Abstract

A voltage-temperature limit circuit for the Ni-H2 battery is designed and analyzed for the maximum and the minimum voltage deviations at the worst case of the EOL(end of life). It is demonstrated that the magnitude of voltage deviations due to circuit device tolerances are kept less than 0.3v at the worst case. The maximum and the minimum battery voltages are simulated for the environmental temperature range of $0^{\circ}C-30^{\circ}C$ by using MATHCAD. They are 34.67v and 29.851v, respectively.
