EV DC charging station
1. EV dc quick charger introduction
SETEC Power has experience in power electronic design and industrial product manufacturing, which allows for innovative product development and engineering. At presnet, SETEC Power specialize in manufacturing and developing on DC Fast Charging and DC connectors for CHAdeMO standard, the CCS (Combo) standard or GB/T (Chinese) standard electric vehicles .
The DC Quick Charger is a user-friendly and safe process to fast charge your vehicle. After user identification (if authentication is required), by simply choosing the charging standard compatible to your vehicle and coupling the charger’s output plug to the EV, you will have a fast secured and proven charging process. The battery charging status is displayed and the charging cycle finishes by itself or can be terminated by an user command.
The DC Fast Charger is highly recommended for service stations, EV service workshops and public EV Infrastructure.
•Using charging module, built-in module with CPU intelligent management, with manual / automatic dual control function;
•Using intelligent module, consisting of a distributed control system. A single module failure does not affect system operation;
•Charging module uses ZVZCS, three-phase PFC, three-level soft-switching technology, efficiency up to 95%;
•Charging module has a sleep function. According to the load current, the clients can automatically select the number of modules to make efficient operation;
•Charging module uses a unique full isolation dust structure, built-in cooling fan with intelligent speed control. It can automatically adjust the fan speed according to the load to extend the life of the fan;
•Acceptable remote tripping command to achieve emergency shutdown;
•Charging module with PFC,the power factor 0.99, and THD <5%.

2. EV charging module Introduction
SETEC Power is providing state-of-the-art electronic modules to be integrated in DC fast charging station. Each module is CHAdeMO, CCS and GB/T compliant and can be stacked in pile.
SETDC modules operate in master or BMS mode. Your public charging stations now communicate via CHAdeMO/CCS. Each stackable 10kW power module can be deployed in a variety of use cases depending on the power output requirement (e.g. 20kw for the home or garage, or 50kw for a public charging station).
Module with full resonance, double soft-switching principles of design, efficiency > 96%;
Module with full isolation design. Module control part is fully isolated with the input and output of the main circuit. When some external factors will produce high voltage of module input or output part, internal module control circuit will not damage;
PCB with epoxy coating should be dampproof and dustproof;
Multiple anti-reverse-current protection design to prevent the intrusion of various fault current phenomenon;
SCM module built by CAN \ RS485 port communication.Monitoring system can monitor the module and operating condition;
With LCD display, real-time display module output voltage, current, easy operation and monitoring;
Regulators, current limiting function. It can be charged the battery groups and carried the load with the set voltage and current. When the output current is greater than the current limit ,module automatically works on steady flow operation;when the output current is less than the current limit ,it works on voltage regulator condition;
Output voltage and current regulation. It can adjust the output voltage and the maximum current limit via background monitoring;
Work in parallel. The same model module can work in parallel and share current. If one module failed,it will not affect the whole system operation;
Hot-swap. You can either plug in any one module to make access to or remove it from the system without affecting the normal operation;
LCD shows module parameters, and Status Indicator;
Protection and alarm: input, short-circuit, over temperature, overvoltage, and alarm indication.

3. DC charger connector for electric vehicles
SETEC Power has designed two models of DC quick charger connector [SET-EVD-C1] which CHAdeMO conformity, [SET-EVD-G2] designed for China market, which use GB/T standard, [SET-EVD-S3] designed for Europe electric cars. SET-EVD-C1 connector is to be used directly in the CHAdeMO specification EV fast charger for electric vehicles (EV). Equipped with our proprietary function, the SET-EVD-C1 ensures a high level of safety required for quick chargers that transmit a considerably higher level of electric energy than general home appliances. This new EV quick charger connector provides not only a high level of safety
but also excellent operability, high durability and excellent design.
3.2 The feature of a DC quick charger connector for EV
1.Excellent Operability Charging is performed by only inserting a plug into a
vehicle-side inlet. After charging is completed, push a buttom and withdraw the plug.
2.User-friendly Design. This connector is designed to operate viscerally by having handle shape.
3.Safety Design. The connector has automated triple safety lock system which prevents the disconnection of connector from vehicle-side inlet accidentally during charging.
4.A Wide Range of Operation Temperature SET-EVD-C1 can be used under a wide range of
environmental temperature from -30°C to 50°C.
5.High Flexibility and Durability. Easy-bend and tough rubber is used for the cable.
