5.12.1 Charging Profiles for Lithium Batteries
There are 3 Charging Profiles available for charging Lithium Batteries: (i) 3 Stage Type 1, (ii) 2
Stage Type 1 and (iii) 2 Stage Type 2. Please refer to Table 5.2 for details
Charging voltages of Lithium Battery are not affected by temperature and hence, Battery
Temperature Sensor [Fig 2.5(a)] is not required to be used.
5.12.2 Stop Charging and Stop Inverting Protections When Charging
Lithium Batteries
As mentioned under CAUTION above, the Battery Management System (BMS) of the Lithium
Battery may need to provide the following potential free, contact closure control signals to
the Inverter Charger for battery protection:
• “Stop Charging” control signal (potential free, contact closure) to the Battery Charger
Section to prevent (i) over voltage of individual cells / over voltage of the battery pack and
(ii) over temperature of individual cells / over temperature of the battery pack
• “Stop Inverting” control signal (potential free, contact closure) to the Inverter Section so
that the battery stops discharging to prevent deep discharge of the battery
Pins 4 and 5 of the RJ-45 Jack (6, Fig 2.1) can be programmed to accept the above potential-
free relay contact closure signal from the BMS. In default condition, Pins 4 and 5 of the RJ-45
Jack (6, Fig 2.1) are programmed for temperature compensation for Lead Acid Batteries
through battery temperature information received from Battery Charger Temperature Sensor
EVO-BCTS. Parameter “BATTERY TYPE” is used to select one of the above 2 functions of the
RJ-45 Jack (6, Fig 2.1) as follows:
Programming Parameter: “
BATTERY TYPE
” for selecting function of RJ-45 Jack marked
“Battery Temp. Sensor” (6, Fig 2.1)
Setting
0=Lead Acid
(Default)
Temperature compensation through battery temperature
information from the Battery Charger Temperature sensor
EVO-BCTS
Setting
1=Lithium
Connect Pins 4 and 5 to potential free contacts of the BMS
of the Lithium Battery
If the BMS of the Lithium Battery being used has the ability to provide potential-
free relay contact closure signal for stopping of charging / inverting functions as
described above, parameter “BATTERY TYPE” should be programmed for setting
1=Lithium as explained above.
For details of above programming, please refer to Section 4.2.2.22 of the EVO-RC
PLUS Remote Control Manual.
