Impact of the current and the temperature variation on the Ni-Cd battery functioning

In electrical systems, the battery, which is a device converting the stored energy as chemical to electrical one, is composed of one or more electrochemical cells. Nickel Cadmium batteries (Ni-Cd) are used in different applications as emergency lighting, mobile phones and others. The "high surge current" obtained in these batteries is depending on the internal resistance which is "relatively low". This paper describes the Ni-Cd battery and its functionality. It represents two models of the battery and the simulation of its charging and discharging modes. The load current and temperature influence on the battery functioning is also treated.
