State-of-charge indicator for battery storage system, has lamps individually controllable for visualizing state-of-charge of battery storage system, where light colors of lamps are controllable according to state-of-charge

摘要

The indicator (2) has lamps (20-29) i.e. LED lamps, individually controllable for visualizing a state-of-charge of a battery storage system (1), where the indicator is arranged at an outer side of a housing (10) of the battery storage system. Light colors of the lamps are controllable according to a state-of-charge. The lamps are arranged in series, such as in a vertical row. The lamps are extended in a longitudinal direction of the housing. The lamps are actuated according to a charge of the battery storage system. Independent claims are also included for the following: (1) a battery storage system (2) a method for visualizing a charge of a battery storage system.
