Abstract

692,508. Self-contained supply systems; charging and discharging batteries; automatic voltage control systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 17, 1950 [Nov. 19, 1949], No. 28135/50. Class 38 (iv). In an electric lighting system for electrically driven vehicles having an alternator 1 driven from a power source on the vehicle, a battery reserve set 3, a parallel connected lighting load circuit 4 which may comprise discharge lamps and a battery charging circuit 2, and switchover means 5a, 5b for alternatively switching the load 4 to the alternator 1 or the battery reserve set 3, at least two automatic regulators are provided, of which one is a field regulator 8 for controlling the alternator voltage to a value suitable for either the load (as shown) or the battery charging circuit, and another provides a suitable voltage for the remaining one of the two circuits and is connected between the alternator and such circuit. Should the alternator voltage fall, e.g. due to slowing of the vehicle, a voltage-sensitive relay energizes the switch-over means to change the load supply from the alternator to the battery, Fig. 1 (not shown), and to avoid the resulting momentary supply interruption a relay 12 is energized by the regulator 8 as it approaches the limit of its ability to maintain the required load voltage, whereupon the relay 5a connects the battery 7 in parallel with the alternator 1. A timing relay 11a subsequently energizes the relay 5b to disconnect the alternator from the load. The battery 7 may be charged through a transformer 2a, transductor 2b and rectifier 2c at constant voltage, with maximum current limitation. A current transformer 10 influences the charging current to limit the total current to the capacity of the alternator. An inverter 9 and a further regulator 6 (not shown) may be connected between the battery and the load. A number of forms of voltage and current control by the regulators are disclosed in the Specification.
