DC charging pile communication interface chip signal converter
Main component
Concept:
The signal converter of the DC charging pile communication interface chip is a key component, which is responsible for converting communication signals of different standards between the charging pile and the electric vehicle. This converter ensures that the charging standards of different countries and regions are compatible with each other, allowing electric vehicles to use a variety of charging facilities worldwide.
Function:
1. Compatibility: Support a variety of communication protocols, such as ISO15118, DIN70121, SAE, CHAdeMO, etc., to ensure the communication compatibility between charging piles of different standards and electric vehicles.
2. Communication conversion: Realize the conversion between national standard charging pile CAN communication signal and international standards such as ISO15118(EIM), DIN70121 communication protocol standard PLC signal.
3. Two-way communication: Support the application of electric vehicles to the grid two-way communication (V2G protocol) to achieve smarter energy management.
4. Charging mode switch: It can flexibly switch between fast charging and slow charging mode to adapt to different charging needs.
Working Principle:
1. Signal reception: The signal converter first receives the signal from the pile controller or EVSE board.
2. Signal analysis: The received signal is analyzed and converted into the corresponding standard.
3. Signal conversion: the received signal is converted into a standard that can be read by the receiver.
4. Signal transmission: the converted signal is transmitted to the electric vehicle charging pile control board or EVSE board.
5. Isolated communication: Isolation chips such as CA-IS2092W and CA-IS3642HVW are used to achieve isolated signal transmission and improve the safety and reliability of the system.
6. Integrated design: The transceiver chip, isolation chip and DC/DC isolation power supply are integrated in one module to simplify design and save space.
Sum up
Through the above principles, the signal converter of the DC charging pile communication interface chip ensures the smooth communication between the charging pile and the electric vehicle, supports the compatibility of different charging standards, and improves the versatility and practicability of the charging pile.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
