<p>PURPOSE:To prevent a storage battery from being charged excessively or from being discharged excessively and to make the life of the storage battery long by a method wherein the output voltage of an AC generator is controlled to a value which is optimum for charging the storage battery. CONSTITUTION:A voltage regulating device 7, with a built-in microcomputer, which is connected across an AC generator 1A and a storage battery 3 estimates a storage-battery liquid temperature on the basis of detection signals from a terminal-voltage detection terminal 8 for the storage battery, from an intake air temperature sensor 9 and from a cooling-water temperature sensor 10. It controls that the AC generator generates a charging voltage which is optimum for the storage battery.</p> |
