A challenge in connection with electrical vehicles is to obtain relevant information about batteries' remaining driving distance, charge status, aging, temperature and charging processes. We have developed a sensing technology judged to be very suitable to obtain such information and which is robust, compact, miniaturizable, and suitable for multiplexing - several quantities measurable with one sensor chip. The need of such sensors is large as confirmed in discussions with Volvo Group (Volvo Technology AB) and by literature and patent search. This application was discovered recently and is subject to a patent application. Therefore no details can be given just now, but can be provided after April 7 (this situation has been discussed with Hans-Olof Dahlberg). In the project, which is a pre-study, the concept will be tested in a lab battery model.
