Dc charging pile charging control unit CPU

Main component

Concept:

The CPU of the DC charging pile charging control unit (TCU) is the core processing component of the unit, responsible for handling all key tasks of the charging pile, including human-computer interaction, billing and metering, payment processing, data encryption and decryption, control of charging equipment, and communication with the vehicle networking platform.

Function:

Data processing: Processing of data from the charging pile sensor and user input.

Charge metering: The charge is calculated according to the charging time and power.

Payment processing: Processing payment transactions, including credit cards, mobile payments, etc.

Data security: Secure payment and user data through data encryption and decryption.

Device control: Control the start and stop of the charging device.

Network communication: Data exchange with the vehicle networking platform to achieve remote monitoring and upgrading.

Working Principle:

The CPU of the DC charging pile charging control unit usually adopts a high-performance ARM architecture processor, which has the following characteristics:

High performance processor: such as TI AM3354 Sitara processor, based on ARM Cortex-A8 architecture, the main frequency can reach 800MHz.

Memory and storage: Equipped with 512MB RAM and 1GB FLASH storage, support for external storage, such as TF card interface, can be expanded to 32GB.

Rich interfaces: Provides multi-channel communication interfaces, including RS485, CAN bus, Ethernet, 3G/4G module, etc., to meet the network transmission requirements in different environments.

Positioning function: Support GPS and Beidou dual-mode positioning, providing geographical positioning capabilities for charging piles.

Security module: Supports ESAM and PSAM module, complies with ISO7816 protocol, and is used for encryption chip requirements of billing unit.

Man-machine interaction: Support friendly man-machine interaction interface, such as Linux+QT interface display, 7-inch screen with LVDS interface, four-wire resistance touch.

Sum up

Through these high-performance hardware configurations and functions, the CPU of the DC charging pile charging control unit can ensure the stable operation and efficient management 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.
