2.4 Equipment
TI recommends two ways to test the EVM. The first and preferred way to test the EVM is to use a four-quadrant
power supply. The second is to use a electronic load in constant voltage mode. Testing with a constant voltage
load is covered in
Section
power supply.
1. Power Supplies:
A power supply capable of supplying 40 V at 8 A is required. This part can handle larger voltage and current,
however, larger power levels are not necessary for this procedure.
2. Load 1:
A Kepco load: BOP36-6M, DC 0 to ±36 V, 0 to ±6 A (or higher), or equivalent. When testing without a real
battery, connect 2000 uF of capacitance across the input.
3. Meters:
Six Fluke 75 multimeters, (equivalent or better) or: Three equivalent voltage meters and three equivalent
current meters.
4. Computer:
A computer with at least one USB port and a USB cable.
5. EV2400 Communication Kit
6. Software:
Download and properly install bqStudio.
2.4.1 Equipment Set Up
Use the following guidelines to set up the equipment:
1. Set power supply 1 for 23 V DC, 8 A current limit and then turn off the supply.
2. Connect the output of power supply 1 in series with a current meter to J1 (VIN and PGND).
3. Connect a voltage meter across J1 (VIN) and J1 (PGND).
4. Connect load 1 in series with a current meter to J3 (VBAT and PGND).
5. Connect a voltage meter across J5 (VBAT and PGND).
6. Set 23 V at KEPCO load output. Limit KEPCO to 6 A. Use load 2 to power EVM from the VOUT output.
7. Connect J5 to the EV2400. Connect J5 to the I
8. Install the jumpers as indicated in IO and Jumper Descriptions.
