Hardware Setup

Use the following list to set up the EVM testing equipment as shown in the figure below:

  1. Install or customize EVM jumper connections as explained in Table 2-2.

    Only 1 shunt must be installed for each group of headers: JP8-JP11, JP12-JP15, JP17-JP20 to set the default cell count, cell voltage and pre/charge/term current, respectively. The pins are read and register defaults set at POR from either VIN or battery or after ILIM_HIZ is pulled high. The cell count and voltage product sets the default battery regulation voltage and minimum system voltage.

  2. Set PS #1 for 12V DC, 3A current limit and then turn off the supply.
  3. Connect the output of PS#1 in series with a current meter to J2 (VPWR and PGND).
  4. Connect a voltage meter across TP10 (VIN_K) and any AGND test point or across J2.
  5. Turn on Load #1, set to constant voltage mode, and output to 5V. Disable Load.
  6. Connect a voltage meter across TP15 and TP16 to measure the voltage across the ACx sense resistor. The measurement divided by the sense resistor gives IIN/IIN_REV input/output current.
  7. Connect a voltage meter across TP14 (SRN) and any AGND test point or across the J3 connector to measure battery voltage.
  8. Connect a voltage meter across TP8 and TP9 to measure the voltage across the SRx sense resistor. The measurement divided by the sense resistor gives battery current.
  9. Connect the EV2400 or EV2500 USB interface board to the computer with a USB cable and from I2C port to J5 with the 4-pin cable.
