Abstract

834,022. Battery charging systems. HARMER, H. M., and COOK, F. J. Oct. 18, 1957 [July 23, 1956], No. 22759(56. Class 38 (4). An apparatus for charging a multi-cell battery without large variations in the terminal voltage comprises a charger C1 connected across the whole battery and supplying the mean current of a load X and a second charger C2 connected to one or a small number of cells in sequence through a stepping switch comprising a ratchet R and a pawl T operated by a coil M energized by normally closed contacts F of a relay G, F. The connections to the battery are changed by arms P, N and contacts K. Additional contacts E, operated by an extension U of the pawl, and H operated by a slowrelease relay coil D step the mechanism over an off contact L to which may be connected a counting device. The charger C2 may be of the constant-voltage type, with the coil G in series, or a constant-current or combined type with the coil G connected across its terminals. Each cell may be provided with a catalytic converter to recombine the gases produced by electrolysis. To increase the charging rate of C1 after a mains failure, the charger C1 and load X may be switched normally or automatically across part of the battery, a rectifier being connected across the switch to preserve continuity of current flow during changeover.
