1,186,942. Charging batteries. GULTON INDUSTRIES Inc. 19 April, 1967 [28 April, 1966], No. 18030/67. Heading H2H. [Also in Division H1] A battery system comprises a sealed secondary battery and charge control means for feeding charging current thereto at a high rate, the battery containing means responsive to the generation of O2 which on attainment of a substantially fully charged condition causes the operation of the charge control means to terminate the charging and allow the rapid consumption of the O2. As described (Fig. 1) an O2- consuming electrode 16 in the battery 1 is connected to an external control terminal 18 with current responsive means connected between the control terminal 18 and the negative terminal 12 of the battery responding at a given trip level, corresponding to the desired level of charge, to discontinue the charging enabling the O2 to be rapidly consumed. The current flowing through the current responsive means increases as the O2 pressure builds up in the battery until at the fully charged condition it reaches the trip level. The charge control/ current sensing means can be a relay controlled battery charge system (Fig. 12, not shown). Alternatively it can be a magnetic amplifier controlled system (Fig. 13) in which the current responsive means 20 is a pair of magnetic switches including control windings 20a, 20b which are respectively coupled to gate windings 23a, 23b which constitute the charge control means by being wound respectively on cores 23a<1>, 23b<1> of magnetic material having a rectangular hysteresis characteristic. If the system is installed in an artificial satellite charging current can be supplied by solar cells. |
