Abstract

OCR 10KL (11/03/2025) The electric vehicle charging system, equipped with an automatic meter reading (AMR) system and a prepaid electrical switch, consists of an electric vehicle charger (10) equipped with an automatic meter reading (AMR) unit (11) that reads the current flow to the load (LOAD) which is an electric vehicle, and an electrical switch (20) that commands the electrical switch (20) to open or stop the operation of the electrical switch to supply current to the load (LOAD) which is an electric vehicle. The first processing unit (1) will open the electrical switch (20) when prepaid is received, and the first processing unit (1) will close the electrical switch (20) when current flows through the automatic meter reading (AMR) unit (11) for the specified usage time and amount of money.

Claims (1)

OCR 10KL (11/03/2025) 1. The system of charging equipment for electric vehicles that is equipped with an automatic meter reading (AMR) system and a prepaid electrical switch has the following characteristics: The electric vehicle charging equipment (10) will have the structure of a cabinet, which will supply electricity to the load (LOAD) which is an electric vehicle. It has the special characteristic that the electric vehicle charging equipment (10) inside the cabinet structure will have an automatic meter reading (AMR) unit (11) installed. The automatic meter reading (AMR) unit (11) will be connected to the first processing unit (1) which is a computer program system that reads the value of the current flow that is supplied to the load (LOAD) which is an electric vehicle. Through the Automatic Metering (AMR) unit (11), the first processor (1) is connected to the electrical switch (20) and is responsible for instructing the electrical switch (20) to open to supply electricity to the electric vehicle load or close to stop supplying electricity to the electric vehicle load. The first processor (1) of the electric vehicle charger (10) has a first transceiver that communicates with the central processing unit (40) wirelessly. The central processing unit (40) has a second transceiver that communicates with the first processor (1) of the electric vehicle charger (10) wirelessly. The first and second transceivers communicate with each other via a central communication unit (DCU) (50). The central processing unit (40) has a second transceiver that communicates with the online payment system (60) wirelessly. The online payment system (60) has a third transceiver that communicates with the central processing unit (40) wirelessly. The electronic device (30) is connected to a second processing unit (2), which is a computer program connected to a fourth transceiver, which communicates with the online payment system (60) to make payments to the electric vehicle charging provider's wallet (10). The online payment system (60) notifies the central processing unit (40) that the payment has been successfully made and that the specified usage period has expired. The central processing unit (40) then notifies the first processing unit (1), which is connected to the electrical switch (20), which instructs the electrical switch (20) to open to supply electricity to the electric vehicle load or close to stop supplying electricity to the electric vehicle load. The first processing unit (1), which is connected to the automatic meter (AMR) unit (11), when electricity flows through the automatic meter (AMR) unit (11) for the specified usage period, the first processing unit (1) instructs the electrical switch (20) to close.
