Description

Electric vehicle charging and billing method using cap separation meter reading {ELECTRIC VEHICLE CHARGING AND BILLING METHOD}

The present invention relates to a charging and billing method for an electric vehicle, and more particularly, to a charging method for an electric vehicle receiving charging power using a mobile charger at home or at a company.

As the spread of electric vehicles (EVs) around the world expands, the need to build a charging infrastructure is growing. The charging infrastructure consists of a charger, operating system, electrical equipment, communication equipment, and additional services, and collectively refers to tangible and intangible facilities, equipment, and S/W that the charger goes through in the process of supplying electric power to electric vehicles.

There are two types of charging methods: slow charging, which is charged by supplying 220V AC power, and rapid charging, which is charged by supplying high-voltage direct current. For slow charging, you can use a fixed charger installed in a dedicated parking space or a portable charger that connects to a general power outlet to charge.

A fixed-type charger requires a dedicated parking space to install the charger, but its use is not high due to domestic residential conditions, where the proportion of apartment houses is higher than that of single-family houses. On the other hand, portable chargers have the advantage of being able to be charged by connecting them to a power outlet provided in a public parking lot at any time while carrying them in a vehicle, and thus, the recent spread of mobile chargers is increasing.

However, in order to build an electric vehicle charging infrastructure using such a mobile charger, the progressive tax and challenge problems must be resolved. That is, when the charger owner connects the charger to any power outlet to charge the electric vehicle, the corresponding charging power must be deducted from the total power used by the customer who supplied the power, and at the same time, the corresponding charging power is provided to the charger owner or contractor separately. should be charged

Registered Patent No. 10-1448612 discloses a charging system for charging an electric vehicle to solve such a problem. However, the above registered patent measures the amount of power used for charging electric vehicles by the operator who sells and manages the mobile charger, not the power company, and transmits the measured amount of power to the power company. There is a possibility of damage or manipulation of related data, which can be a factor that lowers the reliability of the electric power company's billing.

The technical problem to be solved by the present invention is to propose an electric vehicle charging and billing method in which the electric power company directly reads the electricity consumption of the consumer and the charging power consumption of the electric vehicle, respectively, and charges based on this without a separate operator. .

The present invention for solving the above technical problem is a charging and billing method for an electric vehicle receiving charging power from a customer through a mobile charger, the method comprising: connecting a magnetic field installed in the mobile charger to a remote meter reading server; obtaining a maternal device ID for identification of a maternal device connected to an outlet to which the magnetic field supplies the charging power; receiving, by the remote meter reading server, magnetic meter reading data including a magnetic field power consumption amount, a magnetic field ID, and the maternal instrument ID by reading the magnetic field; determining, by the remote meter reading server, whether to permit the use of electricity for charging the electric vehicle; and charging, by the remote meter reading server, the power used by the consumer and the charging power of the electric vehicle, respectively, by using the magnetic field meter reading data.

According to the electric vehicle charging and billing method according to the present invention, the electric power company directly reads the magnetic field built into the mobile charger to collect information such as the amount of electricity and bills based on this, so that electricity charged to consumers and electric vehicle owners, respectively It has the effect of enhancing trust in the rate.

In addition, as the power company directly contracts with the mobile charger or electric vehicle owner, there is no need for a separate operating operator to be involved in charging power for charging, thereby simplifying the overall billing system.

Referring to FIG. 2 , when power is first supplied to the mobile charger 200 for charging the electric vehicle battery, the mobile charger 200 sends a remote meter reading server connection request message to the remote meter reading server 300 for connection with the remote meter reading server. to (S201).

At the same time or sequentially, for communication with the mother machine 100 to which an outlet to be supplied with charging power is connected, a mother machine connection request message is transmitted to the mother machine 100 (S202).

Thereafter, in response to steps S201 and S202, the mobile charger 200 may receive a mother machine connection response message and a remote meter reading server connection response message from the mother machine 100 and the remote meter reading server 300, respectively (S203). and S204).

When the mother machine 100 and the mobile charger 200 are connected in step S204, the mobile charger 200 may transmit a mother machine information request message to obtain the mother machine information from the mother machine 100 (S205).

The mother machine information means information including a mother machine ID for identifying the mother machine 100, and the mother machine 100 transmits a mother machine information response message in response to the mother machine information request message. The mother machine ID may be provided to the magnetic machine 250 (S206).

According to an embodiment, the mother line connection response message of step S204 may include the mother line information, and accordingly steps S205 and 206 may not be performed.

On the other hand, after the mobile charger 200 is connected to the remote meter reading server 300, the remote meter reading server 300 may transmit a magnetic field meter reading data request message to the mobile charger 200 to collect the magnetic field meter reading data ( S207).

Thereafter, the mobile charger 200 may wait for a connection response from the mother machine 100 and the remote meter reading server 300 (S303, S304), and when a connection response is not received for a predetermined time, a predetermined number of times (n) The connection can be requested again until (S305, S306).

Connection responses received from the mother machine 100 and the remote meter reading server 300 may be merged (S307), and as the connection response is processed, the mobile charger 200 requests the mother machine information from the mother machine 100 (S308), and at the same time, the remote meter reading server 300 is in a state of waiting for meter reading data request and waiting for electricity use permission (S309 and S310).

After the request for maternal device information in step S308, the mobile charger 100 is in a waiting state for receiving maternal device information (S311), and when the maternal device information is not received from the maternal device 100 within a certain period of time, it is received If not, the maternal information may be requested again up to a certain number of times (m) (S312).

The meter reading data request standby state of step S309 may continue until a meter reading data request is received from the remote meter reading server 300 (S313), and when the mobile charger 200 receives the meter reading data request, a response to the meter reading data request is received In this way, the mother machine information received in step S311 along with its own magnetic meter information may be transmitted to the remote meter reading server 300 (S314).

In addition, in the electricity use permission standby state of step SS10, the mobile charger 200 may wait for electricity use permission from the remote meter reading server 300 for a predetermined standby time (s) (N, S316 of S315). On the other hand, when receiving permission to use from the remote meter reading server 300 within the standby time (s) (Y in S316), the mobile charger 200 can start charging by supplying electric vehicle power, and charging is performed according to the set schedule. Charging may proceed until completion (S317, S318).
