Abstract
A controller (,) controls the application of charge pulses and discharge (depolarization) pulses to a battery (,) via a charge pulse circuit (,) and a discharge pulse circuit (,). A feedback circuit (,) allows the controller to monitor and adjust the charging process. A wave shaper (,) shapes the waveform of the charge pulses so as to limit the rise time of the charge pulses and thereby reduce reflected voltages and currents. A limiter (,) disables the charging circuit in the event that the controller should specify a charge pulse having an excessive duration or a continuous duration. Another limiter (,) limits the duration of the discharge pulses in the event that the controller should specify a discharge pulse having an excessive duration or a continuous duration. The charge pulse circuit is disabled whenever the controller specifies the application of a discharge pulse, and the discharge circuit is disabled whenever the controller specifies the application of a charge pulse. This prevents the simultaneous application of a charge pulse and a discharge pulse.
