Abstract
An aleatory source of energy, e.g., a battery of photocells (1), supplies energy to a load (5) and to a storage battery (3). When the source is supplying more energy than is being drawn by the load, the storage battery is charged; when the source is supplying less than the demand, the shortfall is made up by drawing energy from the storage battery. The state of charge of the storage battery is monitored by a meter (8) which governs a regulator (7). Once the battery is charged to a predetermined threshold, the amount of current it draws from the source is regulated, and energy supplied by the source in excess of the combined requirements of the load and of battery charging is diverted to a storage means (6) other than the storage battery (e.g., a mains electricity supply grid). The flows of energy to both the battery and the other storage means are controlled by the regulator (7) as a function of the state of charge of the battery.
