Use the following guidelines to set up
the equipment:
- Set power supply #1 for 40 VDC, 6
A current limit and then turn off the supply.
- Connect the output of power
supply #1 in series with a current meter to J1 (VIN and PGND).
- Connect a voltage meter across J1
(VIN) and J1 (PGND).
- Connect load #1 in series with a
current meter to J3 (VBAT and PGND).
- Connect a voltage meter across J5
(VBAT and PGND).
- Set 23.5 V at electronic load
input.
- Connect J5 to the EV2400. Connect
J5 to the I2C PORT 2 on the EV2400.
- Make sure the jumpers are
installed as indicated in IO and Jumper Descriptions.
- Unplug Jumper 13.
- Turn on the computer and power
supply #1. Open the bqStudio software.
- Select Charger and
click the Next button.
- Select
Charger_1_00_BQ25756.bqz on the Select a Target
Page.
- After selecting the
target device, click Field View and then click the Read
Register button.
- Set WATCHDOG and EN_CHG to
disabled.
- In 16 Bit Registers, set
ICHG_REG to 4000 mA and IPRECHG to 1000 mA.
- Set EN_CHG to enabled. Plug in
Jumper 13.
- Set power supply #1 to 40 V,
measure
V(J1(VAC)) = 40 V ±
0.5 V
I(J1(IAC)) = 1.2
A ± 0.5 A
V(J3(VBAT)) = 23.5 V ± 0.5 V I(J3(IBAT)) = 2 A ± 0.5

- Set power supply #1 for 23 V,
measure
V(J1(VAC)) = 23 V ±
0.5 V
I(J1(IAC)) = 2.1
A ± 0.5 A
V(J3(VBAT)) = 23.5 V ± 0.5 V I(J3(IBAT)) = 2 A ± 0.5

- Set power supply #1 for 10 V,
measure
V(J1(VAC)) = 10 V ±
0.5 V
I(J1(IAC)) = 5 A
± 0.5 A
V(J3(VBAT)) = 23.5 V ± 0.5 V I(J3(IBAT)) = 2 A ± 0.5
