3.3 Battery Management 

3.3.1 General function 

The  following  functions  should  be  performed  by  trained  and  qualified  professionals  with  specified 

software. 

1. 

Constant current boost charging 

The charge current can be set. 

2. 

Constant voltage boost charging 

Set the charge voltage according to battery type. 

For  Valve  Regulated  Lead  Acid  (VRLA)  batteries,  the  maximum  boost  charge  voltage  should  not         

exceed 2.4V/cell   

3. 

Float charge 

The float charge Voltage can be set as required by the type of battery. 

For Valve Regulated Lead Acid (VRLA), float charge voltage should be between 2.2V and 2.3V. 

4. 

Float charge temperature compensation (optional)   

The temperature compensation coefficients can be set depending on battery type. 

5. 

End of discharge (EOD) protection 

When  the  battery  voltage  falls  below  the  EOD,  the  battery  converter  will  automatically  be  off, 

disconnect the battery to avoid excessive battery discharge. EOD is adjustable from 1.6V to 1.75V per cell 

(VRLA) or 0.9 to 1.1 V per

 nickel-cadmium

 (Ni-Cd) cell. 

6. 

Battery low voltage alarm time 

Setting range, prior to the battery discharge termination 3 to 60 minutes, the default is 5 minutes. 

3.3.2 Advanced Functions (Battery Self-test Maintenance) 

Battery periodic discharge, and each time discharge 30% capacity. The actual load must exceed 30% 

of  the  UPS  nominal  capacity. If  the  load  is  below  30%,  it  does  not  perform  automatic  discharge 

maintenance. The  periodic  interval  can  be  set  from  every  30  to  360  days.  The  battery  self-test  can  be 
disabled. 

Conditions—batteries have been float charged for at least 5 hours, remain more than 30% of their rated 

capacity, the load within 20~100% of UPS rated capacity 

Be triggered—manually operate the command “Battery Maintenance Test” on LCD panel 

3.4 Battery Protection 

The  following  functions  should  be  performed  by  trained  and  qualified  professionals  with  specified 

software. 

1. 

Battery Low voltage alarm 

The battery under-voltage pre-warning occurs before the end of discharge. After this pre-warning, the 

battery  should  have  the  capacity  for  3  remaining  minutes  discharging  with  full  load.  The  time  is  user 

configured from 3 to 60 minutes. 

2. 

End of discharge (EOD) protection   

Before  the  battery  voltage  falls  below  the  EOD,  the  battery  converter  will  automatically  be  off, 

disconnect the battery to avoid excessive battery discharge. EOD is adjustable from 1.6V to 1.75V per cell 

(VRLA) or 0.9 to 1.1 V per

 nickel-cadmium

 (Ni-Cd) cell.   

3. 

Battery Circuit Breaker (BCB) Alarm (Optional) 

The BCB disconnecting occur this alarm. The batteries connect to UPS through the external battery 

circuit breaker (BCB). BCB is closed manually, the switch trips when there is battery over-temperature or 
electricity leakage by the UPS control circuit controlling.
