Abstract
Arrangement for controlling the power supply to a load (,) fed from a rechargeable current source (,) of limited capacity, such as a battery, supplied with energy from a generator (,), a solar cell arrangement or the like and connected to the load (,) via a line (,) of undetermined resistance which connects to the load (,) via a terminal (,) at which voltage measurements can be performed. The arrangement is an electronic control arrangement (,) disposed adjacent to the load (,) and connected to the terminal (,). The electronic arrangement performs voltage measurements at said terminal in accordance with a predetermined program. In a series of such voltage measurements a first one is performed with the load (,) disconnected, whereas one or a plurality of measurements are performed with the load (,) connected. The first voltage measurement value represents the terminal voltage of the current source (,) at the start of the series of measurements. Said terminal voltage is then calculated from the latest measured voltage value at the terminal (,) prior to the connection of the load (,) and the first measured voltage value at the terminal (,) after the connection of the load (,). The latest measured voltage value at the terminal (,) prior to the connection of the load (,) is in turn updated for each new measured voltage value at the terminal (,).
