Dc charging pile meter data processing and storage components
Main component
Concept:
The data processing and storage component of DC charging pile meter is the core component used to process and store electric energy data in the meter. It is responsible for receiving current, voltage, power and energy signals from the sensor, performing the necessary data processing, and storing the results for subsequent use. This data includes, but is not limited to, key information such as power consumption, charging time, cost calculation, etc., which is essential to ensure accurate billing and efficient operation of charging piles.
Function:
Accurate measurement: To ensure the accurate measurement of power consumption during the charging process, to provide a basis for billing.
Data logging: Record key parameters during charging, such as voltage, current, power, and energy, to facilitate fault diagnosis and performance monitoring.
Information security: Protects stored data from unauthorized access or tampering to ensure data security and integrity.
Remote monitoring: Supports remote data access, enabling operators to monitor the running status and energy consumption of charging piles in real time.
Working Principle:
Data acquisition: Through current and voltage sensors, the meter collects electrical parameters during the charging process in real time.
Data processing: The built-in microprocessor of the meter processes the collected data, including calculating power consumption, detecting anomalies, etc.
Data storage: The processed data is stored in the meter's memory for subsequent query and analysis.
Communication protocol: The meter uses the RS485 communication interface, such as DL/T 645-2007, DL/T698.45, Modbus and other protocols to exchange data with the external system.
Safety protection: The design of the meter meets the requirements of the S.A.F.E. safety Directive to ensure the safety of the data processing and storage process.
Real-time monitoring: The meter can monitor current, voltage, temperature, power and electricity in real time, and transmit these data to the host computer or cloud platform in an encrypted format.
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.
