Improve Remote Monitoring and Reliability of EV Charging Piles with ICP DAS Intelligent CAN Bridge
ICP DAS I-2533 series CAN/CAN FD to Multi-mode/Single-mode Fiber Bridge receives data from electric vehicle (EV) charging infrastructure through the CAN bus and extends the communication distance via fiber optics. Subsequently, the I-2533 series transmits the data to the PISO-CAN200U series PCI Card, which the central controller is equipped with, using the CAN bus. The system allows management personnel to monitor the status of charging piles from a remote control center.
Introduction:
The South Korean government aims for nationwide installations of 300,000 to 400,000 EV charging piles over the next three years. With such a plan, the renewable energy market centered around charging piles, electric vehicles, and green power has drawn people’s attention.
In this case study, the customer is a well-known and major charging pile manufacturer and supplier in South Korea. Since the EV charging stations are scattered across the country, maintenance personnel have had to shuttle constantly between locations for fixed routine — equipment status checks. The customer hence adopts the ICP DAS EV charging pile monitoring solution to reduce the costs involved and efficiently deploy human resources. The maintenance personnel could remotely monitor each EV charging equipment’s status in real time. Besides, the data is now transmitted through fiber optics insusceptible to electromagnetic interferences, eliminating disturbances caused by electromagnetic fields generated by high currents used in charging piles and extending the communication distance.
ICP DAS EV Charging Pile Monitoring Solution
The data on the EV charging pile’s status is transmitted to ICP DAS I-2533 CAN to Multi-mode Fiber Bridge through the CAN bus and then sent to another I-2533 module via fiber optics and subsequently transmitted to the PISO-CAN200U-T PCI Card, which the central controller is equipped with, using the CAN bus again. The solution achieves remote monitoring, extension of communication distance using fiber optics insusceptible to electromagnetic interferences, and ensures reliable data transmission.
ICP DAS I-2533 CAN to Multi-mode Fiber Bridge can convert between the electrical CAN bus signal and fiber optics. By employing two I-2533 modules, the fiber optic interface of each I-2533 enables the connection of two CAN networks using the same or different baud rates. The module also supports CAN Specification, CAN 2.0A and CAN 2.0B, as well as connects up to 100 CAN devices.
When using the I-2533 module, the communication distance of the fiber optic is not affected by the baud rate on the CAN network, reaching a maximum distance of 2 kilometers. Suppose a severe error occurs on one CAN network, leading to the connected CAN devices’ communication failures. In that case, another CAN network will not be affected as the fiber optics are the transmission medium between the two CAN networks.
The I-2533 module provides the easy-to-use message filter function, enabling smooth data exchange between two CAN networks using different CAN baud rates. In this application, the I-2533 module transmits data obtained from the EV charging piles to the PISO-CAN200U-T PCI Card, which the central controller is equipped with, through fiber optics and CAN interfaces.
The PISO-CAN200U-T PCI Card has two independent CAN ports, supporting programmable baud rates ranging from 10 kbps to 1 Mbps and compatible with the CAN specification 2.0 A and 2.0 B. It also provides the functions of arbitration, error detection, automatic error troubleshooting, and retransmission. The plug and play PCI Card supports a variety of drivers and third-party software. For example, SocketCAN, LabVIEW, DASYLab, RTX, etc., are supported, fulfilling the requirements of most CAN applications. In this case study, the PISO-CAN200U-T PCI Card receives data about the EV charging pile sent from the I-2533 module.
Benefits:
The I-2533 CAN to Multi-mode Fiber Bridge features a rotary switch design for management personnel to adjust the baud rate on the CAN bus easily.
Standard fiber-optic interface modules use two fiber optic cables to transmit and receive data, respectively. In contrast, I-2533 series I-2533CS-A and I-2533CS-B CAN to Single-mode Fiber Bridge use wavelength-division multiplexing (WDM) technology that enables bidirectional communications over a single fiber optic cable. The design keeps costs at a minimum. (Note: I-2533CS-A and I-2533CS-B must be used in pairs.)
The PISO-CAN200U-T PCI Card provides a 3 kV isolated DC/DC design and 2500 Vrms isolation enabled by the photocoupler on the CAN bus. The PCI card supports 5 V and 3.3 V PCI Bus, offering a jumper selection of 120 Ω termination resistors for each CAN port.
ICP DAS Intelligent CAN to Ethernet Gateway Ensures Fast and Reliable Data Transmission
ICP DAS also provides the CAN-to-Ethernet solution for CAN bus applications, sending data from the field to the control center quickly for remote monitoring. ICP DAS Intelligent I-7540DM CAN to Ethernet Gateway featuring both a CAN interface and an Ethernet interface (Modbus TCP/IP protocol), can be employed to transmit field data to the control center’s PC. This solution is suitable for communications over a relatively short distance between the field and the control center. The ICP DAS CAN-to-Ethernet solution has been successfully implemented for power monitoring of battery testing equipment in Taiwan and electric vehicle chargers in Spain.
Conclusion:
With the ICP DAS EV charging pile monitoring solution, customers can accurately monitor the status of electric vehicle (EV) charging equipment from remote locations. In the event of an emergency, maintenance personnel can be appointed to troubleshoot problems immediately, thereby saving time and costs incurred by performing periodic inspections.
The booming electric vehicle market will bring fast-growing demands for EV battery monitoring in the future. ICP DAS products provide high reliability, flexibility, and trustworthiness that answer customers’ requirements.
