PCT No. PCT/SE81/00376 Sec. 371 Date Aug. 12, 1982 Sec. 102(e) Date Aug. 12, 1982 PCT Filed Dec. 16, 1981 PCT Pub. No. WO82/02121 PCT Pub. Date Jun. 24, 1982.The invention relates to a method of charging an electrical accumulator battery (16) by means of solar panels (11-14) with solar-cells. The battery (16) is charged by means of two or more solar panels (11-14) included in charging branches connected in parallel, at least one charging branch being permitted to charge the accumulator battery to a higher voltage than the other charging branch or branches. Only the charging branch or branches which charge to the highest voltage are permitted to deliver current to the acccumulator battery (16) during maintenance charging, when the accumulator battery is fully charged. A device for carrying out the method consists of charging branches (11-21, 12-22 , 13-23, 14-24) comprising at least one solar-cell panel and connected in parallel, the charging branches being adapted to deliver charging current at different voltages. At least one voltage is permitted to be higher than the other or others. The charging branch (14-24) which delivers the highest voltage is adapted to deliver a voltage which is somewhat higher than the voltage of the fully charged accumulator battery. |
