Nicad Battery Tester

This is definitely not the battery tester you get with a DuraCell! It burns in and tests 500 Nicad batteries at a time, taking data on each battery as it is alternately charged and discharged. The batteries that are being tested here are the kind that are used in portable telephones.

To build this tester, we first designed a printed circuit board incorporating a PIC processor with an A/D converter. Each board controls the charging and discharging of two batteries in response to commands sent to it over an RS485 channel. A PC running a C program controls the system and collects the data for each battery.
