SANDI SERIES charging module is for electric vehicle charging station. With single-phase non neutral conductor AC input, it has the advantages of high efficiency, high power density and low harmonic. Functional details 1. Hot plug Plug technology is applied to the charging module to provide convenience for installation and maintenance. The access of the charging module to the system shall not disturb the output voltage of the system. 2. Advanced current sharing technology Under constant voltage working mode, the charging modules can share current automatically within 10S, with degree of unbalance less than �±0.5A. 3. Control of input limited power Refer to Fig. 1-10 for the relation between the output power and input voltage of the charging module. When the input voltage is within 360 Vac ~ 450 Vac (return difference is less than 5V), the module can output the maximum power of 20 KW; when the input voltage is within 260 Vac ~ 320 Vac, the module can still work normally under limited power mode. 4. Control of output constant power When there is a rated input voltage, the output power of the module is 20 KW. Refer to Fig. 11 for the relation between the output voltage and the output current of the module. The SD75050 module uses two operating modes with output voltage ranges of 50 to 750V. The module only selects the operating mode based on the value of the received demand voltage, and does not select the operating mode based on the actual output voltage. 5. Temperature limited power 6. Regulation of output current limiting point 8. Regulation of output voltage The output voltage of the module can be regulated constantly through the external monitoring module, with regulation range of 50Vdc ~ 750Vdc and minimum regulation step of 0.1 Vdc. 9. Fan control The built-in processor of the module can regulate the speed of the fan according to the internal temperature and output current of the module. 10. Protection of input overvoltage/ voltage shortage 11. Output overvoltage protection The overvoltage protection point is 260Vdc ~770Vdc (�±10 Vdc). Default is 778Vdc.The module can be started after manual intervention upon overvoltage protection. 12. Over-temperature protection The environmental over-temperature protection point is 80�°C. When the DC panel has a temperature over 100�°C, the module will stop working; when the DC panel has a temperature below 90�°C, the module will automatically work again. 13. Protection of internal bus fault When the internal bus voltage of the module is beyond the overvoltage/ voltage shortage protection point, the module will be powered off automatically. At this time, there is no output from the module and the fault indicator light is on. 14. Short circuit protection In case of short circuit of the module, it will be subjected to protective shutdown and the red indicator light of the panel is on, and this condition will be transmitted to the monitor of the "module fault".
Basic Parameters Dimensions: 201 x 99 x 35 mm Weight: 333g Adapter Input: AC 100 ~ 240 V Output: DC 24V 2.65A Display mode Segment LCD with white backlight + LED in red and green Function Introduction Charge Active, pre-charge, constant current and constant voltages are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don't happen to every batteries. For charging mode and current, please refer to the paragraphs of charging mode and charging current on page 2 & 3. Tester will stop charging if one of the conditions below was met. 1) Remaining capacity 99% & current intensity = 0 2) Remaining capacity = full charge capacity 3) Current intensity reduce to end charge current when constant voltage charge 4) Remaining capacity reach up the set value Discharge Constant current discharge for double loads Inner load: 0 ~ 1000mA, adjustable continuously via Battery Manager External load: 0mA, 500mA, 1000mA, 1500mA, 2000mA, five gears with dip switches offered Tester will stop discharging if one of the conditions below is met. 1) Remaining capacity set value 2) Voltage set value 3) Current intensity reduce to zero Remarks: Many batteries can not measure exact current intensity, which cause an else current value appears after you set a value. However, the actual discharging current is the same with your set value. Test Testing time is 12 seconds and the purpose is to check both the charging and discharging performances. After finishing test, LED flickers with green color and LCD reports the test result. Normal: Test OK Shown on LCD Abnormal: Test NG Shown on LCD Possible causes and solutions for the abnormal: 1) Cause: battery voltage is too low to discharge Solution: try to charge the battery to raise voltage 2) Cause: remaining capacity is too full to charge any more Solution: try to discharge the battery to reduce the remaining capacity 3) Bad contact of battery connecting wires 4) Damaged battery 5) Tester trouble Capacity Correction The battery capacity value in the battery management chip will different from the actual capacity after a battery goes through many recycling cycles. It will affect the use of the battery when the difference reaches a certain degree. Capacity correction is to deep discharge a battery and then fully charge, which will correct the capacity value in the battery management chip. Remarks: Discharging current can be set via Battery Manager. Deep discharge will cause a battery losing communication with tester, so battery dropping phenomenon may happen in the discharging process if the end capacity and voltage are set too low. In such a case, active charge will make the battery work again. 50% Capacity CD50%: charge firstly, and then discharge to 50% capacity DC50%: discharge firstly, and then charge to 50% capacity Online Functions Tester can be connected with master machine via a USB port. Users can monitor, control and set parameters via Battery Manager software in the master machine. Monitoring Battery information can be monitored via three windows. 1. Home screen Battery bar and brief information can be read on home screen. 2. Battery detail information window Show smart battery data in real time and the data can be saved and printed in image format. 3. Battery graph window Voltage, current and capacity are traced in curves. Control Battery Manager can control slave machine completely. Right-click menu on the battery bar includes the related commands. Attention All the functions of charge, discharge, capacity correction and 50% capacity are comply with the charging discharging conditions, which are showed on function introduction paragraph in page 4 & 5, so parameters should be set reasonably. Especially, deep discharge will cause a battery losing communication with tester. Others 1. Active cooling 2. Active batteries of zero voltage When a battery is deep discharged, the discharge protection circuit will start up and the voltage in the battery connector will become zero voltage. In this case, an appropriate voltage should be supplied to active the battery. 3. Battery identification Battery information can be read from battery management chip after establishing communication. 4. Intelligent protection Against over-current, over-voltage, over-charge, over-heat and short circuit. 5. Fan Discharging mode: fan startup Other modes: fan startup when temperature above 48 Fan stop working when temperature below 40 6. Trouble alarm LED flickers in red color and current command stops when one of the conditions below happen. 1). There is not current for around 50 seconds when charge. 2). There is not current for around 25 seconds when discharge. 3). Charging time is above 8.8 hours. 4). Discharging time is above 9.9 hours. 5).
