Determining battery charge involves computing charge in first range of operation on basis of model computation in which measured and computed battery voltages are equalized by feedback

摘要

The method involves computing the state of charge of the battery in a first range of operation of the battery on the basis of a model computation in which a measured and a computed battery voltage are equalized by feedback. The first working range is adopted when a battery current or discharge current exceeds a minimum value. AN Independent claim is also included for the following: an arrangement for determining battery's state of charge.
