Injet finds that as electric vehicles (EVs) become increasingly prevalent, the demand for efficient and reliable charging infrastructure is paramount. DC charging stations play a crucial role in facilitating rapid charging for EVs, but the presence of a power controller within these stations can significantly enhance their functionality and maintenance procedures.
What is DC Charging controller?
A DC charging controller is the brain behind a DC fast charging station. It's responsible for managing the entire charging process, from communication with the vehicle to controlling the power flow.
Key Functions of a DC Charging Controller:
Communication: Acts as the interface between the charging station and the electric vehicle, exchanging data and commands.
Power Control: Regulates the amount of power delivered to the vehicle's battery, ensuring safe and efficient charging.
Safety Monitoring: Monitors various parameters such as voltage, current, and temperature to prevent faults and protect the vehicle and charging station.
Charging Process Management: Controls the different charging phases, including pre-charging, main charging, and post-charging.
Payment and Authorization: Handles payment transactions and user authentication.
What is the impact with or without a DC Charging Controller:
With Power Controller:
1. Programmable Power Controller (exclusive from INJET): This component acts as the brain of the charging station, allowing for precise control and regulation of power flow to the EV.
2. Integrated Smart HMI: Human-Machine Interface (HMI) provides a user-friendly interface for both operators and EV owners to monitor and control the charging process efficiently.
3. Charging Module: The core unit responsible for converting AC power from the grid to DC power suitable for charging EV batteries.
4. Cabinet: Housing for all the electrical components, providing protection and organization.
5. Cable & Plug: Essential for connecting the charging station to the EV for power transfer.
Without Power Controller:
1. DC Watt-hour Meter: Measures the amount of electrical energy consumed by the EV during charging.
2. Voltage Detection Transmitter: Monitors voltage levels to ensure safe charging operations.
3. Insulation Detector: Detects any insulation faults within the charging system to prevent electrical hazards.
4. Charging Pile Controller: Manages charging protocols and communication between the station and the EV.
5. Other Electrical Components: Including various power supplies, circuit breakers, relays, surge protectors, and wiring for electrical connections.

Impact of Maintenance with or without a DC Charging Controller
With Power Controller:
Maintenance of a DC charging station equipped with a power controller is streamlined and efficient, typically requiring less than 8 hours to resolve issues.
1. Fault Diagnosis: Automated background systems quickly identify faults, reducing diagnosis time to 2-4 hours.
2. Component Replacement: If necessary, the power controller can be directly replaced within 2-4 hours, minimizing downtime.
Without Power Controller:
Traditional maintenance procedures for DC charging stations lacking a power controller can be time-consuming, taking anywhere from 2 to 10 days to resolve issues.
1. On-site Inspection: Maintenance personnel must physically inspect the station, taking 1-2 days to locate the fault.
2. Part Replacement: Once the fault is identified, obtaining and replacing the necessary components can take 2-6 days, depending on availability.
3. Repair and Recovery: Finally, 1-2 days are needed to repair the station and return it to operational status.
