MCP1631HV Multi-Chemistry Battery Charger Reference Design
C.6
LAB EXERCISES
1. Startup the mikroC TM compiler and load the
“MCP1631HVBuckBoostBatteryChargerReferenceDesign.ppc” if it does not
load up automatically.
2. Startup MPLAB and load the
“MCP1631HVBuckBoostBatteryChargerReferenceDesign.mcw” workspace if it
does not start up automatically.
C.6.1
Li-Ion Only Exercise (single cell, 1200 mAh pack)
1. In the mikroC ? “Project Summary” frame, click on the “H files” branch to expand
the ‘.H’ file list.
2. Double click on the
“MULTICHEMISTRY_REF_DESIGN_BOARD_102_00232.H” file to open it.
3. Scroll through the header file and locate “#define LION_SUPPORT”.
Set it to “ENABLED”.
4. Scroll through the header file and locate “#define NIMH_SUPPORT”.
Set it to “DISABLED”.
5. Scroll through the header file and locate “#define LED_DRIVER_SUPPORT”.
Set it to “DISABLED”.
6. Scroll down to the “#IF (LION_SUPPORT == ENABLED) section of the header
file. The section contains Lithium Ion specific parameters. Note that there is a
Nickel Metal Hydride and LED Driver section also.
7. Set the LI_ION_CONDITION_CURRENT to 200 mAh. (Conditioning mode
current)
8. Set the LI_ION_CONDITION_VOLTAGE to 3000 mV. (Transition point from
Conditioning to CC mode)
9. Set the LI_ION_CHARGE_CURRENT to 1200 mAh. (CC mode current)
10. Set the LI_ION_CHARGE_TERMINATION_CURRENT to 84 mAh. (0.07C –
Termination Current for CV mode)
11. Save the file (File | Save).
12. Compile (Project | Build).
13. Open MPLAB and load the workspace if it is not already loaded. (File | Open
Workspace) {Source
Directory}\MCP1631HVBuckBoostBatteryChargerReferenceDesign.mcw
14. Import the new “MCP1631HVBuckBoostBatteryChargerReferenceDesign.hex”
file. (File | Import)
15. Download the file (Debugger | Program) and reset the processor (Debugger |
Reset | Processor Reset).
16. Run the new program (Debugger | Run).
17. Calibrate the Li-Ion Termination Voltage.
18. Disconnect and turn on the power supply and set the variable output voltage to
4.200V. Turn off the power supply.
19. Connect the fixed 12V supply (+) lead to the input connector (+) pin J1-1.
20. Connect the fixed 12V supply (-) lead to the input connector (-) pin J1-2.
21. Connect the 4.200V variable supply (+) lead to the battery connector (+) pin J2-1.
22. Connect the 4.200V variable supply (-) lead to the battery connector (-) pin J2-5.
23. Turn on the power supply.
