ABSTRACT:
The standby electric supply comprises an accumulator which comprises multiple interconnected blocks, a switching portion that conditionally connects the accumulator to a load or to a charging current supply and a measurement and control portion that produces measurement results for describing the state of the accumulator and that controls the switching portion on the basis of the measurement results produced. The measurement and control portion is arranged to measure, at an initial time, the initial value of the open cell voltage of each block from the accumulator when charged and to produce a threshold value from the measured block specific initial value of the open cell voltage. The measured open cell voltage at an observed time different from the initial time is compared with the threshold value. If the measured block specific value of the open cell voltage has reached the threshold value, the switching portion is controlled to connect the accumulator to the charging current supply.
