2 Test Summary
2.1 Equipment
2.1.1 Specify Equipment Needed to Perform Tests
1. Power Supplies (PS)
One power supply capable of supplying 12 V at 4 A (or above) is required. While this part can handle
larger voltage and current, it is not necessary for this procedure.
NOTE: If there is no display of current and voltage in this power supply, a separate current meter
and a separate voltage meter are required to measure the input current and input voltage,
respectively.
2. Battery Simulator (4-quadrant supply, constant voltage < 4.5 V)
A Kepco load: BOP 20–12 M, DC 0 to ±20 V, 0 to ±8 A (or higher), or equivalent.
NOTE: If there is no display of current and voltage in this electronic load, a separate current meter
and a separate voltage meter are required to measure the output current and output voltage,
respectively.
3. Meters
Six Fluke 75 multimeters, (equivalent or better)
or:
Four equivalent voltage meters and two equivalent current meters. The current meters must be
capable of measuring 8 A+ current.
NOTE: Only needed if required as described in Power Supplies (PS) and Battery Simulator .
4. Computer
A computer with at least one USB port and a USB cable. The bq25970EVM evaluation software must
be properly installed (bqStudio).
5. EV2x00 Communication Kit
The EV2x00 USB-based PC interface board.
