BESTEMMELSE AV ET BATTERIS LADETILSTAND

摘要

This operates on the principle that the values of the battery terminal voltage and of the voltage drop at a load-current carrying shunt 6 are converted 8, 9 into digital values and added 11. The total value is multiplied 14 by a digital value dependent 24 on the battery electrolyte temperature and by a digital value dependent 23 on the magnitude of the load current J, to provide an indication 17 of the battery state of charge. Each individual cell 3 of the battery 1 may be separately monitored via multiplexer 26.
