The LithiumIon sub menu can be viewed if LithiumIon is selected as the Batt

Type. This menu allows you to select an external BMS or adjust charging

specifications for lithium ion batteries that fall outside the default settings for the

battery types the Conext XW+ offers.

Table 3-4 describes the items on the Custom Battery Settings menu.

Table 3-4 Custom Battery Settings Menu

Item Description

Custom Settings

This sub menu contains the following settings: Eqlz Support, Eqlz Voltage,

Bulk Voltage, Absorb Voltage, Float Voltage, and Batt Temp Comp.

Eqlz Support Enables or disables the ability to enter an equalization cycle. Refer to the

battery manufacturer’s specifications to determine whether equalization is

recommended.

Eqlz Voltage

Selects the equalization voltage. Consult your battery manufacturer for

equalization voltage setting.

Bulk Voltage Sets the bulk voltage for a custom battery type.

Absorb Voltage Sets the absorption voltage for a custom battery type.

Float Voltage Sets the float voltage for a custom battery type.

Batt Temp Comp Battery temperature compensation for a custom battery type. This setting is the

reference that the BTS uses to adjust the charging voltage when the

temperature is above or below 25 °C (77 °F).

The following voltage thresholds are not temperature compensated:

• Grid Support entry voltage

• Grid Support exit voltage

• Low Battery Cut-Out trigger voltage

• Low Battery Cut-Out condition clear voltage

The following battery voltage set points are temperature compensated:

• Float exit voltage

• Bulk exit voltage

• Float and Gassing voltages used in Constant Voltage exit criteria

• Recharge Volts

• Charge Control target voltage

LithiumIon

This sub menu contains the following settings: Control and the voltage and

current settings in the shaded rows on the next page.

Control Configures the Battery Management System (BMS) for Lithium Ion. Contains

three options namely: EXT_BMS, 2StageNoFloat, and 3Stage.

EXT_BMS Used for an external BMS. When selected, all subsequent voltage and current

settings disappear (shaded rows). Battery charging is controlled by the BMS.

2StageNoFloat Used for 2-Stage Lithium Ion charging. Allows for Bulk Voltage, Max Bulk

Current, DisChglmax, and DisChglmax Timer settings (in shaded rows).
