ABSTRACT:
A battery charger device and method including a charging circuit having a source of charging energy and connections for installing one or more batteries to be charged, the device having a controllable switch associated with each battery to be charged and a microprocessor for controlling the switches to establish a charging sequence of distinct repeated charging periods for each battery, a display device associated with each battery under control of a microprocessor for individually indicating the charging status of each battery, the microprocessor having inputs at which various parameters with respect to the batteries being charged are applied such as battery voltages, ambient temperatures and charging currents, the microprocessor being programmed to terminate a voltage charging operation with respect to any one or more of the batteries if the measured difference between the charging and non charging voltage of any one or more of the batteries during succeeding charging periods exceeds some predetermined value, or if the charging current, or the ambient temperature of the battery being charged is outside of a predetermined range. The present device and method may also include a back up termination means which responds to measurements of the battery voltage during succeeding charging periods and determines therefrom that on a predetermined number of succeeding cycles the condition of the battery voltage has changed by at least some predetermined amount.
