This avoids excess temperature rise and yet assures fully charged batteries. Figure 4-1: Charge characteristics of a NiCd cell. These cell voltage, pressure and temperature characteristics are similar in a NiMH cell. Interspersing discharge pulses between charge pulses improves the charge acceptance of nickel-based batteries. Commonly referred to as ‘burp’ or ‘reverse load’ charge, this charge method promotes high surface area on the electrodes, resulting in enhanced performance and increased service life.
Because of its low energy density, this battery type is not used for small portable devices. In the following sections various charging needs and charging methods are studied. The charging techniques of different chargers are examined to determine why some perform better than others. Since fast charging rather than slow charging is the norm today, we look at well-designed, closed loop systems, which communicate with the battery and terminate the fast charge when certain responses from the battery are received.
Paralleling is also necessary if pack dimensions restrict the use of larger cells. Among the battery chemistries, Li-ion lends itself best to parallel connection. Protection Circuits Most battery packs include some type of protection to safeguard battery and equipment, should a malfunction occur. The most basic protection is a fuse that opens if excessively high current is drawn. Some fuses open permanently and render the battery useless once the filament is broken; other fuses are based on a Polyswitch™, which resembles a resettable fuse.
