Automatic charging of lead acid batteries - is computer based and clock signals are compared with programme

摘要

Charging arrangement designed to replace mechanical equipment which due to the complexity of the functions required, must be fragile, expensive and require regular maintenance. The type of application envisaged is that of security, telecommunications and electrically driven vehicles. System described can run complex charging requirements and is based on a clock source generating regularly spaced signals which, when counted and compared to a preset program, can initiate the required charging operations. The duration of such operations is controlled by monitors external to the basic circuit and feeding the computer using AND and OR circuits with relevant information such as state of charge of individual batteries.
