Abstract
The present invention provides a new and novel method of and system for predicting remaining battery capacity. The present invention is based upon the ability to predict remaining battery capacity from noting the discharge characteristics over a relatively short period of time at the beginning of full discharge. In particular, the present invention has found correlation factors which can be used in combination with discharge characteristics early in the full discharge, to predict the remaining battery capacity to a predetermined end discharge voltage. The ability to predict remaining battery capacity to a predetermined end discharge voltage can be extremely valuable in preventing battery shut down by allowing early detection of potential problems. Further, the present invention relates to a system of monitoring batteries using the method, which system can be operated a t a remote location from the batteries.
