2.1.2 Cell connector (CONN2) and current sense source (JB4)
2.1.3 Wiring for battery cell simulation

AVR454
CONN2 is used for connecting the battery cells in addition to power supply for the
charge/discharge current and cell voltage simulators. Refer to Figure 3-1 for
schematics.
Table 2-2. CONN2: Cell connections & Simulation
JB4 controls whether the Coulomb Counter ADC receives its input from R7 (the high-
accuracy 5mΩ current sense resistor), or from the Pack Current Simulator circuitry,
which includes VR6.
Table 2-3. JB4: Battery Pack Current Sense Source
Wiring CONN2 for battery simulation is shown in Figure 2-3 together with the required
jumper configuration for jumper blocks J1, JB3 and JB4. The correct wiring and
jumper settings are also shown on the board silkscreen. Note that the factory setting
for the simulator gives a voltage too low for the smart Battery to start properly.
This section only shows the required wiring and jumper settings. Further details on
battery voltage and charge/discharge current simulations are given in sections 2.4
and 2.5.
