Set this parameter based on the number of connected battery strings. For example, if four battery fuses or circuit breakers are reserved in the power system but actually only battery strings 1 to 3 are connected, set Battery1 Connected, Battery2 Connected, Battery3 Connected to Yes, and set Battery4 Connected to No. Rated Capacity

Total rated capacity of batteries controlled by each battery fuse or circuit breaker.

1000 Ah

5-12000

NOTE If one fuse or circuit breaker is connected to one battery string and the battery strings connected have different capacities, set Rated Capacity to the minimum battery string capacity. For example, if fuse 1 is connected to a 1000 Ah battery string and fuse 2 connected to a 1200 Ah battery string, set Rated Capacity to 1000 Ah. If one fuse or circuit breaker is connected to multiple battery strings, calculate the rated capacity based on the minimum battery string capacity. For example, if two battery strings (one 1000 Ah, the other 1500 Ah) are connected to one fuse, set Rated Capacity to 2000 Ah (2 x 1000 Ah).

Configuration Example The configuration example shown in Figure 5-3 is as follows: 

The power system is configured with two DC cabinets.



DC cabinet 1 contains two fuses, each of which is connected to two battery strings.



DC cabinet 2 contains two fuses, one of which is connected to two battery strings.

In this example, battery parameters are configured as follows: 

Rated battery capacity = 2 x Capacity of each battery string If the capacity of each battery string is 1500 Ah, set Rated Capacity to 3000 Ah. If the battery strings have different capacities, use the smallest value to calculate the rated capacity. For example, if the capacity of battery string 1 is 1000 Ah and the capacity of battery string 2 is 1500 Ah, set this value to 2000 Ah.

7.1.5 Intelligent Rectifier Hibernation Principles The rectifier efficiency increases in proportion to the load power. If the total load power is low, certain rectifiers hibernate to increase the load power of working rectifiers and raise the rectifier efficiency. This facilitates energy conversation. The rectifier service life is prolonged because rectifier runtime is reduced. Figure 7-1 shows a rectifier efficiency curve. Figure 7-1 Rectifier efficiency curve (R48100G1 used as an example)

The SMU controls rectifiers to start and hibernate based on the loading capacity of the power system. If the load power decreases, the SMU instructs certain rectifiers to hibernate. If the load power increases, the SMU starts rectifiers to meet load power requirements. To ensure that all rectifiers operate at the same degree of deterioration, the SMU instructs different rectifiers to hibernate each time based on their real-time efficiency and runtime. See Figure 7-2.

7.2 Power Segment Management When the system output power is insufficient due to an AC input exception or a rectifier fault, batteries feed power to the loads. To prolong the operating duration of primary loads and avoid reducing the battery lifespan due to overdischarge, the SMU controls the battery low voltage disconnection (BLVD) and load low voltage disconnection (LLVD) routes to disconnect the power supply to loads based on power disconnection parameters. After the AC input or rectifier recovers, the SMU controls the BLVD and LLVD routes to reconnect the power supply to loads. According to the power distribution design, the SMU supports power segmentation. You can set disconnection parameters based on the load type to disconnect secondary loads first and then primary loads. This effectively extends the power backup time for primary loads. BLVD management applies only to a power system configured with battery contactors.



After the BLVD route is disconnected, the power system does not feed power to loads.



You can disable BLVD. After BLVD is disabled, batteries may be damaged by overdischarge if a lengthy mains outage occurs.



To ensure that the entire system runs securely, if any of the Communication Failure (including Cabinet MUS02B Communication Failure), Address Conflict, and Unknown Cab Type alarms occurs, the power system runs with the BLVD and LLVD contactors closed. The power segment management logic is implemented only if none of the preceding alarms occurs.

7.3 Lead-Acid Battery Management 7.3.1 Charging Management Principles If the AC input to the power system is normal and meets load requirements, rectifiers supply DC power to loads and charge batteries. If the AC input is abnormal or rectifiers are overloaded or faulty, the batteries will supply power to loads. After the fault is rectified, rectifiers continue to supply DC power to loads and charge the batteries. The SMU enables batteries to switch between float charging and equalized charging by adjusting the system output voltage. 

Float charging: charges batteries with an appropriate voltage to compensate for self-discharge after they are fully charged.



Equalized charging: fully and rapidly charges batteries with an increased output voltage. During equalized charging, the SMU limits the rectifier output current to prevent battery damage caused by an excessive charge current.

The scheduled charging time arrives. The SMU allows charging batteries periodically in equalized mode. After each equalized charging is complete, the SMU determines the start time of the next charge.

Manual equalized charging

You start equalized charging manually. For details, see 5.2.15 Switching Between Equalized Charging and Float Charging.

Issue 05 (2016-12-20)

Manual termination: You terminate equalized charging manually. For details, see 5.2.15 Switching Between Equalized Charging and Float Charging. Abnormal termination: The SMU stops equalized charging when detecting exceptions about the AC input, rectifiers, or batteries, such as high battery temperatures. NOTE If flooded batteries are used, manually start forced equalized charging. Forced equalized charging is terminated if: 

The period specified by Equalized Charge Maximum Duration expires.



You terminate charging manually.

7.3.2 Temperature Compensation Principles To reduce the effect of ambient temperature on batteries, prolong the battery lifespan, and maintain a reliable charge current, the SMU adjusts the system output voltage based on the optimal operating temperature, present battery temperature, and temperature compensation coefficient.

7 Feature Description

The SMU decreases the system output voltage when the temperature rises and increases it when the temperature drops. The adjustment range for battery temperature compensation is 51.5 V to 55.5 V. Temperature compensation is effective only when batteries are in float charging state. The SMU does not perform temperature compensation if the battery temperature sensor is disconnected or faulty. Figure 7-6 shows the temperature compensation control logic. Figure 7-6 Temperature compensation control logic

7.3.3 High or Low Temperature Alarms and Protection Principles As the battery temperature rises, the SMU generates an alarm and takes a preset action to protect the batteries. This mechanism prevents battery lifespan reduction or battery damage. Alarms and protective measures are as follows: 1.

When the battery temperature exceeds High Temperature Alarm Threshold, the SMU generates a high temperature alarm.

2.

When the battery temperature exceeds Very High Temperature Alarm Threshold, the SMU implements the selected protection measure. You can select any of the following protection measures: −

Lower the battery charge voltage

−

7.3.6 Balance Monitoring The SMU monitors the battery balance in real time as follows: 

Monitors the middle point voltage balance.



Monitors the current balance.



Monitors the balance of each battery (a battery voltage detector is required).

(Optional) Monitoring the Middle Point Voltage Balance The SMU monitors the voltage balance for all batteries in each battery string in real time by using a signal cable for monitoring battery middle point voltages. If the battery voltages are unbalanced, the SMU generates a Battery n Voltage Imbalance alarm. The number of battery strings to be monitored depends on the power system type. The SMU monitors the voltage balance for a maximum of six battery strings. Figure 7-7 shows the logic diagram for middle point voltage balance monitoring Figure 7-7 Logic diagram for middle point voltage balance monitoring

Monitoring the Current Balance When batteries are discharging, the SMU generates a Curr Imbalance Between Batts alarm if detecting that the maximum current deviation between battery strings exceeds 0.05C10. The alarm must be manually cleared.
