DEFINITION

Classification: 320/146

Hysteresis type (e.g., antichattering, etc.):

(under subclass 139) Subject matter including control means for starting and stoppingcharging (or changing the rate of charging) of a battery or cell at, respectively, different battery or cell voltage levels.

(1) Note. Typically, a battery-voltage control "window" is used to prevent instability or oscillation in a charger on/off cycle or a fast charge/trickle charge cycle.
