before the user is charged, a ratio of a battery charged by the user and a ratio of a battery consumed after the user is charged multiplied by a loss unit price, namely loss = (the ratio of the battery consumed before the user is charged + the ratio of the battery charged by the user + the ratio of the battery consumed after the user is charged) is the loss unit price, the ratio of the battery consumed before the user is charged = a total battery ratio-a battery ratio before the user is charged, the ratio of the battery charged by the user = a battery ratio after the user is charged-a battery ratio before the user is charged, and the ratio of the battery consumed after the user is charged = a battery ratio after the user is charged-a current battery ratio;
the electricity unit price is the actual electricity unit price of the current position.
The fixed service charge = total price of the current power station changing equipment, depreciation rate and service life times of the power station changing equipment.
The loss unit price = charging module total price of the current power conversion station × [ depreciation rate ]/[ charging module service life times of the current power conversion station + battery pack total price ÷ [ battery pack capacity ]/[ battery pack service life times ].
The unit price of electricity near the current power change station is 1.2 yuan/kwh.
At present, the fixed service charge is calculated to be 12 yuan according to the total price, the depreciation rate and the service life times of the current power station changing equipment.
And calculating to obtain the unit cost of 0.3 yuan according to the total price and the depreciation rate of the charging module of the current charging station, the service life times of the charging module of the current charging station, the total price of the battery pack, the capacity of the battery pack and the service life times of the battery pack. The life of the battery is about 2000 cycles, the cost of each battery is about 2.5 ten thousand yuan, and the capacity of one cycle of the battery is about 42 degrees electricity, so the breaking loss of the battery is =25000 yuan ÷ 2000 ÷ 42 ≈ 0.3 yuan.
For example: the battery capacity is 43kwh, after a customer changes a new battery with 100% of electricity, the electricity is consumed to 50%, the electricity is automatically charged to 90%, then the electricity is discharged to 60%, and the electricity is changed when the customer comes to a battery changing station. The charge is as follows:
(1) electric charge = (total electric quantity value-current electric quantity value) electric quantity unit price
Namely: electricity charge = (100% -60%) 43kwh 1.2 yuan/kwh =20.64 yuan.
(2) Detecting whether the battery is overcharged by a user in the use;
(3) detecting that the user is overcharged, wherein the charging fee = the electricity fee + the loss fee + the fixed service fee
Loss = (100% -50%) 0.3+ (90% -60%) 0.3+12=36 yuan. Battery pack
The battery replacement cost =20.64 yuan +36 yuan +12 yuan =68.64 yuan
If the user only consumes 60% of the new battery with 100% of the electricity and does not perform self-charging in the middle, the charge is as follows:
battery replacement charge = electricity charge + fixed service charge =32.64 yuan
From the aspect of battery replacement cost, the battery which is consumed from 100% to 60% can be clearly seen, the cost difference is large when battery replacement is carried out, and the battery loss caused by self-charging of a user is made up from the difference. Simultaneously, the user can carry out more reasonable charging arrangement in the using process, and the self-charging is avoided as much as possible.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
