Dc charging pile communication interface chip interface standard support
The interface standard support of DC charging pile communication interface chip mainly involves the following aspects:
Main component
Support for international standards
ISO 15118: This is a charging pile communication protocol developed by an international standardization organization, covering the basic communication needs between vehicles and charging piles, and detailing the specific implementation and application scenarios of the protocol. The ISO 15118 protocol covers not only traditional conducted charging, but also V2G (returning electricity to the grid) and wireless charging.
IEC 61851 & IEC 62196: IEC 61851 defines conductive charging systems for electric vehicles, covering both AC and DC charging, ensuring safety and interoperability. IEC 62196 defines physical connectors for electric vehicle charging, including the Type 2 interface used in Europe.
Regional standard support
CHAdeMO: This is a DC fast charging standard jointly developed by Japanese automakers and electric power companies to support high-power DC charging between electric vehicles and charging devices.
CCS (Joint Charging System) : This is a standard that allows the use of a standard global vehicle AC and DC charging interface, integrating AC and DC into a single intake port.
Communication protocol support
Dc charging pile communication interface chip needs to support a variety of communication protocols, such as:
CAN bus protocol: GB/T 20234.3-2015 specifies the communication between DC charging piles and electric vehicles through the CAN protocol.
DIN SPEC 70121: This is a European-specific charging interface standard that exchanges the necessary charging parameters with vehicles through a CCS charging interface that complies with IEC 61851-23.
Sum up
In summary, the DC charging pile communication interface chip needs to support a variety of domestic and foreign standards and communication protocols to ensure the compatibility, security and interoperability 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.
