EV charging module Introduction:
SET-QM series Electric Vehicle Charging Module is multifunction, intelligent charging high-frequency switch module, designed for charging stations, power plants, etc..
Non- board charging system for electric vehicles consists of electric vehicle charging module and monitor(SET1410), used for EV charging/battery swap station.
The main features of the module
1. Module with full resonance, double soft-switching principles of design, efficiency ≥ 96%;
2. 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;
3. PCB with epoxy coating should be damp proof and dustproof;
4. Multiple anti-reverse-current protection design to prevent the intrusion of various fault current phenomenon;
5. Input uses three-phase four-wire , three-phase equilibrium;
6. SCM module built by CAN \ RS485 port communication. Monitoring system can monitor the module and operating condition;
7. With LCD display, real-time display module output voltage, current, easy operation and monitoring;
8. 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;
9. Output voltage and current regulation. It can adjust the output voltage and the maximum current limit via background monitoring;
10. 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;
11. 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;
12. LCD shows module parameters, and Status Indicator;
13. Protection and alarm: input, short-circuit, over temperature, over voltage, and alarm indication.
Efficiency
We know efficiency is an important parameter in energy saving . The power is more large, and then if the efficiency will increase each 1%, most significant here is saving energy and economic returns. There formula: power consumption = charger output power / charger efficiency.
Figure shows, assuming the charger module total power 200kw, charging 10h per day, and load 50% , if the difference between the charging efficiency of 3%, pls see as below:
93% efficiency: power consumption = 200Kw*10h/93%=2150 kw.h
96% efficiency: power consumption = 200Kw*10h/96%=2083 kw.h
So, it saved 67 kw.h
Assumed electricity bill is 1 yuan / kWh , you can get a year saving and economic returns:
Saving bills=67(kw.h)*365(Day)*1(RMB)=RMB24455(US$3989)
SET1410 Monitor introduction:
SET1410 monitoring module is designed for DC charger with protocol CAN2.0.The number of modules can be set from 1 to 13.SET1410 module uses 6.4-inch LCD display with a keyboard and a touch screen.
