Intelligent NiCd Charger Avoids Battery Damage From High Currents
by Joseph Diecidue, electronics technician, Wentworth Institute of Technology, Boston, Mass. and Robert S. Villanucci, professor, Electronic Design, May 08 2008
Focus:
When fast charging a NiCd battery, the high charging current raise the temperature and pressure within the NiCd cells, potentially resulting in damage or destruction of the battery. To protect the battery, a charging circuit monitors the temperature differential between the battery's surface and the ambient and reduces charging current as the temperature differential increases.
