Perth, Australia: Proceedings of the International Conference on Power Electronics, Drives and Energy Systems, 1998. 786--791.http://hdl.handle.net/10092/1690In electric vehicles it is important to know the state of charge of the batteries in order to prevent vehicle strandings and to ensure that the full range of the vehicle is exploited. It is also useful to know state of health information about the batteries to predict when the batteries need replacing. This paper describes a battery monitoring system that is able to calculate the state of charge and state of health of multiple batteries in a battery bank. It has been designed specifically to monitor lead-acid batteries in an electric car environment using noninvasive measurement techniques. The monitor incorporates an adaptive monitoring method, which is based on coulometric measurements when the batteries are under load and predicted open circuit voltage measurements under no-load conditions.enConference Contributions - OtherFields of Research::290000 Engineering and Technology::290900 Electrical and Electronic Engineering::290901 Electrical engineeringFields of Research::290000 Engineering and Technology::290400 Automotive Engineering
