At present, Nickel Hydrogen batteries are tested at Marshall Space Flight Center (MSFC) in support of the Hubble Space Telescope (HST) program. In previous years, Nickel Cadmium batteries were tested at MSFC in support of HST. The Nickel Cadmium Battery Expert System-2 (NICBES-2) was employed on the HST six battery test bed to evaluate the performance of the HST Electrical Power System (EPS). With the beginning of testing of the nickel hydrogen six battery test bed, NICBES-2 had to be converted to NICkel Hydrogen Battery Expert System (NICHES). This paper describes the conversion of the NICBES-2 to the NICHES as well as future plans for NICHES.
