TH25460U - Charging equipment for electric vehicles equipped with Automatic Meter Reading (AMR) system and Prepaid Switch - Google Patents

Abstract

OCR 10KL (11/03/2025) The system of electric vehicle charging equipment equipped with an automatic meter reading system (AMR) and a pre-payment electrical system on/off switch (PREPAID) consists of an electric vehicle charging equipment (10) equipped with an automatic meter reading system (AMR) (11) that reads the flow of electric current supplied to the load (LOAD) which is an electric vehicle. The electrical system on/off switch (20) functions to command the electrical system on/off switch (20) to start or stop working to supply electric current to the load (LOAD) which is an electric vehicle. The first processing unit (1) will turn on the electrical system on/off switch (20) when there is a pre-payment (PREPAID) and the first processing unit (1) will turn off the electrical system on/off switch (20) when there is electric current flowing through the automatic metering unit (AMR) (11) according to the usage period according to the specified amount.

Claims (1)

OCR 10KL (11/03/2025) 1. The charging system for electric vehicles equipped with an automatic meter reading system (AMR) and a prepaid power switch consists of an electric vehicle charging device (10) in the form of a cabinet structure that supplies electricity to the load (LOAD) which is an electric vehicle. The special feature is that the electric vehicle charging device (10) has an automatic meter unit (AMR) (11) installed inside the cabinet structure. The automatic meter unit (AMR) (11) is connected to the first processing unit (1), which is a computer program system that reads the flow of electricity supplied to the load (LOAD) which is an electric vehicle. Through the automatic metering unit (AMR) (11), the first processing unit (1) will be connected to the electrical system on/off switch (20), which will command the electrical system on/off switch (20) to turn on the operation to supply electricity to the load (LOAD) which is the electric vehicle, or turn it off to stop supplying electricity to the load (LOAD) which is the electric vehicle. The first processing unit (1) of the electric vehicle charging device (10) will have a first transceiver that communicates with the central processing unit (40) via a wireless system. The central processing unit (40) will have a second transceiver that communicates with the first processing unit (1) of the electric vehicle charging device (10) via a wireless system. The first transceiver and second transceiver communicate with each other through a central communication unit (DCU) (50). The central processing unit (40) will have a second transceiver that communicates with the online payment system (60) via a wireless system. The online payment system (60) will have a third transceiver that communicates with the central processing unit (40) via a wireless system. The electronic device (30) is connected to the second processing unit (2), which is a computer program system connected to the fourth transceiver, which communicates with the online payment system (60) to make a payment to the wallet of the electric vehicle charging device provider (10). The online payment system (60) notifies the central processing unit (40) that the payment has been successful and the usage period has reached the specified amount. The central processing unit (40) then notifies the first processing unit (1) connected to the electrical system on/off switch (20), which commands the electrical system on/off switch (20) to turn on the operation to supply electricity to the electric vehicle load (LOAD), or to turn it off to stop supplying electricity to the electric vehicle load (LOAD). The first processing unit (1) connected to the automatic metering unit (AMR) (11), when the electricity flows through the automatic metering unit (AMR) (11) for the specified amount of usage period, the first processing unit (1) will command the electrical system on/off switch (20) to turn off.
