Battery presence testing

Wednesday, 30 June, 2004 | Supplied by: http://www.innovative-energies.com/



Innovative Energies' No-Break 3 battery backed-up DC power supply system employing 'smart' testing for battery presence does not rely solely on charge current sensing or power supply output interruption. The NB3 system continuously monitors charge current and initiates a full test if current falls below a set value for any reason; within a set time interval.

A preload is applied (should there be no standing load) and power module output voltage is then adjusted to allow unambiguous sensing and confirmation of battery presence (or absence) without compromising the integrity of the system. If no battery or a faulty battery is detected, normal supply is immediately resumed and an alarm is raised.
