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.

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
