The threshold can be deactivated by not using any of the 0Ω jumpers. The threshold has then the
maximum possible voltage.
5.1.3 Activation and Deactivation of the Charger
The charging voltage can be deactivated by using the jumper J3 in it’s OFF position. In position ON
the charging voltage is activated. This allows control for certain tests.
5.1.4 Sequentiell Discharging of the Batteries
A sequentiell discharging of the battery makes no sense from the energetical point of view. With a
parallel discharging the battery has less power loss, due to a lower current from each battery. This
works only when Smart Batteries are used with identical cell configuration and chemistry. (e.g.
4S3P with LiIon)
Despite these facts, if an application needs a sequentiell discharging, then there are 2 ways to
realise it.
One possibility is to use different batteries with different cell configuration or chemistry, which
leads to different battery voltages. In this case there will be always a sequentiell discharging done,
because the system always use the battery with the highest voltage. Only if the batteries have an
nearly similar voltage, then they are discharged equally.
Another possibility is an extension of the circuit of the SBS Manager. You can order an application
note for this topic from Kontron.
