Parameter Setup
4.4.2.22 BATTERY TYPE
(Table 4.3, Screen No. 22)
Parameter “BATTERY TYPE” is used to change the function of the Temperature Sensor Jack
on the EVO
TM
Inverter / Chargers (6, Fig 2.1 in the EVO
TM
Manual) to accept potential free relay
contact closure control signal from the Battery Management System (BMS) of Lithium Battery
for stopping charging / inverting. The Battery Charger Section is designed to operate with either
Lead Acid Battery or Lithium Battery. The default setting is
0=Lead Acid
where the Temperature
Sensor Jack will be used for battery temperature compensation.
When using Lithium Battery where its BMS has capability of generating contact closure con-
trol signal for stopping charging / inverting, programmable parameter “BATTERY TYPE” has
to be changed from Setting 0=Lead Acid (Default setting) to Setting 1=Lithium.
NOTE:
Parameter “CHARGING PROFILE” (Section 4.4.2.21)will be required to be programmed
to select the desired charging profile for the Lithium Battery from the following options:
•
0=3 Stage Adaptive (Default for Lead Acid Battery)
•
1=3 Stage Type 1
•
2=3 Stage Type 2
•
3=2 Stage Type 1
•
4=2 Stage Type 2
[For details, please refer to parameter “CHARGING PROFILE” explained under
Section 4.4.2.21 above]
Lead Acid Battery charging voltages are required to be compensated based on the tempera-
ture of the battery cells. Hence, Battery Temperature Sensor [Fig 2.5(a) in the EVO
TM
Manual] is
required to be connected to the RJ-45 Jack marked “Battery Temp. Sensor” (6, Fig 2.1 in the
EVO
TM
Manual). Please see details at Section 3.15 in the EVO
TM
Manual for Models EVO-1212F /
1212F-HW / 1224F / 1224F-HW.
Charging voltages of Lithium Battery are not affected by temperature and hence, Battery
Temperature Sensor is not required to be used.
Pins 4 and 5 of the RJ-45 Jack marked “Battery Temp. Sensor” (6, Fig 2.1) are required to be
connected to the Normally Open Contacts of relay in the Battery Management System (BMS)
of the Lithium Battery for “Stop Charging or “Stop Inverting” signals (For details, refer to
Section 3.16 of the EVO
TM
Manual for Models EVO-1212F / 1212F-HW / 1224F / 1224F-HW).
The BMS will close the Relay contacts as follows:
• To “Stop Charging”: Due to (i) overvoltage of individual cell / overall battery pack, or
(ii) over temperature of individual cell or overall battery pack
• To “Stop Inverting”: Due to deep discharge to the level of Low Battery Cut Off Voltage
When the Relay contacts in the BMS close, Pins 4 and 5 of RJ-45 Jack will be shorted. The
following actions will be activated:
•
EVO
TM
in Charging Mode:
The charging will stop (charging current will be reduced to
0A). The 2
nd
Line of the Charging Mode Screens shown in the Menu Map for Charg-
ing Mode Screens [Fig 3.1(a) and 3.3(b)] will show “Charger Off by BMS” as shown in
example below for Screen No. 1
