Definitions


Field	Contents	SI Unit Example
`MID`	Material identification number. No default (Integer > 0)
`RCNUM`	Indicates the number of resistor-capacitor pairs in the battery cell elements. No default (Integer: 1, 2, 3, 4 or 5)
`TCFLAG`	Indicates whether the material properties are defined by tables or in constant. = 1 `Ri` and `Ci` are constant values. = 2 `Ri` and `Ci` are from tables. No default (Integer 1 or 2)
`DISCHA`	Label to indicate `VOC`, `Ri` and `Ci` are for discharging status.
`CHARGE`	Label to indicate `VOC`, `R0`, `Ri` and `Ci` are for charging status.
`INITVP`	Label to indicate the following fields are for initial polarized voltage.
`VOC`	Open circuit voltage of the battery cell. Real > 0.0 when `TCFLAG` = 1. Integer > 0 when `TCFLAG` = 2. No default
`R0`	Internal resistance of the battery cell. Real > 0.0 when `TCFLAG` = 1. Integer > 0 when `TCFLAG` = 2. No default
`Ri`	Resistance of the i^th RC pair in the battery cell. Real > 0.0 when `TCFLAG` = 1. Integer > 0 when `TCFLAG` = 2. No default
`Ci`	Capacitance of the i^th RC pair in the battery cell. Real > 0.0 when `TCFLAG` = 1. Integer > 0 when `TCFLAG` = 2. No default
`INITVP`	Initial polarized voltage of the i^th RC pair in the battery cell. Real > 0.0 when `TCFLAG` = 1. Integer > 0 when `TCFLAG` = 2. No default

Comments

The material identification number must be unique for all other material definition entries.
The circuit of a BCELL element is shown as below.

When TCFLAG = 2, all material properties are taken from tables. The tables define the dependency of temperature, state of charge on each field by TABLEMD.
