Battery charging condition i.e. charging time, determining method for battery-operated self-propelled dust collecting robot, involves activating level of total voltage activated as mail for actually available charging condition of battery

摘要

The method involves adding auxiliary voltage to a terminal voltage of a battery (AK) during operation of a battery-operated device by an adding device (ADD). The auxiliary voltage is obtained by multiplying flowing battery current with a battery-dependent resistance factor by a multiplication device (MUL). A level of total voltage obtained from the terminal voltage and the auxiliary voltage is activated as a mail for actually available charging condition of the battery based on a reference voltage assigned to the determined charging condition of the battery. An independent claim is also included for a circuit arrangement for executing the method for determining a charging condition of a battery.
