A method and an apparatus for rapidly charging a battery. The preferred charging method comprises applying one or more charging pulses (C1, C2), separated by a waiting period (CW~), with the las t charging pulse, if there are more than one, being followed by a second waiting period (CW2). This is then followed by a seri es of discharging pulses (D1, D2, D3), which are separated by waiting periods (DW1, DW2) and followed by a last waiting period (D W3) before the occurrence the next charging pulse (C1). The discharging pulses pulses preferably have a magnitude which is a pproximately the same as the magnitude of the charging pulses but which have a duration which is substantially smaller than th e duration of the charging pulses. Also disclosed are a method and an apparatus for thawing and charging a frozen battery, for for matting a new battery, for determining the state of formation of a battery, and for determining the state of charge of a battery. |
