4.4.2.22 BATTERY TYPE (Table 4.3, Parameter Setup Screen No. 22)
4.4.2.22.1 General Information
Parameter "BATTERY TYPE" is used to change the functionality of RJ-45 Jack marked "Battery Temp. Sensor" on the
front panel of EVO (6, Fig 2.1 in the Owner's Manuals for EVO
TM
options are available:
a) Option 1 - "0=Lead Acid" (Default setting): With this default setting, the RJ-45 Jack will be set to accept input
from the Battery Temperature Sensor EVO-BCTS (Fig 2.5(a) in the Owner's Manuals for EVO
when Lead Acid or Nickel-Zinc (Ni-Zn) batteries are being used. Input from the Battery Temperature Sensor will be used
to compensate the charging voltages based on the temperature of the Lead Acid or Nickel-Zinc (Ni-Zn) batteries. Please
refer to Section 5.5 of the Owner's Manuals for EVO
for Lead Acid and Nickel-Zinc (Ni-Zn) batteries
b) Option 2 - "1=Lithium Ion": With this setting, the RJ-45 Jack will be programmed to receive and process protection
control signals "Stop Charging" or "Stop Inverting" from Lithium Battery Management System (BMS). Application of
this setting is explained at Section 4.4.2.22.2 below
4.4.2.22.2 Stop Charging" and "Stop Inverting" Control by Lithium Ion Battery Management System (BMS)
For protection against over-voltage / over-temperature / over-discharge, Lithium Ion Battery Management Systems
(BMS) will normally have capability of providing potential free relay contact closure signal that could be fed to Inverter
Charger to stop charging or stop inverting. For this, the BMS will normally use miniature, Normally Open (1-Form-A),
Open Drain Opto-Isolated DC Solid-State Relay (SSR). The Solid-State Relay output terminals in the BMS are normally
marked "+" (Drain of Mosfet Switch) and "-" (Source of Mosfet Switch). Example of this type of relay is IXYS Part No.
"CPC1002N" (60V, 700mA rating).
The following 2 types of signals are normally used by the BMS for on/off control of charging and inverting operation
of the Inverter-Charger:
• "Stop Charging" Signal: In case of (i) over voltage of individual cell / overall battery pack, or (ii) over
temperature of individual cell or overall battery pack, the signal will be "enabled" and Solid-State Relay (SSR)
contacts will close [Drain (+) and Source (-) Terminals will be shorted].
• "Stop Inverting" Signal: In case of deep discharge of the battery to the level of Low Battery Cut Off Voltage,
the signal will be "enabled" and the Solid-State Relay (SSR) contacts will close (Drain (+) and Source (-) Terminals
will be shorted).
If the above two protection functions of the BMS i.e. "Stop Charging" and "Stop Inverting" are to be used for on/ off
control of charging and inverting operations of EVO
undertaken:
a) Programming parameter "BATTERY TYPE" must be changed from Option 1 - "0=Lead Acid" (Default
setting) to Option 2 - "1=Lithium" (see Section 4.4.2.21 above). With this setting, the function of front
panel RJ-45 Jack marked "Battery Temp. Sensor: (6, Fig 2.1 in the Owner's Manuals for EVO
Inverter/Chargers) will change from accepting and processing battery temperature signal from the Battery
Temperature Sensor EVO-BCTS to accepting and processing potential free relay contact closure signal from
the Solid-State Relay (SSR) from the BMS to stop charging /inverting.
