Product Description

Ensures safe and efficient charging power Intelligent DC EV charger control unit

The CCU (EV charger control unit) is the core component of the EV charging system and is responsible for managing the entire charging process. It acts as the "brain" of the EV charging system, receiving signals from vehicle controllers, charging piles and other components, and controlling the charging process according to these signals to ensure safe and efficient charging. Signal acquisition: The EV charger control unit collects signals sent by the vehicle controller, battery management system, charging pile and other components, such as battery SOC, charging status, charging pile type, etc., through CAN bus and other communication methods. The CCU can communicate with the display (OCU), power control board (PCU), SECC, CHAdeMO conversion board, power module, and energy meter. The main functions are as follows: 1) Communicate with OCU and enable remote debugging; 2) Communicate with the PCU power control board to achieve remote debugging; 3) Detect the connection status of the charging gun; 4) Collect positive and negative

CCU integral part: The control unit of CCU DC charging pile is usually divided into the following parts: Rectifier: Responsible for converting the AC input to the DC output Inverter: Converts DC to AC for feedback into the grid when needed Controller: It is used to monitor and manage the charging process, including adjusting and controlling the input power, output power and charging time, etc., and is responsible for controlling the operation of the entire CCU. Memory: Used to store control programs and data. Communication interface: Used to communicate with other components. Power module: Used to control the charging current

How CCU works:
The CCU DC charging pile control unit is a kind of social security for electric vehicle charging, and its working principle is based on the combination of traditional charging technology and modern control technology. It converts AC power to DC power and properly supplies electric vehicles for a fast, safe and university charging process.
1. Signal acquisition: The CCU collects signals sent by the vehicle controller, battery management system, charging pile and other components, such as battery SOC, charging status, charging pile type, etc., through CAN bus and other communication methods.
2. Data processing: The CCU processes and analyzes the collected data to determine the best charging strategy.
3. Control output: The CCU sends control instructions to the charging pile according to the charging strategy to control the charging current, voltage and other parameters.
4. Status monitoring: The CCU monitors the charging process in real time and adjusts the charging strategy according to the charging status.

Technical condition of the CCU
High reliability: The working reliability of CCU directly affects the safety and efficiency of charging, so CCU is required to have high reliability.
High precision: CCUs need to precisely control the charging current and voltage to protect the battery and improve charging efficiency.
Quick response: CCU needs to respond quickly to various changes in the charging process to ensure the safety and efficiency of charging.
Compatibility: The CCU needs to be compatible with a variety of charging standards and charging station types.

Workflow of the CCU 1. Vehicle connection: After the electric vehicle is connected to the charging pile, the CCU receives the charging request. 2. Identity authentication: The CCU authenticates with the charging pile to ensure the safety of charging. 3. Charging parameter setting: CCU sets charging parameters according to the SOC of the vehicle battery, the power of the charging pile and other information. 4. Charging start: The CCU sends a command to the charging pile to start charging. 5. Charging process monitoring: CCU monitors charging current, voltage, temperature and other parameters in real time, and adjusts the charging strategy according to these parameters. 6. Charging Completed: When the battery is fully charged or charging is completed, the CCU sends a command to the charging pile to stop charging CCU's communication protocol CCUs typically use the following communication protocols to communicate with other components: CAN bus: CAN bus is an efficient and reliable serial communication protocol, which is widely used in automotive electronic systems. The CCU can communicate with the vehicle controller, battery management system, etc. via the CAN bus. Charging protocols: CCUs need to support various charging protocols, such as CHAdeMO, GB/T, CCS, etc. Communication interfaces: CCUs usually have a variety of communication interfaces, such as Ethernet, Wi-Fi, etc., for communication with external systems. Reference data for the CCU Processing power: Capable of handling multiple charging protocols and complex charging algorithms. Communication rate: Meet the communication requirements of CAN bus, charging protocol and so on. Operating temperature range: -40°C~85°C

The future development trend of CCUs
Intelligent: Through the introduction of artificial intelligence technology, the intelligent control of the charging process is realized.
Networking: Connect the CCU to the Internet for remote monitoring and management.
Integration: Integrate the CCU with other control units to improve the integration of the system.
Tips: Due to the continuous development of EV charging standards and technologies, the specific technical parameters and application methods of CCU may change, it is recommended that you refer to the latest technical information in practical applications. Product Description
